pages.json 页面路由

The pages.json file is used to configure uni-app globally, to determine the path of the page file, window style, native navigation bar, native tabbar at the bottom, etc.

It is similar to the page management part of app.json in the WeChat MiniApp. Note that the application for location permissions and other content that originally belonged to app.json are configured in the manifest in uni-app.

pages

uni-app configures which pages the application consists of through the pages node. The pages node receives an array, and each item in the array is an object, and its attribute values are as follows:

Attribute	Type	Default	Description
path	String		配置页面路径
style	Object		配置页面窗口表现，配置项参考下方 pageStyle
needLogin	Boolean	false	是否需要登录才可访问

Tips：

• The first item of the pages node is the application entry page (i.e. the home page)
• Add/reduce pages in the application, you need to modify the pages array
• The file name ** does not need to write a suffix **, the framework will automatically find the page resources under the path

Code sample:

开发目录为：

	
┌─pages
│  ├─index
│  │  └─index.vue
│  └─login
│     └─login.vue
├─static
├─main.js
├─App.vue
├─manifest.json
└─pages.json
	

You need to fill in pages.json

{
    "pages": [
        {
            "path": "pages/index/index",
            "style": { ... }

    ...
  ]
}

Notice

• Alipay MiniApp must use the image link address of https when using titleImage. It needs to be debugged on the real machine to see the effect, and there is no effect in the Alipay developer tool

Custom navigation bar use attention

当navigationStyle设为custom或titleNView设为false时，原生导航栏不显示，此时要注意几个问题：

• 非H5端，手机顶部状态栏区域会被页面内容覆盖。这是因为窗体是沉浸式的原因，即全屏可写内容。uni-app提供了状态栏高度的css变量--status-bar-height，如果需要把状态栏的位置从前景部分让出来，可写一个占位div，高度设为css变量。

<template>
    <view>
        <view class="status_bar">
            <!-- This is the status bar -->
        </view>
        <view> 状态栏下的文字 </view>
    </view>
</template>
<style>
    .status_bar {
        height: var(--status-bar-height);
        width: 100%;
    }
</style>

• If the native navigation bar cannot meet the needs, it is recommended to use uni ui's custom navigation bar NavBar. This front-end navigation bar automatically handles the status bar height occupation problem.
• When the front-end navigation bar is paired with native pull-down refresh, there will be problems, including
  • Under the WeChat MiniApp, iOS needs to be pulled longer to see the three points of pull-to-refresh, while Android pulls down from the top of the screen and cannot pull down from the bottom of the navigation bar. If you must pull down from the front-end navigation bar, you can only give up the native pull-down refresh under the MiniApp, pure front-end simulation, refer to mescroll plugin,but this It is easy to have performance problems. At present , the MiniApp platform itself does not provide a better solution
  • Under App and H5, the native pull-down refresh provides circle style, you can specify the offset offset (configured under app-plus in pages.json), and customize the drop-down circle where it appears. There are examples in the extension component of hello uni-app.
• On the non-H5 side, the front-end navigation cannot cover the native components. If the page has native components such as video, map, textarea (MiniApp only), etc., the navigation bar will be covered when scrolling
  • If it is a MiniApp, you can use cover-view as the navigation bar to avoid coverage problems
  • If it is under App, it is recommended to use titleNView or subNVue for a better experience
• The rendering speed of the front-end components is not as good as that of the native navigation bar. The native navigation can be rendered during the animation to ensure that there is no white screen during the animation. However, when using the front-end navigation bar, the entire page may be blank during the animation of the new form. The lower the The phone at the end is more obvious.
• The above discussion is the front-end custom navigation bar, but on the App side, the native navigation bar also provides richer customization than the MiniApp navigation
  • titleNView: Provide more configurations for the native navigation bar, including custom buttons, scrolling gradient effects, search boxes, etc., see titleNView for details
  • subNVue: Use nvue native rendering, develop all layouts by yourself, with all customization flexibility. See subNVue for details
• After the native navigation bar is disabled on the page, if you want to change the foreground font style of the status bar, you can still set the navigationBarTextStyle property of the page (can only be set to black or white). If you want to set the status bar color separately, you can use plus.navigator.setStatusBarStyle setting on the App side. Note that some low-end Android phones (4.4) do not support setting the foreground color of the status bar.

In view of the above problems, try to use native navigation when native navigation can solve business needs. Sometimes it is even necessary to sacrifice some less important needs. Under App and H5, uni-app provides flexible solutions: titleNView, subNVue, or the whole The page uses nvue. But under the MiniApp, because of its own limitations, there is no good solution. If necessary, you can also use conditional compilation to split the processing.

Tips

• The page supports disabling the native navigation bar by configuring navigationStyle as custom or titleNView as false. Once native navigation is disabled, please read Custom Navigation Considerations.
• When the type value of titleNView is transparent, the navigation bar is a scrolling transparent gradient navigation bar. By default, there are only buttons. After scrolling, the background color of the title bar and the title text will appear gradually. Custom buttons are not supported to set the color attribute; When type is float, the navigation bar is a floating title bar. At this time, the page content is pushed up to the top of the screen, including the status bar, but the navigation bar is suspended above the page. Generally, the background of the navigation bar will be set at the same time in this scenario The color is the rgba translucent color.
• App-nvue 2.4.4+ supports when the type value of titleNView is transparent
• 在 titleNView 配置 buttons 后，监听按钮的点击事件，vue 页面及 nvue 的weex编译模式参考：uni.onNavigationBarButtonTap
• 在 titleNView 配置 searchInput 后，相关的事件监听参考：onNavigationBarSearchInputChanged 等
• configurable via [<navigation-bar>(/component/navigation-bar)]
• If the button of the native navigation bar under the app uses a font icon, pay attention to check whether the name of the font library (font-family) uses the default iconfont. This name is a reserved word and cannot be used as the name of an externally imported font library. It needs to be adjusted to A custom name, otherwise it cannot be displayed.
• To learn about the development methods of various navigation bars, please read Navigation Bar Development Guide

Tips

• It is recommended to use font icons for the text of buttons. If Chinese characters or English are used, it is recommended to change the font to a smaller size, otherwise the length of the text will be too close to the right margin of the screen.
• App platform, buttons are dynamically modified, see details
• App platform, dynamic modification of buttons corner mark, see template in hello uni-app - top navigation title bar - navigation bar with red dot and corner mark
• App platform, set the dynamic modification of searchInput text, API see Documentation. Note that text cannot be set in the disable state, and placehold does not support dynamic settings for the time being
• For the H5 platform, if you need to implement the above dynamic modification, you need to modify it through dom operation in conditional compilation

Native subform

subNVues is a native subwindow for vue pages. It is used to solve the hierarchical coverage in the vue page in the App and the flexible customization of the native interface.

It is not a full-screen page, nor a component, but a native subform. It is an nvue page, rendered with the weex engine, which provides more powerful native layout capabilities than cover-view, plus.nativeObj.view, and is convenient for customizing native navigation or overlaying native maps, videos, etc. Please read subNVues Development Guide

subNVue can also be used in nvue pages. But currently it is not supported under pure nvue (render is native).

Attribute	Type	Description

pull down to refresh

Under the App platform, you can customize the partial pull-to-refresh configuration page->style->app-plus->pullToRefresh.

Attribute	Type	Default	Description
support	Boolean	false	whether to enable the pull-down refresh function of the window
color	String	#2BD009	The format of the color value is "#RRGGBB", only the "circle" style pull-down refresh supports this property.
style	String	The Android platform is circle; the iOS platform is default.	Possible values: "default" - classic pull-down refresh style (the page content follows when you pull down and drag); "circle" - circle style pull-down refresh control style (only the refresh control follows when you pull down and drag).
height	String		The drag height of the window's pull-down refresh control to enter the refresh state. Support percentage, such as "10%"; pixel value, such as "50px", does not support rpx.
range	String		The range that the window can drop down and drag. Support percentage, such as "10%"; pixel value, such as "50px", does not support rpx.
offset	String	0px	The starting position of the pull-to-refresh control. Only valid for the "circle" style pull-down refresh control, it is used to define the starting position of the refresh control when it is pulled down. Support percentage, such as "10%"; pixel value, such as "50px", does not support rpx. If a non-native title is used and a native pull-down refresh is required, the circle method is generally used and the offset is adjusted to the height of the custom title
contentdown	Object		Currently supports one attribute: caption——the title content displayed on the control when it is pulled down to refresh. Only valid for "default" style pull-to-refresh controls.
contentover	Object		currently supports one attribute: caption——pull down to refresh the title content displayed on the control when the refreshable state is released. Only valid for "default" style pull-to-refresh controls.
contentrefresh	Object		currently supports one attribute: caption——pull down to refresh the title content displayed on the control when it is in the refresh state. Only valid for "default" style pull-to-refresh controls.

Pull down to refresh use note

• When enablePullDownRefresh and pullToRefresh->support are set at the same time, the latter takes precedence.
• If you want to enable pull-down refresh on both the App and the MiniApp, please configure the enablePullDownRefresh property of the page to true.
• If you only want to enable pull-to-refresh on the App, do not configure the enablePullDownRefresh property of the page, but configure pullToRefresh->support to true.
• When the native pull-down refresh is enabled, the scroll-view with full screen height should not be used in the page. When dragging the content down, the pull-down refresh will be triggered first instead of scroll-view scrolling
• The starting position of the native pull-to-refresh is below the native navigation bar. If the native navigation bar is canceled and a custom navigation bar is used, the native pull-to-refresh position will be at the top of the screen. If you want to pull under the custom navigation bar, you can only use the pull-down refresh of the circle method, and set the offset parameter to adjust the starting position of the circle circle to the bottom of the custom navigation bar. There are examples in the extension component of hello uni-app.
• If you want to implement more complex pull-down refreshes on the app side, such as pulling down a special graphic like Meituan and JD App, you can use nvue's <refresh> component. From HBuilderX 2.0.3+, you can experience the news template by selecting a new project
• If you want to implement pull-down refresh on the Vue page through the web front-end technology, there are examples in the plug-in market, but the performance of the front-end pull-down refresh is not as good as the original one, and the complex and long list will be very stuck
• On iOS, the pull-down refresh in default mode is bound to the bounce rebound. If bounce:none is set, the default pull-down refresh cannot be used

code example

{
    "pages": [
        {
            "path": "pages/index/index", //首页
            "style": {
                "app-plus": {
                    "pullToRefresh": {
                        "support": true,
                        "color": "#ff3333",
                        "style": "default",
                        "contentdown": {
                            "caption": "下拉可刷新自定义文本"
                        },
                        "contentover": {
                            "caption": "释放可刷新自定义文本"
                        },
                        "contentrefresh": {
                            "caption": "正在刷新自定义文本"
                        }
                    }
                }

	// There is no need to import here, and there is no need to register the uni-list component in components. It can be used directly in the template
	export default {

路径规范指：

1. 安装在项目根目录的components目录下，并符合components/组件名称/组件名称.vue
2. 安装在uni_modules下，路径为uni_modules/插件ID/components/组件名称/组件名称.vue

工程目录：

	
┌─components
│  └─comp-a
│    └─comp-a.vue      符合easycom规范的组件
└─uni_modules          [uni_module](/plugin/uni_modules.md)中符合easycom规范的组件
   └─uni_modules
     └─uni-list
       └─components
         └─uni-list
           └─ uni-list.vue
	

不管components目录下安装了多少组件，easycom打包会自动剔除没有使用的组件，对组件库的使用尤为友好。

The component library is installed in batches, used at will, and automatically packaged on demand. Take the official uni-ui as an example, select the uni-ui project template on the HBuilderX new project interface, just type u on the page, pull out a large number of component code blocks, select directly, and you can use it. Greatly improve development efficiency and lower the threshold for use.

In the uni-app plug-in market, download components that conform to the components/component name/component name.vue directory structure, and you can use them directly.

自定义easycom配置的示例

easycom is automatically enabled and does not need to be manually enabled. When necessary, you can personalize settings in the easycom node of pages.json, such as disabling automatic scanning, or customizing the strategy of scanning and matching components. Set the parameters as follows:

Attribute	Type	Default Value	Description
autoscan	Boolean	true	Whether to enable auto-scanning, after it is enabled, it will automatically scan components that match the directory structure of components/component name/component name.vue
custom	Object	-	Customize component matching rules in a regular way. If autoscan does not meet your needs, you can use custom to customize the matching rules

如果你的组件，不符合easycom前述的路径规范。可以在pages.json的easycom节点中自行定义路径规范。

If you need to match the vue files in node_modules, you need to use the matching rule in the form of packageName/path/to/vue-file-$1.vue, where packageName is the installed package name, /path/to/vue-file -$1.vue is the path of the vue file in the package.

"easycom": {
  "autoscan": true,
  "custom": {
    "^uni-(.*)": "@/components/uni-$1.vue", // 匹配components目录内的vue文件
    "^vue-file-(.*)": "packageName/path/to/vue-file-$1.vue" // 匹配node_modules内的vue文件
  }
}

说明

• easycom方式引入的组件无需在页面内import，也不需要在components内声明，即可在任意页面使用。
• easycom方式引入组件不是全局引入，而是局部引入。例如在H5端只有加载相应页面才会加载使用的组件。
• 在组件名完全一致的情况下，easycom引入的优先级低于手动引入（区分连字符形式与驼峰形式）。
• 考虑到编译速度，直接在pages.json内修改easycom不会触发重新编译，需要改动页面内容触发。
• easycom只处理vue组件，不处理小程序专用组件（如微信的wxml格式组件）。不处理后缀为.nvue的组件。因为nvue页面引入的组件也是.vue组件。可以参考uni ui，使用vue后缀，同时兼容nvue页面。
• nvue页面里引用.vue后缀的组件，会按照nvue方式使用原生渲染，其中不支持的css会被忽略掉。这种情况同样支持easycom。
• vue 与 uvue 组件优先级，详见。

Bug & Tips

• HBuilderX 3.96 版本以下uni-app x项目，当页面文件名与easycom的组件名一样时，会渲染异常，可以通过调整页面文件名规避该Bug。

tabBar

If the application is a multi-tab application, the tabBar configuration item can be used to specify the first-level navigation bar and the corresponding page displayed when tab switching.

Providing tabBar configuration in pages.json is not only to facilitate rapid development of navigation, but more importantly, to improve performance on the App and MiniApp side. On these two platforms, the underlying native engine can directly read the tabBar information configured in pages.json and render native tabs without waiting for the js engine to initialize when starting.

Tips

• When setting position to top, the icon will not be displayed
• The list in the tabBar is an array, and only a minimum of 2 and a maximum of 5 tabs can be configured, and the tabs are sorted according to the order of the array.
• Tabbar switching may not be rendered in time when it is loaded for the first time. You can pop up a waiting snowflake in the onLoad life cycle of each tabbar page (hello uni-app uses this method)
• After the tabbar page is displayed once, it will be kept in memory. Switching the tabbar page again will only trigger the onShow of each page, and will not trigger onLoad again.
• The tabbar at the top is currently only supported on the WeChat MiniApp. If you need to use the top tab, it is recommended not to use the top setting of the tabbar, but to make the top tab yourself, please refer to hello uni-app->template->top tab.

tabbar FAQ

• See Interface-Interface-tabbar for the js api of the tabbar, which can realize dynamic display and hiding (such as the pop-up layer cannot cover the tabbar), content modification (such as international Transformation), item plus corner mark and other functions. There are also examples in the hello uni-app.

• See onTabItemTap of the page life cycle for the item click event of the tabbar.

• The code jumps to the tabbar page, the api can only use uni.switchTab, cannot use uni.navigateTo, uni.redirectTo; use the navigator component open-type="switchTab" must be set when jumping

• The default height of the tabbar is different on different platforms. The default height of the App side is adjusted from 56px to 50px since HBuilderX 2.3.4, which is unified with the H5 side. Developers can also set the height by themselves and adjust it back to 56px. See details

• The tabbar is a div simulation on the H5 side, which is part of the front-end screen window. If you want to use the bottom positioning method, you should use the css variable --window-bottom, such as a button floating 10px above the tabbar, the style is as followsbottom: calc(var(--window-bottom) + 10px)

• An example of a tabbar template with a + sign in the middle, Reference. It can cross the end, but the + sign is not raised. If the middle is raised, configure the midButton of the tabbar.

• If you need to log in first and then enter the tab page, you don’t need to set the login page as the homepage, the homepage is still the tabbar page, you can refer to [Cloud-integrated login template](https://ext.dcloud.net.cn/plugin? id=13)

• The problem that the front-end pop-up mask layer cannot block the tabbar, and the tabbar is dynamically hidden during cross-end processing. You can use plus.nativeObj.view or subNVue on the App side to make pop-ups and masks. You can refer to this example of the sharing menu of native icons at the bottom

• Wechat MiniApp simulator version 1.02.1904090 has a bug. After zooming the simulator page percentage, the tabbar will freeze after clicking multiple times. There is no problem with the real machine, please pay attention when using it. See details

• On PC widescreen, when the page has a multi-window structure such as topWindow, leftWindow, or rightWindow, if you want to change the display position of the tabbar, please use [custom-tab-bar component](https://uniapp.dcloud.io/component /custom-tab-bar) configuration, if you want to hide the tabbar, you can use the following css (the advantage is that it can be linked with leftwindow and other forms):

    .uni-app--showleftwindow + .uni-tabbar-bottom {
    	display: none;
    }
  

code example

"tabBar": {
	"color": "#7A7E83",
	"selectedColor": "#3cc51f",
	"borderStyle": "black",
	"backgroundColor": "#ffffff",
	"list": [{
		"pagePath": "pages/component/index",
		"iconPath": "static/image/icon_component.png",
		"selectedIconPath": "static/image/icon_component_HL.png",
		"text": "组件"
	}, {
		"pagePath": "pages/API/index",
		"iconPath": "static/image/icon_API.png",
		"selectedIconPath": "static/image/icon_API_HL.png",
		"text": "接口"
	}]
}

Custom tabbar

The native tabBar is a relatively fixed configuration method, which may not satisfy all scenarios, which involves customizing the tabBar.

But note that except for the H5 side, the performance experience of the custom tabBar will be lower than that of the native tabBar. Do not customize the app and MiniApp unless necessary.

• Custom tabBar component on the H5 side: There is no concept of higher performance of the native tabBar on the H5 side, and the common tabBar under widescreen is at the top instead of the bottom. At this time, you can use [custom-tab-bar component](https://uniapp .dcloud.io/component/custom-tab-bar) to customize
• Ordinary custom tabBar: use view to draw tabBar by yourself. If the page is multi-page, switching the tabBar will not keep the bottom tabBar always displayed. Therefore, it is recommended to use the single-page method in this case. In the single-page mode, if it is a complex page, the application performance will drop significantly, and the page complexity needs to be reduced. If it is on the App side, the performance of nvue single page will be significantly higher than that of vue page
• WeChat MiniApp custom tabbar: WeChat provides a solution to customize tabBar based on webview. This function has a poor experience and is not recommended. If you want to use it, refer to WeChat Documentation,create a custom-tab-bar directory at the root of the project, and pay attention to the The code is wxml, wxss, not vue, and the uni-app compiler will directly copy the directory to the WeChat MiniApp
• There is only one native tabbar and it is on the home page. If you need tabs on the second-level page, you need to write a view to achieve it. Generally, the more suitable navigation for secondary pages is segment component

condition

The startup mode configuration takes effect only during the development period, and is used to simulate the scenario of direct access to the page, such as: after the MiniApp is forwarded, the user clicks on the opened page.

Property Description:

Attribute	Type	Required	Description
current	Number	Yes	the current active mode, the index value of the list node
list	Array	yes	list of boot modes

list description:

Attribute	Type	Required	Description
name	String	yes	boot mode name
path	String	是	启动页面路径
query	String	否	启动参数，可在页面的 onLoad 函数里获得

Note: You can directly open the configuration page when running on the real machine in the app. You need to manually change the compilation mode in the WeChat developer tools, as shown in the figure below:

Code sample:

"condition": { //模式配置，仅开发期间生效
	"current": 0, //当前激活的模式（list 的索引项）
	"list": [{
			"name": "swiper", //模式名称
			"path": "pages/component/swiper/swiper", //启动页面，必选
			"query": "interval=4000&autoplay=false" //启动参数，在页面的onLoad函数里面得到。
		},
		{
			"name": "test",
			"path": "pages/component/switch/switch"
		}
	]
}

subPackages

Subpackage loading configuration, this configuration is the subpackage loading mechanism of the MiniApp.

Because MiniApp have size and resource loading limitations, each MiniApp platform provides a subpackage method to optimize the download and startup speed of MiniApp.

The so-called main package is to place the default startup page/TabBar page, and all subpackages need to use public resources/JS scripts; and the subpackages are divided according to the configuration of pages.json.

When the MiniApp is started, the main package will be downloaded by default and the pages in the main package will be launched. When the user enters a page in the subpackage, the corresponding subpackage will be downloaded automatically, and then displayed after the download is complete. At this time, there will be a waiting prompt on the terminal interface.

App defaults to the whole package. Starting from uni-app 2.7.12+, it is also compatible with subpackage configuration of MiniApp. Its purpose is not to speed up the download, but to speed up the startup when the home page is vue. To enable subcontracting under App, in addition to configuring subcontracting rules in pages.json, you also need to set subcontracting settings on the app side in the manifest. For details, see: https://uniapp.dcloud.io/collocation/manifest?id=app-vue-optimization

The subPackages node receives an array, each item in the array is a sub-package of the application, and its attribute values are as follows:

Attribute	Type	Required	Description
root	String	Yes	the root directory of the subpackage
pages	Array	Yes	What pages are the subpackages composed of? The parameters are the same as pages

Notice:

• The path of pages in subPackages is a relative path under root, not a full path.
• The size of each subpackage of the WeChat MiniApp is 2M, and the total volume cannot exceed 20M.
• The size of each subpackage of the Baidu MiniApp is 2M, and the total volume cannot exceed 8M.
• The size of each subpackage of the Alipay MiniApp is 2M, and the total volume cannot exceed 8M.
• QQ小程序每个分包的大小是2M，总体积一共不能超过24M。
• 抖音小程序每个分包的大小是2M，总体积一共不能超过16M（抖音小程序基础库 1.88.0 及以上版本开始支持，抖音小程序开发者工具请使用大于等于 2.0.6 且小于 3.0.0 的版本）。 -The size of each subpackage of the Kuaishou MiniApp is 2M, and the total volume cannot exceed 24M.
• 分包下支持独立的 static 目录，用来对静态资源进行分包。
• uni-app内支持对微信小程序、QQ小程序、百度小程序、支付宝小程序、抖音小程序(HBuilderX 3.0.3+)、快手小程序分包优化，即将静态资源或者js文件放入分包内不占用主包大小。详情请参考：关于分包优化的说明
• When vendor.js is too large, you can use runtime compression code
  • For the project created by HBuilderX, check Run-->Run to MiniApp Simulator-->Whether to compress the code at runtime
  • The project created by cli can add the parameter --minimize in package.json, example: "dev:mp-weixin": "cross-env NODE_ENV=development UNI_PLATFORM=mp-weixin vue-cli- service uni-build --watch --minimize"

Instructions:

假设支持分包的 uni-app 目录结构如下：

	
┌─pages
│  ├─index
│  │  └─index.vue
│  └─login
│     └─login.vue
├─pagesA
│  ├─static
│  └─list
│     └─list.vue
├─pagesB
│  ├─static
│  └─detail
│     └─detail.vue
├─static
├─main.js
├─App.vue
├─manifest.json
└─pages.json
	

You need to fill in pages.json

{
	"pages": [{
		"path": "pages/index/index",
		"style": { ...}
	}, {
		"path": "pages/login/login",
		"style": { ...}
	}],
	"subPackages": [{
		"root": "pagesA",
		"pages": [{
			"path": "list/list",

			"packages": ["__APP__"]
		},
		"pagesB/detail/detail": {
			"network": "all",
			"packages": ["pagesA"]
		}
	}
}

preloadRule

Subpackage preload configuration.

After the preloadRule is configured, when entering a certain page of the MiniApp, the framework will automatically pre-download the subpackages that may be required to improve the startup speed when entering subsequent subpackage pages

In preloadRule, key is the page path, and value is the pre-download configuration for entering this page. Each configuration has the following items:

Field	Type	Required	Default	Description
packages	StringArray	Yes	None	The root or name of the pre-download subpackage after entering the page. __APP__ represents the main package.
network	String	No	wifi	Pre-download under the specified network, optional values are: all (unlimited network), wifi (only pre-download under wifi)

App subcontracting also supports preloadRule, but network rules are invalid.

FAQ

• Q: Why is the MiniApp location permission description configured in pages.json, but cannot be compiled to the MiniApp side? After running, it keeps prompting that getLocation needs to be declared in app.json
• A: The permission description of the WeChat MiniApp is configured in the manifest, not in pages.json. For details, refer to the document: https://uniapp.dcloud.io/collocation/manifest?id=mp-weixin
