web-view
Feature description:A container that hosts the H5 pages. It will automatically fill the mini program page.
Parameter and description:
|
src | string | - | H5 page URL. Configure the H5 page domain in the mini program management backend. |
bindmessage | eventhandler | - | Triggered when the H5 page uses the wx.miniProgram.postMessage to send a message to the mini program. This occurs during back navigation, component destruction, or sharing. e.detail = { data }, where data is an array of parameters from multiple postMessage calls. |
bindload | eventhandler | - | Triggered when the H5 page is loaded successfully. e.detail = { src } |
binderror | eventhandler | - | Triggered when the H5 page fails to load. e.detail = { url, fullUrl }, where fullUrl is the complete URL that failed to load. |
bindevent | eventhandler | - | Triggered when the H5 page uses the wx.miniProgram.sendWebviewEvent to send a message to the mini program. e.detail = { data }, where data is the parameter from sendWebviewEvent. |
Notes:
The iframe domain within the H5 page must also be configured as the allowed domain.
In the developer tools, click the debug button on the <web-view> component for debugging.
Each H5 page can only have one <web-view>. It will automatically fill the entire page and cover other components.
Only the JSSDK API can be used to enable the communication between the H5 page embedded in the <web-view> component and the mini program.
The priority of the navigation bar title for the page containing the <web-view> component:<title></title>
(H5 page) > wx.navigationBarTitleText
(miniprogram) > navigationBarTitleText
(page.json)> navigationBarTitleText
(app.json)
Authorization
Some APIs require user consent before they can be called. We divide these APIs into multiple scopes according to their usage. When the user provides authorization to a scope, all the APIs in the scope can be called directly.
When such APIs are called:
If the user has neither accepted nor declined this permission, a pop-up will appear asking for their consent. The API can only be called if the user agrees.
If the user has already granted permission, the APIs can be called directly.
If the user has previously denied permission, no pop-up will appear, and the API will immediately trigger the fail callback.Developers should ensure their applications handle scenarios where the user has denied permission.
To obtain user authorization status
Developers can get the user's current authorization status using wx.getSetting.
To open the settings page
Users can manage the authorization status for the mini program on the mini program settings page through <b>Settings</b> in the upper-right corner.
Developers can call wx.openSetting to open the settings page and guide users to enable the authorization.
To initiate an authorization request in advance
Developers can use wx.authorize to initiate authorization requests to users before calling the APIs that require authorization.

Authorization validity
The user’s approval or rejection for the authorization request is recorded locally on the client until the mini program is deleted.
Best practices
Initiates an authorization request to the user when you need to call the API. Clearly explain the reason for calling in the request.
