How uniapp handles authorization

With the rapid development of the mobile Internet, there are more and more various APPs, and authorizations involving user information are becoming more and more frequent. As front-end developers, we need to learn how to handle authorization, especially when using a cross-platform development framework like uniapp, how to better handle authorization issues?

1. Understand the types of authorization

Before processing authorization, we need to understand the types of authorization. Usually, authorization is divided into two categories:

a. User authorization: that is, authorization initiated by the user, such as authorizing WeChat login, authorizing obtaining location information, etc.

b. System authorization: Authorization actively initiated by the operating system, such as camera permissions, storage permissions, etc.

2. Use uniapp’s built-in API

uniapp has some built-in APIs for handling authorization. For example:

a.uni.authorize interface: used to request user authorization, and can request permissions such as user information, positioning information, camera, and recording.

b.uni.getSetting interface: Get the user's authorized permission list. You can also apply for authorization in this interface.

c.uni.request interface: used to initiate network requests. When using uni.request to initiate a request, if user authorization needs to be obtained dynamically, an authorization prompt will be prompted.

3. Authorization callback function

In using the above interface, we need to use the authorization callback function, such as:

uni.authorize({
    scope: 'scope.record',
    success() {
        console.log('授权成功')
    },
    fail() {
        console.log('授权失败')
    }
})

In the above code, if the user chooses to allow authorization, Then print "Authorization Successful" in the callback function, otherwise print "Authorization Failed".

4. Optimize user experience

When dealing with authorization, we need to consider user experience issues. Some authorization operations require manual confirmation by users, so we need to optimize the user experience and reduce unnecessary authorization processes.

a. When the APP starts, ask the user whether to allow authorization. If allowed, authorize directly, otherwise enter the authorization boot process.

b. Avoid too many authorization operations. If an APP requires multiple permissions, you can try to classify the permissions for authorization to reduce the difficulty of authorization for users.

c. Try to use anti-blocking strategies. Limit the scope of authorization and avoid frequent authorization requests.

In short, properly handling authorization issues is crucial to improving user experience and APP usage. When developing using uniapp, we need to understand authorization types, use built-in APIs, handle authorization callback functions, and optimize user experience to better handle authorization issues.
