Mini program permissions - Mobile Platform as a Service - Alibaba Cloud Documentation Center

Some special APIs of mini programs, such as location, camera, and photo album, usually prompt the user for authorization. These APIs can be executed only after the user allows it.

The mini program container allows the following extensions for API calls:

Custom text prompts, the access party can control the text and display style.
Allows the access party to read and write permissions configuration.

Note

This extended configuration is available only when mini program permission control is enabled in the background.

Permission configuration

The mini programs' default key and the corresponding API are shown in the following table:

Permission	key	API
camera	camera	scan, chooseImage, chooseVideo
photo album	album	saveImage, saveVideosToPhotosAlbum
location	location	getLocation, getCurrentLocation
microphone	audioRecord	startAudioRecord, stopAudioRecord, cancelAudioRecord

You can obtain a dictionary of permissions that the current mini program has requested:

Custom display

mPaaS supports to customize the dialog box of permissions.

The steps are as follows:

After the container is initialized, specify the delegate in the custom permissions dialog box.

 - (void)application:(UIApplication *)application afterDidFinishLaunchingWithOptions:(NSDictionary *)launchOptions
 {
    ...

     // Manage mini program API permissions.
    [TAAuthorizeStorageManager shareInstance].authorizeAlertDelegate = self;

    ...
 }

The method of implementing a custom permissions dialog box.

#pragma mark mini program API permission control
 - (void)showAlertWithTitle:(NSString *)title appName:(NSString *)appName storageKey:(NSString *)storageKey callback:(void (^)(NSInteger index))callback
 {
     if ([title length] > 0) {
         UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                         message:nil
                                                        delegate:self
                                               cancelButtonTitle:@"Cancel"
                                               otherButtonTitles:@"OK", nil];

         self.callback = callback;
         [alert show];
     }

 }

 - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
 {
     if (self.callback) {
         if (buttonIndex == alertView.cancelButtonIndex) {
           // Authorization is allowed for the user. The callback parameter is 0.
           self.callback(0);
         }else{
           // Authorization is allowed for the user. The callback parameter is 1.
           self.callback(1);
         }
     }
