[英]Ionic - How to request permission again after user rejected once?
目前,如果用戶沒有拒絕授予權限,我可以使用以下代碼請求麥克風權限:
permission = await this.diagnostic.isMicrophoneAuthorized();
if (!permission) {
permission = await this.diagnostic.requestMicrophoneAuthorization()
.then(async () => {
console.log('this.diagnostic.requestMicrophoneAuthorization succeed.');
return await this.diagnostic.isMicrophoneAuthorized();
})
.catch((err) => {
console.error('this.diagnostic.requestMicrophoneAuthorization failed, error: ', err);
return false;
})
}
但是一旦他們拒絕請求, requestMicrophoneAuthorization
仍然會被觸發,但不會彈出對話框,結果總是返回 false。
有沒有辦法用 Ionic 3 再次請求授權?
為此,您需要使用cordova-diagnostic-plugin
檢查當前的麥克風授權狀態,如果被拒絕則再次請求授權。
import { Diagnostic } from '@ionic-native/diagnostic/ngx';
constructor(private diagnostic: Diagnostic) {}
async requestMicrophoneAuthorization() {
// Check the current microphone authorization status
let authorizationStatus = await this.diagnostic.getMicrophoneAuthorizationStatus();
if (authorizationStatus === this.diagnostic.permissionStatus.DENIED_ALWAYS) {
// If the authorization has been denied always, we need to ask the user to grant
// microphone permission again.
try {
// Request microphone authorization
authorizationStatus = await this.diagnostic.requestMicrophoneAuthorization();
console.log('Microphone authorization status: ', authorizationStatus);
} catch (error) {
console.error('Error requesting microphone authorization: ', error);
}
}
}
