React Native Permissions不打印状态

Question

我正在使用React Native版本42并询问如下权限.但在允许或拒绝权限后,我没有在控制台中看到状态.根据文档https://facebook.github.io/react-native/docs/permissionsandroid.html,他们说我们可以在控制台中看到状态.任何人都可以帮助我做错了什么.我想打印已授予的状态但该行本身未被调用.

componentDidMount() {       
this.requestPermissions();
}

async requestPermissions() {

    try {  
        const granted = await PermissionsAndroid.requestMultiple([PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION, PermissionsAndroid.PERMISSIONS.READ_PHONE_STATE, PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE])
        console.log("permissions status: " +JSON.stringify(granted));
    } catch (err) {
        console.warn(err)
    }
}

PermissionAndroid.requestMultiple返回具有权限状态的promise.试试这样吧

PermissionsAndroid.requestMultiple([PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION, PermissionsAndroid.PERMISSIONS.READ_PHONE_STATE, PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE]).then((result) => {
  console.log('result', result);
})
