此环境中不支持FIrebase Google身份验证操作

问题描述

我正在开发离子和firebase项目，登录页面使用谷歌登录。

  var provider = new firebase.auth.GoogleAuthProvider（）; 
 firebase.auth（）。signInWithRedirect（provider）.then（function（result）{
 var token = result.credential.accessToken; 
 //登录的用户信息
 var user = result.user; 
 $ state.go（'app.homepage'）; 
}）。catch（function（error）{
}）; 
 
 firebase.auth（）。getRedirectResult（）。then（function（result）{
 if（result.credential）{
 var token = result.credential.accessToken; 
} 
 //登录的用户信息
 var user = result.user; 
}）。catch（function（error）{
}）; 
  

当我在浏览器中运行它时工作正常，但是当我在android设备上运行它时我在这个环境中获得了auth / operation-not-supported。
应用程序正在location.protocol上运行。
我研究了一下，但找不到确切的答案。什么可能是错误的？

解决方案

弹出和重定向操作当前不支持在Ionic / Cordova环境中。作为后备，您可以使用oauth cordova插件获取Google / Facebook OAuth访问令牌，然后通过signInWithCredential登录用户。检查此线程的更多信息：

auth.signInWithCredential（firebase.auth.FacebookAuthProvider.credential（fbAccessToken））;

I am working on ionic and firebase project, made a login page to sign in with google. I am using this Below.

        var provider = new firebase.auth.GoogleAuthProvider();
        firebase.auth().signInWithRedirect(provider).then(function (result) {
            var token = result.credential.accessToken;
            // The signed-in user info.
            var user = result.user;
            $state.go('app.homepage');
        }).catch(function (error) {
        });

        firebase.auth().getRedirectResult().then(function (result) {
            if (result.credential) {
                var token = result.credential.accessToken;
            }
            // The signed-in user info.
            var user = result.user;
        }).catch(function (error) {
        });

When I run it in the browser it is working fine, but when I run it in android device I am getting auth/operation-not-supported-in-this environment.The application is running on "location.protocol".I researched a bit but could not find an exact answer. What could be wrong ?

解决方案

popup and redirect operations are not currently supported in Ionic/Cordova environment. As a a fallback you can you an oauth cordova plugin to obtain a google/facebook OAuth access token and then sign in the user via signInWithCredential. Check this thread for more on this:

auth.signInWithCredential(firebase.auth.FacebookAuthProvider.credential(fbAccessToken));
