Firebase Google Auth无法使用Safari

Question

我有一个功能：

function loginWithGoogle () {
        firebase.auth().signInWithRedirect(provider);
}


firebase.auth().getRedirectResult().then(function(result) {
      if (result.credential) {
        // This gives you a Google Access Token. You can use it to access the Google API.
        var token = result.credential.accessToken;
      }          
      var user = result.user; // The signed-in user info.
    }).catch(function(error) {
      // Handle Errors here.
      var errorCode = error.code;
      var errorMessage = error.message;
      var email = error.email; // The email of the user's account used.          
      var credential = error.credential; // The firebase.auth.AuthCredential type that was used.
  });

当用户点击登录按钮时运行。但是，这似乎不适用于Safari（使用移动模拟器和我的桌面）。代码在Chrome上正常运行。我还需要添加其他内容以确保支持Safari吗？谢谢！
