Question

我们正在为其中一个项目实施Firebase Facebook身份验证。我们也遵循了文档中提到的步骤。

以下是oAuth网址：

import React, { Component } from 'react';
import ScrollableTabView, {ScrollableTabBar, } from 'react-native-scrollable-tab-view';
import { GiftedChat } from 'react-native-gifted-chat';

  constructor(props){
    super(props);
    this.state = {
      messages: []
    }
    this.onSend = this.onSend.bind(this);
  }
  componentWillMount() {
    this.setState({
      messages: [

          text: 'Hello developer',
          createdAt: new Date(Date.UTC(2016, 7, 30, 17, 20, 0)),
          user: {
            _id: 2,
            name: 'React Native',
            avatar: 'https://facebook.github.io/react/img/logo_og.png',

        },
      ],
    });
  }
  onSend(messages = []) {
    this.setState((previousState) => {
      return {
        messages: GiftedChat.append(previousState.messages, messages),
      };
    });
  }
  render() {
      return (
        <View>
             <ScrollableTabView
                   style={{marginTop: 20, }}
                   initialPage={0}
                   renderTabBar={() => <ScrollableTabBar />}
                 >
                <View tabLabel='Conversation'>
                   <GiftedChat
                     messages={this.state.messages}
                     onSend={this.onSend}
                     user={{
                       _id: 1,
                     }}
                   />
                </View>
             </ScrollableTabView>
        </View>
      );
  }
}
const styles = StyleSheet.create({
});

AppRegistry.registerComponent('whistle', () => whistle);

我也添加了其余的凭据（例如https://<APP_NAME>.firebaseapp.com/__/auth/handler＆amp; APP_ID），而且应用程序处于开发阶段，我已将APP_SECRET添加为以及Facebook门户网站和Firebase门户网站。

key hash初始流程效果很好，但当用户Login授予访问权限时，confirm注册表根本不响应callback也没有negative确认。

这是我们的代码：

如果我们错过了什么，请告诉我们。我假设private static final String TAG = "FacebookLogin"; private CallbackManager mCallbackManager; private FirebaseAuth mAuth; private FirebaseAuth.AuthStateListener mAuthListener; mAuth = FirebaseAuth.getInstance(); mAuthListener = new FirebaseAuth.AuthStateListener() { @Override public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) { FirebaseUser user = firebaseAuth.getCurrentUser(); if (user != null) { // User is signed in Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid()); } else { // User is signed out Log.d(TAG, "onAuthStateChanged:signed_out"); } // ... } }; // Initialize Facebook Login button mCallbackManager = CallbackManager.Factory.create(); LoginButton loginButton = (LoginButton) findViewById(R.id.button_facebook_login); loginButton.setReadPermissions("email", "public_profile"); loginButton.registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() { @Override public void onSuccess(LoginResult loginResult) { Log.d(TAG, "facebook:onSuccess:" + loginResult); handleFacebookAccessToken(loginResult.getAccessToken()); } @Override public void onCancel() { Log.d(TAG, "facebook:onCancel"); // ... } @Override public void onError(FacebookException error) { Log.d(TAG, "facebook:onError"+ error); // ... } }); @Override public void onStart() { super.onStart(); mAuth.addAuthStateListener(mAuthListener); } @Override public void onStop() { super.onStop(); if (mAuthListener != null) { mAuth.removeAuthStateListener(mAuthListener); } } private void handleFacebookAccessToken(AccessToken token) { Log.d(TAG, "handleFacebookAccessToken:" + token); AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken()); mAuth.signInWithCredential(credential) .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { @Override public void onComplete(@NonNull Task<AuthResult> task) { Log.d(TAG, "signInWithCredential:onComplete:" + task.isSuccessful()); // If sign in fails, display a message to the user. If sign in succeeds // the auth state listener will be notified and logic to handle the // signed in user can be handled in the listener. if (!task.isSuccessful()) { Log.w(TAG, "signInWithCredential", task.getException()); Toast.makeText(FacebookLoginActivity.this, "Authentication failed.", Toast.LENGTH_SHORT).show(); } // ... } }); }网址有问题，因此有关此内容的更多信息会有所帮助，因为Firebase文档没有明确说明如何构建该网址。提前谢谢。

你添加了

吗？

mCallbackManager.onActivityResult（requestCode，resultCode，data）;

你的onActivityResult块中的

？

修改

参考Firebase https://github.com/firebase/quickstart-android/blob/master/auth/app/src/minSdkJellybean/java/com/google/firebase/quickstart/auth/FacebookLoginActivity.java中的示例，

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    mCallbackManager.onActivityResult(requestCode, resultCode, data);
}

如果没有添加，则不会回调。
