在facebook和firebase的官方网站上阅读了很多文档 我没有找到明确的答案
我的应用设计： 第一次登录Facebook和电子邮件 第二个屏幕 - 用户可以添加和删除文本的列表（如Todo列表）。
在firebase中“保存并授权”用户的正确方法 - 我的意思是选项 在数据库中，如“子”键和值，或用facebook用户详细信息创建新的firebase用户？
登录后如何将当前用户的访问权限设置为数据库中的列表？

import { Facebook } from 'ionic-native';
import * as firebase from 'firebase';
login() {
Facebook.login(['public_profile', 'email']).then((data) => {
//user logged in with Facebook successfully;
// create credential object using facebook access token
let credential = (<any> firebase.auth.FacebookAuthProvider).credential(data.authResponse.accessToken);
// try to authenticate firebase
firebase.auth().signInWithCredential(credential)
.then(function(user) {
// user logged into firebase successfully
})
.catch(function(error) {
})
}, (error) => {
// something went wrong
});
}

这里我在android中附加了一个示例facebook回调，其中包括带有firebase的facebook身份验证。
callbackManager = CallbackManager.Factory.create();
LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Firebase ref = new Firebase(AppConstants.FIREBASE_URL);//your firebase url
AccessToken token = loginResult.getAccessToken();
final ProgressDialog dialog = new ProgressDialog(LoginActivity.this);
dialog.setMessage("Logging....");
dialog.show();
Log.d("fbaccess", "Facebook AccessToken " + token.getToken());
ref.authWithOAuthToken("facebook", token.getToken(), new Firebase.AuthResultHandler() {
@Override
public void onAuthenticated(AuthData authData) {
Log.d("FBLOGIN", "The Facebook user is now authenticated with your Firebase app");
dialog.dismiss();
Toast.makeText(getApplicationContext(),"The Facebook user is now authenticated with your Firebase app",Toast.LENGTH_LONG).show();
//add your intent
}
@Override
public void onAuthenticationError(FirebaseError firebaseError) {
// there was an error
Log.d("FBLOGIN", "Tthere was an error with your Firebase app");
}
});
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException error) {
}
});

在这里，我尝试使用firebase身份验证解决facebook集成问题。
首先，您需要在Facebook开发人员中创建项目并获取facebook密钥，并在firebase控制台中创建项目并获取 google-services.json 文件并放入 app 项目结构。
在build.gradle（app level）中为facebook sdk和firebase身份验证添加依赖项。
compile 'com.facebook.android:facebook-android-sdk:4.+'
compile 'com.google.firebase:firebase-auth:11.6.2'
compile 'com.google.android.gms:play-services-auth:11.6.2'
apply plugin: 'com.google.gms.google-services'
现在在build.gradle（proj level）中添加google play服务。
classpath 'com.google.gms:google-services:3.1.0'
在AndroidManifest.xml中添加facebook密钥
<uses-permission android:name="android.permission.INTERNET" />
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="@string/facebook_app_id"/>
<activity android:name="com.facebook.FacebookActivity"
android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="@string/app_name" />
<强> activity_login.xml
<Button
android:id="@+id/btnSignInFaceBook"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<强> LoginActivity.class
public class LoginActivity extends AppCompactActivity{
Button faceBookBtn;
String fbId = "",fbemail="";
private FirebaseAuth mAuth;
//Facebook Declaration
CallbackManager callbackManager;
LoginManager loginManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
FacebookSdk.sdkInitialize(getApplicationContext());
callbackManager = CallbackManager.Factory.create();
initUI();
}
private void initUI(){
faceBookBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
faceBookLogin();
}
});
}
private void faceBookLogin() {
loginManager = LoginManager.getInstance();
loginManager.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(final LoginResult loginResult) {
Log.d(TAG, "facebook:onSuccess:" + loginResult);
if (AccessToken.getCurrentAccessToken() != null) {
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
if (object != null) {
try {
AppEventsLogger logger = AppEventsLogger.newLogger(LoginActivity.this);
logger.logEvent("Facebook login suceess");
handleFacebookAccessToken(loginResult.getAccessToken());
} catch (Exception e) {
e.printStackTrace();
}
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday, about");
request.setParameters(parameters);
request.executeAsync();
}
}
@Override
public void onCancel() {
Log.d(TAG, "facebook:onCancel");
}
@Override
public void onError(FacebookException error) {
Log.d(TAG, "facebook:onError", error);
}
});
loginManager.logInWithReadPermissions(LoginActivity.this, Arrays.asList("email", "public_profile"));
}
private void handleFacebookAccessToken(AccessToken token) {
Log.d(TAG, "handleFacebookAccessToken:" + token);
mAuth = FirebaseAuth.getInstance();
AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
// Sign in success, update UI with the signed-in user's information
Log.d(TAG, "signInWithCredential:success");
FirebaseUser user = mAuth.getCurrentUser();
if (user != null) {
Log.i(TAG, "email" + user.getEmail());
}
} else {
// If sign in fails, display a message to the user.
Log.w(TAG, "signInWithCredential:failure", task.getException());
}
}
});
}
}
退出。
FirebaseAuth.getInstance().signOut();
希望这会对你有所帮助： - ）
