第三方登录google+facebook

之前网上看到的关于google和facebook登录接入的介绍的很详细，却也比较复杂，今天我把我总结的贴出来，希望对大家有所帮助

一  Facebook登录

1.在facebook平台获取应用编号这个应该都会了，我直接该出API地址

https://developers.facebook.com/docs/android/getting-started

2 密钥散列的获取方式

hash key:       
在你的Java jdk地址 目录下shift+鼠标右键打开cmd：
keytool -exportcert -alias xn -keystore "你的keystore地址" | "你的openssl地址" sha1 -binary | "你的openssl地址" base64

3 AndroidManifest.xml

你的应用编号
	fb你的应用编号



        

        
            
                

                
                

                
            
        

4 封装代码

​
public class Facebook {
	public CallbackManager callbackManager = CallbackManager.Factory.create();
	
	private Activity activity;
	private List permissions = Collections.emptyList();

	public Facebook(final Activity activity) {
		this.activity = activity;

		LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback() {
			@Override
			public void onSuccess(LoginResult loginResult) {
				// login success
				if (loginResult == null) {
					return;
				}
				AccessToken accessToken = loginResult.getAccessToken();
				String userId = accessToken.getUserId();
				//String token = accessToken.getToken();
				Log.e("res", "facebook_res:" + accessToken.toString());
				
				// 拿到userId和token，传给服务器校验

			}

			@Override
			public void onCancel() {
				WDQCPlatform.getInstance().doLogin(StatusCode.FAIL, null);
			}

			@Override
			public void onError(FacebookException error) {
				WDQCPlatform.getInstance().doLogin(StatusCode.FAIL, null);
			}
		});

		permissions = Arrays.asList("email", "public_profile");
	}

	public void login() {
		LoginManager.getInstance().logInWithReadPermissions(activity, permissions);
	}

	public void logout() {
		LoginManager.getInstance().logOut();
	}

}

​

5 执行代码

​
private Facebook faceBook;

private void login(){
    if(faceBook == null){
		faceBook = new Facebook(activity, this);				
	}
	faceBook.login();
}

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

		if (faceBook != null) {
			faceBook.callbackManager.onActivityResult(requestCode, resultCode, data);
		}

	}

private void logout(){
    if (faceBook != null) {
		faceBook.logout();
	}
}

​

二 google登录

1在google平台创建应用并下载google-services.json，我直接该出API地址

https://console.developers.google.com/apis/credentials

还有创建应用和下载google-services.json的地址

https://console.firebase.google.com/?hl=zh-cn

这个下载完就可以了

2 AndroidManifest.xml

8298000



        

3 封装代码

public class Google {
	private FragmentActivity activity;
	public GoogleSignInOptions gso;
	public GoogleApiClient mGoogleApiClient;

	public Google(FragmentActivity activity) {
		this.activity = activity;

		gso = new GoogleSignInOptions
				.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
				.requestEmail()
				.requestId()
				//.requestIdToken("504221091116-k75t0rf6forvi2e554no78f9s8dkf7uh.apps.googleusercontent.com")
				.requestProfile()
				.build();

		mGoogleApiClient = new GoogleApiClient
				.Builder(activity)
				.enableAutoManage(activity, new OnConnectionFailedListener() {
					
					@Override
					public void onConnectionFailed(ConnectionResult result) {
						// TODO Auto-generated method stub
						
					}
				})
				.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
				.build();
	}

	public void login() {
		Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
		activity.startActivityForResult(signInIntent, Constant.RC_GOOGLE);
	}

	public void logout() {
		Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(new ResultCallback() {
			@Override
			public void onResult(Status status) {
				// TODO Auto-generated method stub
				if (status.isSuccess()) {

				} else {

				}
			}
		});
	}

	public String handleSignInResult(GoogleSignInResult result) {
		String res = "";
		if (result.isSuccess()) {
			GoogleSignInAccount acct = result.getSignInAccount();
			
			res = "登录成功--" + "用户名为：" + acct.getDisplayName() + "  邮箱为：" + acct.getEmail() + " token为：" + acct.getIdToken()
					+ " 头像地址为：" + acct.getPhotoUrl() + " Id为：" + acct.getId() + " GrantedScopes为："
					+ acct.getGrantedScopes();
			
			Log.e("res", "google_res:" + res);
			
			// 拿到userId和token，传给服务器校验

		return res;
	}

}

4 执行代码

private Google googleLogin;

private void login(){
    if(googleLogin == null){
		googleLogin = new Google(activity, this);
	}				
	googleLogin.login();
}

private void logout(){
    if (googleLogin != null) {
		googleLogin.logout();
	}
}

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

		if (requestCode == Constant.RC_GOOGLE && googleLogin != null) {
			GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
			googleLogin.handleSignInResult(result);
		}

}

好，到此结束！！！
