快速集成Twitter、Facebook登录并获取用户信息

最近公司做一个国外的项目，需要集成Twitter、Facebook登录，所以在此记录下集成的过程。由于Twitter、Facebook是国外软件，需要翻墙，这个自行解决。

Twitter登录的集成

首先需要在https://apps.twitter.com/这个网站创建你的APP，创建完之后可以获取到Consumer Key、Consumer Secret 。如下图：

集成步骤

1.在gradle中集成SDK

compile 'com.twitter.sdk.android:twitter-core:3.1.1'

这里是登录所需的SDK，需要用其他功能可以查看官方的文档https://github.com/twitter/twitter-kit-android/wiki

2.在Application中用如下代码初始化SDK

@Overridepublic void onCreate() {super.onCreate();//Twitter初始化Twitter.initialize(getApplicationContext());}

3.添加你的Consumer Key、Consumer Secret到资源文件中

 <string name="com.twitter.sdk.android.CONSUMER_KEY">你的Consumer Key</string>
<string name="com.twitter.sdk.android.CONSUMER_SECRET">Consumer Secret</string>

到这一步前期工作基本完成，接下来编写代码了。代码我这里已经封装好了。

/***先写个接口，Facebook集成也要用* Created by 刘信 on 2018/3/9.*/public interface Platform {//登录void  Login();//登出void  loginOut();//是否已经登录boolean isLogin();//监听回调void  setPlatformListener(PlatformListener platformListener);//需要在Activity中回调这个void onActivityResult(int requestCode, int resultCode, Intent data);}

/***回调监听* Created by 刘信 on 2018/3/9.*/public interface PlatformListener {//登录成功 hasUserMessage 是否获取到用户信息了void onSuccess(boolean hasUserMessage,UserBean userBean);//登录取消void  onCancel();//登录失败void onError(Throwable throwable,String errorMsg);
}

Twitter的全部逻辑功能在下面这个类中：

/*** Created by 刘信 on 2018/3/9.*/public class Twitter implements Platform {public static final String NAME = Twitter.class.getSimpleName();PlatformListener platformListener;volatile TwitterAuthClient authClient;WeakReference<Activity> activityRef;Callback<TwitterSession> callback;public Twitter(Activity activity) {activityRef = new WeakReference<Activity>(activity);callback = new Callback<TwitterSession>() {@Overridepublic void success(Result<TwitterSession> result) {Logger.i(NAME, Thread.currentThread().getName());Logger.i(NAME, result.data.getUserName());getTwitterInfo();}@Overridepublic void failure(TwitterException exception) {Logger.i(NAME, exception.getMessage());if(platformListener!=null){platformListener.onError(exception,exception.getMessage());}}};}@Overridepublic void Login() {Activity activity = activityRef.get();if (activity == null) {Logger.e(NAME, "activiy is null,is Activity destroyed?");return;}getTwitterAuthClient().authorize(activity, callback);}@Overridepublic void loginOut() {try {SessionManager<TwitterSession> sessionManager = TwitterCore.getInstance().getSessionManager();if (sessionManager != null) {sessionManager.clearActiveSession();}} catch (Exception e) {e.printStackTrace();}}@Overridepublic boolean isLogin() {return TwitterCore.getInstance().getSessionManager().getActiveSession()!=null;}@Overridepublic void setPlatformListener(PlatformListener platformListener) {this.platformListener = platformListener;}@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {if (requestCode == getTwitterAuthClient().getRequestCode()) {getTwitterAuthClient().onActivityResult(requestCode, resultCode, data);}}private TwitterAuthClient getTwitterAuthClient() {if (authClient == null) {synchronized (Twitter.class) {if (authClient == null) {authClient = new TwitterAuthClient();}}}return authClient;}/***获取用户信息接口文档https://developer.twitter.com/en/docs/accounts-and-users/follow-search-get-    users/api-reference/get-users-show*获取用户信息*/private void getTwitterInfo() {TwitterApiClient twitterApiClient = TwitterCore.getInstance().getApiClient();Call<User> call=twitterApiClient.getAccountService().verifyCredentials(false,true,false);call.enqueue(new Callback<User>() {@Overridepublic void success(Result<User> result) {//返回的照片48*48 好小 性别没返回啊if(platformListener!=null) {if (result.response.isSuccessful()) {User user = result.data;if (user != null) {UserBean userBean = new UserBean();userBean.setName(user.name);userBean.setAvatar(user.profileImageUrl);platformListener.onSuccess(true,userBean);}else {platformListener.onSuccess(false,null);}}else {platformListener.onSuccess(false,null);}}}@Overridepublic void failure(TwitterException exception) {Logger.i(NAME,exception.getMessage());if(platformListener!=null){platformListener.onSuccess(false,null);}}});}}

接下来在Activity中调用即可，如下面代码

   @Overrideprotected void click(View view) {switch (view.getId()) {case R.id.ib_facebook:thirdLogin(FaceBook.NAME);break;case R.id.ib_twitter:thirdLogin(Twitter.NAME);break;}}
private void thirdLogin(String name){platform=LoginSDk.getPlatFrom(this,name);if(!platform.isLogin()) {platform.setPlatformListener(new PlatformListener() {@Overridepublic void onSuccess(boolean hasUserMessage, UserBean userBean) {//登录成功回调}@Overridepublic void onCancel() {//登录取消}@Overridepublic void onError(Throwable throwable, String errorMsg) {//登录失败}});platform.Login();}else {platform.loginOut();}}//需要重写这个@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {if(platform!=null) {platform.onActivityResult(requestCode, resultCode, data);}super.onActivityResult(requestCode, resultCode, data);}

Facebook的集成

facebook开发者网站https://developers.facebook.com/，首先你需要在这个网址按照它的提示创建应用。

集成步骤

1.添加gradle依赖

 //facebookcompile 'com.facebook.android:facebook-login:4.31.0'

2.编辑资源文件和配置清单

在string.xml中添加

 <string name=你的AppId</string><string name="fb_login_protocol_scheme">你的登录协议</string>

在配置清单添加

<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" /><activity
        android:name="com.facebook.CustomTabActivity"android:exported="true"><intent-filter><action android:name="android.intent.action.VIEW" /><category android:name="android.intent.category.DEFAULT" /><category android:name="android.intent.category.BROWSABLE" /><data android:scheme="@string/fb_login_protocol_scheme" /></intent-filter></activity>

到这一步前期工作准备完成了，现在编写登录逻辑代码

/*** Created by 刘信 on 2018/3/9.*/public class FaceBook implements Platform {public static final String NAME = FaceBook.class.getSimpleName();CallbackManager callbackManager;PlatformListener platformListener;WeakReference<Activity> activityRef;public FaceBook(Activity activity) {activityRef = new WeakReference<Activity>(activity);callbackManager = CallbackManager.Factory.create();LoginManager.getInstance().registerCallback(callbackManager,new FacebookCallback<LoginResult>() {@Overridepublic void onSuccess(LoginResult loginResult) {// App codeLogger.i(NAME, Thread.currentThread().getName());Logger.i(NAME, loginResult.getAccessToken().getUserId());getUserInfo(loginResult.getAccessToken());}@Overridepublic void onCancel() {// App codeif(platformListener!=null){platformListener.onCancel();}Log.i(NAME, "取消登录");}@Overridepublic void onError(FacebookException exception) {// App codeLogger.i(NAME, "登录失败");if(platformListener!=null){platformListener.onError(exception,exception.getMessage());}}});}@Overridepublic void Login() {Activity activity = activityRef.get();if (activity == null) {Logger.e(NAME, "activiy is null,is Activity destroyed?");return;}LoginManager.getInstance().logInWithReadPermissions(activity, Arrays.asList("public_profile"));}@Overridepublic void loginOut() {LoginManager.getInstance().logOut();}@Overridepublic boolean isLogin() {return AccessToken.getCurrentAccessToken() != null;}@Overridepublic void setPlatformListener(PlatformListener platformListener) {this.platformListener = platformListener;}@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {callbackManager.onActivityResult(requestCode, resultCode, data);}private void getUserInfo(AccessToken accessToken){Bundle parameters = new Bundle();parameters.putString("fields", "id,name,gender,picture");GraphRequest graphRequest= GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {@Overridepublic void onCompleted(JSONObject object, GraphResponse response) {//这里获取的头像是50*50try {if (platformListener != null) {if (object != null) {String name = object.optString("name");String gender = object.optString("gender");String picture="";JSONObject jsonObject = object.optJSONObject("picture");if(jsonObject!=null){JSONObject data=jsonObject.optJSONObject("data");if(data!=null){picture=data.optString("url");}}UserBean userBean = new UserBean();userBean.setName(name);userBean.setSex(gender);userBean.setAvatar(picture);platformListener.onSuccess(true, userBean);}else {platformListener.onSuccess(false, null);}}}catch (Exception e){if(platformListener!=null) {platformListener.onSuccess(false, null);}e.printStackTrace();}}});graphRequest.setParameters(parameters);graphRequest.executeAsync();}}

在Activity调用方式如上面的Twitter，这里就不在讲了。最后这里贴下LoginSDK的代码，很简单


public class LoginSDk {@NonNullpublic static Platform getPlatFrom(Activity activity,String platform){if(FaceBook.NAME.equals(platform)){return  new FaceBook(activity);}else if(Twitter.NAME.equals(platform)){return new Twitter(activity);}return null;}
}
