FaceBook第三方登录的接入封装

来源：互联网发布：增量内部收益率的算法编辑：程序博客网时间：2024/05/15 23:52

最近公司有一个app上线，并发布海外一个版本，对于登录的话就需要接入FaceBook ，Twitter，Instagram登录，首先向讲述一下FaceBook的登录接入，到FaceBook官网注册应用，主要有三个东西，app_id,这个是在代码中使用的配置的， shaHash值，这个后面讲，然后按照步骤将需要配置都配置一下就好了

第一步：

导入FaceBook的依赖包，FaceBook的依赖包是.arr库，我这里使用的是最新的facebook-android-sdk-4.18.0.aar，也可以直接放在libs库中使用，在app的build.gradle中配置一下内容即可：

repositories{
flatDir {
dirs 'libs'
}}

在依赖下面添加

compile(name: 'facebook-android-sdk-4.18.0', ext: 'aar')，

配置清单文件

<meta-data    android:name="com.facebook.sdk.ApplicationId"    android:value="@string/facebook_app_id"/><activity    tools:replace="android:theme"    android:name="com.facebook.FacebookActivity"    android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"    android:theme="@android:style/Theme.Translucent.NoTitleBar"    android:label="@string/app_name"    ></activity><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>

string.xml文件中的配置

<string name="facebook_app_id">237361146701659</string>  //这个是注册应用的appId<string name="fb_login_protocol_scheme">fb1630114020623262</string>

FaceBook的SDK就集成完毕了

第二步：登录的封装

public class FaceBookPlatform extends Platform {    private final CallbackManager callbackManager;    private final List<String> permissions;    private LoginManager loginManager;    private Activity context;    public boolean isFaceBook = false;    public FaceBookPlatform(final Activity context) {        super(context);        this.context = context;        callbackManager = CallbackManager.Factory.create();        getLoginManager().registerCallback(callbackManager, callback);        permissions = Arrays.asList("email", "user_likes",                "user_status", "user_photos", "user_birthday", "public_profile", "user_friends");    }    //注册回调    FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {        @Override        public void onSuccess(LoginResult loginResult) {            isFaceBook = false;            //Toast.makeText(context, "login successful", Toast.LENGTH_SHORT).show();            hideWait();            //获取用户信息            getLoginInfo(loginResult.getAccessToken());            AccessToken accessToken = loginResult.getAccessToken();            String userId = accessToken.getUserId();            String token = accessToken.getToken();            LogUtils.e("------" +"userId=" + userId);            LogUtils.e("------" +"token=" + token);           if (loginResult.getAccessToken() != null) {                LogUtils.e("-----  进入主页面" );               ********************处理登录成功后的逻辑******************************           }        }        @Override        public void onCancel() {            isFaceBook = false;            //取消登录            hideWait();            Toast.makeText(context, "login cancel", Toast.LENGTH_SHORT).show();        }        @Override        public void onError(FacebookException error) {            //登录出错            isFaceBook = false;            hideWait();            Toast.makeText(context, "something wrong", Toast.LENGTH_SHORT).show();            LogUtils.e("------" +"error.toString()=" + error.toString());        }    };    public void login(Activity activity) {        getLoginManager().logInWithReadPermissions(                activity, permissions);        isFaceBook = true;    }    /**     * 退出     */    public void logout() {        String logout = context.getResources().getString(                com.facebook.R.string.com_facebook_loginview_log_out_action);        String cancel = context.getResources().getString(                com.facebook.R.string.com_facebook_loginview_cancel_action);        String message;        Profile profile = Profile.getCurrentProfile();        if (profile != null && profile.getName() != null) {            message = String.format(                    context.getResources().getString(                            com.facebook.R.string.com_facebook_loginview_logged_in_as),                    profile.getName());        } else {            message = context.getResources().getString(                    com.facebook.R.string.com_facebook_loginview_logged_in_using_facebook);        }        AlertDialog.Builder builder = new AlertDialog.Builder(context);        builder.setMessage(message)                .setCancelable(true)                .setPositiveButton(logout, new DialogInterface.OnClickListener() {                    public void onClick(DialogInterface dialog, int which) {                        getLoginManager().logOut();                    }                })                .setNegativeButton(cancel, null);        builder.create().show();    }    private LoginManager getLoginManager() {        if (loginManager == null) {            loginManager = LoginManager.getInstance();        }        return loginManager;    }    public void getLoginInfo(AccessToken accessToken) {        GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {            @Override            public void onCompleted(JSONObject object, GraphResponse response) {                if (object != null) {                    String id = object.optString("id");                    String name = object.optString("name");                    String gender = object.optString("gender");                    String emali = object.optString("email");                    JSONObject object_pic = object.optJSONObject("picture");                    JSONObject object_data = object_pic.optJSONObject("data");                    String photo = object_data.optString("url");                    //获取地域信息                    String locale = object.optString("locale");                   // Toast.makeText(context, "" + object.toString(), Toast.LENGTH_SHORT).show();                }            }        });        Bundle parameters = new Bundle();        parameters.putString("fields", "id,name,link,gender,birthday,email,picture,locale," +                "updated_time,timezone,age_range,first_name,last_name");        request.setParameters(parameters);        request.executeAsync();    }    public CallbackManager getCallbackManager() {        return callbackManager;    }    /**     * 设置接口回调     *     */    private FacebookListener facebookListener;    public void setFacebookListener(FacebookListener facebookListener) {        this.facebookListener = facebookListener;    }    public interface FacebookListener {        void facebookLoginSuccess();        void facebookLoginFail();    }    public boolean getIssFaceBook() {        return isFaceBook;    }}

第三部：在activity设置点击事件的地方调用：

//创建登录平台的对象

faceBookPlatform = new FaceBookPlatform(this);

faceBookPlatform.login(this);

//重写onActivityResult方法

@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {    //faceBook的回调    if (faceBookPlatform.getIssFaceBook()) {        faceBookPlatform.getCallbackManager().onActivityResult(requestCode, resultCode, data);      super.onActivityResult(requestCode, resultCode, data);}

重要提示：需要的在application中初始化FaceBook的SDK

//初始化faceBook的SDKFacebookSdk.sdkInitialize( getApplicationContext());

注意点

并且当你在用手机测试的时候如果手机装了FaceBook是登录出错的，因为测试的时候是用的debug的apk,而在注册应用的时候核算shahash值的时候使用的release的apk，他们的hash值不一样，测试只能打开网页登录

另外还有一个类

public class Platform  {    public Context context;    private ProgressLoad load;    public Platform(Context context){        this.context = context;        init();    }    private void init(){        if(load == null){            load = new ProgressLoad(context);        }    }    public void showWait(){        load.show();    }    public void hideWait(){        load.dismiss();    }}

公司集成使用正常：如有问题请指出
