• Android中使用Kotlin实现Google、FaceBook、Twitter登录的封装


    最近由于项目做国际化,所以需要接入Google、FaceBook、Twitter等各种第三方登录的Api,于是查找官网资料,申请各种key和密钥,最后成功完成了这三个第三方登录Api的功能,但是由于很多地方需要调用,前期做得很粗糙,发现调用很麻烦,于是做了一次封装,总结一下,关于资料的申请这里就不说了,本博客采用的是Kotlin代码,不熟悉Kotlin的同学可以学习一下,直接上封装的代码:

    一、接入Google、Facebook、Twitter之前需要安装Google服务,所以首先需要判断用户是否安装Google服务插件,这里说特别说明一下,一定要安装官网的正版Google服务插件,要不然会出现各种问题,这里就不展开了.检测用户是否安装Google服务的方法如下:


     

    /**

    * 检查用户是否安装Google Play 服务

    */

    open fun onCheckGooglePlayService(activity:Activity,code:Int){

    // 验证是否已在此设备上安装并启用Google Play服务,以及此设备上安装的旧版本是否为此客户端所需的版本

    GoogleApiAvailability.getInstance().makeGooglePlayServicesAvailable(activity)

    /**

    * 通过isUserResolvableError来确定是否可以通过用户操作解决错误

    */

    if (GoogleApiAvailability.getInstance().isUserResolvableError(code)) {

        GoogleApiAvailability.getInstance().getErrorDialog(activity, code, 200).show()

    }

    }

    fun checkGooglePlayServiceExist(activity: Activity): Int {

        return GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(activity)

    }

    二.Google登录工具类的封装:


     

    /**

    * @author: njb

    * @date: 2021/5/8 14:37

    * @desc: Google登录工具类

    */

    open class GoogleLoginUtils(private val activity: Activity, var listener: GoogleSignListener) {

        var requestCode = 10

        private var mGoogleSignInClient: GoogleSignInClient? = null

        private var googleSignListener: GoogleSignListener? = null

        init {

            //初始化谷歌登录服务

            val gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)

                    .requestEmail()

                    .build()

            mGoogleSignInClient = GoogleSignIn.getClient(activity, gso)

        }

        /**

        * 登录

        */

        open fun signIn() {

            val signInIntent: Intent = mGoogleSignInClient!!.signInIntent

            activity.startActivityForResult(signInIntent, requestCode)

        }

        /**

        * 退出登录

        */

        open fun signOut() {

        }

        fun handleSignInResult(completedTask: Task<GoogleSignInAccount>) {

            try {

                val account: GoogleSignInAccount? = completedTask.getResult(ApiException::class.java)

                val status: Task<GoogleSignInAccount> = completedTask

                if (status.isSuccessful) {

                    if (account != null) {

                        //ToastUtils.showShort(activity.getString(R.string.login_success))

                        googleSignListener?.googleLoginSuccess(account)

                        LogUtils.d("account" + account?.account)

                    } else {

                        googleSignListener?.googleLoginFail(activity.getString(R.string.login_failed))

                    }

                }

            } catch (e: ApiException) {

                LogUtils.d("signInResult:failed code=" + e.statusCode)

            }

        }

        open fun setGoogleSignListener(googleSignListener: GoogleSignListener?) {

            this.googleSignListener = googleSignListener

        }

        interface GoogleSignListener {

            fun googleLoginSuccess(account: GoogleSignInAccount)

            fun googleLoginFail(message: String?)

            fun googleLogoutSuccess()

            fun googleLogoutFail()

        }

        /**

        * 检查 Google Play 服务

        */

        open fun onCheckGooglePlayServices(activity: Activity, code: Int) {

            // 验证是否已在此设备上安装并启用Google Play服务,以及此设备上安装的旧版本是否为此客户端所需的版本

            GoogleApiAvailability.getInstance().makeGooglePlayServicesAvailable(activity)

            /**

            * 通过isUserResolvableError来确定是否可以通过用户操作解决错误

            */

            if (GoogleApiAvailability.getInstance().isUserResolvableError(code)) {

                GoogleApiAvailability.getInstance().getErrorDialog(activity, code, 200).show()

            }

        }

        fun checkGooglePlayServiceExist(activity: Activity): Int {

            return GoogleApiAvailability.getInstance().isGooglePlayServicesAvailable(activity)

        }

    }

    三、FaceBook登录工具类的封装:


     

    /**

    *@author: njb

    *@date:  2021/5/8 14:26

    *@desc:  FaceBook登录工具类

    */

    open class FacebookLoginUtils(private val activity: Activity) {

        private var loginManager: LoginManager? = null

        private val permissions: List<String>

        private var callbackManager: CallbackManager? = null

        private var requestSuccessCode = 2896

        private var requestCancelCode = 2897

        private var requestFailedCode = 2898

        private var mFaceBookLoginListener: FaceBookLoginListener? = null

        var infoBean: FaceLoginInfoBean? = null

        init {

            //初始化facebook登录服务

            callbackManager = CallbackManager.Factory.create()

            getLoginManager().registerCallback(callbackManager, object : FacebookCallback<LoginResult> {

                override fun onSuccess(result: LoginResult?) {

                    activity.setResult(requestSuccessCode)

                    getLoginInfo(result?.accessToken)

                }

                override fun onCancel() {

                    activity.setResult(requestCancelCode)

                    mFaceBookLoginListener?.onLoginCancel(activity.getString(R.string.login_cancel))

                }

                override fun onError(error: FacebookException?) {

                    activity.setResult(requestFailedCode)

                    mFaceBookLoginListener?.onLoginFail(error?.message)

                    LogUtils.d(error?.message)

                }

            })

            permissions = listOf("email", "user_likes", "user_status", "user_photos", "user_birthday", "public_profile", "user_friends");

        }

        /**

        * 登陆

        */

        fun login() {

            getLoginManager().logIn(activity, permissions)

        }

        /**

        * 退出登陆

        */

        fun loginOut() {

            var logout = activity.resources.getString(R.string.com_facebook_loginview_log_out_action)

            var cancel = activity.resources.getString(R.string.com_facebook_loginview_cancel_action)

            val message: String

            val profile: Profile = Profile.getCurrentProfile()

            message = if (profile?.name != null) {

                java.lang.String.format(

                        activity.resources.getString(

                                R.string.com_facebook_loginview_logged_in_as),

                        profile.name)

            } else {

                activity.resources.getString(

                        R.string.com_facebook_loginview_logged_in_using_facebook)

            }

            val builder: AlertDialog.Builder = AlertDialog.Builder(activity)

            builder.setMessage(message)

                    .setCancelable(true)

                    .setPositiveButton(logout) { _, _ ->

                        getLoginManager().logOut()

                    }

                    .setNegativeButton(cancel, null)

            builder.create().show()

        }

        /**

        * 获取登录信息

        * @param accessToken

        */

        private fun getLoginInfo(accessToken: AccessToken?) {

            var request = GraphRequest.newMeRequest(accessToken, object : GraphRequest.GraphJSONObjectCallback {

                override fun onCompleted(`object`: JSONObject?, response: GraphResponse?) {

                    `object`?.run {

                        val id = optString("id") //比如:13813813888

                        val name = optString("name") //比如:Zhang San

                        val gender = optString("gender") //性别:比如 male (男)  female (女)

                        val email = optString("email") //邮箱:比如:11111@qq.com

                        //获取用户头像

                        val object_pic = optJSONObject("picture")

                        val object_data = object_pic.optJSONObject("data")

                        val photo = object_data.optString("url")

                        //获取地域信息

                        val locale = optString("locale") //zh_CN 代表中文简体

                        infoBean = FaceLoginInfoBean()

                        infoBean?.id = id

                        infoBean?.name = name

                        infoBean?.email = email

                        infoBean?.gender = gender

                        infoBean?.picture = object_pic.toString()

                        infoBean?.data = object_data.toString()

                        infoBean?.photo = photo

                        infoBean?.locale = locale

                        infoBean?.let { mFaceBookLoginListener?.onLoginSuccess(it) }

                    }

                }

            })

            val parameters = Bundle()

            parameters.putString("fields", "id,name,link,gender,birthday,email,picture,locale,updated_time,timezone,age_range,first_name,last_name")

            request.parameters = parameters

            request.executeAsync()

        }

        fun getCallbackManager(): CallbackManager? {

            return callbackManager

        }

        /**

        * 获取loginMananger

        * @return

        */

        private fun getLoginManager(): LoginManager {

            if (loginManager == null) {

                loginManager = LoginManager.getInstance();

            }

            return loginManager!!

        }

        companion object {

            /**

            * 是否处在登陆状态

            */

            fun isLogin(): Boolean {

                val accessToken = AccessToken.getCurrentAccessToken()

                val isLoggedIn = accessToken != null && !accessToken.isExpired

                return isLogin()

            }

        }

        open fun setFaceBookLoginListener(faceBookLoginListener: FaceBookLoginListener?) {

            this.mFaceBookLoginListener = faceBookLoginListener

        }

        interface FaceBookLoginListener {

            fun onLoginSuccess(infoBean: FaceLoginInfoBean)

            fun onLoginCancel(message: String?)

            fun onLoginFail(message: String?)

            fun onLogoutSuccess()

            fun onLogoutFail()

        }

    }

    四、Twitter登录工具类的封装:


     

    **

    * @author: njb

    * @date: 2021/5/14 10:08

    * @desc: Twitter登录工具类

    */

    class TwitterLoginUtils(activity: Activity) {

            private var activityRef: WeakReference<Activity>? = null

            var callback: Callback<TwitterSession>? = null

        @Volatile

        var authClient: TwitterAuthClient? = null

        companion object {

            const val ERROR_MSG_NO_ACTIVITY = ("TwitterLoginButton requires an activity."

                    + " Override getActivity to provide the activity for this button.")

        }

        init {

            activityRef = WeakReference(activity)

            TwitterCore.getInstance()

        }

        fun setOnLoginByTwitterClick(callback: Callback<TwitterSession>?) {

            this.callback = callback

            checkCallback(callback)

            checkActivity(activityRef?.get())

            twitterAuthClient!!.authorize(activityRef?.get(), callback)

        }

        private val twitterAuthClient: TwitterAuthClient?

            get() {

                if (authClient == null) {

                    synchronized(TwitterLoginButton::class.java) {

                        if (authClient == null) {

                            authClient = TwitterAuthClient()

                        }

                    }

                }

                return authClient

            }

        private fun checkCallback(callback: Callback<*>?) {

            if (callback == null) {

                CommonUtils.logOrThrowIllegalStateException(TwitterCore.TAG,

                        "Callback must not be null, did you call setCallback?")

            }

        }

        private fun checkActivity(activity: Activity?) {

            if (activity == null || activity.isFinishing) {

                CommonUtils.logOrThrowIllegalStateException(TwitterCore.TAG, ERROR_MSG_NO_ACTIVITY)

            }

        }

        /**

        * Call this method when [Activity]

        * is called to complete the authorization flow.

        *

        * @param requestCode the request code used for SSO

        * @param resultCode  the result code returned by the SSO activity

        * @param data        the result data returned by the SSO activity

        */

        fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

            if (requestCode == twitterAuthClient!!.requestCode) {

                twitterAuthClient!!.onActivityResult(requestCode, resultCode, data)

            }

        }

    }

     五、具体使用代码如下:

    5.1------使用Google登录时需要先判断用户是否安装Google服务,


     

     5.2------使用具体步骤如下:

     a. 先声明工具类

    private var mGoogleLogin: GoogleLoginUtils? = null

    private var mFacebookLoginUtils: FacebookLoginUtils? = null


     

     b.Google和FaceBook工具类的初始化

    private fun initGoogle() {

        mGoogleLogin = GoogleLoginUtils(this, this)

        mGoogleLogin?.setGoogleSignListener(this)

    }

    private fun initFaceBook() {

        mFacebookLoginUtils = FacebookLoginUtils(this)

        mFacebookLoginUtils?.setFaceBookLoginListener(this)

    }

    c.点击Google和FaceBook两个按钮分别调用不同的方法


     

    R.id.iv_google -> {//先检查是否安装Google服务

        checkGoogleService()

    }

    R.id.iv_face_book -> {//检查是否安装FaceBook客户端

        if (!CheckApkExist.checkFacebookExist(this)) {

            ToastUtils.showShort(getString(com.jiaoday.base.R.string.please_install_face_book_first))

        } else {

            mFacebookLoginUtils?.login()

        }

    }


     

    private fun checkGoogleService() {

        val code = mGoogleLogin?.checkGooglePlayServiceExist(this)

        if (code == ConnectionResult.SUCCESS) {

            mGoogleLogin?.signIn()

        } else {

            code?.let { mGoogleLogin?.onCheckGooglePlayServices(this, it) }

        }

    }

    d.Google和FaceBook登录回调,在最开始继承一下登录回调监听方法:

     GoogleLoginUtils.GoogleSignListener, FacebookLoginUtils.FaceBookLoginListener


     

    e.登录成功、失败、取消登录后的回调


     

    override fun googleLoginSuccess(account: GoogleSignInAccount) {

        //google登录成功后返回的信息

        if (account.email != null) {

            thirdAccountLogin(account.email.toString(), account.email.toString(), "4")

        }

    }

    override fun googleLoginFail(message: String?) {

        ToastUtils.showShort(message)

    }

    override fun googleLogoutSuccess() {

    }

    override fun googleLogoutFail() {

    }

     f.onActivityResult回调结果:


     

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

        super.onActivityResult(requestCode, resultCode, data)

        if (requestCode == mGoogleLogin?.requestCode) {

            val task: Task<GoogleSignInAccount> = GoogleSignIn.getSignedInAccountFromIntent(data)

            mGoogleLogin?.handleSignInResult(task)

        }

        mFacebookLoginUtils?.getCallbackManager()?.onActivityResult(requestCode, resultCode, data)

    }

     六、登录成功后处理自己的登录逻辑,调用第三方登录接口,这里Google登录使用的是最新的api,如果找不到导包大家可以修改版本,后面会给出源码地址,这里只是简单说出使用步骤,这里基本上三种登录都已经在项目中成功使用,大家可以尝试一下,如有问题,及时提出,我会修改.
