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.
