yii接入apple第三方登錄

app中要接入apple賬號的第三方登錄，這裏只記錄後端的東西，app中獲取數據的過程是由前端小哥搞定的，後端的驗證步驟一共三步

1. 檢查appleId是否在本地註冊了，已經註冊過就自動登錄，否則通過apple提供的接口進行簽名的校驗並在本地第三方表中註冊appleId
2. appleId與用戶主表進行關聯綁定
3. 進行登錄操作

登錄過程用到了兩張表，一張是user，用戶主表，裏邊存放的是用戶的信息，如mobile、nickname等，我們的用戶信息是通過mobile來進行唯一性判定的，另外一張表是user_apple,裏邊存放的是前端傳過來的蘋果用戶信息，有蘋果的唯一標識、名字、郵箱等信息，

在接入過程中需要對前臺傳遞的apple簽名進行校驗，所以我從網上找了一個擴展包，在做簽名校驗的時候使用，我用的yii，就以yii爲例，擴展包地址https://github.com/GriffinLedingham/php-apple-signin,可以直接composer安裝，命令如下：

composer require wubuwei/php-apple-signin

我這邊不知道是什麼原因，就是下載不了，切換了阿里雲的composer鏡像也不行，所以只好手動安裝啦，把擴展包手動下載完了之後放到vendor文件夾下邊，然後需要引入一下命名空間，不然不能使用，在common下的配置文件main.php中加入如下代碼就可以了

[
   'aliases' => [
      '@AppleSignIn' => '@vendor/wubuwei/php-apple-signin',
   ],
]
//"@AppleSignIn"就是命名空間，"@vendor/wubuwei/php-apple-signin"是文件的路徑

下邊是第一個接口的代碼，作用是檢查appleId和對appleId進行本地註冊

use AppleSignIn\ASDecoder;
use common\classes\Service\ParamsValidateService;

 /**

     */
    public function actionLoginByApple()
    {
        $PVS = new ParamsValidateService();
        $data=\Yii::$app->request->post();
        $valid = $PVS->validate($data, [
            [['access_token','openid'], 'required'],
            [['access_token','openid','familyName','giveName','givenName','email'], 'string'],
        ]);
        if (!$valid) return $this->returnData(0, '數據參數錯誤', $PVS->getErrorSummary(true));
        $ip = Yii::$app->request->getUserIP();

        $userApple = UserApple::findOne(['openid'=>$data['openid']]);

        if($userApple && $userApple->uid){
            $userInfo = User::findOne($userApple->uid);
            if(!$userInfo) return $this->returnData(1, '數據錯誤',$userInfo);
            $res = User::LoginReuslt($userInfo);
            if($res){
                User::updateData(array('last_login_time' => time()),$userInfo->id);
                return $this->returnData(1, '註冊成功',$res);
            }else{
                return $this->returnData(0, '操作失敗，請稍後再試！');
            }
        }
        try{
            $appleSignInPayload = ASDecoder::getAppleSignInPayload($data['access_token']);
            $check = $appleSignInPayload->verifyUser($data['openid']);
            if(!$check) throw new \Exception("簽名認證失敗");
            $model = new UserApple();
            $model->openid = $data['openid'];
            $model->createtime = time();
            $model->ip = $ip;
            $model->family_name = isset($data['familyName'])?$data['familyName']:'';
            $model->give_name = isset($data['giveName'])?$data['giveName']:'';
            $model->given_name = isset($data['givenName'])?$data['givenName']:'';
            $model->email = isset($data['email'])?$data['email']:'';
            $model->save();
            $errors = $model->getErrors();
            if($errors) throw new \Exception(json_encode($errors));
        }catch (\Exception $e){
            return $this->returnData(0, '登錄失敗', $e->getMessage());
        }

        return $this->returnData(2, '請綁定用戶',[]);
    }

然後是appleId與用戶表進行關聯

   /**

     * @api POST /v1/user/apple-associated-user
     * @param  string   mobile 用戶手機號
     * @param  string   openid    用戶標識
     * @return mixed    $data 其他數據
     */
    public function appleAssociatedUser($data)
    {
        $time = time();
        $userApple = UserApple::findOne(['openid'=>$data['openid']]);
        if(!$userApple){
            return [
                'status'=>0,
                'data'=>'請先進行蘋果授權'
            ];
        }
        if($userApple->uid) {
            return [
                'status'=>0,
                'data'=>'已經關聯過用戶了'
            ];
        }
        $user = User::findOne(['mobile'=>$data['mobile']]);
        if(!$user){
            $ip = Yii::$app->request->getUserIP();
            $user = new User();
            $user->mobile = $data['mobile'];
            $user->username = $userApple->family_name.$userApple->give_name;
            $user->nickname = $userApple->give_name;
            $user->status = 1;
            $user->last_login_time = $time;
            $user->created = $time;
            $user->last_login_ip = $ip;
            $user->save();
            $errors = $user->getErrors();
            if($errors){
                return [

            }

        $userApple->uid = $user->id;
        $userApple->save();
        $errors = $userApple->getErrors();
        if($errors){
            return [
                'status'=>0,
                'data'=>json_encode($errors)
            ];
        }

        return [

            'data'=>'',
        ];
    }
