【第三方登录】Google邮箱

登录谷歌邮箱开发者

https://console.developers.google.com/

• 先创建项目
  
  

  
  

我们用的web应用

• 设置回调
  

核心主要：
1.创建应用  
2.创建客户端ID 
3.设置域名和重定向URL 
4.对外公开，这样所有的gmail邮箱 都能参与测试

PHP代码实现

• 引入第三方包
  https://github.com/googleapis/google-api-php-client/releases
• 获取第三方跳转链接接口

    public function googleUrl()
    {
        global $db,$request,$comId;
        //引入第三方包
        require_once 'inc/google_client/vendor/autoload.php';  
        
        $googleConfig = array(
            "client_id"=>"客户端ID",
    		"project_id"=>"hudong",//项目名称
    		"auth_uri"=>"https://accounts.google.com/o/oauth2/auth",
    		"token_uri"=>"https://oauth2.googleapis.com/token",
    		"auth_provider_x509_cert_url"=>"https://www.googleapis.com/oauth2/v1/certs",
    		"client_secret"=>"客户端秘钥",
    		"redirect_uris"=>["https://vip.com/Google"],//设置的回调结合 可以设置多个
    		"javascript_origins"=>["https://vip.com"]//设置的获取JavaScript的来源配置  
        );
        
    	$clientID = $googleConfig['client_id'];
    	$clientSecret = $googleConfig['client_secret'];
        $redirectUri = $googleConfig['callBack'] = "https://vip.com/Google"; //当前项目回调地址
 
    // create Client Request to access Google API
        $client = new \Google_Client();

        $client->setClientId($clientID);
        $client->setClientSecret($clientSecret);
        $client->setRedirectUri($redirectUri);
        $client->addScope("email");
        $client->addScope("profile");
        // authenticate code from Google OAuth Flow
       
        $loginUrl = $client->createAuthUrl();
           
        $return['code'] = 1;
   		$return['message'] = '获取成功';
   		$return['data'] = array();
   		$return['data']['url'] = $loginUrl;
   		
   		return json_encode($return,JSON_UNESCAPED_UNICODE); 
    }

• 跳转之后 ，前端获取code 传给后台，读取邮箱相关信息

 public function googleLogin()
    {
        global $db,$request,$comId;
        
        require_once 'inc/google_client/vendor/autoload.php';  
        
        // echo ABSPATH.'inc/google_client/vendor/autoload.php';  die;
        // require '../lib/internal/google-api-php-client--PHP7.0/vendor/autoload.php';  
       
        // $googleConfig = $this->snsaccount->googleAccount();
        
        $googleConfig = array(
            "client_id"=>"客户端ID",
    		"project_id"=>"hudong",//项目名称
    		"auth_uri"=>"https://accounts.google.com/o/oauth2/auth",
    		"token_uri"=>"https://oauth2.googleapis.com/token",
    		"auth_provider_x509_cert_url"=>"https://www.googleapis.com/oauth2/v1/certs",
    		"client_secret"=>"客户端秘钥",
    		"redirect_uris"=>["https://vip.com/Google"],//设置的回调结合 可以设置多个
    		"javascript_origins"=>["https://vip.com"]//设置的获取JavaScript的来源配置  
        );
        
    	$clientID = $googleConfig['client_id'];
    	$clientSecret = $googleConfig['client_secret'];
        $redirectUri = $googleConfig['callBack'] = "https://tocmodels.com/Google";  //Google console redirect URI 
        
        $client = new \Google_Client();

        $client->setClientId($clientID);
        $client->setClientSecret($clientSecret);
        $client->setRedirectUri($redirectUri);
        $client->addScope("email");
        $client->addScope("profile");
        
        $code = $request['code'];
        if(empty($code)) return '{"code":0,"message":"code为必传参数"}';
        
        $token = $client->fetchAccessTokenWithAuthCode($request['code']);
        // var_dump($token);
        if(isset($token['error'])) return '{"code":0,"message":"'.$token['error'].'"}';
        $client->setAccessToken($token['access_token']);
        // get profile info
        $google_oauth = new \Google_Service_Oauth2($client);
        $google_account_info = $google_oauth->userinfo->get();
        
        $email = $google_account_info->email;//谷歌邮箱
        $gid =  $google_account_info->id;//谷歌id
        $gname = $google_account_info->name;//谷歌实名
        $image = $google_account_info->picture;//谷歌头像
        
      
    }
