Yii使用EasyWechat实现小程序获取用户的openID的方法

poser require jianyan74/yii2-easy-wechat

'wechat' => [ 
  'class' => 'jianyan\easywechat\Wechat', 
  'userOptions' => [], // 用户身份类参数 
  'sessionParam' => 'wechatUser', // 微信用户信息将存储在会话在这个密钥 
  'returnUrlParam' => '_wechatReturnUrl', // returnUrl 存储在会话中 
  'rebinds' => [ // 自定义服务模块 
  ] 
], 

// 微信小程序配置 
'wechatMiniProgramConfig' => \[ 
  'app\_id' => 'XXXX', 
  'secret' => 'XXXX', 
  // 狼蚁网站SEO优化为可选项 
  // 指定 API 调用返回结果的类型array(default)/collection/object/raw/自定义类名 
  'response\_type' => 'array', 
  //日志配置 
  'log' => \[ 
    'level' => 'debug', 
    'file' => dirname(dirname(\_\_DIR\_\_)) . '/api/runtime/wechat.log', 
  \], 
\], 

$request = Yii::$app->getRequest(); 
$miniProgram = Yii::$app->wechat->miniProgram; 
$code2Session = $miniProgram->auth->session($request->post('code', '')); 
$openID = $code2Session\['openid'\];//用户的openID 
$sessionKey = $code2Session\['session\_key'\];//session\_key 

wx.login({ 
 suess (res) { 
  if (res.code) { 
   //获取code 
   console.log(res.code) 
   }) 
  } else { 
   console.log('登录失败！' + res.errMsg) 
  } 
 } 
})
