thinkphp5框架结合mysql实现微信登录和自定义分享链接与图文功能示例


						本文实例讲述了thinkphp5框架结合mysql实现微信登录和自定义分享链接与图文功能。分享给大家供大家参考，具体如下：

php代码





function curlHtml($url){

  $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, $url);

  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

  curl_setopt($ch, CURLOPT_HEADER, 0);

  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

  $output = curl_exec($ch);

  //释放curl句柄

  curl_close($ch);

  return $output;

}

  public $errmsg;

  //微信登录获取用户信息

    //1.准备scope为snsapi_base网页授权页面

    //2.静默授权,获取code

    //页面跳转至redirect_uri/?code=CODE&state=STATE

    $code = input('code');

    if (!isset($code) || empty($code)) {

      header('Location:' . $snsapi_base_url);exit(0);

    }

    //3.通过code换取网页授权access_token和openID

    $curl = 'http://api.weixin.qq.com/sns/oauth2/access_token?appid=' . config('system.appid') . '&secret=' . config('system.appsecret') . '&code=' . $code . '&grant_type=authorization_code';
