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_VERIFYHOST, false);
 $output = curl_exec($ch);
 //释放curl句柄
 curl_close($ch);
 return $output;
}

 //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
