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;}class Wechat{  public $errmsg;  //微信登录获取用户信息  public function getUserInfo() {    //1.准备scope为snsapi_base网页授权页面    $redirect_url = config('system.site_url') . $_SERVER["REQUEST_URI"];    $baseurl = urlencode($redirect_url);    $snsapi_base_url = 'https://open.weixin.qq.com/connect/oauth2/authorize?appid=' . config('system.appid') .
