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

functioncurlHtml($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;
}
classWechat

public$errmsg;
//微信登录获取用户信息
publicfunctiongetUserInfo(){
//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);
$snsapi_base_url='https://open.weixin.qq.com/connect/oauth2/authorize?appid='.config('system.appid').'&redirect_uri='.$baseurl.'&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect';
//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
$curl='https://api.weixin.qq.com/sns/oauth2/access_token?appid='.config('system.appid').'&secret='.config('system.appsecret').'&code='.$code.'&grant_type=authorization_code';
