我是靠谱客的博主野性皮皮虾，最近开发中收集的这篇文章主要介绍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，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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') . '&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';
    $content = curlHtml($curl);
    $result = json_decode($content, true);
    if(!isset($result['openid'])) {
      $this->errmsg = $result['errmsg'];return false;
    }
    $openid = $result['openid'];
    $userinfo = $this->getUserByOpenid($openid);
    return $userinfo;
  }
  private function getUserByOpenid($openid) {
    //获取access_token
    $token_info  = $this->curlGetWxAccessToken();
