获取AppID，AppSecret，之后的处理：

需要在你想加的网站登录页给一个链接：http://www.sunmil.cn/passport-linshi.html&response_type=code&scope=snsapi_login&state=STATE#wechat_redirect">微信登录

处理微信登录开始

定义appid appsecert

    private $appid = "your appid";
    private $appsecert = "your appsecert";
    private $redirect_uri = "http://www.sunmil.cn/wxGetCode";

绑定账号页面

  public function weixin(){
        //链接数据库
        $link = mysqli_connect(DB_HOST, DB_USER,DB_PASSWORD,DB_NAME ) or die(&＃39;数据库连接失败4&＃39;);
        $link = mysqli_connect(&＃39;127.0.0.1&＃39;, &＃39;root&＃39;,&＃39;root&＃39;, &＃39;ec&＃39;) or die(&＃39;数据库连接失败&＃39;);
        mysqli_set_charset($link,&＃39;utf8&＃39;);

        //接收openid
        $openid = $_COOKIE[&＃39;openid&＃39;];

        $sql = "select * from sdb_trustlogin_trustinfo where openid = &＃39;$openid&＃39; ";
        $res = mysqli_query($link, $sql);
        $row = mysqli_fetch_assoc($res);

        $this->pagedata[&＃39;realname&＃39;] = $row[&＃39;realname&＃39;];
        $this->pagedata[&＃39;avatar&＃39;] =  $row[&＃39;avatar&＃39;];

        $this->page("site/passport/weixin.html");

    }

当第一次微信登录，处理绑定账号页面

处理微信登录结束

就可以实现微信登录了，当然了，一个简单熟悉微信第三登录的demo，有机会用tp框架分装完善一个完整的微信第三方登录。

欢迎留言，大家一起讨论。

以上就是微信第三方登录demo 的详细内容，更多请关注 第一PHP社区 其它相关文章！
