网站实现使用公众号信息登录,不使用开放平台
如下效果
做下记录,后续使用直接复制即可
首先在开放平台绑定域名
然后就是代码部分
使用类
use EasyWeChat\Factory;
use EasyWeChat\Kernel\Messages\Article;
use EasyWeChat\Kernel\Messages\News;
use EasyWeChat\Kernel\Messages\NewsItem;
use EasyWeChat\Kernel\Messages\Media;

判断是否登录 layui.use('layer', function(){ var layer = layui.layer; function reqs() { $.post("{:url('index/gzh_login_is')}",function(res){ if(res.result==1){ layer.msg(res.msg); setTimeout(function(){ top.location.reload() },2000); } },'json'); } reqs(); setInterval(reqs, 3000); }); |
实现原理:
其实很简单
就是登录的时候带一个token,然后手机扫码登录的时候,把token记录到当前的用户信息,然后轮询查找用户表是否存在这个token,如果搜索到此token,就找到了当前的登录用户
