微信群控系统制作系列一——java模拟登录网页版微信

PS：很多人咨询我怎么做手机群控系统，因此我开了个制作群控系统的系列，准备分五期讲解群控系统的制作。前两篇是基础内容。

今天做个简单的java模拟登录网页版微信。

既然要做模拟登录，那么我们一定要了解整个登录过程，我们这就来真实操作一遍：当我们登录网页版微信后会出现个扫码登录的窗口，我们扫码二维码成功后就跳转到登录成功页面并重定向到网页版微信。

那么我们的目标是做一个工具，当启动会帮我们调用微信的二维码接口，下载二维码图片，然后在后台展示二维码让我们扫码，扫码成功后跳转到网页版微信。

梳理后我们将进行下面的动作：

1 获取二维码

2 下载图片

3 弹出二维码扫码框

4 检查是否登录

5 登录网页版

请求的地址就直接贴出来了，需要的自行抓包（可以使用charles，fiddler，鲨鱼，浏览器F12）
