1,注册应用，获取Client ID
登录码云，鼠标移到头像，点击设置按钮，右边点击第三方应用，点击创建应用

填写信息，回调地址一定要填好

发请求拉起授权页面
<div class="cnblogs_code">
<pre><a href="https://gitee.com/oauth/authorize?client_id= 你的clientId&redirect_uri你的回调地址&response_type=code">gitee登录</a></pre>
<pre> </pre>
</div>
输入账号密码后，会回调到你自己填的回调地址并且带给你一个参数code，获取code再次发送post请求
https://gitee.com/oauth/token?grant_type=authorization_code&code=你拿到的code&client_id=你自己的clientId&redirect_uri=自己的回调地址&client_secret=你自己的client_secret
然后码云那边会返回给你一个令牌，access_token
拿着这个access_token再次发送get请求去获取用户信息
https://gitee.com/api/v5/user?access_token=拿到的access_token
这里有2个坑：在发送post去获取令牌的时候必须要把User-Agent设置为： Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 
发送get请求获取用户资源信息也是一样。
