oauth2 authorization code 大致流程

用户打开客户端后，客户端要求用户给予授权。

用户同意给予客户端授权。

客户端使用授权得到的code，向认证服务器申请token令牌。

认证服务器对客户端进行认证以后，确认无误，同意发放令牌。

客户端请求资源时携带token令牌，向资源服务器申请获取资源。

资源服务器确认令牌无误，同意向客户端开放资源。

1. 访问oauth2 服务

client_id：第三方应用在授权服务器注册的 Id

response_type：固定值　code。

redirect_uri：授权服务器授权重定向哪儿的 URL。

scope：权限

state：随机字符串，可以省略

如果未登陆则出现登录页面，输入用户名：admin 密码：123456 登陆系统

2. 成功登陆后自动跳转到授权页面

3. 携带授权之后返回的code 获取token

这里的账号和密码 是我们注册的 client_id 和 client_secret
