准备
在 https://github.com/settings/developers 注册授权应用 获取appid appsecret 设置callbackurl
Application name -----------------应用名
Homepage URL -----------------主页URL，这里我填写的是本地测试的URL地址
Application description -----------------应用描述
Authorization callback URL -----------------后端回调URL
即自己实现的逻辑 主要是获取code 使用appid appsecret 获取auth_token 再使用auth_token获取用户信息 内部逻辑处理
流程
1，首先使用申请好的appid和设置好的callbackurl 去请求github授权url
https://github.com/login/oauth/authorize?client_id=4520e5d3f7afa74b26c0&redirect_uri=http://localhost:5000/customer/github/redirect
2，跳转到github登录界面 登录授权后重定向到回调url http://localhost:5000/customer/github/redirect github会返回code参数
http://localhost:5000/customer/github/redirect?code=765a0b9808771482bcc0
3，执行回调url自己实现的逻辑，即http://localhost:5000/customer/github/redirect?code=765a0b9808771482bcc0路由
3-1，使用appid和appsecret以及code参数获取auth_token，
https://github.com/login/oauth/access_token?client_id=4520e5d3f7afa74b26c0&client_secret=fbfde7bd7af8a98c1d3ffceed80294dff41613b9&code=765a0b9808771482bcc0
3-2，github返回auth_token
返回body为json，取access_token字段
3-3 拿着 auth_token 获取用户信息
用户url： https://api.github.com/user
token放到请求头
headers = {
'accept':'application/json',
'Authorization': access_token
}
3-4，拿到用户信息处理自己的逻辑，缓存redis 存数据库 登录逻辑等
