SSO单点登录---Gitee(码云)

该项目参考Gitee官方的OAuth文档来实现授权过程

Gitee授权登录流程图

认证流程!

该项目使用了授权码的模式来完成!

1.应用通过 浏览器 或 Webview 将用户引导到码云三方认证页面上( GET请求

https://gitee.com/oauth/authorize?client_id={client_id}&redirect_uri={redirect_uri}&response_type=code

2.用户对应用进行授权

如果之前已经授权过的需要跳过授权页面,需要在上面第一步的 URL 加上 scope 参数,且 scope 的值需要和用户上次授权的勾选的一致。如用户在上次授权了user_info、projects以及pull_requests。则步骤A 中 GET 请求应为:

https://gitee.com/oauth/authorize?client_id={client_id}&redirect_uri={redirect_uri}&response_type=code&scope=user_info%20projects%20pull_requests

3.码云认证服务器通过回调地址{redirect_uri}将 用户授权码 传递给 应用服务器 或者直接在 Webview 中跳转到携带 用户授权码的回调地址上,Webview 直接获取code即可({redirect_uri}?code=abc&state=xyz)

4.应用服务器 或 Webview 使用 access_token API 向 码云认证服务器发送post请求传入 用户授权码 以及 回调地址( POST请求注:请求过程建议将 client_secret 放在 Body 中传值,以保证数据安全。

https://gitee.com/oauth/token?grant_type=authorization_code&code={code}&client_id={client_id}&redirect_uri={redirect_uri}&client_secret={client_secret}

5.码云认证服务器返回 access_token,应用通过 access_token 访问 Open API 使用用户数据。

6.当 access_token 过期后(有效期为一天),你可以通过以下 refresh_token 方式重新获取 access_token( POST请求

https://gitee.com/oauth/token?grant_type=refresh_token&refresh_token={refresh_token}

涉及网络请求

网络请求文档:https://square.github.io/okhttp/

利用Java代码向第三方服务器发送get或post请求时,可以使用OkHttp来实现
