原生java代码实现码云第三方验证登录的示例代码

码云第三方验证登录

研究了QQ，码云，微信等第三方登录接口时，发现QQ以及微信第一步都需要验证授权管理，而且个人测试需要提供手持身份证一张，并且验证时间过长( 3天工作日左右吧 )，这样会非常浪费大家学习第三方接口登录的时间，终于， 在我的不屑努力下，找到了适合大家快速上手，测试第三方接口登录的平台-————码云（看网上帖子说某WX接入还要开发者认证，人民币300元）

码云链接地址

https://gitee.com/

一、在码云上创建应用

1、在码云上注册一个账号，点击右上角设置

2、创建应用

3、填写资料

很多同学不太了解什么是应用回调地址webhooks（第三方登录成功后，会返回到你指定的地址，并且携带验证是否成功的参数信息）

4、获取到clientId以及client Secret

clientId和client Sercret的主要作用是通过拼接得到请求地址，将地址重定向至授权登录页面

准备过程已完成

二、在项目中实现第三方登录

大概流程

1、导入依赖jar包

javax.servlet

javax.servlet-api

3.1.0

me.zhyd.oauth

JustAuth

1.3.2

org.apache.httpcomponents

httpclient

4.5.2

2、跳转授权页面

AuthRequest authRequest = new AuthGiteeRequest(AuthConfig.builder()

.clientId(CLIENT_ID) //Client ID

.clientSecret(CLIENT_SECRET) //Client Secret

.redirectUri(REDIRECTURI) //回调地址

.build());

String authorizeUrl = authRequest.authorize(AuthStateUtils.createState());

//跳转到授权页面

response.sendRedirect(authorizeUrl);

3、通过回调地址获取到code值

//http://localhost:8080/login?actionName=giteeCode&code=e063730161cd40cf&state=25c74eba2ac5f

String code = request.getParameter("code");

4、再将用户授权码发送码云服务器

补充一个小小的坑，码云第三方验证需要加上header信息，否则会报403错误

String url = "https://gitee.com/oauth/token?grant_type=authorization_code&code="+code+"&client_id="+CLIENT_ID+"&redirect_uri="+REDIRECTURI+"&client_secret="+CLIENT_SECRET;

Map map = new HashMap<>();

map.put("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36)");

jsONObject s = HttpUtils.post(url,map);

授权登录失败会返回message错误信息，标识登录失败

成功:

{

"access_token":"e386e20327b7c4",

"refresh_token":"057c79c2d1f957a5cb4d",

"scope":"user_info",

"created_at":15488,

"token_type":"bearer",

"expires_in":86400

}

5、获取码云用户信息

通过授权码获取到的json数据，其中access_token参数，可以访问码云的用户数据

//https://gitee.com/api/v5/user?access_token=*******

String access_token = s.getString("access_token");

String url2 = "https://gitee.com/api/v5/user?access_token="+access_token;

JSONObject user = HttpUtils.get(url2,map);

//1、设置响应类型输出流

response.setContentType("application/json;charset=UTF-8");

//2、将json转为字符串

String str = JSON.toJSONString(user);

//3、得到字符输出流

response.getWriter().write(str);

源码：

在这要说一下回调地址操作1和回调地址操作2的区别

操作1：使用的是服务器的get,post发送请求，而跳转“授权页面”（giteeLogin 方法）使用的是插件，各位看主大大也可手动改为get请求，跳转第三方登录页面，具体get地址请参考

码云oauth文档

其中A和B步骤，修改后就可以不用插件代码跳转授权页面

操作2：完全使用的是JustAuth插件实现第三方登录
