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

<!--servlet服务--><dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency><!--第三方登录插件包--> <dependency> <groupId>me.zhyd.oauth</groupId> <artifactId>JustAuth</artifactId> <version>1.3.2</version> </dependency><!--服务器发送get，post工具包--> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.2</version> </dependency>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<String,String> 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：在这小编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：小编使用的是服务器的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
