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)

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);

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
