碼云第三方驗證登錄

研究了QQ，碼云，微信等第三方登錄接口時，發(fā)現(xiàn)QQ以及微信第一步都需要驗證授權(quán)管理，而且個人測試需要提供手持身份證一張，并且驗證時間過長( 3天工作日左右吧 )，這樣會非常浪費大家學(xué)習(xí)第三方接口登錄的時間，終于， 在我的不屑努力下，找到了適合大家快速上手，測試第三方接口登錄的平臺-————碼云（看網(wǎng)上帖子說某WX接入還要開發(fā)者認(rèn)證，人民幣300元）碼云鏈接地址https://gitee.com/

一、在碼云上創(chuàng)建應(yīng)用1、在碼云上注冊一個賬號，點擊右上角設(shè)置

2、創(chuàng)建應(yīng)用

3、填寫資料

很多同學(xué)不太了解什么是應(yīng)用回調(diào)地址webhooks（第三方登錄成功后，會返回到你指定的地址，并且攜帶驗證是否成功的參數(shù)信息）

4、獲取到clientId以及client Secret

clientId和client Sercret的主要作用是通過拼接得到請求地址，將地址重定向至授權(quán)登錄頁面

準(zhǔn)備過程已完成

二、在項目中實現(xiàn)第三方登錄

大概流程

1、導(dǎo)入依賴jar包

<!--servlet服務(wù)--><dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> </dependency><!--第三方登錄插件包--> <dependency> <groupId>me.zhyd.oauth</groupId> <artifactId>JustAuth</artifactId> <version>1.3.2</version> </dependency><!--服務(wù)器發(fā)送get，post工具包--> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.2</version> </dependency>2、跳轉(zhuǎn)授權(quán)頁面

AuthRequest authRequest = new AuthGiteeRequest(AuthConfig.builder().clientId(CLIENT_ID) //Client ID.clientSecret(CLIENT_SECRET) //Client Secret.redirectUri(REDIRECTURI) //回調(diào)地址.build());String authorizeUrl = authRequest.authorize(AuthStateUtils.createState());//跳轉(zhuǎn)到授權(quán)頁面response.sendRedirect(authorizeUrl);3、通過回調(diào)地址獲取到code值

//http://localhost:8080/login?actionName=giteeCode&code=e063730161cd40cf&state=25c74eba2ac5f String code = request.getParameter('code');4、再將用戶授權(quán)碼發(fā)送碼云服務(wù)器

補(bǔ)充一個小小的坑，碼云第三方驗證需要加上header信息，否則會報403錯誤

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);

授權(quán)登錄失敗會返回message錯誤信息，標(biāo)識登錄失敗

成功:

{'access_token':'e386e20327b7c4','refresh_token':'057c79c2d1f957a5cb4d','scope':'user_info','created_at':15488,'token_type':'bearer','expires_in':86400}5、獲取碼云用戶信息

通過授權(quán)碼獲取到的json數(shù)據(jù)，其中access_token參數(shù)，可以訪問碼云的用戶數(shù)據(jù)

//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、設(shè)置響應(yīng)類型輸出流response.setContentType('application/json;charset=UTF-8');//2、將json轉(zhuǎn)為字符串String str = JSON.toJSONString(user);//3、得到字符輸出流response.getWriter().write(str);

源碼：在這小編要說一下回調(diào)地址操作1和回調(diào)地址操作2的區(qū)別操作1：小編使用的是服務(wù)器的get,post發(fā)送請求，而跳轉(zhuǎn)“授權(quán)頁面”（giteeLogin 方法）使用的是插件，各位看主大大也可手動改為get請求，跳轉(zhuǎn)第三方登錄頁面，具體get地址請參考碼云oauth文檔其中A和B步驟，修改后就可以不用插件代碼跳轉(zhuǎn)授權(quán)頁面

操作2：完全使用的是JustAuth插件實現(xiàn)第三方登錄
