這里的實現主要用JS_SDK來實現，通過這種實現回調地址基本沒有什么用，區別於這種實現方式：如何在自己的網站上實現QQ授權登錄？。步驟就不一一說了，直接上代碼（紅色部分為qq授權相關的，里面的appid和回調地址改成自己申請時候的既可）

這里用到的是 QC.Login.showPopup，期間遇到了showPopup 這種不能回調的情況，參考了：QC.Login.showPopup可有回調？ 。
qq授權后台處理思路：通過點擊qq登錄，登錄成功后回調，在回調中通過 QC.api("get_user_info")獲取登錄后的信息，在后台通過qq的openid來查詢數據庫，若是庫中有值，則直接進入登錄成功流程，若是沒有值則跳轉到手機號注冊流程。（回調地址里面基本為空）
3.2、微信授權登錄實現
上面代碼的藍色部分即為微信登錄的連接，相應地方改成申請的既可.
這里有三個地方需要注意：
1、地址需要改成轉義后的，%3A%2F%2F就等於://這樣的形式。
2、若是前面微信開放平台的是https，對應的回調也是https。
3、這里寫的回調地址是http://www.xxxxxx.com/security/getWebchatCode.do，但是微信申請里寫http://www.xxxxxx.com既可。
下面看看微信登錄成功后的后台處理代碼
/** * 微信登錄獲取code */ @RequestMapping(value = "/getWebchatCode.do") public ModelAndView getWebchatCode(HttpServletRequest request, HttpServletResponse response) { String code = request.getParameter("code"); System.out.println("微信登錄獲取code=="+code); String url="https://api.weixin.qq.com/sns/oauth2/access_token?appid="+appid+"&secret=XXX&code="+code+"&grant_type=authorization_code"; Map<String, Object> map = new HashMap<String, Object>(); map.put("from", code); try { JSONObject jb = HttpUtils.httpRequest(url,"GET",null); System.out.println("通過code獲取token=="+jb.toString()); String access_token= jb.getString("access_token"); JSONObject userinfo = HttpUtils.httpRequest("https://api.weixin.qq.com/sns/userinfo?access_token="+access_token+"&openid="+appid+"","GET",null); System.out.println("通過token獲取=="+userinfo.toString()); String loginName= userinfo.getString("nickname"); String openId=userinfo.getString("openid"); Member member = memberService.selectOneByWeixinOpenId(openId); if (member != null ) {//通過qq唯一openID判斷該qq是否之前用過，同時判斷loginName是否唯一 member.setLastLoginTime(new Date()); memberService.update(member); // 設置線程變量 CurrentThreadContext.setValue(CurrentThreadContext.CURRENT_USER_ID, member.getId()); CurrentThreadContext.setValue(CurrentThreadContext.CURRENT_MEMBER, member); CurrentThreadContext.setValue(CurrentThreadContext.CURRENT_MANAGE_SHOP_ID, member.getManageShopId()); // 單點登錄Cookie Cookie cookie_sso = new Cookie(CurrentThreadContext.COOKIES_LOGIN_KEY, AESUtil.encrypt(loginName, PropertiesUtil.getInstance().getValue("security.cipher.key"))); cookie_sso.setMaxAge(-1); cookie_sso.setDomain(PropertiesUtil.getInstance().getValue("security.root.domain")); cookie_sso.setPath("/"); response.addCookie(cookie_sso); // 用戶Cookie loginName = DESUtil.strEnc(loginName, PropertiesUtil.getInstance().getValue("security.cipher.key"), "", ""); String shopFlage = ""; if (member.getManageShopId() != null) { Shop t = new Shop(); t.setId(member.getManageShopId()); Shop shop = shopApiService.selectOne(t); if (shop != null && shop.getStatus() != null && shop.getStatus().equals(ShopConstant.SHOP_STATUS_3)) { shopFlage = member.getManageShopId().toString(); } } Cookie cookie_memberinfo = new Cookie(CurrentThreadContext.COOKIES_MEMBERINFO, loginName + "|" + shopFlage + "|" + member.getId()); cookie_memberinfo.setMaxAge(-1); cookie_memberinfo.setDomain(PropertiesUtil.getInstance().getValue("security.root.domain")); cookie_memberinfo.setPath("/"); response.addCookie(cookie_memberinfo); map.put("code", "200"); map.put("msg", "登錄成功"); return new ModelAndView("redirect:/",map); } else { //qq授權的不存在，跳轉到輸入手機驗證碼的地方 map.put("code", "101"); Member membertemp = memberService.selectOneByLoginName(loginName); if(membertemp!=null){ map.put("loginName", loginName+"_xima"+new Random().nextInt(1000)); }else{ map.put("loginName", loginName); } map.put("wqType", "weixin"); map.put("openId", openId); /* map.put("msg", "用戶名或密碼不正確");*/ return new ModelAndView("security/qwRegister",map); } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return new ModelAndView("security/login",map); }
主要是幾次握手過程。
四、總結
qq微信的第三方登錄按照官方文檔一步一步實習還是比較容易的，有什么問題可以交流交流。
