QQ第三方登入
1.首先就是去QQ互聯登入申請了，為什麼要申請呢，是應為他會給你分配一個appid和一個appkey給，不然你是沒有資格去第三方登入的，申請大概一個星期左右

**
唯一需要注意的是第二個 回撥地址了 這個是可以隨時修改的

2.獲取到了appid和appkey然後我們就需要開發後臺了
我們先去獲取java sdk 記得是java sdk不是js sdk
java SDk 下載
解壓：

然後將jar包放入自己的專案

有興趣的可以讀一下 ReadMe.txt 瞭解更詳細 我們繼續下一步
開啟qqconnectconfig.properties

app_ID = 100****(請修改此處)
app_KEY = ******(請修改此處)
redirect_URI = ***********(請修改此處)
scope = get_user_info,add_topic,add_one_blog,add_album,upload_pic,list_album,add_share,check_page_fans,add_t,add_pic_t,del_t,get_repost_list,get_info,get_other_info,get_fanslist,get_idollist,add_idol,del_ido,get_tenpay_addr(請修改此處)
baseURL = https://graph.qq
 
.com/
getUserInfoURL = https://graph.qq.com/user/get_user_info
accessTokenURL = https://graph.qq.com/oauth2.0/token
authorizeURL = https://graph.qq.com/oauth2.0/authorize
getOpenIDURL = https://graph.qq.com/oauth2.0/me
addTopicURL = https://graph.qq.com/shuoshuo/add_topic
addBlogURL = https://graph.qq.com/blog/add_one_blog
addAlbumURL = https://graph.qq
 
.com/photo/add_album
uploadPicURL = https://graph.qq.com/photo/upload_pic
listAlbumURL = https://graph.qq.com/photo/list_album
addShareURL = https://graph.qq.com/share/add_share
checkPageFansURL = https://graph.qq.com/user/check_page_fans
addTURL = https://graph.qq.com/t/add_t
addPicTURL = https://graph.qq.com/t/add_pic_t
delTURL = https://graph.qq.com/t/del_t
getWeiboUserInfoURL = https://graph.qq.com/user/get_info
getWeiboOtherUserInfoURL = https://graph.qq.com/user/get_other_info
getFansListURL = https://graph.qq.com/relation/get_fanslist
getIdolsListURL = https://graph.qq.com/relation/get_idollist
addIdolURL = https://graph.qq.com/relation/add_idol
delIdolURL = https://graph.qq.com/relation/del_idol
getTenpayAddrURL = https://graph.qq.com/cft_info/get_tenpay_addr
getRepostListURL = https://graph.qq.com/t/get_repost_list
version = 2.0.0.0

上面是需要修改四處的根據自己的資訊來修改
app_ID 申請下來的 appid
app_KEY 申請下來的 appkey
redirect_URI 自己申請時候填寫的回撥地址 所以說
scope

我們一般的話第一個就可以 會獲取到qq的名稱性別和頭像，如果需要其他的話也可以自己去申請 。你自己有什麼許可權的你就可以早scope後面新增

到這裡我們的準備工作就準備好了，開始直接測試吧，
先測試一下自己的介面能不能用

<a href="<%=path%>/qq/QQlogin">請使用你的QQ賬號登陸</a> 
<a href="<%=path%>/qq/afterlogin">回撥的測試</a>

@RequestMapping("/qq/QQlogin")
    protected void doGet(HttpServletRequest request, HttpServletResponse response, Model model) throws IOException {
        response.setContentType("text/html;charset=utf-8");
        try {
           /* String authorizeURL = new Oauth().getAuthorizeURL(request);*/
            response.sendRedirect(new Oauth().getAuthorizeURL(request));
        } catch (QQConnectException e) {
            e.printStackTrace();
        }
    }

new Oauth().getAuthorizeURL(request) jar包提供的方法哦 會讀取你在qqconnectconfig.properties 裡面的資訊 然後拼接出來成一URL，具體是什麼樣的可以去官方文件去看，

授權的話就會進去自己在申請時候設定的回調了（redirect_URI）

 @RequestMapping("/qq/afterlogin")
        public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
            try {
                AccessToken accessTokenObj = (new Oauth()).getAccessTokenByRequest(request);
                String accessToken   = null,
                        openID        = null;
                long tokenExpireIn = 0L;
                if (accessTokenObj.getAccessToken().equals("")) {
                    System.out.print("沒有獲取到響應引數");
                }else{
                    accessToken = accessTokenObj.getAccessToken();
                    tokenExpireIn = accessTokenObj.getExpireIn();
                    OpenID openIDObj =  new OpenID(accessToken);
                    openID = openIDObj.getUserOpenID();
                    UserInfo qzoneUserInfo = new UserInfo(accessToken, openID);
                    UserInfoBean userInfoBean = qzoneUserInfo.getUserInfo();
                }
            }catch(Exception e){
                e.printStackTrace();
            }
            return null;
        }

謝謝！
