開發之前

需求：網站接入qq,sina微博登錄，本文最后付效果圖：

說明：大部分網站本身是需要用戶概念的，很多操作依附于用戶，而qq或微博作為一種登錄方式指向用戶而已，我參考了一下其他網站的做法，

一般有如下兩種做法：

1，強制綁定：用戶第一次通過qq登錄時必須與該網站賬戶綁定，也就是用戶必須要先有一個此網站賬戶才能登錄成功

2，互相獨立，用戶第一次通過qq登錄時直接重新為用戶注冊一個賬戶，如以用戶名為qq_123456直接注冊一個賬戶，與其他賬戶無關；

?

站在用戶角度考慮下，可能需要更多的選擇性，因此我是如下考慮的:

用戶登錄后在個人中心中也可設置綁定。

文檔說明

現在大部分第三方的登錄OAuth2.0為標準，所以開發流程基本都一致，一般都是一下步驟：

1，申請接入，獲取appid&appkey（接入后又第三方發放）

2，用戶登錄第三方下發token，

3，通過token獲取用戶唯一標示，一般是一個openId

api地址：

qq:http://wiki.connect.qq.com/api列表

sina：http://open.weibo.com/wiki/授權機制

qq&sina也提供了java sdk

http://qzonestyle.gtimg.cn/qzone/vas/opensns/res/doc/qqConnect_Server_SDK_java_v2.0.zip

sina的雖然開源了，但里面很多代碼寫的有問題，用的之后需要注意

開發

數據結構方面需要加以一張表用來維護登錄方式和用戶關聯（通過openId以及登錄方式確定唯一性）

網站引入，appid,appkey,回調地址的配置有不再贅述了

代碼基本上參照sdk中的demo就可以了，

簡單貼一下controller（springMVC架構）中的代碼吧

AUthController為父類，存放一些第三方登錄的通用方法，BindController為用戶綁定提供方法，第三方登錄的controller基本上就是一個登錄跳轉方法，一個回調方法，以及一些接口api的調用

頁面效果

注：該流程為用戶首次使用第三方登錄時流程

1,登錄頁面放置第三方登錄圖標

2，點擊圖標接入第三方接口，可跳轉至第三方登錄界面

3，第三方登錄完成，用戶賬戶綁定

4，用戶登錄后，可在個人設置中管理第三方登錄的綁定
