1.Oauth（開放授權(quán)）是一個(gè)開放標(biāo)準(zhǔn)，允許用戶讓第三方應(yīng)用訪問該用戶在某一網(wǎng)站上存儲(chǔ)的私密資源（如照片，視頻，聯(lián)系人列表），而無需將用戶名和密碼提供給第三方

關(guān)鍵字：appKey appSecret token(令牌)

2.SSO授權(quán)

如果本地手機(jī)裝有微博客戶端，則直接跳轉(zhuǎn)到微博客戶端，只需點(diǎn)擊授權(quán)按鈕，就可以登陸了 

qq第三方登陸使用Oauth2.0實(shí)現(xiàn)，測試代碼

點(diǎn)擊下面的連接

https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=101334262&redirect_uri=http://www.qingguow.cn/sso.php
