1. 下載SDK

我使用的是 PHP版本的 ，你們根據需要下載對應的

2. 解壓包到對應目錄

3. 在程式中 引入包檔案 AopSdk.php 並初始化

貼上部分程式碼：（基於CI 框架）

【注意】

 【2】網頁授權私鑰來自 軟體生成的 rsa_private_key.pem 不是 rsa_private_key_pkcs8.pem
    且私鑰字串拷貝出來 去掉頭尾 和 換行符

 【3】網頁授權 不能用沙箱 app 來掃取 正式地址，否則會一直跳轉

 【4】使用 auth_userinfo 獲取到的userId 與 支付生成的 buyerId 不是同一個，而與靜默授權 auth_base 取到的
   userId 是同一個，所以 建議使用靜默授權，反正支付寶網頁授權獲取使用者資訊，文件有點奇葩，說好的非靜默授權能獲取到使用者的暱稱和頭像，結果一個木有獲取到，問客服，客服說文件僅供參考，我就呵呵了。。。
