php 支付寶 SDK 單筆轉賬

支付寶單筆轉賬,記錄下使用過程和一些碰到的問題,以便為同樣需求的提供一些參考.

官方的一些文件:單筆轉賬 , SDK,如何生成及配置公鑰證照(視訊),公鑰證照

上面差不多是準備的工作,配置好後把三個正式都下載下來,這裡可能有一些用錯檔案的情況

下載後的檔名稱

SDK裡面已經寫了一個例子,這裡貼出來

這裡需要注意兩個地方
使用證照模式本地必須開始SSL
如果出現SSL certificate: unable to get local issuer certificate錯誤資訊
解決辦法：到 curl.haxx.se/ca/cacert.pem 下載pem檔案，並將檔案拷貝到如下路徑(根據自己的實際情況),並在php.ini 增加
curl.cainfo =”E:/wamp64/bin/php/php7.0.10/extras/ssl/cacert.pem”

另外一個就是這個SDK 的alipaySDK中定義的Encrypt()/Decrypt()函式與Laravel中定義的Encrypt()/Decrypt()函式重名了。這裡在檔案中查詢encrypt/decrypt替換為alipayEncrypt/alipayDecrypt即可。
