準備工作

首先需要註冊成為螞蟻金服的開發者

    https://openhome.alipay.com/platform/manageHome.htm

接著就是下載支付寶的祕鑰生成工具。

RSA簽名驗籤工具windows_V1.4

教程支付寶的官方文件已經寫的很詳細了：https://docs.open.alipay.com/291/105971

這裡我們選擇PKCS1，非java版的

儲存好你的公鑰和私鑰

然後將應用公鑰貼上到支付寶頁面

下面的應用閘道器什麼的是選填，具體使用方法看官方文件，沒有比那個還詳細的了。

點選左上角的沙箱賬號和沙箱應用，下載你的沙箱版支付寶，用於測試使用。使用沙箱賬號登入。

接下來開始安裝支付寶的SDK

下載支付寶的SDK：https://pypi.org/project/alipay-sdk-python/#files

 我尋思著解壓後你會得到兩個檔案，一個安裝不上就安裝另一個吧。

安裝命令，（有虛擬環境的就進入到你的虛擬環境中）：

pip install [F:\.......]替換成你的檔案路徑，記得加檔名。切記路徑中不要包含空格。

我尋思著你哪個也安裝不上，會提示你編譯錯誤。

你也可以試試官方的安裝命令：pip install alipay-sdk-python

不行的話就按我的來吧。

先安裝pycrypto：pip install pycrypto   

下載到本地安裝也行。 網址：https://pypi.org/project/pycrypto/#files

再安裝支付寶SDK：pip install [F:\.......]替換成你的檔案路徑。推薦安裝cp36

這是編譯安裝，會比較慢。

到這裡準備工作算是結束了。

開始動手

第一步：檢視官方文件

地址：https://pypi.org/project/alipay-sdk-python/#description

這裡我就給例程全部貼上過來了。選取你想用的即可。

記得把所有的import全部貼上過去，最後我們再刪掉灰色的就好。
