1、申請沙箱環(huán)境

#需要填一些個人信息
https://opendocs.alipay.com/

2、使用支付寶登入，并進(jìn)入控制臺，進(jìn)入'開發(fā)者工具推薦'-->'沙箱'

3、獲取基本信息

主要是APPID,和支付寶網(wǎng)關(guān)地址

4、生成應(yīng)用私鑰和應(yīng)用公鑰和支付寶公鑰

上面的接口加簽方式選擇系統(tǒng)默認(rèn)密鑰

注：這里有個坑，如果選擇自定密鑰，后面回調(diào)驗(yàn)簽會不成功。

點(diǎn)擊查看，可以看到應(yīng)用私鑰和應(yīng)用公鑰和支付寶公鑰

6、沙箱賬號

這里用商家和買家的賬號信息，也可以進(jìn)行充值

7、下載支付寶沙箱APP

8、在手機(jī)上用買家賬號和密碼登入登入支付寶沙箱APP

9、下載并安裝支付寶SDK

pip3 install alipay-sdk-python

10、生成支付鏈接

在視圖函數(shù)中調(diào)用止函數(shù)即可生成支付鏈接。
