一. python-alipay-sdk 安装下载:
卸载pycrypto(如有)
pip uninstall pycrypto
安装python-alipay-sdk
pip install python-alipay-sdk
二.生成密钥文件
1. 使用OpenSSL
openssl
2. 生成私钥
genrsa -out app_private_key.pem 2048
3. 生成公钥
rsa -in app_private_key.pem -pubout -out app_public_key.pem
4. 退出OpenSSL
exit
三.登录支付宝绑定己方公钥, 获取后方公钥(沙箱):
https://sandbox.alipaydev.com/user/accountDetails.htm?currentBar=1
四.初始化:
项目文件中,定位己方私钥和以及他方公钥,并进行初始化.
import os from alipay import AliPay from django.conf import settings # 进行alipay初始化 # 配置地址 private_path = os.path.join(settings.BASE_DIR, ‘apps/order/app_private_key.pem‘) public_path = os.path.join(settings.BASE_DIR, ‘apps/order/alipay_public_key.pem‘) # 获取公私钥字符串 app_private_key_string = open(private_path).read() alipay_public_key_string = open(public_path).read() alipay = AliPay( appid="2016101100664228", app_notify_url=None, # 默认回调url app_private_key_string=app_private_key_string, alipay_public_key_string=alipay_public_key_string, sign_type="RSA2", debug=True, # 上线则改为False , 沙箱True )
五.使用:
# 调用接口(传参订单号和总价,标题) order_string = alipay.api_alipay_trade_page_pay( out_trade_no=order_id, total_amount=str(total_pay), subject=‘支付订单:%s‘ % order_id, return_url=None, notify_url=None, ) # 拼接应答地址 pay_url = ‘https://openapi.alipaydev.com/gateway.do?‘ + order_string
返回应答pay_url即可.
Python使用SDK(python-alipay-sdk) 与支付宝API对接
