业务场景：实现租房小程序，用户下单和订单保存功能

1、安装以下包：

pip install python-alipay-sdk --upgrade

2、flask实现

# coding:utf-8 from ihome.base import db from . import api from ihome.utils.commons import login_required from ihome.models import order from flask import g, current_app, jsonify, request from ihome.utils.response_code import RET from alipay import AliPay from ihome import constants @api.route("/orders/<int:order_id>/payment", methods=["POST"]) @login_required def order_pay(order_id): """发起支付宝支付""" user_id = g.user_id try: order = Order.query.filter(Order.id == order_id, Order.user_id == user_id, Order.status == "WAIT_PAYMENT").first_or_404() except Exception as e: current_app.logger.error(e) return jsonify(errno=RET.DBERR, errmsg="数据库异常") if order is None: return jsonify(errno=RET.NODATA, errmsg="订单数据有误") app_private_key_string = open(r"D:\ihome\v1\keys\app_private_key.pem").read() alipay_public_key_string = open(r"D:\ihome\v1\keys\alipay_public_key.pem").read() alipay = AliPay( appid="你的appid", app_notify_url=None, app_private_key_string=app_private_key_string, alipay_public_key_string=alipay_public_key_string, sign_type="RSA2", debug=False ) order_string = alipay.api_alipay_trade_wap_pay( out_trade_no=order.id, total_amount=str(order.amount/100.0), subject="爱家 %s" % order.id, return_url="http://127.0.0.1:8000/payComplete.html", notify_url=None ) pay_url = constants.ALIPAY_URL_PREFIX order_string return jsonify(errno=RET.OK, errmsg="OK", data={"pay_url": pay_url}) @api.route("/order/payment", methods=["PUT"]) def save_order_payment_result(): """保存订单支付结果""" data = request.form.to_dict() # sign must be poped out signature = data.pop("sign") app_private_key_string = open(r"D:\ihome\v1\keys\app_private_key.pem").read() alipay_public_key_string = open(r"D:\ihome\ihome\v1\keys\alipay_public_key.pem").read() alipay = AliPay( appid="你的appid", app_notify_url=None, app_private_key_string=app_private_key_string, alipay_public_key_string=alipay_public_key_string, sign_type="RSA2", debug=False ) success = alipay.verify(data, signature) if success: order_id = data.get("out_trade_no") trade_no = data.get("trade_no") try: with db.auto_commit(): order = Order.query.get(order_id) order.status = "WAIT_COMMENT" order.trade_no = trade_no db.session.add(order) print('更新成功！') except Exception as e: current_app.logger.error(e) return jsonify(errno=RET.OK, errmsg="OK")

3、遇到问题

①在支付测试中，记得保证每次的out_trade_no不同（使用时间戳），如果重复会报“操作频繁，请稍后重试”
