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-8from ihome.base import dbfrom . import apifrom ihome.utils.commons import login_requiredfrom ihome.models import Orderfrom flask import g, current_app, jsonify, requestfrom ihome.utils.response_code import RETfrom alipay import AliPayfrom ihome import constants@api.route("/orders/<int:order_id>/payment", methods=["POST"])@login_requireddef 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”
