Crypto支付宝模块的安装

沙箱环境地址：https://openhome.alipay.com/platform/appDaily.htm?tab=info

1.将Crypto放到site-packages下

2、OSError:Cannot load native module 'Crypto.Cipher._raw_ecb':Trying '_raw_ecb.cp36-win_amd64.pyd':cannot load library 'C:UsersadminAppDataLocalTemp\_MEI160382CryptoUtil..Cipher\_raw_ecb.cp36-win_amb64.pyd'：这个问题卡了我很久，前前后后尝试了很多中方法，粘出其中两种的链接

https://github.com/Legrandin/pycryptodome/issues/155

https://github.com/pyinstaller/pyinstaller/issues/2881

最后经过多次尝试和查找资料发现 Crypto对应的是pycryptodome包，所以出现这个问题。具体操作为pip list 查看当前安装包中是否有pycryptodome包，若有 则pip uninstall pycryptodome，卸载pycryptodome包，安装原包 pip install pycrypto(若失败使用 conda install pycrypto)。

3.pip install Crypto

4.生成支付配置实例

    def ali(self):

        # 沙箱环境地址：https://openhome.alipay.com/platform/appDaily.htm?tab=info
        app_id = "2016092000558535"
        # POST请求，用于最后的检测
        notify_url = "http://182.61.36.131:8000/page2/"
        # notify_url = "http://www.wupeiqi.com:8804/page2/"
        # GET请求，用于页面的跳转展示
        return_url = "http://182.61.36.131:8000/page2/"
        # return_url = "http://www.wupeiqi.com:8804/page2/"
        merchant_private_key_path = "keys/应用私钥2048.txt"
        alipay_public_key_path = "keys/myalipay_public_2048.txt"
        alipay = AliPay(
            appid=app_id,
            app_notify_url=notify_url,
            return_url=return_url,
            app_private_key_path=merchant_private_key_path,
            alipay_public_key_path=alipay_public_key_path,  # 支付宝的公钥，验证支付宝回传消息使用，不是你自己的公钥
            debug=True,  # 默认False,
        )
        return alipay

5.调用支付宝接口URL

 subject = request.data.get('subject')
            alipay = self.ali()
            # 生成支付的url
            query_params = alipay.direct_pay(
                subject=subject,  # 商品简单描述
                out_trade_no="x2" + str(time.time()),  # 商户订单号
                total_amount=final_price,  # 交易金额(单位: 元 保留俩位小数)
            )
            pay_url = "https://openapi.alipaydev.com/gateway.do?{}".format(query_params)
            res.data = pay_url
