支付宝接口的二次封装

安装alipay的sdk安装

pip install python-alipay-sdk

支付宝沙箱环境

应用公私钥生成器下载

alipay的github地址

在项目的libs下新建一个ali_pay的包

# 新建pay.py文件

from alipay import AliPay

from . import settings

# alipay实例
alipay = AliPay(
    appid=settings.APPID,
    app_notify_url=None,
    app_private_key_string=settings.APP_PRIVATE_KEY_STRING,
    alipay_public_key_string=settings.ALIPAY_PUBLIC_KEY_STRING,
    sign_type=settings.SIGN_TYPE,
    debug=settings.DEBUG
)

# 支付宝网关接口
gateway = settings.GATEWAY

alipay的配置文件settings.py

import os


def obtain_key(key_store_path):
    with open(key_store_path, mode='r', encoding='utf-8') as fr:
        key = fr.read()
    return key


# 应用的ID号
APPID = "2021000116664633"

# 应用私钥&支付宝的公钥
APP_PRIVATE_KEY_STRING_PATH = os.path.join(os.path.dirname(__file__), 'key', 'private_key.pem')
ALIPAY_PUBLIC_KEY_STRING_PATH = os.path.join(os.path.dirname(__file__), 'key', 'public_key.pem')
APP_PRIVATE_KEY_STRING = obtain_key(APP_PRIVATE_KEY_STRING_PATH)
ALIPAY_PUBLIC_KEY_STRING = obtain_key(ALIPAY_PUBLIC_KEY_STRING_PATH)

# 签名类型
SIGN_TYPE = 'RSA2'

# 是否启用沙箱测试环境
DEBUG = True  # False则启用正式环境

# 支付宝网关接口
GATEWAY = "https://openapi.alipaydev.com/gateway.do?" if DEBUG else "https://openapi.alipay.com/gateway.do?"

封装:

`__init__.py`

from .pay import alipay, gateway

# 外部使用方式
from ali_pay import alipay,gateway
