支付宝支付
一、支付宝支付：沙箱测试环境
支付宝支付
a. 去支付宝申请
- 正式：营业执照
- 测试：沙箱测试环境 https://openhome.alipay.com/platform/appDaily.htm?tab=info
https://open.alipay.com/platform/homeRoleSelection.htm
开发者中心，研发服务，沙箱环境。。。
下载沙箱APP.作为测试得支付宝；
APPID:
2016091700535390
买家：
买家账号 jtyapr6187@sandbox.com
登录密码 111111
支付密码 111111
二、生成公钥，私钥
b. 开发程序
SDK
- 官方
- github
utils/pay.py
依赖：pip3 install pycryptodome
公钥私钥：用公钥加密数据，用私钥来解密数据
- 应用公钥
- 支付宝公钥
- 应用私钥
三、测试支付
用之前，下载好得沙箱环境得app，里面可以设置账户余额，扫码，支付
即：
买家：
买家账号 jtyapr6187@sandbox.com
登录密码 111111
支付密码 111111
支付成功，返回到商户界面时，需要校验是否是阿里得 签名！！！
支付成功，阿里返回得数据：
{'charset': 'utf-8', 'out_trade_no': 'x21533095384.3803577', 'method': 'alipay.trade.page.pay.return', 'total_amount': '100.00', 'sign': 'I4AYXuDOt7kzQuzCu8sAQptRjbQQXamBJDCArQ+2NSy4JpuA0QM06/82SwHwglT4vVgv8xMP1U6UXYP3+1/A1lNuyAwUa0gp/C3XAa8W19vaQucR/VQUJi5MCXtMx5BG07MviepyBlwdud0YpScfTlmY2cNum0Kc02nD/icFJQwEM0+6sPzKTAeuJz21poX3HqFnJAfTSktocvLYqLj4QLoopGbzvzQ+vp70r1Cp5OX7QaZkwDtD8lpRSymNEntu6nr/4V5iJ6iE0J55W7kwfIOJfWymkCtKE1mo0NBVe9CslsA1HnWYkW+fQBgq9tl5+fGxG0JYlz1TiGchfSFc/Q==', 'trade_no': '2018080121001004080200706519', 'auth_app_id': '2016091700535390', 'version': '1.0', 'app_id': '2016091700535390', 'sign_type': 'RSA2', 'seller_id': '2088102176095872', 'timestamp': '2018-08-01 11:50:16'}
订单状态修改：
中间有一个环节：支付成功，校验是否完成，修改订单状态，返回商家页面，
app_notify_url=settings.NOTIFY_URL, # 如果支付成功，支付宝会向这个地址发送POST请求（校验是否支付已经完成）
return_url=settings.RETURN_URL, # 如果支付成功，重定向回到你的网站的地址。
# 支付相关配置
APPID = "2016091700535390"
NOTIFY_URL = "http://10.0.0.200/update_order/" # 得是公网ip 阿里返回得只能是 公网；
RETURN_URL = "http://127.0.0.1:8000/pay_result/"
PUB_KEY_PATH = "keys/alipay_public_2048.txt"
PRI_KEY_PATH = "keys/app_private_2048.txt"
四、代码copy到服务器运行
只有公网ip，才能让支付宝找到，调用函数，校验：是否是阿里得签名，才能修改订单得状态；
五、code
https://github.com/alice-bj/alipay
settings.py
# 支付相关配置 APPID = "2016091700535390" NOTIFY_URL = "http://10.0.0.200:8000/update_order/" # 得是公网ip RETURN_URL = "http://10.0.0.200:8000/pay_result/" PUB_KEY_PATH = "keys/alipay_public_2048.txt" PRI_KEY_PATH = "keys/app_private_2048.txt"

六、总结
支付
- rsa 加密
- 商户私钥+支付宝公钥
- 精度，小数点后2位
- 宕机，程序需要返回success，否则支付宝一天一直会发
申请：
a. 去支付宝申请 - 正式：营业执照 - 测试：沙箱测试环境 https://openhome.alipay.com/platform/appDaily.htm?tab=info 开发者中心，研发服务，沙箱环境。。。 下载沙箱APP.作为测试得支付宝； APPID: 2016091700535390 买家： 买家账号 jtyapr6187@sandbox.com 登录密码 111111 支付密码 111111 b. 开发程序 SDK - 官方 - github utils/pay.py 依赖：pip3 install pycryptodome 公钥私钥：用公钥加密数据，用私钥来解密数据 - 应用公钥 - 支付宝公钥 - 应用私钥
开发：
1. 引入一个sdk(AliPay) 需要对 商品价格 加密
2. 需要用：
APPID、
支付成功发得post请求（修改订单得状态）地址、
支付成功，重定向得网站地址、
支付宝得公钥、
商家得私钥、
obj = AliPay(
appid=settings.APPID,
app_notify_url=settings.NOTIFY_URL, # 如果支付成功，支付宝会向这个地址发送POST请求（校验是否支付已经完成）
return_url=settings.RETURN_URL, # 如果支付成功，重定向回到你的网站的地址。
alipay_public_key_path=settings.PUB_KEY_PATH, # 支付宝公钥
app_private_key_path=settings.PRI_KEY_PATH, # 应用私钥
debug=True, # 默认False,
)
3. 实例化AliPay对象后，对商品，价格加密后，就可以跳转到二维码得支付页面
query_params = alipay.direct_pay(
subject="购买得商品，衣服", # 商品简单描述
out_trade_no= out_trade_no, # 商户订单号
total_amount=money, # 交易金额(单位: 元 保留俩位小数)
)
pay_url = "https://openapi.alipaydev.com/gateway.do?{}".format(query_params)
4. 支付成功，跳转回的页面，验证阿里得签名
def pay_result(request):
"""
支付完成后，跳转回的地址
:param request:
:return:
"""
params = request.GET.dict()
sign = params.pop('sign', None)
alipay = aliPay()
status = alipay.verify(params, sign) # 校验是否是 阿里得 签名
if status:
return HttpResponse('支付成功')
return HttpResponse('支付失败')
5. 支付之后，阿里会发一个post请求，我们可以修改订单状态，验证阿里得签名（这个得在公网ip下，阿里得能找到）
@csrf_exempt
def update_order(request):
"""
支付成功后，支付宝向该地址发送的POST请求（用于修改订单状态）
:param request:
:return:
"""
if request.method == 'POST':
from urllib.parse import parse_qs
body_str = request.body.decode('utf-8')
post_data = parse_qs(body_str)
post_dict = {}
for k, v in post_data.items():
post_dict[k] = v[0]
alipay = aliPay()
sign = post_dict.pop('sign', None)
status = alipay.verify(post_dict, sign)
if status:
# 修改订单状态
out_trade_no = post_dict.get('out_trade_no')
print(out_trade_no)
# 2. 根据订单号将数据库中的数据进行更新
return HttpResponse('支付成功')
else:
return HttpResponse('支付失败')
