Python Alipay(支付宝) SDK with SHA1/SHA256 support

python-alipay-sdk

中文文档

Unofficial AliPay Python SDK

Taking a look at this guide if you are interested at the details on signing your order requests.

GUIDES

• Preparation
• Initialization & validation
• API
• Advanced API, introduced in 3.0

What's new in 3.0 and how to migrate to 3.0

3.0 introduced two new functions: client_api and server_appi as a replacement of old-styled function based api .

3.0 keeps backward compatibility with 2.*, The only thing you should keep in mind is Alipay.verify won't pop sign from data automatically, you should handle it by yourself.

Test

python -m unittest discover

Or you may do test manually in this way, debug=True will direct your request to sandbox environment:

alipay = AliPay(..., debug=True)

alipay's Issues

调试不过

你好，调试不过，是否可以发邮件给我，[email protected],涉及隐私信息，邮件比较好

cannot import name OSRNG

上传到服务器之后报错，
Exception Value:
cannot import name OSRNG
Exception Location:
/usr/local/lib/python2.7/dist-packages/alipay/init.py in , line 12

请问是否支持请求预生成二维码付款方式？

然后异步检测是否收款的

请问这个接口是需要和支付宝签约之后才能调用的吧？

请求参数为什么和官方方的SDK不一样？

另外我还有个问题。我注意到官方也出了一个SDK（然而目前并不好用），其中需要输入sub_merchant这个参数（商户ID），为什么你的库里面不需要这个信息呢？ 将来会不会出现接口不想容的问题呢？

项目依赖加密包pycrypto已经停止维护且不支持py3，建议使用pycryptodome, 他们之间的api是一样的！

亲自使用过，没有问题。

出现加密错误

生成的sign与网关验签字符串不对应

这是alipay返回的错误

调试错误，请回到请求来源地，重新发起请求。
错误代码 invalid-signature 错误原因: 验签出错，建议检查签名字符串或签名私钥与应用公钥是否匹配，网关生成的验签字符串为：app_id=2018062460380864&biz_content={out_trade_no:20161112,product_code:QUICK_WAP_PAY,total_amount:0.01,subject:subject}&charset=utf-8&method=alipay.trade.wap.pay&notify_url= http://www.getsms.club/&sign_type=RSA2&timestamp=2018-06-26 21:26:52&version=1.0

这是sdk生成的链接

https://openapi.alipay.com/gateway.do?app_id=2018062460380864&biz_content=%7B%22out_trade_no%22%3A%2220161112%22%2C%22product_code%22%3A%22QUICK_WAP_PAY%22%2C%22total_amount%22%3A0.01%2C%22subject%22%3A%22subject%22%7D&charset=utf-8&method=alipay.trade.wap.pay&notify_url=+http%3A%2F%2Fwww.getsms.club%2F&return_url=&sign_type=RSA2&timestamp=2018-06-26+21%3A26%3A52&version=1.0&sign=略

前者乱入了一些奇怪的amp;

同步验签

抱歉实在麻烦作者了，有个问题想问一下,
如果app直接把支付宝返回的结果交给网站来做同步验签，请问能否使用这个sdk来完成。样例如下:

{'sign_type': 'RSA2', 'sign': 'Iril1rkvl7KUifMM0j7LyTgSMW/XnwnK7kVfVN42Gtvv+2dWpOUvEY8PEXavAldQIyL6YPg074BJema3s3ineer53X61AeXEPfnz6uHQHjDYSYf1AVn/uOfsCtRxdWRDlV4rPsf4ARTPlPf4rcTEcyTbsviPKi/dAvsN3mo1yBfZH2KX2qw6VGOAAqeinMLDf78reCWyp8KHPMBl1+iPDa2Bzg8l2U0rD5p/C+p+3Ou8tLHOEa0p+agjM11Z585yxctA/DdTgVgkPL0YeSv4zz6A/GAzmySzi61M5Clf/mXib3VdZrseObPNDW4hKtvfFXhIgU1egFdpbOZD7CCGIw==', 'alipay_trade_app_pay_response': {'charset': 'utf-8', 'msg': 'Success', 'seller_id': '2088821540881344', 'timestamp': '2018-04-24 01:48:58', 'out_trade_no': 'CO_322_0_1524505548', 'auth_app_id': '2017111409922946', 'code': '10000', 'trade_no': '2018042421001004700254850965', 'app_id': '2017111409922946', 'total_amount': '39.00'}}

读取了alipay_trade_app_pay_response是一个字典

是否可以不使用文件

你好，证书信息是否可以直接存数据库，而不是文件，这样多用户时比较好处理，谢谢

ISV初始化错误

ISV初始化方法是没有支持app_private_key_string和alipay_public_key_string的吗，使用了Guide里面的样例，报TypeError: __init__() got an unexpected keyword argument 'app_private_key_srting'

是否考虑像Django一样从2.0开始只支持python3？

python3对中文的支持比较好，如果无需兼容python2的话，代码会优雅很多，更符合python之禅，所以建议完全迁移到py3

运行`python -m unittest discover` 报错 `FAILED (failures=2)`( test_sign_data_with_private_key_sha1和test_sign_data_with_private_key_sha256)

AliPayValidationError at alipay.fund.trans.toaccount.transfer

I run the examples on your document(thanks for this wonderful solution) and there is one point that I'm confuse about:

  File "/alipay/alipay/alipay/__init__.py", line 488, in api_alipay_fund_trans_toaccount_transfer
    raw_string, "alipay_fund_trans_toaccount_transfer_response"
  File "/alipay/alipay/alipay/__init__.py", line 524, in _verify_and_return_sync_response
    raise AliPayValidationError
alipay.alipay.exceptions.AliPayValidationError

When running the demo code of alipay.fund.trans.toaccount.transfer

I saw one issues about it but I think my key is right because I actually saw the transfer result success in the sandbox app.(It raise the error at verification)

Here is my code

app_private_key_path="/alipay/app_private_key.pem"
alipay_public_key_path="/alipay/alipay_pubilc_key.pem"

with open(app_private_key_path) as fp:
    app_private_key_string = open(app_private_key_path).read()#RSA.importKey(fp.read())

with open(alipay_public_key_path) as fp:
    alipay_public_key_string = open(alipay_public_key_path).read()#RSA.import_key(fp.read())

alipay = AliPay(
    appid="", # my code number which I didn't forget it
    app_notify_url="http://0.0.0.0:5000/", 
    app_private_key_string=app_private_key_string,
    alipay_public_key_string=alipay_public_key_string,
    sign_type="RSA2",
    debug=True, 
)

result = alipay.api_alipay_fund_trans_toaccount_transfer(
out_biz_no=datetime.now().strftime("%Y%m%d%H%M%S"),
payee_type="ALIPAY_LOGONID",
payee_account=person_acount,
amount=1.91,
        **{
            "payer_show_name":"test",
            # payee_real_name:"",
            "remark":"test",
        }
    )

the same error happens on alipay.fund.trans.order.query too.

没有这个接口 alipay.trade.order.settle(统一收单交易结算接口)

alipay.trade.order.settle(统一收单交易结算接口)
没有封装这个接口

无效的AppID参数

生成的 order_string 加 https://openapi.alipay.com/gateway.do? 后报错，无效的AppID参数

api_alipay_trade_query data return without sign

当我调用api_alipay_trade_query去查询订单信息的时候

阿里返回的数据里面没有Sign
{u'alipay_trade_query_response':
{u'msg': u'Invalid Arguments',
u'sub_code': u'isv.invalid-app-id',
u'code': u'40002',
u'sub_msg': u'\u65e0\u6548\u7684AppID\u53c2\u6570'}
}

所以_verify_and_return_sync_response
方法里面的
sign = response["sign"]
会报报KeyError: 'sign'

求解答。

这个APPID是可以用来下单的。我测试了一下网页下单。可以到支付宝去支付。
但是为什么查询的时候会说APPID不可用？？？？感觉也是很奇怪。。

为什么服务器签名后给客户端，客户端支付总是ALI38173错误

即时到账有密退款接口没有或者alipay.refund_web_order方法不兼容即时到账支付宝接口

即时到账退款的接口只有一个合作者身份ID，没有APPID，以及其余参数和refund_web_order也不同，接口走的是 https://mapi.alipay.com/gateway.do 。即时到账接口文档：

ISVAliPay中build_body函数调用父类build_body参数不对应

ISVAliPay中build_body函数
return super(ISVAliPay, self).build_body(method, biz_content, return_url, append_auth_token)
BaseAliPay类中build_body函数
def build_body(self, method, biz_content, return_url=None, notify_url=None, append_auth_token=False):

调用父类函数少了notify_url参数，代码参数错位，导致代码https://github.com/fzlee/alipay/blob/master/alipay/init.py#L155报错。

当我使用 alipay sdk 创建, alipay_fund_trans_toaccount_transfer 支付的时候
会报 alipay.exceptions.AliPayValidationError 的异常, 但是支付确实成功了. 支付宝同步接口验证签名的问题, 我这边一直没有解决, 你有没有好的解决方案呢?

签名无效

错误代码 invalid-signature 错误原因: 无效签名（我使用沙箱），已验证过，私钥签名的字符串公钥可以解密

wap支付的时候有bug

create_wap_trade方法里，biz_content最终并没有赋值，会造成跳转到支付宝支付时出现 ALI38173错误

网页支付。给出的例子运行之后报错如题。钱到是打过去了。请问一下这是什么问题？

有没有写支付宝小程序的方法

现在在开发支付宝小程序，只想获得用户信息，却不知道如何下手

大神你好，没有考虑过tornado的异步吗

could support tornado’s asynchronous feature?

签名验证问题 :)

Hello, 非常感谢你提供的这个支付宝 API SDK。学习了很多。
关于签名验证这块，支付宝文档 一节说只对返回的 xx_response 的内容进行校验。目前的代码中好像没有这种验证方式吧，不知道能不能帮忙看看。Thanks

交易预创建收不到异步消息

我在Alipay创建实例时设置了app_notify_url，但测试多次都未收到支付宝的异步通知，后来发现是由于代码在build_body方法if method in ()中未考虑"alipay.trade.precreate"的情况，所以新开了个issue，以便后面和我遇到同一情况的人可以参考一下。

web支付也有编码问题

如下：

证书无法读取

很奇怪，我这边无论是windows还是linux在调用verify_app_notify这个函数的时候都报下面那个错
"RSA key format is not supported"

跟进去看了下，错在__init__.py 121行key = RSA.importKey(fp.read()),查了下 因为我的privatekey是base64编码，而importKey接受二进制，要么key = RSA.importKey(b64decode(fp.read()))，要么 open的时候用"rb"模式，不然不可能能通过测试啊。。

无语的错误

verify 函数是不是已经考虑了解密验证？

想确认个小问题。在alipay.verify过程中是不是已经考虑了证书的验证，如此的话原则上如果返回成功就能够相信得到的信息。 因为在官方的说明里面强调了除了验证sign，还要验证其他所有的信息。这使得我有点不放心。(https://openclub.alipay.com/read.php?tid=1314&fid=69&ant_source=zsearch)

关于主页介绍中AliPay初始化的问题

在主页介绍中，app_notify_url设置为一个空的字符串，但是在实际测试中，如果不使用app_notify_url，那么一定要设置为None，不然就算是私钥和公钥设置好了，支付宝还是会提示验证签名失败

notify_url

报错：init() got an unexpected keyword argument 'notify_url'

api_alipay_trade_query 遇到错误

能否帮助解决一下

请问交易预创建(扫码支付)有返回二维码地址吗？

官方文档返回是：
"alipay_trade_precreate_response": {
"code": "10000",
"msg": "Success",
"out_trade_no": "6823789339978248",
"qr_code": "https://qr.alipay.com/bavh4wjlxf12tper3a"
},
"sign": "ERITJKEIJKJHKKKKKKKHJEREEEEEEEEEEE"
}

其中，qr_code用来生成二维码让客人扫码支付，我看咱们SDK的例程里面没有返回好像

我自己写的代码，“同步返回验签”总是通不过，不知 作者有么有时间帮忙指导下呢？

扫码付接口

自己实现的扫码付接口 https://github.com/wsqy/ALIPay
其中签名、 验签部分大量使用了你的项目中的代码 请多多批评

不能处理同步接口的错误

不能处理下面的报错

    "code": "40002",

交易查询 error

如例子中那样，alipay = AliPay(appid="", ...)，我直接运行
result = alipay.api_alipay_trade_query(out_trade_no='....')
print(result.get("trade_status", ""))

貌似支付宝更新支付接口了，需要签名

支付宝接口需要 “商户请求参数的签名串，详见签名“

是否在初始化时增加app_auth_token字段

是否在初始化时增加app_auth_token字段，这要ＩＳＶ即可以实现整个过程

支付宝工具生成的密钥字符串不能直接用吗？
