I can't find any official python alipay sdks so far, and it really pains a lot dealing with those sign methods. Hoping this library could do some help :).
So far, the following functions are supported:
- Pay via Web
- Pay via WAP
- Pay via App
- Verification
- Face to face trade
- Precreate trade
- Query trade
- Cancel trade
- Refund
- Query refund result
- Order Settlement
- Transfer money to alipay account
- Query money transfer result
- ISV integration/Get app_auth_code by app_auth_token
- ISV integration/Query authorized apps
Taking a look at this guide if you are interested at the details on signing your order requests. Or you may just follow this manual if not.
# installation
pip install python-alipay-sdk --upgrade
# openssl
OpenSSL> genrsa -out app_private_key.pem 2048 # the private key file
OpenSSL> rsa -in app_private_key.pem -pubout -out app_public_key.pem # export public key
OpenSSL> exit
The public key we download from open.alipay.com is a string, which cannot be recognied by this lib directly, making sure it's surrounded with -----BEGIN PUBLIC KEY-----
and -----END PUBLIC KEY-----
There is also an example for your reference
from alipay import AliPay, ISVAliPay
# Making sure your key file is adhered to standards.
# you may find examples at tests/certs/ali/ali_private_key.pem
app_private_key_string = open("/path/to/your/private/key.pem").read()
alipay_public_key_string = open("/path/to/alipay/public/key.pem").read()
app_private_key_string = """
-----BEGIN RSA PRIVATE KEY-----
base64 encoded content
-----END RSA PRIVATE KEY-----
"""
alipay_public_key_string = """
-----BEGIN PUBLIC KEY-----
base64 encoded content
-----END PUBLIC KEY-----
"""
alipay = AliPay(
appid="",
app_notify_url=None, # the default notify path
app_private_key_string=app_private_key_string,
# alipay public key, do not use your own public key!
alipay_public_key_string=alipay_public_key_string,
sign_type="RSA" # RSA or RSA2
debug=False # False by default
)
# Forget about what I mentioned below if you don't know what ISV is
# either app_auth_code or app_auth_token should not be None
isv_alipay = ISVAliPay(
appid="",
app_notify_url=None, # the default notify path
app_private_key_string="",
# alipay public key, do not use your own public key!
alipay_public_key_string=alipay_public_key_string,
sign_type="RSA" # RSA or RSA2
debug=False # False by default,
app_auth_code=None,
app_auth_token=None
)
Given an alipay function, say alipay.trade.page.pay
, we will defind a corresponding function alipay.api_alipay_trade_page_pay()
Generally we will do such a translation:
function_name = "api_" + alipay_function_name.replace(".", "_")
According to alipay document, some paremeters in biz_content
are optional and some are not.
We defind functions in this way so that you can put those optional parameters in kwargs
:
def api_alipay_xxx(self, out_trade, total_amount, **kwargs):
...
biz_content.update(kwargs)
# For Python 2 users(you should really think about Python 3),
# making sure non-ascii strings are utf-8 encoded
subject = u"测试订单".encode("utf8")
# For Python 3 users, just use the default string
subject = "测试订单"
# Pay via Web,open this url in your browser: https://openapi.alipay.com/gateway.do? + order_string
order_string = alipay.api_alipay_trade_page_pay (
out_trade_no="20161112",
total_amount=0.01,
subject=subject,
return_url="https://example.com",
notify_url="https://example.com/notify" # this is optional
)
# Pay via WAP, open this url in your browser: https://openapi.alipay.com/gateway.do? + order_string
order_string = alipay.api_alipay_trade_wap_pay(
out_trade_no="20161112",
total_amount=0.01,
subject=subject,
return_url="http://example.com",
notify_url="https://example.com/notify" # this is optional
)
# Pay via App,just pass order_string to your Android or iOS client
order_string = alipay.api_alipay_trade_app_pay(
out_trade_no="20161112",
total_amount=0.01,
subject=subject,
notify_url="https://example.com/notify" # this is optional
)
Once an order is paid, a POST request will be sent to tell you the information
Here is a simple example for flask web server:
import json
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/', methods=["GET", "POST"])
def hello_world():
data = request.form.to_dict()
# sign must be poped out
signature = data.pop("sign")
print(json.dumps(data))
print(signature)
# verify
success = alipay.verify(data, signature)
if success and data["trade_status"] in ("TRADE_SUCCESS", "TRADE_FINISHED" ):
print("trade succeed")
return 'Hello, World!'
Here is a more general example for verification
# gathering all parameters sent from alipay server, and put them in a dictionary called data
data = {

Go through the details before you do anything, or it may pains.

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.trade.order.settle
- Do encryption/decryption with
pycryptodomex
,which has not conflict with Pycrypto (many thanks to fakepoet)
- initialize Alipay instance with key string
- bug fix for
ISVAlipay.build_body
.
alipay.trade.fastpay.refund.query
Query refund result.
- bug fix for
api_alipay_trade_precreate
, notify url is not included in request params.
- change dependence from pycrypto to pycryptodome. for users upgraded from 1.3.0, uninstall pycrypto first
- allow notify_url be overriden in hose 4 functions:
alipay.trade.wap.pay
alipay_trade_app_pay
alipay.trade.page.pay
alipay.trade.pay
- ISV integration
alipay.fund.trans.toaccount.transfer
andalipay.fund.trans.order.query
- return url missing for
alipay.trade.page.pay
- code refactoring, all functions are renamed
alipay.trade.page.pay
is used instead ofcreate_direct_pay_by_user
- load key into memory, local key file access is needed for the 1st time
