I can't find any official python alipay sdks so far, and it really pains a lot dealing with those sign methods. Hoping this libarary 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
- Transfer money to alipay account
- Query money transfer result
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.
pip install python-alipay-sdk --upgradeopenssl
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 from alipay import AliPay
alipay = AliPay(
appid="",
app_notify_url="",
app_private_key_path="",
alipay_public_key_path="" # alipay public key file path, do not put your public key file here
sign_type="RSA" # RSA or RSA2
debug=False # False by default
)Given a 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 = "alipay_" + 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)
# if you are using Python 2(you should really think about Python 3), making sure non-ascii strings are utf-8 encoded
subject = u"测试订单".encode("utf8")
# if you are Python3 user, just use the default string
subject = "测试订单"
# paid 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"
) # paid 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"
) # paid via App，just 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
)Once an order is paid, you will get a POST request from alipay servers which informs you that the order is paid
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()
signature = data.pop("sign")
print(json.dumps(data))
print(signature)
# verify
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 = {

signature = data.pop("sign")
success = alipay.verify(data, signature)
if success and data["trade_status"] in ("TRADE_SUCCESS", "TRADE_FINISHED" ):
print("trade succeed")alipay = AliPay(appid="", ...)
result = alipay.api_alipay_trade_pay(
out_trade_no="out_trade_no",

)
if result["code"] == "10000":

out_trade_no="out_trade_no",
total_amount=100
)
# check order status
paid = False
for i in range(10):
# check every 3s, and 10 times in all
print("now sleep 3s")
time.sleep(3)
result = alipay.api_alipay_trade_query(out_trade_no="out_trade_no")
if result.get("trade_status", "") == "TRADE_SUCCESS":
paid = True
break
print("not paid...")
# order is not paid in 30s , cancel this order
if paid is False:
alipay.api_alipay_trade_cancel(out_trade_no=out_trade_no)If you want to know what parameters are accepted, take a look into the official document
result = alipay.api_alipay_trade_refund(out_trade_no="xxx", refund_amount="xxx", ...)
if result["code"] == "10000":
print("success") # transfer money to alipay account
result = alipay.api_alipay_fund_trans_toaccount_transfer(
datetime.now().strftime("%Y%m%d%H%M%S"),
payee_type="ALIPAY_LOGONID/ALIPAY_USERID",
payee_account="[email protected]",
amount=3.12
)
result = {'code': '10000', 'msg': 'Success', 'order_id': '', 'out_biz_no': '', 'pay_date': '2017-06-26 14:36:25'} result = alipay.api_alipay_fund_trans_order_query(
out_biz_no="20170626152216"
)
print(result)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)
- John60676
- varwey
alipay.fund.trans.toaccount.transferandalipay.fund.trans.order.query
- return url missing for
alipay.trade.page.pay
- code refactoring, all functions are renamed
alipay.trade.page.payis used instead ofcreate_direct_pay_by_user- load key into memory, local key file access is needed for the 1st time
