Notification Validation

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 popped 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!'

And also an example for Django

def hello_world(request):
    # for django users
    data = request.dict()
    # for rest_framework users
    data = request.data

    signature = data.pop("sign")

    # verification
    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 into a dictionary called data
data = {
