python请求中这个凭证站点的正确头/负载是什么？

Question

我正在设置一个python脚本，检查凭证代码是否仍然有效。 （站点为：“https://www.lieferando.de/checkVoucher.php”）

我在Postman和ARC中工作，但是我不能让它处理Python请求。我也试过邮递员的create code函数，但仍然不起作用。你知道吗

url = "https://www.lieferando.de/checkVoucher.php"

payload = {'vouchercode': "TRF5RCF6VRLZ7552"}
headers = {
    'vouchercode': "TRF5RCF6VRLZ7552",
    'Content-Type': "application/x-www-form-urlencoded",

    }

response = requests.request("POST", url, data=payload, headers=headers)

print(response.text)

服务器应响应

{"basketResponse":null,"status":"error","value":"Alle Gutscheine mit diesem Gutscheincode wurden bereits verwendet. Es sind keine Gutscheine verf\u00fcgbar und somit ist der Code nicht mehr g\u00fcltig."

但回应是

{"basketResponse":null,"status":"error","value":"Bitte gib den Gutscheincode ein","markfields":["ivouchercode"]}

Answer 1

所以你的代码有几个问题：

1. 您应该将payload作为JSON字符串发送（因此将data=替换为json=）

2. 您使用的headers不正确

3. 您应该在POST请求中包含cookies（您可以使用requests.session()自动完成）

总之，您的代码应该如下所示：

import requests

session = requests.session()

url = "https://www.lieferando.de/checkVoucher.php"

headers = {"User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:66.0) Gecko/20100101 Firefox/66.0", "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8", "Accept-Language": "en-US,en;q=0.5", "Accept-Encoding": "gzip, deflate", "DNT": "1", "Connection": "close", "Upgrade-Insecure-Requests": "1"}
session.request("GET", "https://www.lieferando.de/bestellung-abschliessen-miran-pizza-doener", headers=headers)

payload = {'vouchercode': "TRF5RCF6VRLZ7552"}
response = session.request("POST", url, json=payload, headers=headers)

print(response.json())

（附言： response.json()将response转换为JSON字符串，这使其更易于使用。如果不需要，您可以改用.text）

希望这有帮助
