为什么URL从Postman而不是Python返回响应?

我试图从这个URL中提取数据。它在Postman中工作,但在Python(3.8)中不工作。连接关闭,没有响应。我也尝试手动传递我的浏览器cookie,但得到了相同的结果。
下面是将XHR响应复制为cURL(bash)后,Postman生成的代码

import requests

url = "https://www.cmegroup.com/CmeWS/mvc/Settlements/Futures/Settlements/10047/FUT?tradeDate=10/07/2022"

payload={}
headers = {
  'Cookie': 'ak_bmsc=40201F1BC4FD8456EED03A38A16CBC95~000000000000000000000000000000~YAAQj2V0aGgBgqeDAQAAPzYKsxFH4BM3CXIxGLs0BpfFzUiVR7t+Ul6Q9U64ItnBxPPhosD8CEBZ03QGfv4XHioHnh1Hzn3E0Kc17EV4dAMLsUySAsUwh3Q+MD9zf5gNh4nCZXkoP+ChCHkYJ+uR1qxnPRZK8yu4USf8by8Js6LcoO3X2WPWkHw5LAsBcImL5hdhYDCX9n2bS3j/vHRyT2cg6iE0YLrAK6eLwgp6w8EFN9JhRKyL8AGYcYEJm6Rxk2EFQ62cG12uSW5pSl/h5yF/Z5qF8+0xXi3yhcBZ9vEvz9W8YPw9gbreYAvURg4wZtkxtxJyBkgfwlGkbc+NnzcErzlmH2b9ZYjs+vuP3GK0zP/c1e3BKgVEz/iQ; bm_sv=4E1D62DAE9E148686F96340796FD4A79~YAAQj2V0aDr/hKeDAQAAuChCsxGk32eAruqs2a29BNi48QW5E1rqQqbyowotXKQ1+hoMqvIsxi/uXHUQ+csp+U4/P6dMDker8yWYw80MxnzYfQ0k1UMD4VtKUGthUwGgBHrP42vpUbUMkVXVgjJh6OQrEwEFyP9T/wZGi8HraSMtkUJ2fmySYJtHS5Hvxr5oGlv9RtG2zlsq30gBxaJI1Y/j5HTh1hIKLsmI/VmrrTU9kI3M4zgoAF+TU8C1tWGG8bhr~1'
}

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

print(response.text)

编辑:我不得不修改cURL,因为我在将它导入Postman时遇到了错误。这是我在Postman中使用的cURL(bash),它返回了正确的响应:

curl 'https://www.cmegroup.com/CmeWS/mvc/Settlements/Futures/Settlements/10047/FUT?strategy=DEFAULT&tradeDate=10/07/2022&pageSize=500&isProtected&_t=1665158458937' \

有什么想法如何修复请求吗?其他SO线程似乎都没有答案。

您需要提供User-Agent头,这实际上就是您需要的URL

import requests

AGENT = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.0 Safari/605.1.15'
URL = "https://www.cmegroup.com/CmeWS/mvc/Settlements/Futures/Settlements/10047/FUT?tradeDate=10/07/2022"
headers = {'User-Agent': AGENT}

(r := requests.get(URL, headers=headers)).raise_for_status()
print(r.json())
