向NSE选项链API发送请求的正确方式是什么？

Question

目前我有以下代码发送请求：

import requests

headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.1.1 Safari/605.1.15','Accept-Encoding': 'gzip, deflate, br','Accept-Language': 'en-US'}

url = "https://www.nseindia.com/api/option-chain-indices?symbol=NIFTY"

res = requests.get(url, headers = headers)

但当我执行最后一行时，它要么挂起很长时间，要么只给出401错误。 我尝试了标题的其他变体，但仍然没有得到正确的响应。 只要在浏览器中粘贴上面的url，就可以轻松地生成json对象。 另外，如果我从一个在线python工具中尝试上面的代码，有时会得到所需的o/p。这是否意味着只有当我将其托管在受信任的域或其他地方时，我才能使其工作

这应该起作用：

import requests
headers = {
    'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
    'Accept-Encoding':'gzip, deflate, br',
    'Connection':'keep-alive',
    'Cookie':'AKA_A2=A; ak_bmsc=2C30C88FD1C6BEED087CCD02E7643772~000000000000000000000000000000~YAAQPvASAr+cI2F6AQAAk6+tdQxncocfEFby+qeRnNu3MgRblj1MWVtVy+W1Stx/CNaRaf9PhfVoT568zV8qztByVrxV+WfdrCN2nXU0nToPdEoaZFeZ7irUu8aSUXcln/sou0taKkr1gjmS3f6faZs+Rv8LA32eUAtlTD+GgYL0OKTJ44qVVinDxeeaVOiLxzQaiv0YjRCLcovFhO7jVBCJhNeXzgOeUYCLjkOg+2DEnRaF1Cd85f83pkjjieOFpjvywz20ImVWy1fr+S2nEDqmcgKZdhjHPfJ76+Z3bvVB/Kyv2dH7J8BMjlVf7kxyGbmot54yxchJNEMs0A/QTkeow2Xa54IcGZo/RUxGRu90SFu6VpfcxLaVOdN9EbvhcNs//OPA1jhDm9Nf4A==; bm_sv=BB4B29FC4D88791AABD65B43FACB0AF7~ObLG1UzBN4vOInl5m0vWqjOpZUXtLDHJDxr92uXdHHp5bjKjrEMMJcJRzS5VY5lkIs3N7JH+gZtoTnYIWKFqPZFhFC8Oo+sjmZLrin4taKkPfpvp7RdbqySQh6BLQwbWg3UgQJUQN29H0q9MJN6FuaW2b2i13zn5CmZUSDSpJVo=',
