Question

基本上，我正在尝试删除此链接https://www.nseindia.com/live_market/dynaContent/live_watch/option_chain/optionKeys.jsp?segmentLink=17&instrument=OPTIDX&symbol=BANKNIFTY

这应该很容易吧？

import requests

headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36'}

payload = requests.get('https://www.nseindia.com/live_market/dynaContent/live_watch/option_chain/optionKeys.jsp?segmentLink=17&instrument=OPTIDX&symbol=BANKNIFTY',headers=headers)
print(payload.content)

它曾经只是一个经典的python请求示例，但他们已经开始检查少量指标。

因此，我遵循了如下所示的方法How to programmatically replicate a request found in Chrome Developer Tools?

并导致

import requests
import pandas as pd

headers = {
    'Connection': 'keep-alive',
    'Cache-Control': 'max-age=0',
    'DNT': '1',
    'Upgrade-Insecure-Requests': '1',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.79 Safari/537.36',
    'Sec-Fetch-User': '?1',
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
    'Sec-Fetch-Site': 'none',
    'Sec-Fetch-Mode': 'navigate',
    'Accept-Encoding': 'gzip, deflate, br',
    'Accept-Language': 'en-US,en;q=0.9,hi;q=0.8',
}

response = requests.get('https://www.nseindia.com/live_market/dynaContent/live_watch/option_chain/optionKeys.jsp?segmentLink=17&instrument=OPTIDX&symbol=BANKNIFTY', headers=headers)

这现在可以在普通的Linux VPS和Windows计算机中完美运行，但是，在Google Collab中不起作用。

为什么？

它看起来很基础！ 它在Google Collab中给出了连接超时错误。

ConnectionResetError                      Traceback (most recent call last)

我想念什么？但是我们已经解决了房间里的大象。

Google不会阻止该URL，因为我正在与其他Google Services无缝地使用它。所以它让我发痒。

此外，它在几个VPS中也无法使用！
