Python的请求库超时，但从浏览器获取响应

Question

我正在尝试为nba数据创建一个web刮板。当我运行下面的代码：

import requests 

response = requests.get('https://stats.nba.com/stats/leaguedashplayerstats?College=&Conference=&Country=&DateFrom=10%2F20%2F2017&DateTo=10%2F20%2F2017&Division=&DraftPick=&DraftYear=&GameScope=&GameSegment=&Height=&LastNGames=0&LeagueID=00&Location=&MeasureType=Base&Month=0&OpponentTeamID=0&Outcome=&PORound=0&PaceAdjust=N&PerMode=Totals&Period=0&PlayerExperience=&PlayerPosition=&PlusMinus=N&Rank=N&Season=2017-18&SeasonSegment=&SeasonType=Regular+Season&ShotClockRange=&StarterBench=&TeamID=0&VsConference=&VsDivision=&Weight=') 

请求与错误超时：

File "C:\ProgramData\Anaconda3\lib\site-packages\requests\api.py", line 70, in get return request('get', url, params=params, **kwargs)

File "C:\ProgramData\Anaconda3\lib\site-packages\requests\api.py", line 56, in request return session.request(method=method, url=url, **kwargs)

File "C:\ProgramData\Anaconda3\lib\site-packages\requests\sessions.py", line 488, in request resp = self.send(prep, **send_kwargs)

File "C:\ProgramData\Anaconda3\lib\site-packages\requests\sessions.py", line 609, in send r = adapter.send(request, **kwargs)

File "C:\ProgramData\Anaconda3\lib\site-packages\requests\adapters.py", line 473, in send raise ConnectionError(err, request=request)

ConnectionError: ('Connection aborted.', OSError("(10060, 'WSAETIMEDOUT')",))

然而，当我打相同的URL在浏览器中，我得到了响应。

看起来您提到的网站正在请求的标题中检查"User-Agent"。您可以在请求中伪造"User-Agent"，使其看起来像来自实际的浏览器，您将收到回复。

例如：

>>> import requests 
>>> url = "https://stats.nba.com/stats/leaguedashplayerstats?College=&Conference=&Country=&DateFrom=10%2F20%2F2017&DateTo=10%2F20%2F2017&Division=&DraftPick=&DraftYear=&GameScope=&GameSegment=&Height=&LastNGames=0&LeagueID=00&Location=&MeasureType=Base&Month=0&OpponentTeamID=0&Outcome=&PORound=0&PaceAdjust=N&PerMode=Totals&Period=0&PlayerExperience=&PlayerPosition=&PlusMinus=N&Rank=N&Season=2017-18&SeasonSegment=&SeasonType=Regular+Season&ShotClockRange=&StarterBench=&TeamID=0&VsConference=&VsDivision=&Weight=" 
>>> 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'} 

>>> response = requests.get(url, headers=headers) 
>>> response.status_code 
200 

>>> response.text # will return the website content
