我正在尝试通过使用Python 3存储在.txt文件中的URL下载图像,并且在尝试在某些网站上执行此操作时出现错误。这是我得到的错误:

 File "C:/Scripts/ImageScraper/ImageScraper.py", line 14, in <module>
 dl()
 File "C:/Scripts/ImageScraper/ImageScraper.py", line 10, in dl
 urlretrieve(URL, IMAGE)
 File "C:\Python34\lib\urllib\request.py", line 186, in urlretrieve
 with contextlib.closing(urlopen(url, data)) as fp:
 File "C:\Python34\lib\urllib\request.py", line 161, in urlopen
 return opener.open(url, data, timeout)
 File "C:\Python34\lib\urllib\request.py", line 469, in open
 response = meth(req, response)
 File "C:\Python34\lib\urllib\request.py", line 579, in http_response
 'http', request, response, code, msg, hdrs)
 File "C:\Python34\lib\urllib\request.py", line 507, in error
 return self._call_chain(*args)
 File "C:\Python34\lib\urllib\request.py", line 441, in _call_chain
 result = func(*args)
 File "C:\Python34\lib\urllib\request.py", line 587, in http_error_default
 raise HTTPError(req.full_url, code, msg, hdrs, fp)
 urllib.error.HTTPError: HTTP Error 403: Forbidden

使用此代码:

from urllib.request import urlretrieve

def dl():
    with open('links.txt', 'r') as input_file:
        for line in input_file:
            URL = line
            IMAGE = URL.rsplit('/',1)[1]
            urlretrieve(URL, IMAGE)


if __name__ == '__main__':
    dl()

我假设它是因为他们不允许'机器人'访问他们的网站,但通过一些研究我发现有一种方法,至少在使用urlopen时,但我无法将解决方法应用于我的代码当我使用urlretrieve时。是否有可能让它发挥作用?

我认为该错误是一个实际的HTTP错误:403,称禁止访问该URL。您可能希望在访问URL之前尝试打印该URL,并尝试通过浏览器访问该URL。你还应该得到一个禁止的错误(403)。详细了解http_status_codes,特别是403 forbidden
