【问题描述】：

我正在尝试，但它给出了错误：

Traceback (most recent call last):
File "download_torrent.py", line 11, in <module>
  torr_file = urllib2.urlopen(url)
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\urllib2.py", line 154, in urlopen
  return opener.open(url, data, timeout)
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\urllib2.py", line 431, in open
  response = self._open(req, data)
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\urllib2.py", line 449, in _open
  '_open', req)
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\urllib2.py", line 409, in _call_chain
  result = func(*args)
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\urllib2.py", line 1240, in https_open
  context=self._context)
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\urllib2.py", line 1200, in do_open
  r = h.getresponse(buffering=True)
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\httplib.py", line 1132, in getresponse
  response.begin()
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\httplib.py", line 453, in begin
  version, status, reason = self._read_status()
File "C:\Users\Aly Akhtar\AppData\Local\Continuum\Anaconda\lib\httplib.py", line 417, in _read_status
  raise BadStatusLine(line)
httplib.BadStatusLine: '' 

以下是我正在尝试的代码：

url = 'https://torcache.net/torrent/7E74F1E4AEDC08A2D63BE1EDF612AC0BF17ECBBD.torrent?title=[kat.cr]batman.v.superman.dawn.of.justice.2016.720p.hdtc.1.2gb.shaanig'
torr_file = urllib2.urlopen(url)
with open("mytorrent.torrent", "w") as f:
    f.write(torr_file.read())

我已经解决了几个类似的问题，但找不到解决方案。

【参考方案1】：

您尝试下载的网站似乎会丢弃标头中没有User-Agent 字符串的请求。我在这里找到了解决您问题的方法：https://***.com/a/9265980/1577207。

添加User-Agent 标头为我解决了这个问题：

import urllib2
url = 'https://torcache.net/torrent/7E74F1E4AEDC08A2D63BE1EDF612AC0BF17ECBBD.torrent?title=[kat.cr]batman.v.superman.dawn.of.justice.2016.720p.hdtc.1.2gb.shaanig'

opener = urllib2.build_opener()

headers = 
   'User-Agent': 'Mozilla/5.0 (Windows NT 5.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1',


opener.addheaders = headers.items()
torr_file = opener.open(url)
with open("mytorrent.torrent", "w") as f:
    f.write(torr_file.read())

【讨论】：

它确实解决了我上面提到的问题，谢谢。但是现在使用客户端打开torrent文件时会报错：torrent is not valid bencoding

@AlyAkhtar 您可以尝试将'b' 选项添加到open()，如下所示：open(file, 'wb') 用于二进制文件写入。
