httplib.InvalidURL:非数字端口: [英] httplib.InvalidURL: nonnumeric port:

问题描述

我正在尝试执行一个脚本来检查是否存在许多网址:

i'm trying to do a script which check if many urls exists:

import httplib

with open('urls.txt') as urls:
    for url in urls:
        connection = httplib.HTTPConnection(url)
        connection.request("GET")
        response = connection.getresponse()
        if response.status == 200:
            print '[{}]: '.format(url), "Up!"

但是我得到了这个错误:

But I got this error:

Traceback (most recent call last):
  File "test.py", line 5, in <module>
    connection = httplib.HTTPConnection(url)
  File "/usr/lib/python2.7/httplib.py", line 693, in __init__
    self._set_hostport(host, port)
  File "/usr/lib/python2.7/httplib.py", line 721, in _set_hostport
    raise InvalidURL("nonnumeric port: '%s'" % host[i+1:])
httplib.InvalidURL: nonnumeric port: '//globo.com/galeria/amazonas/a.html

怎么了?

推荐答案

httplib.HttpConnection在其构造函数中采用远程URL的host和port，而不是整个URL.

httplib.HttpConnection takes the host and port of the remote URL in its constructor, and not the whole URL.

对于您的用例，使用urllib2.urlopen更容易.

For your use case, it's easier to use urllib2.urlopen.

import urllib2

with open('urls.txt') as urls:
    for url in urls:
        try:
            r = urllib2.urlopen(url)
        except urllib2.URLError as e:
            r = e
        if r.code in (200, 401):
            print '[{}]: '.format(url), "Up!"
        elif r.code == 404:
            print '[{}]: '.format(url), "Not Found!"
