httplib.InvalidURL:非数字端口：

Question

我正在尝试执行一个脚本，该脚本检查是否存在多个URL：

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!"

但我犯了个错误：

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？

httplib.HttpConnection在其构造函数中获取远程URL的host和port，而不是整个URL。

对于您的用例，更容易使用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!"
