Question

基本上我从stackoverflow复制了这些方法并根据我的需要对其进行了修改：

from http.client import HTTPConnection, HTTPSConnection
import select
connections = {}


def request(method, url, body=None, headers={}, **kwargs):
    scheme, _, host, path = url.split('/', 3)
    h = connections.get((scheme, host))
    if h and select.select([h.sock], [], [], 0)[0]:
        h.close()
        h = None
    if not h:
        Connection = HTTPConnection if scheme == 'http:' else HTTPSConnection
        h = connections[(scheme, host)] = Connection(host, **kwargs)
    h.request(method, '/' + path, body, headers)
    return h.getresponse()


def urlopen(url, data=None, *args, **kwargs):
    resp = request('POST' if data else 'GET', url, data, *args, **kwargs)
    if resp.status == 400:
        fileAccessed = resp.read()
        if 'failed to open stream: Permission denied' in str(fileAccessed):
            return "permission denied"
        else:
            return fileAccessed
    else:
        return "not found"

现在我使用它们与此示例类似：

with open('addons.txt', 'r') as addonsFile:
    for line in addonsFile:
        addon = line.rstrip()
        fileUrl = 'http://www.google.com/%s/ncr' % addon
        response = urlopen(fileUrl)

该程序获得第一个插件并使第一个请求正常。在第二次迭代中，我收到此错误：

Traceback (most recent call last):
  File "/root/add.py", line 45, in <module>
    response = urlopen(fileUrl)
  File "/root/add.py", line 26, in urlopen
    resp = request('POST' if data else 'GET', url, data, *args, **kwargs)
  File "/root/add.py", line 15, in request
    if h and select.select([h.sock], [], [], 0)[0]:
TypeError: argument must be an int, or have a fileno() method.

亲爱的stackoverflow领主，请帮我纠正我的程序！

是啊......所以......我不知道...... 我删除了我收到错误的部分：

  if h and select.select([h.sock], [], [], 0)[0]:
        h.close()
        h = None
    if not h:

现在一切正常。

Python 3.2：TypeError：参数必须是int，或者有一个fileno（）方法
