1:pycurl模塊的安裝方法

easy_install pycurl
pip install pycurl

2:示例代碼如下，是在python3下實現的，如若使用python2稍作修改即可

# -*- coding: utf-8 -*-
import os,sys
import time
import sys
import pycurl

URL="https://www.baidu.com"
c = pycurl.Curl()
c.setopt(pycurl.URL, URL)

#連接超時時間,5秒
c.setopt(pycurl.CONNECTTIMEOUT, 5)

#下載超時時間,5秒
 

c.setopt(pycurl.TIMEOUT, 5)
c.setopt(pycurl.FORBID_REUSE, 1)
c.setopt(pycurl.MAXREDIRS, 1)
c.setopt(pycurl.NOPROGRESS, 1)
c.setopt(pycurl.DNS_CACHE_TIMEOUT,30)
indexfile = open(os.path.dirname(os.path.realpath(__file__))+"/content.txt", "wb")
c.setopt(pycurl.WRITEHEADER, indexfile)
c.setopt(pycurl.WRITEDATA, indexfile)
 
try:
    c.perform()
except Exception as e:

    indexfile.close()
