本文实例讲述了Python 实现的微信爬虫。分享给大家供大家参考，具体如下：

单线程版：

import urllib.request
import urllib.parse
import urllib.error
import re,time
headers = ("User-Agent",
      "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3107.4 Safari/537.36")
operner = urllib.request.build_opener()
operner.addheaders = [headers]
urllib.request.install_opener(operner)
list_url = []
###使用代理获取网页url内容
def use_proxy(url):
  try:
    # proxy = urllib.request.ProxyHandler({'http':proxy_addr})　　　　##使用代理版
    # operner = urllib.request.build_opener()
    # urllib.request.install_opener(operner)
    headers = ("User-Agent",
          "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3107.4 Safari/537.36")
    operner = urllib.request.build_opener()
    operner.addheaders = [headers]
    urllib.request.install_opener(operner)
    data = urllib.request.urlopen(url).read().decode('utf-8')
    # print (data)
    return data
  except urllib.error.URLError as e:
    if hasattr(e, "code"):
      print(e.code)
    elif hasattr(e, "reason"):
      print(e.reason)
  except Exception as e:
    print("exception" + str(e))
    time.sleep(1)
##获取要爬取的url
def get_url(key, pagestart, pageend):
  try:
    keycode = urllib.parse.quote(key)
    for page in range(pagestart, pageend + 1):
      url = "http://weixin.sogou.com/weixin?query=%s&_sug_type_=&s_from=input&_sug_=n&type=%d&page=1&ie=utf8" % (
      keycode, page)
      data1 = use_proxy(url)
      #print("data1的内容是", data1)
      listurl_pattern = '<h3>.*?("http://.*?)</h3>'
      result = re.compile(l
