需求分析

项目上需要用到手机号前7位，判断号码是否合法，还有归属地查询。旧的数据是几年前了太久了，打算用python爬虫重新爬一份

单线程版本

# coding:utf-8

from datetime import datetime


class PhoneInfoSpider:
  def __init__(self, phoneSections):
    self.phoneSections = phoneSections

  def phoneInfoHandler(self, textData):
    text = textData.splitlines(True)
    # print("text length:" + str(len(text)))

    if len(text) >= 9:
      number = text[1].split('\'')[1]
      province = text[2].split('\'')[1]
      mobile_area = text[3].split('\'')[1]
      postcode = text[5].split('\'')[1]
      line = "number:" + number + ",province:" + province + ",mobile_area:" + mobile_area + ",postcode:" + postcode
      line_text = number + "," + province + "," + mobile_area + "," + postcode
      print(line_text)
      # print("province:" + province)

      try:
        f = open('./result.txt', 'a')
        f.write(str(line_text) + '\n')
      except Exception as e:
        print(Exception, ":", e)

  def requestPhoneInfo(self, phoneNum):
    try:
      url = 'https://tcc.taobao.com/cc/json/mobile_tel_segment.htm?tel=' + phoneNum
      response = requests.get(url)
      self.phoneInfoHandler(response.text)
    except Exception as e:
      print(Exception, ":", e)

  def requestAllSections(self):
    # last用于接上次异常退出前的号码
    last = 0
    # last = 4
    # 自动生成手机号码，后四位补0
    for head in self.phoneSections:
      head_begin = datetime.now()
      print(head + " begin time:" + str(head_begin))

      # for i in range(last, 10000):
      for i in range(last, 10):
        middle = str(i).zfill(4)
        phoneNum = head + middle + "0000"
        self.requestPhoneInfo(phoneNum)
      last = 0

      head_end = datetime.now()
      print(head + " end time:" + str(head_end))


if __name__ == '__main__':
  task_begin = datetime.now()
  print("phone check begin time:" + str(task_begin))

  # 电信，联通，移动，虚拟运营商
  dx = ['133', '149', '153', '173', '177', '180', '181', '189', '199']
  lt = ['130', '131', '132', '145', '146', '155', '156', '166', '171', '175', '176', '185', '186', '166']
  yd = ['134', '135', '136', '137', '138', '139', '147', '148', '150', '151', '152', '157', '158', '159', '172',
     '178', '182', '183', '184', '187', '188', '198']
  add = ['170']
  all_num = dx + lt + yd + add

  # print(all_num)
  print(len(all_num))

  # 要爬的号码段
  spider = PhoneInfoSpider(all_num)
  spider.requestAllSections()

  task_end = datetime.now()
  print("phone check end time:" + str(task_end))

发现爬取一个号段，共10000次查询，单线程版大概要多1个半小时，太慢了。

多线程版本

    threading.Thread.__init__(self)

  global lock
  while True:
    lock.acquire()
    if q.qsize() != 0:
      print("queue size:" + str(q.qsize()))
      p = q.get() # 获得任务
      lock.release()

      middle = str(9999 - q.qsize()).zfill(4)
      phoneNum = phone_head + middle + "0000"
      print("phoneNum:" + phoneNum)

      try:

     '182', '183', '184', '187', '188', '198']
  all_num = dx + lt + yd
  print(len(all_num))

  for head in all_num:
    head_begin = datetime.now()
    print(head + " begin time:" + str(head_begin))

    q = queue.Queue()
    threads = []
    lock = threading.Lock()

    for p in range(10000):
      q.put(p + 1)

    print(q.qsize())

    for i in range(threadNum):
      middle = str(i).zfill(4)
      global phone_head
      phone_head = head

      thread = MyThread(requestPhoneInfo)
      thread.start()
      threads.append(thread)
    for thread in threads:
      thread.join()

    head_end = datetime.now()
    print(head + " end time:" + str(head_end))

  task_end = datetime.now()
  print("phone check end time:" + str(task_end))

多线程版的1个号码段1000条数据，大概2，3min就好，cpu使用飙升，大概维持在70%左右。

总共40多个号段，爬完大概1，2个小时，总数据41w左右

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持python博客。
