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-8import requestsfrom datetime import datetimeclass 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

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
