1、遞歸遍歷目錄下所有文件并通過finder函數定位指定格式字符串

2、用來查找字符串的finder函數是自己定義的，這里定義了一個ip_port_finder通過正則表達式查找ip:port格式（粗匹配：數字.數字.數字.數字:數字）的字符串

3、用gevent來實現協程并發完成耗時任務

代碼如下：

									# -*- coding: utf-8 -*-

									import re

									from os.path import join

									from os import walk

									from gevent import monkey

									import gevent

									monkey.patch_all()

									def ip_port_finder(str: str) -> bool:

									  pattern = re.compile(r".+\d+\.\d+\.\d+\.\d+:\d+")

									  matchObj = pattern.match(str)

									  if matchObj:

									    print("------")

									    print(f"發現目標：{matchObj.group(0)}")

									    return True

									  else:

									    return False

									def find_in_file(file_path, finder):

									  with open(file_path, "r", encoding="utf-8", errors='ignore') as f:

									    for (num, value) in enumerate(f):

									      if finder(value):

									        print(f"文件路徑：{file_path}")

									        print(f"所在行數：{num}")

									find_in_path_recursively = lambda path, finder: gevent.joinall(

									  [gevent.spawn(find_in_file, join(root, file_name), finder) for root, directories, f_names in walk(path) for

									   file_name in f_names])

									if __name__ == '__main__':

									  path = "E:\dev_codes\xxx"

									  find_in_path_recursively(path, ip_port_finder)
