扫描代码如下：

# 1. 用户输 URL和 线程数
# 2. 将目录爆破字典添加到队列中
# 3. 创建线程
# 4. 定义目录爆破函数
import time
import queue
import threading
import urllib3
import sys

def main(URL, THREAD_NUMBER):
    # 2. 获取已添加好字典的队列
    Que = Que_add(URL)

    # 3. 创建线程，并使用多线程处理目录爆破
    threads = []
    for i in range(THREAD_NUMBER):
        t = threading.Thread(target=get_url,args=(Que, ))  #创建一个多线程的对象
        threads.append(t) #将多线程的对象传到数组
        t.start()
    for t in threads:
        t.join() #使用 t.join进行阻塞


# 2. 将目录爆破字典添加到队列中
def Que_add(URL):
    Que = queue.Queue()
    with open("dir.txt","r") as f:
        for i in f:

            Que.put(path)
    return Que


# 4. 定义目录爆破函数
