开发环境：

• Python2.7 + win10

开始先说一下，访问youtube需要那啥的，请自行解决，最好是全局代理。

实现代码：

from bs4 import BeautifulSoup
import lxml
import Queue
import requests
import re,os,sys,random
import threading
import logging
import json,hashlib,urllib
from requests.exceptions import ConnectTimeout,ConnectionError,ReadTimeout,SSLError,MissingSchema,ChunkedEncodingError
import random
