import requests import time from multiprocessing.pool import Pool

def get_site_code(url): headers = {} r = requests.get(url, headers=headers,verify=False)

url_list = ['url','url'] pool = Pool(5) pool.map(get_site_code, url_list)

import requests import time from multiprocessing.pool import Pool def get_site_code(url): print(“正在访问:”,url) headers = {} r = requests.get(url, headers=headers,verify=False) print(“访问状态:”, r.status_code) time.sleep(1) url_list = [ “http://test.tooa.woa.com", “http://test.tooa.woa.com", “http://test.tooa.woa.com", “http://test.tooa.woa.com", ] pool = Pool(5) pool.map(get_site_code, url_list) pool.close() print(get_site_code(“http://test.tooa.woa.com"))
运行怎么报错呢

    This probably means that you are not using fork to start your

    This probably means that you are not using fork to start your

    in the main module:

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

import requests import time from multiprocessing.pool import Pool

def get_site_code(url): headers = {} r = requests.get(url, headers=headers,verify=False) if name == 'main':

url_list = ['url','url'] pool = Pool(5) pool.map(get_site_code, url_list)
