线程通信-通过queque的方式进行线程通信

from queue import Queue

import time
import threading

def get_detail_html(queue):
    while True:
        url =queue.get()
    print(" get detail html started")
    time.sleep(2)
    print("get detail html end")



def get_detail_url(queue):
    while True:
        print(" get detail url started")
        time.sleep(2)
        for i in range(20):
            queue.put("https://123.com")
        print("get detail url end")



if __name__ == '__main__':
    detail_queue = Queue(maxsize=1000) # 创建一个消息队列
    # 创建一个线程给队列中添加数据
    thread_detail_url = threading.Thread(target=get_detail_url,args=(detail_queue,))
    # 开启10个线程并
    for i in range(10):
        html_thread = threading.Thread(target=get_detail_html,args=(detail_queue,))
        html_thread.start()
    # 队列阻塞直到执行完
    detail_queue.join()
    # detail_queue.task_done()# 退出
