Python多進程不能將信息放入隊列

1.Python多進程不能將信息放入隊列
2.代碼：

from urllib import request
from bs4 import BeautifulSoup
from multiprocessing import Manager
from multiprocessing import Pool
import os

def hand_url(url,name,queue):
    room_message = {} #存放我需要的信息

    print(name,os.getpid())
    one_roomlist=[]
    req=request.Request(url)
    req.add_header('User-Agent','Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36')
    with request.urlopen(req)as f:
        data = f.read().decode()
    soup = BeautifulSoup(data, 'html.parser')
    clear_1 = soup.find_all(class_="table_type_7 responsive_table full_width t_align_l")
    clear_1 = clear_1[0].tbody.contents
    for i in clear_1:
        if i != '\n':
            message_small = []
            for x in i.strings:
                if x != '\n':
                    message_small.append(x)


            one_roomlist.append(message_small)

        room_message[name] = one_roomlist

                  #前半部分為爬去網頁信息和篩選內容
    print(room_message)
    queue.put(room_message)     #程序在這里卡住了，room_message為一個字典
    print('ok')



if __name__ == '__main__':
    queue=Manager().Queue()
    pool = Pool(4)
    pool.apply_async(hand_url,('http://202.115.129.139:81/trainingroomnote?roomid=91','A405',queue))
    pool.close()
    pool.join()
    print(queue.get())

3.問題截圖

4.我自己嘗試把print(room_message)得到的內容直接復制添加到隊列里面是可以的，但是一旦改成queue.put(room_message)程序是卡在這里的
