Python web套接字仅发送1个消息

Question

我一直在从事一个个人项目，并将数据从客户端发送到套接字主机。由于某些原因，套接字在第一条消息发出后关闭。我试着四处寻找如何解决这个问题，但实际上什么也找不到。顺便说一句，我真的是一个新的插座，并仍在努力学习如何使用它们。你知道吗

主机代码

import socket 
import sys 
from _thread import *

host = '' 
port = 5005 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)   
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

try:
    s.bind((host, port)) except socket.error as e:
    print(str(e))

s.listen(5) print('Waiting for a connection.')

def threaded_client(conn):
    reply = ''
    while True:
        data = conn.recv(2048)
        reply = reply + data.decode('utf-8')
        print(reply)
        if not data:
            print('someone left')
            break

    conn.close()

while True:

    conn, addr = s.accept()
    print('connected to: '+addr[0]+':'+str(addr[1]))

    start_new_thread(threaded_client,(conn,))

客户机代码

import socket

TCP_IP = '192.168.0.10'
TCP_PORT = 5005
BUFFER_SIZE = 1024

client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client.connect((TCP_IP, TCP_PORT))


l="Connection is Up and Running"

client.send(l.encode())
data = client.recv(BUFFER_SIZE).decode()

client.send(l.encode())
# print(client.send(l.encode()))
data = client.recv(BUFFER_SIZE).decode()
# print("received data:", data)
client.send(l.encode())
# print(client.send(l.encode()))
data = client.recv(BUFFER_SIZE).decode()
client.close()

主机端输出

Waiting for a connection.
connected to: 192.168.0.10:52228
Connection is Up and Running

在第一次调用client.send(l.encode())之后，客户机代码调用data = client.recv(BUFFER_SIZE).decode()，这意味着它尝试读取数据。另一端不发送任何数据（在服务器端代码中），因此客户端代码被阻塞。 –卡奇克
