问题描述
所以我正在用 python 编写一个基于 TCP 的代码,它从客户端发送 2 个变量(用户名和密码),服务器接收这 2 个变量,并基于这些变量,它做了一些事情,但我的问题是我的客户端没有t 接收第二个变量!
客户端代码:
# Variables
ip = "127.0.0.1"
port = 6767
username = "User"
password = "1234
# Connect To Server
client = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client.connect((ip,port))
# Send Information to Server
information_message = client.recv(1024).decode('ascii')
while True:
if information_message == 'PASSWORD':
client.send(password.encode('ascii'))
print(information_message)
if information_message == 'USERNAME':
client.send(username.encode('ascii'))
print(information_message)
break
服务器代码:
import socket
# Connection Data
host = '127.0.0.1'
port = 6767
# Starting Server
server = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
server.bind((host,port))
server.listen()
# receive information to client
while True:
client,address = server.accept()
client.send('PASSWORD'.encode('ascii'))
password = client.recv(10240).decode('ascii')
client.send('USERNAME'.encode())
username = client.recv(10240).decode('ascii')
print(username,password)
break
期待 server.py:
user 1234
server.py 上的真实输出:
Traceback (most recent call last):
File "C:\Users\Administrator\PycharmProjects\test\server.py",line 29,in <module>
username = client.recv(10240).decode('ascii')
ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host
我知道只有 ('PASSWORD') 会作为数据发送给客户端,但我不明白为什么它不会发送第二个数据 ('USERNAME')
