我通常在这里不问问题,但这对Google而言并不容易.

基本上,我正在尝试从客户端向服务器发送一些数据.这是一个非常简单的客户端/服务器设置.

我只向您显示代码和输出.任何帮助表示赞赏！

server.py代码

#!/usr/bin/env python

import socket

host = ''
port = 50000
backlog = 5
size = 1024
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host,port))
s.listen(backlog)

while 1: #always listening
    client, address = s.accept() #gets client
    data = client.recv(size) #gets message
    if data:
        print("Client: ", data)
    client.close() #close, and listen for new client

server.py输出

Python 3.3.1 (v3.3.1:d9893d13c628, Apr  6 2013, 20:30:21) [MSC v.1600 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> ================================ RESTART ================================
>>> 
Client:  b'Hello World!'

client.py代码

import socket

msg = 'Hello World!'
msg = str.encode(msg, 'utf-8')
clientsocket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
clientsocket.connect(('brandon-pc4', 50000))
clientsocket.send(msg)
print(msg)

client.py输出

Python 3.3.4 (v3.3.4:7ff62415e426, Feb 10 2014, 18:12:08) [MSC v.1600 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> ================================ RESTART ================================
>>> 
b'Hello World!'
>>> 

解决方法:

好,您需要进行以下更改：

在server.py中：

print("Client: ", data.decode())

在client.py中：

print(msg.decode())

因为如documentation中所述,unicode.encode()方法输出一个字节字符串,需要使用.decode()将其转换回字符串.
