如何用Python编写UDP协议进行文件传输？

本文共计446个文字，预计阅读时间需要2分钟。

本例为家庭分享的Python实现UDP文件传输的代码示例，供大家参考。

UDP协议下文件传输：

服务端：pythonimport socketsocket_count=0s=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)server_addr=('', 0)s.bind(server_addr)socket_count +=1

客户端：pythonimport sockets=socket.socket(socket.AF_INET, socket.SOCK_DGRAM)s.connect(('localhost', 12345))

本文实例为大家分享了python实现UDP文件传输的具体代码，供大家参考，具体内容如下

UDP协议下文件传输：

服务端

import socket count = 0 s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) server_addr = ('127.0.0.1',9999) s.bind(server_addr) print('Bind UDP on 9999...') while True: if count == 0: data,client_addr = s.recvfrom(1024) print('connected from %s:%s'%client_addr) f = open(data, 'wb') data, client_addr = s.recvfrom(1024) if str(data) != "b'end'": f.write(data) print('recieved '+str(count)+' byte') else: break s.sendto('ok'.encode('utf-8'),client_addr) count+=1 print('recercled'+str(count)) f.close() s.close() # data, addr = s.recvfrom(1024) # print('Received from %s:%s' %addr) # s.sendto(b'Hello, %s!' %data, addr)

客户端

import socket import os import time def Get_FilePath_FileName_FileExt(filename): filepath, tempfilename = os.path.split(filename) shotname, extension = os.path.splitext(tempfilename) return filepath, shotname, extension s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) filename = input('please enter the filename you want to send:\n') filepath, shotname, extension = Get_FilePath_FileName_FileExt(filename) client_addr = ('127.0.0.1',9999) f = open(filename,'rb') count = 0 flag = 1 while True: if count == 0: data = bytes(shotname+extension, encoding = "utf8") start = time.time() s.sendto(data,client_addr) data = f.read(1024) if str(data) != "b''": s.sendto(data,client_addr) print(str(count)+'byte') else: s.sendto('end'.encode('utf-8'),client_addr) break data, server_addr = s.recvfrom(1024) count+=1 print('recircled'+str(count)) s.close end = time.time() print('cost'+str(round(end-start,2))+'s') # for data in [b'Michael',b'Tracy',b'Sarah']: # s.sendto(data,('127.0.0.1',9999)) # print(s.recv(1024).decode('utf-8')) # s.close()

此次试验为100000Byte大小的文件，运行后查看服务器端信息：

客户端上查看传输时延：
