python实现实现UDP协议下的文件传输 协议下的文件传输 主要为大家详细介绍了python实现UDP协议下的文件传输，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣 的小伙伴们可以参考一下 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： 协议下文件传输： 服务端服务端 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：
