本文實(shí)例為大家分享了python實(shí)現(xiàn)UDP文件傳輸?shù)木唧w代碼，供大家參考，具體內(nèi)容如下

UDP協(xié)議下文件傳輸：

服務(wù)端

import socketcount = 0s = 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+=1print(’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)

客戶端

import socketimport osimport timedef Get_FilePath_FileName_FileExt(filename): filepath, tempfilename = os.path.split(filename) shotname, extension = os.path.splitext(tempfilename) return filepath, shotname, extensions = 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 = 0flag = 1while 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+=1print(’recircled’+str(count))s.closeend = 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()

此次試驗(yàn)為100000Byte大小的文件，運(yùn)行后查看服務(wù)器端信息：

客戶端上查看傳輸時(shí)延：

以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
