python:socket傳輸大檔案樣本,

檔案可以傳輸,但是對比傳輸前後的檔案:socket_test.txt,末尾有一些不一致服務端代碼:

#!/usr/bin/python# -*- coding: utf-8 -*-import sysreload(sys)sys.setdefaultencoding("utf-8")import time'''等待串連等待傳送檔案讀取資料寫入檔案並且儲存等待串連'''import socketimport threadingimport timeimport structdef function(newsock, address):  FILEINFO_SIZE = struct.calcsize('128sI')  '''定義檔案資訊(包含檔案名稱和檔案大小)大小。128s代表128個char[](檔案名稱),I代表一個integer or long(檔案大小)'''  while 1:    try:      fhead = newsock.recv(FILEINFO_SIZE)      filename, filesize = struct.unpack('128sI', fhead)      '''把接收到的資料庫進行解包,按照打包規則128sI'''      print "address is: ", address      print filename, len(filename), type(filename)      print filesize      #filename = 'new_'+filename.strip('\00') # 命名新檔案new_傳送的檔案      filename = filename.strip('\00')      fp = open(filename, 'wb') # 建立檔案,並且準備寫入      restsize = filesize      print "recving..."      while 1:        if restsize > 102400: # 如果剩餘資料包大於1024,就去1024的資料包          filedata = newsock.recv(10240)        else:          filedata = newsock.recv(restsize)          fp.write(filedata)          #break        if not filedata:          break        fp.write(filedata)        restsize = restsize - len(filedata) # 計算剩餘資料包大小        if restsize <= 0:          break      fp.close()      print "recv succeeded !!File named:", filename    except Exception, e:      print unicode(e).encode('gbk')      print "the socket partner maybe closed"      newsock.close()      breaksock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 建立tcp串連sock.bind(('10.240.146.82', 8887)) # 定於連接埠和ipsock.listen(5) # 監聽while True:  newsock, address = sock.accept()  print "accept another connection"  tmpThread = threading.Thread(target=function, args=(newsock, address)) # 如果接收到檔案,建立線程  tmpThread.start() # 執行線程print 'end'

用戶端代碼:

#!/usr/bin/python# -*- coding: utf-8 -*-import sysreload(sys)sys.setdefaultencoding("utf-8")'''輸入檔案名稱,並且上傳'''import socketimport timeimport structimport osf = open('socket_test.txt', 'wb')for i in range(1000000):  f.write('for socket test, the line number is : ' + str(i) + '\n')f.close()sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)sock.settimeout(50)e = 0try:  sock.connect(('10.240.146.82', 8887))  print 'connect...'except socket.timeout, e:  print 'timeout', eexcept socket.error, e:  print 'error', eexcept e:  print 'any', eif not e:  #while (1):    #filename = raw_input('input your filename------->') # 輸入檔案名稱  filename = 'socket_test.txt'  FILEINFO_SIZE = struct.calcsize('128sI') # 編碼格式大小  fhead = struct.pack('128sI', filename, os.stat(filename).st_size) # 按照規則進行打包  sock.send(fhead) # 傳送檔案基本資料資料  fp = open(filename, 'rb')  fp2 = open('local_test.txt','wb')  i = 0  while 1: # 傳送檔案    filedata = fp.read(10240)    if not filedata:      break    sock.sendall(filedata)    fp2.write(filedata)    print i    i = i + 1  print "sending over..."  fp.close()  fp2.close()
