Python socket 上传文件的服务端和客户端

python服务端：

#coding=gbk  ''''' 等待连接 等待发送文件 读取数据 写入文件并且保存 等待连接 '''  import socket  import threading  import time  import struct  def function(newsock, address):      FILEINFO_SIZE = struct.calcsize('128sI')      '''''定义文件信息（包含文件名和文件大小）大小。128s代表128个char[]（文件名），I代表一个integer or long（文件大小）'''      while 1:               try:              fhead = newsock.recv(FILEINFO_SIZE)              filename, filesize = struct.unpack('128sI', fhead)              '''''把接收到的数据库进行解包，按照打包规则128sI'''              print "address is: ",address              print filename, len(filename),type(filename)              print filesize              filename = 'new_'+filename.strip('\00')#命名新文件new_传送的文件              fp = open(filename,'wb')#新建文件，并且准备写入              restsize = filesize              print "recving..."              while 1:                  if restsize > 1024:#如果剩余数据包大于1024，就去1024的数据包                      filedata = newsock.recv(1024)                  else:                      filedata = newsock.recv(restsize)                      fp.write(filedata)                      break                  if not filedata:                      break                  fp.write(filedata)                  restsize = testsize - len(filedata)#计算剩余数据包大小                  if restsize <= 0:                      break              fp.close()              print "recv succeeded !!File named:",filename          except:              print "he socket partner maybe closed"              newsock.close()              break  sock=socket.socket(socket.AF_INET, socket.SOCK_STREAM)#创建tcp连接  sock.bind(('127.0.0.1',8887))#定于端口和ip  sock.listen(5)#监听  while True:      newsock, address = sock.accept()      print "accept another connection"      tmpThread = threading.Thread(target=function,args=(newsock,address)) #如果接收到文件，创建线程      tmpThread.start()#执行线程  print 'end'  

 
python客户端:

php客户端:
