python实现带错误处理功能的远程文件读取方法

本文实例讲述了python/' target='_blank'>python实现带错误处理功能的远程文件读取方法。分享给大家供大家参考。具体如下：

import socket, sys, timehost = sys.argv[1]textport = "80"filename = sys.argv[3]try:  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  port = int(textport)  s.connect((host, port))  fd = s.makefile('rw', 0)  print "sleeping..."  time.sleep(10)  print "Continuing."  fd.write("GET %s HTTP/1.0\r\n\r\n" % filename)  fd.flush()      s.shutdown(1)  except socket.gaierror, e:  print "Address-related error connecting to server: %s" % e  sys.exit(1)except socket.error, e:  print "Connection error: %s" % e  sys.exit(1)while 1:  try:    buf = fd.read(2048)  except socket.error, e:    print "Error receiving data: %s" % e    sys.exit(1)  if not len(buf):    break  sys.stdout.write(buf)

希望本文所述对大家的Python程序设计有所帮助。
