本文实例讲述了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, time
host = 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。
