python使用socket远程连接错误处理方法

本文实例讲述了python使用socket远程连接错误处理方法。分享给大家供大家参考。具体如下：

import socket, sys
host = sys.argv[1]
textport = sys.argv[2]
filename = sys.argv[3]
try:
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except socket.error, e:
  print "Strange error creating socket: %s" % e
  sys.exit(1)
try:
  port = int(textport)
except ValueError:
  print "Couldn't find your port: %s" % e
  sys.exit(1)
try:
  s.connect((host, port))
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)
try:
  s.sendall("GET %s HTTP/1.0rnrn" % filename)
except socket.error, e:
  print "Error sending data: %s" % e
  sys.exit(1)
while 1:
  try:
    buf = s.recv(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。
