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。
