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。
