python通过socket远程连接错误处理代码演示
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/1.0\r\n\r\n" % 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)
