    if __name__ == '__main__':
        from argparse import ArgumentParser

        parser.add_argument(

     使用httplib

    def check_webserver_by_httplib(address, port, resource):
        address = socket.gethostbyname(address)
        failed = False
        if not resource.startswith('/'):
            resource = '/' + resource
        try:
            conn = httplib.HTTPConnection(address, port)
            print 'HTTP connection created successfully'
            # make request
            conn.request('GET', resource)
            print 'request for %s successful' % (resource)
            # get response
            resp = conn.getresponse()
            print 'response status: %s' % resp.status
        except socket.error as e:
            print 'HTTP connection failed: %s' % e
            return False
        finally:
            conn.close()
            print 'HTTP connection closed successfully'
    
        if resp.status in [200, 301]:
            return True
        else:
            return False
