finally:

from optparse import OptionParser

parser = OptionParser()

parser.add_option("-a", "--address", dest="address", default="localhost", help="ADDRESS for webserver", metavar="ADDRESS")

parser.add_option("-p", "--port", dest="port", type="int", default=80, help="PORT for webserver", metavar="PORT")

parser.add_option("-r", "--resource", dest="resource", default="index.html", help="RESOURCE to check", metavar="RESOURCE")

(options, args) = parser.parse_args()

print 'options: %s, args: %s' %(options, args)

check = check_webserver(options.address, options.port, options.resource)

print 'check_webserver returned %s' % check

sys.exit(not check)

運行結果：

成功
