如何将cherrypy用作静态文件的Web服务器？

pip install cherrypy

import os
import cherrypy

class StaticFilesServer(object):
    @cherrypy.expose
    def index(self):
        raise cherrypy.HTTPRedirect('/static/index.html')

    @cherrypy.expose
    def static(self, *args):
        path = os.path.join(*args)
        if os.path.isfile(path):
            return cherrypy.lib.static.serve_file(path)
        else:
            raise cherrypy.HTTPError(404, 'File not found')

if __name__ == '__main__':
    cherrypy.config.update({
        'server.socket_host': '0.0.0.0',
        'server.socket_port': 8080,
        'server.thread_pool': 10
    })
    cherrypy.tree.mount(StaticFilesServer(), '/', {
        '/static': {
            'tools.staticdir.on': True,
            'tools.staticdir.dir': './static',
            'tools.staticdir.index': 'index.html'
        }
    })
    cherrypy.engine.start()
    cherrypy.engine.block()

python app.py
