windows下用python写的bottle框架，HTML文件引用plotly.js，然后做不出图。plot.js是https://cdn.plot.ly/plotly-latest.min.js下下来的本地文件

import json

import bottle



@bottle.route("/getcount")
def getcount():
    return json.dumps([[1,2,3], [4,5,6]])

@bottle.route("/")
def handleRequestHTML():
    return bottle.static_file("Untitled-1.html", root="")


@bottle.route("/permitsnowtest.js")
def handleRequestCode():
    return bottle.static_file("permitsnowtest.js", root="")
@bottle.route("/plot.js")
def handleRequestCode():
    return bottle.static_file("plot.js", root="")


bottle.run(host='127.0.0.1', port='8086', debug=True)
