5.1 方法一，代码：
import cherrypy
class HelloWorld(object):
@cherrypy.expose
def index(self):
return "Hello World!"
cherrypy.quickstart(HelloWorld())运行示范：
5.2 方法二，代码：
import cherrypy
class HelloWorld:
def index(self):
return "Hello world!"
index.exposed = True #暴露设置为true，区别
cherrypy.quickstart(HelloWorld()) 5.3 方法三，代码：
import cherrypy
class HelloWorld(object):
@cherrypy.expose
def index(self):
return "Hello world!"
if __name__ == '__main__':
cherrypy.quickstart(HelloWorld())6 显示html的plotly的柱状图法
