Question

我是新手，我正在尝试安装一个简单的hello world应用程序，但它一直返回“NotFound：（404，”找不到路径'/'。“）”，但我已经定义了它。

这是我得到的，

在 __ init __ .py

import cherrypy
from HomeNetMain import HomeNetMain

cherrypy.config.update("global.cfg")
#I have tried "" for the script name parm but that doesn't work
cherrypy.tree.mount(HomeNetMain,"/","main.cfg") 
cherrypy.engine.start()
cherrypy.quickstart()

我有另一个文件

import cherrypy

class HomeNetMain:

    @cherrypy.expose
    def index(self):
       return "Hello World"

我试过装饰器和index.exposed = True都没有用（子问题是装饰器或index.exposed的首选方法是什么）

global.cfg

[global]
server.socket_host: "127.0.0.1"
server.socket_port: 9080
log.screen: True
log.error_file: "/tmp/cherrypy.error"
log.access_file: "/tmp/cherrypy.access"

main.cfg

[/]
log.screen: True
log.error_file: "/tmp/homenet.error"
log.access_file: "/tmp/homenet.access"

我感谢任何帮助，提前谢谢。

这是完整的堆栈跟踪

Traceback (most recent call last):

NotFound: (404, "The path '/' was not found.")

Answer 1

原来我不应该使用cherrypy.quickstart（）我将代码更改为以下内容并且工作正常

cherrypy.engine.start()
cherrypy.engine.block()

Answer 2

正在安装类 HomeNetMain，而不是实例。由于 index 不是classmethod，因此将抛出TypeError，框架将其作为404处理。

cherrypy.tree.mount(HomeNetMain(), "/", "main.cfg")

Cherrypy返回NotFound：（404，“未找到路径'/'。”）
