Question

我在尝试在cherryPy服务器中配置全局404错误时遇到问题。

这是我的代码。

import cherrypy
import os,os.path

import view.costume_functions as cf
import model.database as db
import temp.template as tm

class Maple_syrup_project(object):

    @cherrypy.expose
    def index(self):

        query = db.get_racks()
        estado = {}

        for rack in query:
            ip_address = rack[1]
            key = rack[0]
            estado[key] = cf.estado_actal(ip_address)

        return tm.rack_all(query,estado)

    @cherrypy.expose
    def configurar(self,**post):
        comando = cf.comando(post)
        rack_id = post['rack_id']
        ip_address = db.get_ip(rack_id);
        respuesta = cf.connection(ip_address,comando)
        return comando
        return 'configurando...'+comando+'....'+respuesta

def error_page_404(status, message, traceback, version):
        return ('Oppps Error')

cherrypy.root = Maple_syrup_project()

if __name__=='__main__':
    configurations = {
        '/':{
            'tools.staticdir.root':os.path.abspath(os.getcwd())
        },
        '/static':{
            'tools.staticdir.on':True,
            'tools.staticdir.dir':'./static'
        }
    }

    cherrypy.config.update({'server.socket_port':9999,
                            'server.socket_host':'0.0.0.0',
                            'error_page.404': error_page_404,
                            })

    cherrypy.tree.mount(Maple_syrup_project(),
                        '/control_de_retornos',
                         configurations)

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

如果我将浏览器指向ht ..：// ....：9999 / control_de_retornos / xxxxx 我得到了预期的服装错误'Ooops Error'。如果我将我的浏览器指向ht ..：// ....：9999 /或ht ..：// ....：9999 / xxxxx 我有一个空白页面，其中包含状态代码：标题中没有找到404，但这不是我的服装错误。

关于发生了什么的任何想法？谢谢。

尝试这样的事情......

import cherrypy
import os,os.path

class Maple_syrup_project(object):

    class control_de_retornos(object):
        @cherrypy.expose
        def index(self):

            return 'hi'

        @cherrypy.expose
        def configurar(self,**post):
            return 'configurando...'

def error_page_404(status, message, traceback, version):
        return ('Oppps Custom Error')

cherrypy.root = Maple_syrup_project()

if __name__=='__main__':
    configurations = {
        '/':{
            'tools.staticdir.root':os.path.abspath(os.getcwd()),
            'server.socket_port':9999,
            'server.socket_host':'0.0.0.0',
            'error_page.404': error_page_404,
        },
        '/static':{
            'tools.staticdir.on':True,
            'tools.staticdir.dir':'./static'
        }
    }

    cherrypy.tree.mount(Maple_syrup_project(),
                        '/',
                         configurations)

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

error_page_404需要与Maple_syrup_project分开，而不是“class control_de_retornos（object）：”的一部分。现在，当我走到你的路径的根，我得到“Oppps自定义错误”。希望这有帮助！

我解决了它添加另一个安装在'/'上的类并处理错误

import cherrypy
import os,os.path

import view.costume_functions as cf
import model.database as db
import temp.template as tm

class Maple_syrup_project(object):

    @cherrypy.expose
    def index(self):
        racks = db.get_racks()
        rack_collection = {}
        bson = {}

        for rack in racks:
            ip_address = rack[1]
            try:
                estado = cf.estado_actal(ip_address)
            except:
                return ('Opsss..... Error....... Verificar que los racks esten encendidos y bien conectados ala red')

            nombre = db.get_optos_name(ip_address)
            opto_collection = cf.create_bson(estado,nombre,rack)
            rack_collection['rack_'+str(rack[0])] = opto_collection

        bson['racks'] = rack_collection

        return tm.rack_all(bson)

    @cherrypy.expose
    def configurar(self,**post):
        comando = cf.comando(post)
        rack_id = post['rack_id']
        ip_address = db.get_ip(rack_id);
        respuesta = cf.connection(ip_address,comando)

        return 'configurando...'+comando+'....'+respuesta

class Index(object):
    pass

def error_page_404(status, message, traceback, version):
    return ('Oppps Error')


if __name__=='__main__':
    configurations = {
        '/':{
            'tools.staticdir.root':os.path.abspath(os.getcwd())
        },
        '/static':{
            'tools.staticdir.on':True,
            'tools.staticdir.dir':'./static'
        }
    }

    cherrypy.config.update({'server.socket_port':9998,
                            'server.socket_host':'0.0.0.0',
                            'error_page.404': error_page_404
                            })

cherrypy.tree.mount(Maple_syrup_project(),'/control_de_retornos',configurations)
cherrypy.tree.mount(Index(),'/',configurations)

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

cherryPy全局配置 - 服装404错误 -
