在单个CherryPy应用程序中将REST调度程序与默认调度程序结合

本文介绍了在单个CherryPy应用程序中将REST调度程序与默认调度程序结合的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试让CherryPy通过 cherrypy.dispatch.MethodDispatcher()和所有其他请求(例如/)到一些默认的调度程序.

I'm trying to make CherryPy to handle request to /api via cherrypy.dispatch.MethodDispatcher() and all other request (like /) to some default dispatcher.

阅读CherryPy的文档后，我不知道如何执行此操作.他们仅分别使用两种路由方法，但这是一件非常基本的事情，我认为它必须协同工作.

After reading CherryPy's doc I have no idea how to do this. They use both routing methods only separately but this is such a basic thing that I believe it has to work together.

#!/usr/local/bin/python2.7 import cherrypy class Root(object): @cherrypy.expose def index(self): return 'Hello world' class RestAPI(object): @cherrypy.expose def POST(self, blah): return 'ok' cherrypy.config.update({ 'global': { 'environment': 'production', 'server.socket_host': '127.0.0.1', 'server.socket_port': 8080, } }) root = Root() root.api = RestAPI() conf = { '/api': { 'request.dispatch': cherrypy.dispatch.MethodDispatcher() } } cherrypy.quickstart(root, '', config=conf)

通过调用 curl'localhost:8080/'，它为我提供了 Hello world ，这是正确的.但是调用 curl -X POST'localhost:8080/api'只会返回404.

By calling curl 'localhost:8080/' it gives me Hello world which is correct. But calling curl -X POST 'localhost:8080/api' returns just 404.

顺便说一句，这个问题完全相同，没有任何答案 CherryPy MethodDispatcher与多个网址路径.

By the way, the're eaxctly the same question without any answer CherryPy MethodDispatcher with multiple url paths.

推荐答案

最后，我解决了它.奇怪的是，我不得不使用注释 @ cherrypy.expose 公开 index 方法(以及 Root 类中的所有其他方法)，而不仅仅是通过像 RestAPI 类中那样设置 exposed = True .我不知道为什么.

Finally I solved it. The weird thing was that I had to expose index method (and all other methods in Root class) using annotation @cherrypy.expose and not just by setting exposed = True like in RestAPI class. I don't know why.

要正确测试POST处理程序，我不必传递任何变量，但仍然必须设置 Content-length:0 标头.

To properly test POST handler I didn't have to pass any variables but still I had to set Content-length: 0 header.

class Root(object): @cherrypy.expose def index(self): return 'Hello world' class RestAPI(object): exposed = True def POST(self): return 'post' def GET(self): return 'get' cherrypy.config.update({ 'global': { 'environment': 'test_suite', 'server.socket_host': '127.0.0.1', 'server.socket_port': 8080, } }) cherrypy.tree.mount(Root()) cherrypy.tree.mount(RestAPI(), '/api', {'/': {'request.dispatch': cherrypy.dispatch.MethodDispatcher()} } ) cherrypy.engine.start() cherrypy.engine.block()

使用cURL测试POST的正确方法:

Proper way to test POST using cURL:

curl -X POST --header"Content-length:0" localhost:8080/api
