CherryPy和restfulwebapi

我不知道这是否是“最好”的方法,但我是这样做的:

import cherrypy

class RESTResource(object):
   """
   Base class for providing a RESTful interface to a resource.

   To use this class, simply derive a class from it and implement the methods
   you want to support.  The list of possible methods are:
   handle_GET
   handle_PUT
   handle_POST
   handle_DELETE
   """
   @cherrypy.expose
   def default(self, *vpath, **params):
      method = getattr(self, "handle_" + cherrypy.request.method, None)
      if not method:
         methods = [x.replace("handle_", "")
            for x in dir(self) if x.startswith("handle_")]
         cherrypy.response.headers["Allow"] = ",".join(methods)
         raise cherrypy.HTTPError(405, "Method not implemented.")
      return method(*vpath, **params);

class FooResource(RESTResource):
    def handle_GET(self, *vpath, **params):
        retval = "Path Elements:<br/>" + '<br/>'.join(vpath)
        query = ['%s=>%s' % (k,v) for k,v in params.items()]
        retval += "<br/>Query String Elements:<br/>" + \
            '<br/>'.join(query)
        return retval

class Root(object):
    foo = FooResource()

    @cherrypy.expose
    def index(self):
        return "REST example."

cherrypy.quickstart(Root())

RESTResource 类并使用前缀为的同名方法处理所需的RESTful动词(GET、PUT、POST、DELETE) handle_ . 如果不处理特定的动词(如POST),基类将引发一个 405 Method Not Implemented

vpaths 并传入任何查询字符串 params . 如果您需要 /foo/bar?woo=hoo , vpath[0] bar ,和 参数 {'woo': 'hoo'} .

更多信息可在CherryPy文档中找到: http://cherrypy.readthedocs.io/en/latest/tutorials.html#tutorial-7-give-us-a-rest

下面还详细介绍了如何使用CherryPy工具发送和接收JSON: http://tools.cherrypy.org/wiki/JSON

所以你想转换/getOrders?使用Cherrypy将account=X&type=Y转换为/orders/account/type。

我会尝试 http://cherrypy.readthedocs.org/en/latest/tutorial/REST.html 正如@Tomasz Blachowicz提到的,经过一些修改。

请记住,您可以使用

@cherrypy.expose
def order(account=None, type=None):
    print account, type

class Root(object):
    pass

root = Root()
root.orders = orders


cherrypy.quickstart(root, '/')

所以,如果你以中给出的例子为例 http://cherrypy.readthedocs.org/en/latest/tutorial/REST.html

class Orders(object):
    exposed = True
    def __init__(self):
        pass

    def GET(self, account=None, type=None):
        #return the order list for this account type
        return getOrders(account, type)

    def PUT(self, account=None, type=None, orders=None):
        #Set the orders associated with account or something
        setOrders(account, type, orders)


class Root(object):
    pass

root = Root()
root.orders = Orders()

conf = {
    'global': {
        'server.socket_host': '0.0.0.0',
        'server.socket_port': 8000,
    },
    '/': {
        'request.dispatch': cherrypy.dispatch.MethodDispatcher(),
    },
}

cherrypy.quickstart(root, '/', conf)

我喜欢这种方法,因为它很容易看到发生了什么,我相信,它回答了你的问题。

我想你已经尝试过教程中提到的部分匹配。我发现,虽然不是很好,但大多数时候它确实能完成任务。

除此之外,虽然我没试过,但Cherrypy显然支持 Routes (参见 http://www.cherrypy.org/wiki/PageHandlers ),这为您提供了各种RESTful选项。

要回答第二个问题,您需要定义并公开一个默认方法:

class getOrders(Object):
    def default(account, type):
        ...

    default.exposed = True

使用此方法,getOrders/x/y将映射到 default(account='x', type='y')

至于RESTful应用程序,我非常肯定默认页面处理程序将适用于此类应用程序。
