WebDispatch 1.3

发送并生成url

使用url模式发送。

HELO应用示例：

>>> from webob.dec import wsgify
>>> @wsgify
... def greeting(request):
...     return "Hello, %s" % request.urlvars['name']

创建和配置URL分发程序：

>>> from webdispatch import URLDispatcher
>>> dispatcher = URLDispatcher()
>>> dispatcher.add_url('top', '/hello/{name}', greeting)

作为wsgi应用程序调用dispatcher：

>>> from webob import Request
>>> req = Request.blank('/hello/webdispatch')
>>> res = req.get_response(dispatcher)
>>> res.body
b'Hello, webdispatch'

>>> @wsgify
... def with_pathinfo(request):
...     return "Hello, %s" % request.path_info
>>> dispatcher.add_url('top', '/with_pathinfo/*', with_pathinfo)
>>> req = Request.blank('/with_pathinfo/this/is/pathinfo')
>>> res = req.get_response(dispatcher)
>>> res.body
b'Hello, this/is/pathinfo'

>>> @wsgify
... def add(request):
...     result = request.urlvars['v1'] + request.urlvars['v2']
...     return "result, %d" % result
>>> dispatcher.add_url('add', '/add/{v1:int}/{v2:int}', add)
>>> req = Request.blank('/add/1/2')
>>> res = req.get_response(dispatcher)
>>> res.body
b'result, 3'

DEFAULT_CONVERTERS = {
    'int': int,
    'date': lambda s: datetime.strptime(s, '%Y-%m-%d'),
    'date_ym': lambda s: datetime.strptime(s, '%Y-%m'),
}

行动调度

actionDispatcher从urlvars调用操作名为的对象方法。

操作处理程序类：

>>> class MyHandler(object):
...     @wsgify
...     def greeting(self, request):
...         return "Hello"

创建和配置ActionDispatcher:

>>> from webdispatch import ActionDispatcher
>>> actiondispatcher = ActionDispatcher()
>>> actiondispatcher.register_actionhandler(MyHandler)

添加名为action:

>>> dispatcher.add_url('action_dispatch', '/actions/{action}', actiondispatcher)

调用wsgi appclication.：

>>> req = Request.blank('/actions/greeting')
>>> res = req.get_response(dispatcher)
>>> res.body
b'Hello'

方法调度

通过http方法restfully调度。

使用register_appdecorator:

>>> from webdispatch import MethodDispatcher
>>> restapp = MethodDispatcher()
>>> @restapp.register('get')
... @wsgify
... def get_hello(request):
...    return "Get Hello"
>>> @restapp.register('post')
... @wsgify
... def post_hello(request):
...    return "Post Hello"

或者使用registe_app方法：

>>> from webdispatch import MethodDispatcher
>>> restapp = MethodDispatcher()
>>> restapp.register_app('get', get_hello)
>>> restapp.register_app('post', post_hello)

每个应用程序都使用http方法名注册。

调用wsgi应用程序：

>>> req = Request.blank('/')
>>> res = req.get_response(restapp)
>>> res.body
b'Get Hello'

额外环境

DispatchBase接受extra_environ参数。 dispatcher根据请求将该参数添加到wsgi环境中。
