Question

我有这个：

handlers.py

class ChatHandler(BaseHandler):
    model = ChatMsg
    allowed_methods = ('POST','GET')

    def create(self, request, text):
        message = ChatMsg(user = request.user, text = request.POST['text'])
        message.save()
        return message

template.html

    ...
    <script type="text/javascript">
    $(function(){
        $('.chat-btn').click(function(){
            $.ajax({
                url: '/api/post/',
                type: 'POST',
                dataType: 'application/json',
                data: {text: $('.chat').val()}
            })
        })
    })
    </script>
    ...

API / urls.py

chat_handler = Resource(ChatHandler, authentication=HttpBasicAuthentication)
urlpatterns = patterns('',
    ....
    url(r'^chat/$', chat_handler, {'emitter_format': 'json'}),
)

为什么，但ChatHandler中允许使用POST方法？ GET方法正在运行。是错误，还是我的代码错了？

即使你没有在你的问题中包含这个代码，我在你给你的github中找到了它的评论......

您正在映射到不允许POST请求的处理程序

urls.py :: snip ::

post_handler = Resource(PostHandler, authentication=auth)
chat_handler = Resource(ChatHandler, authentication=auth)
urlpatterns = patterns('',
    url(r'^post/$', post_handler , { 'emitter_format': 'json' }),
    url(r'^chat/$', chat_handler, {'emitter_format': 'json'}),
)

<强> handlers.py

# url: '/api/post'
# This has no `create` method and you are not 
# allowing POST methods, so it will fail if you make a POST
# request to this url
class PostHandler(BaseHandler):
    class Meta:
        model = Post

    # refuses POST requests to '/api/post'
    allowed_methods = ('GET',)


    def read(self, request):
        ...

# ur;: '/api/chat'
# This handler does have both a POST and GET method allowed.
# But your javascript is not sending a request here at all.
class ChatHandler(BaseHandler):
    class Meta:
        model = ChatMsg
    allowed_methods = ('POST', 'GET')

    def create(self, request, text):
        ...

    def read(self, request):
        ...

您的javascript请求正在发送到'/api/post/'，该PostHandler被路由到'/api/chat/'。我觉得你期望它去聊天处理程序。这意味着您需要将javascript请求网址更改为Meta，或将代码移至您预期的处理程序。

此外，您在处理程序中设置错误的模型。它不需要class PostHandler(BaseHandler): model = Post class ChatHandler(BaseHandler): model = ChatMsg嵌套类。它应该是：
