python - 如何使用 Django 活塞以文本/纯文本形式返回响应？

Question

我不想序列化任何东西。我只想返回相当于HttpResponse(blah)

Answer 1

听起来你想要一个字符串发射器，而不是内置的 JSONEmitter、XMLEmitter 等之一。

查看发射器的文档：https ://bitbucket.org/jespern/django-piston/wiki/Documentation

以及这里现有的发射器定义： https ://bitbucket.org/jespern/django-piston/src/c4b2d21db51a/piston/emitters.py

纯文本发射器的定义可能如下所示：

from piston.emitters import Emitter
from piston.utils import Mimer    

class TextEmitter(Emitter):
    def render(self, request):
        return self.construct()
Emitter.register('text', TextEmitter)
Mimer.register('text', None, ('text/plain',))

您将获得资源以在 urls.py 中使用此发射器，如下所示：

urlpatterns = patterns('',
   url(r'^blogposts$', resource_here, { 'emitter_format': 'text' }),
)

Answer 2

To add on to user85461's answer, when you make a text emitter, you'll want to also make a text Mimer. I wrote the following code with works with Piston 0.2.2

from piston.emitters import Emitter
from piston.utils import Mimer

class TextEmitter(Emitter):
    def render(self, request):
        return self.construct()
Emitter.register('text', TextEmitter, ('text/plain',))
Mimer.register(lambda x: QueryDict(x), ('text/plain',))

Add this snippet somewhere that will get run before your handlers. I put it in my API urls.py above where I created my Resources with

resource_handler = Resource(handler=SomeHandler)

在你看来：

class HttpResponsePlain(django.http.HttpResponse):

    def serialize(self):            return self.content
    def serialize_headers(self):    return ''

return HttpResponsePlain(content = 'That is plain text response!')
