如何返回扭曲的json响应？

Question

When I am using django: I always do

return HttpResponse(json.dumps(result), mimetype='application/json')

How can I do this in twisted? Official document do not say this.

document here

Only Serving WSGI Applications can set mimetype .But I want to process GET and POST There is no more example, and I searched with nothing found.

from twisted.web import resource
class MyGreatResource(resource.Resource):
    def render_GET(self, request):
        return "xxxx"

It return raw string

Answer 1

Encoded JSON is a (byte) string.

If your question is "How do I set the Content-Type of the response to application/json ?" then the answer is:

request.responseHeaders.addRawHeader(b"content-type", b"application/json")
