C＃HttpClient PostAsync无法与Django Rest框架一起使用

Question

in Django (DRF)

in test.views.py

class TestAPIView(APIView):

    permission_classes = (AllowAny,)
    def post(self, request, format=None):
        print(request.data)
        return Response(request.data)

in test.urls.py

from django.conf.urls import url
from .views import TestAPIView

urlpatterns = [
    url(r'^test/$', view=TestAPIView.as_view()),
]

as you can see, my test url should return the post data. and which does works well in browsable api and Unity WWW(something like httpclient which unity provides).

but it wont work with HttpClient PostAsync(or SendAsync either)

this is my C# code

in Xamarin / C#

    Post newPost = new Post { Title = "asdfasfa", Content = "asdfasffasf" };

    var content = JsonConvert.SerializeObject(newPost);

    Debug.WriteLine(content);

    var response = await _client.PostAsync("http://127.0.0.1:8000/test/", new StringContent(content));

    var responseString = await response.Content.ReadAsStringAsync();

    Debug.WriteLine(responseString);

and the results from the console....

in C# Console

the commented string was written by me. not from the console

{"Id":0,"Title":"asdfasfa","Content":"asdfasffasf"} // <- this is the sent data.
Thread started:  #6
Thread started:  #16
Thread started:  #17
{} // <- and the received data

and...

in Django(DRF) Console

[26/Feb/2017 13:37:34] "POST /test/ HTTP/1.1" 200 2
<QueryDict: {}>

where did my post datas gone??? django received <QueryDict: {}>

and this only happens for httpclient. and maybe only with django. i tested it with => https://jsonplaceholder.typicode.com/posts and the post creation just worked fine.

It could be a Django problem, could be a C# problem, I don't know... help please!

ps?. HttpWebRequest just works fine too.

我根本不了解C＃，但根据其他帖子（ 对Webapi的httpclient调用以发布不起作用的数据或HttpClient没有发布表单数据 ），您可能需要在StringContent设置更多信息：

StringContent(content, Encoding.UTF8, "application/json")
