Question

每个人，我最近都在开发服务器-客户端系统，在服务器端，我使用django和restframework与android应用程序进行交互。在客户端，我使用android和改造来从服务器发送和获取数据。当我从服务器获取数据时，一切都很好，但是当我尝试将数据从android发布到django时，它有一些错误。具体来说，它成功将数据发布到服务器，但未在django视图中显示。

我首先使用邮递员测试是否可以将数据发布到URL http://192.168.*.**:8001/api/output，并且可以正常工作，但是当我使用android应用程序将数据发布到http://192.168.*.**:8001/api/output时，它也可以成功发布

这是我的django服务器代码

class OutputInfoView(ModelViewSet):
    serializer_class = OutPutInfoSerializer

    def get_queryset(self):
        return models.OutputInfo.objects.all()

class OutPutInfoSerializer(serializers.ModelSerializer):

    class Meta:
        model = models.OutputInfo
        fields = ['id', 'user', 'lx', 'ly', 'room', 'activity', 'sound']

# router url
routers = routers.DefaultRouter()
routers.register(r'output', views.OutputInfoView,basename='OutputInfo')

urlpatterns = [
    path('', include(routers.urls))
    # path('output', views.OutputInfoView.as_view(), name='output'),
]

在我的android客户端中，我进行了用户改造以发布数据：

public interface JsonPlaceHolderAPI {

    @Headers({"Content-Type: application/json"})
    @POST("output")
    Call<List<Sender>> createUser(@Body RequestBody body);
}

这是主要活动负载

        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

        OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .addInterceptor(loggingInterceptor)
                .build();

        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("http://192.168.*.**:8001/api/")  // restapi的BASE地址
                .addConverterFactory(GsonConverterFactory.create())   // 添加jsonparse
                .client(okHttpClient)
                .build();

        jsonPlaceHolderApi = retrofit.create(JsonPlaceHolderAPI.class);

        createSend();

// send post json data to server
private void createSend(){

        Sender send = new Sender("2","35","43","sdf","gredf","4dfe");
        Gson gson = new Gson();

        String route = gson.toJson(send);
        Log.d("TAG", route);
        RequestBody body = RequestBody.create(okhttp3.MediaType.parse("application/json; charset=utf-8"),route);
        Call<List<Sender>> call = jsonPlaceHolderApi.createUser(body);

        call.enqueue(new Callback<List<Sender>>() {
            @Override
            public void onResponse(Call<List<Sender>> call, Response<List<Sender>> response) {
                if (response.isSuccessful()){
                    showText.setText("successfuly send");

                }else{
                    showText.setText("Code: " + response.code());
                    return;
                }
            }

            @Override
            public void onFailure(Call<List<Sender>> call, Throwable t) {
                showText.setText(t.getMessage());
            }
        });
    }

在完成所有这些步骤之后，我首先使用postman来测试是否可以将数据发布到URL http://192.168.*.**:8001/api/output，并且可以正常工作，但是当我使用android应用程序将发布数据发送到http://192.168.*.**:8001/api/output时，它也可以成功发布，如下所示：

D/OkHttp: --> POST http://192.168.0.11:8001/api/output
D/OkHttp: Content-Type: application/json
    Content-Length: 79
    {"activity":"gredf","lx":"35","ly":"43","room":"sdf","sound":"4dfe","user":"2"}
    --> END POST (79-byte body)
D/OkHttp: <-- 200 OK http://192.168.0.11:8001/api/output/ (94ms)
    Date: Thu, 27 Jun 2019 02:30:55 GMT
    Server: WSGIServer/0.2 CPython/3.7.1
    Content-Type: application/json
    Vary: Accept, Cookie
    Allow: GET, POST, HEAD, OPTIONS
    X-Frame-Options: SAMEORIGIN
    Content-Length: 371
D/OkHttp: [{"id":1,"user":1,"lx":"25","ly":"35","room":"classroom","activity":"walk","sound":"speak"},{"id":2,"user":2,"lx":"12","ly":"79","room":"restroom","activity":"stand","sound":"silence"},{"id":3,"user":1,"lx":"22","ly":"19","room":"restroom","activity":"stand","sound":"silence"},{"id":4,"user":1,"lx":"22","ly":"19","room":"restroom","activity":"stand","sound":"silence"}]
    <-- END HTTP (371-byte body)

恰当地，数据没有成功发送到服务器，我想知道哪里出了问题，我想我已经尽力了。

android将帖子数据发送到Django

改装发布无法成功将json数据发送到django服务器
