Question

我有一个Android应用程序试图将用户注册到django服务器，用json发送POST请求。

我得到的响应代码是500 INTERNAL SERVER ERROR

Android代码：

httpClient = new DefaultHttpClient();
registerUserRequest = new HttpPost("http://10.100.102.9:8000/users/register");

public void registerUser(){


    Map<String, String> userMap = new HashMap<String, String>();
    userMap.put("username", "UserName");
    userMap.put("password", "12345");
    userMap.put("first_name", "first");
    userMap.put("last_name", "last");

    JSONObject obj=new JSONObject(params);

    StringEntity se = new StringEntity(obj.toString());
    registerUserRequest.setEntity(se);
    registerUserRequest.setHeader("Content-type", "application/json");
    new executeRequest().execute(registerUserRequest);
}

 private class executeRequest extends AsyncTask<HttpRequest, Void, Integer>
 {

    @Override
    protected Integer doInBackground(HttpRequest... params) {
        // TODO Auto-generated method stub
        HttpRequest request = params[0];
        int responseCode = -1;
        ResponseHandler responseHandler = new BasicResponseHandler();
        HttpResponse response;
        try {
            response = httpClient.execute(registerUserRequest,
                    responseHandler);

            Log.d("Response of REGISTER_USER request", response.toString());
            responseCode = response.getStatusLine().getStatusCode();
        } catch (ClientProtocolException e) {
            // This exception raised
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return responseCode;
    }

}

引发的异常是AsyncTask中的ClientProtocolException。

Django代码：

class UserViewSet(viewsets.ReadOnlyModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

    @list_route(methods=['post'])
    def register(self, request):
        serializer = UserSerializer(data=request.DATA)
        if serializer.is_valid():
            user = User.objects.create_user(
                username = serializer.init_data['username'],
                password = serializer.init_data['password'],
                first_name = serializer.init_data['first_name'],
                last_name = serializer.init_data['last_name'],
            )

            return Response(serializer.data, status=status.HTTP_201_CREATED)
        else:
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

网址很好我测试了 - “http://10.100.102.9:8000/users/register”

错误：我得到的响应代码是500 INTERNAL SERVER ERROR

任何想法为什么会发生这种情况？

谢谢！

500 INTERNAL SERVER ERROR表示服务器端代码中的错误，而不是移动端。检查服务器端发生的异常。

android - 用json发送POST给django服务器
