ASP.net REST API返回本地或天蓝色的不同数据

Question

So I built this API that returns data about devices. When I run this project localy, the result my requests give me are correct:

[
  {
    "Id": "1",
    "Name": "x1",
    "LocationName": "Floor 2"
  },
  {
    "Id": "2",
    "Name": "x2",
    "LocationName": "Floor 2"
  }
]

When I publish this project to Azure and make the exact same request this is what I get:

 "Request": {
    "AlwaysMultipartFormData": false,
    "JsonSerializer": {
      "DateFormat": null,
      "RootElement": null,
      "Namespace": null,

    },

      }
    ],
    "Files": [],
    "Method": 0,
    "Resource": "devices",
    "RequestFormat": 1,

        "MemberType": 8,

    },
    "DateFormat": null,

  },
  "ContentType": "application/json; charset=utf-8",
  "ContentLength": -1,
  "ContentEncoding": "",
  "Content": "[\r\n  {\r\n    \"$id\": \"1\",\r\n    \"id\": \"1\",\r\n    \"name\": \"x1\",\r\n    \"deviceTypeName\": \"Brickstream\",\r\n    \"lastSeen\":....

It looks like a string representation of a HttpResponseMessage object. As you can see under contents, thats the same output of when I did the request locally. Now is the question, what am I doing wrong here?

Code:

[Route("")]
public HttpResponseMessage GetAllDevicesLocation(string location)
{
    var request = new RestRequest();
    request = new RestRequest($"devices", Method.GET);
    IRestResponse response = client.Execute(request);

    string serializedItemsFromBackend = response.Content;
    var deserializedItemsFromBackend = JsonConvert.DeserializeObject<List<DeviceModels>>(serializedItemsFromBackend);
    List<DeviceModels> list = new List<DeviceModels>();

    foreach (DeviceModels device in deserializedItemsFromBackend)
    {
        if (device.LocationName.Equals(location))
        {
            list.Add(device);
        }
    }
    if (list.Count > 0)
    {
        return CreateResponse(JsonConvert.SerializeObject(list));
    }
    return Request.CreateResponse(HttpStatusCode.NotFound, "Devices in that area wasn't found.");
}

I can swear that this worked yesterday. My other endpoints work just fine..

EDIT This endpoint gives me correct results both locally and on azure::

   [Route("{name}")]
        public HttpResponseMessage GetDevice(string name)
        {
            var request = new RestRequest();
            request = new RestRequest($"devices", Method.GET);
            IRestResponse response = client.Execute(request);

            string serializedItemsFromBackend = response.Content;
            var deserializedItemsFromBackend = JsonConvert.DeserializeObject<List<DeviceModels>>(serializedItemsFromBackend);

            foreach (DeviceModels device in deserializedItemsFromBackend)
            {
                if (device.Name.Equals(name))
                {
                    return CreateResponse(JsonConvert.SerializeObject(device));
                }
            }
            return Request.CreateResponse(HttpStatusCode.NotFound, "Device with that name wasn't found.");
        }

I create the following sample to reproduce the issue on my side, the sample that returns an HttpResponseMessage works fine both on local and Azure website. You could create a new Web API project to convert the return value directly into an HTTP response message and publish the project to a new Azure website as I did to check if it works as expected.

My controller action

public class ValuesController : ApiController
{
    public HttpResponseMessage Get()
    {
        List<DeviceModels> list = new List<DeviceModels>();
        list.Add(new DeviceModels() { Id = "1", Name = "x1", LocationName = "Floor 2" });
        list.Add(new DeviceModels() { Id = "2", Name = "x2", LocationName = "Floor 2" });

        HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, JsonConvert.SerializeObject(list));

        return response;
     }
}

If possible, you could modify your controller action to return json string directly.

public string GetAllDevicesLocation(string location)
{
    //code logic

    return JsonConvert.SerializeObject(list);
}

Besides, please make sure you still could get correct result from action GetAllDevicesLocation from your local project. And you could remote debug your web app to trace the variable response and check if the method CreateResponse(JsonConvert.SerializeObject(list)) works as it run on your local project.

If you could provide us a sample that could reproduce the issue, which will help us find and fix the issue.
