I have a .net core 3.1 api project and I need to get a single vehicle back by using the id. I have made the models to match the data from the Api.

This is what I have so far...

    public class SamsaraGpsVehicleInfo
    {
        [JsonPropertyName("externalIds")]
        public ExternalIds ExternalIds { get; set; }

        [JsonPropertyName("gateway")]
        public Gateway Gateway { get; set; }

        [JsonPropertyName("harshAccelerationSettingType")]
        public string HarshAccelerationSettingType { get; set; }

        [JsonPropertyName("id")]
        public string Id { get; set; }

        [JsonPropertyName("licensePlate")]
        public string LicensePlate { get; set; }

        [JsonPropertyName("make")]
        public string Make { get; set; }

        [JsonPropertyName("model")]
        public string Model { get; set; }

        [JsonPropertyName("name")]
        public string Name { get; set; }

        [JsonPropertyName("notes")]
        public string Notes { get; set; }

        [JsonPropertyName("serial")]
        public string Serial { get; set; }

        [JsonPropertyName("vin")]
        public string Vin { get; set; }

        [JsonPropertyName("year")]
        public string Year { get; set; }

        [JsonPropertyName("vehicleRegulationMode")]
        public string VehicleRegulationMode { get; set; }

        [JsonPropertyName("createdAtTime")]
        public DateTime CreatedAtTime { get; set; }

        [JsonPropertyName("updatedAtTime")]
        public DateTime UpdatedAtTime { get; set; }
    }

    public class ExternalIds
    {
        [JsonPropertyName("samsara.serial")]
        public string SamsaraSerial { get; set; }

        [JsonPropertyName("samsara.vin")]
        public string SamsaraVin { get; set; }
    }

    public class Gateway
    {
        [JsonPropertyName("serial")]
        public string Serial { get; set; }

        [JsonPropertyName("model")]
        public string Model { get; set; }
    }

    public class SamsaraGpsVehicleList
    {
        [JsonPropertyName("data")]
        public ICollection<SamsaraGpsVehicleInfo> Data { get; set; }
    }

Which I make a call with my client like so:

        public async Task<ICollection<SamsaraGpsVehicleInfo>> GetVehicles()
        {
            try
            {
                var result = await _client.GetAsync("fleet/vehicles");

                if (result.IsSuccessStatusCode)
                {
                    var list = await result.Content.ReadAsAsync<SamsaraGpsVehicleList>();
                    return list.Data;
                }
                else
                {
                    return null;
                }
            }
            catch
            {
                return null;
            }
        }

This returns a nice formatted response when I call it from my controller code:

        [HttpGet("samsara")]
        public async Task<IActionResult> GetVehicles(
            [FromServices] SamsaraGpsService samsaraGps)
        {
            var results = await samsaraGps.GetVehicles();

            return Ok(results);

and my result is this JSON:

        "externalIds": {
            "samsaraSerial": null,
            "samsaraVin": null

        "updatedAtTime": "2021-10-13T17:10:56Z"
    }
]

which is perfect.

However I need to get a single vehicle. So I have this code:

        public async Task<SamsaraVehicle> GetVehicleById(string id)
        {
            try
            {
                var result = await _client.GetAsync($"fleet/vehicles/{id}");

                if (result.IsSuccessStatusCode)
                {
                    var vehicle = await result.Content.ReadAsAsync<SamsaraVehicle>();

                    return vehicle;
                }
                else
                {
                    return null;
                }
            }
            catch
            {
                return null;
            }
        }

and this model for the vehicle:

    public class SamsaraVehicle
    {
        [JsonPropertyName("id")]
        public string Id { get; set; }

        [JsonPropertyName("name")]
        public string Name { get; set; }

        [JsonPropertyName("vin")]
        public string Vin { get; set; }

        [JsonPropertyName("serial")]
        public string Serial { get; set; }

        [JsonPropertyName("make")]
        public string Make { get; set; }

        [JsonPropertyName("model")]
        public string Model { get; set; }

        [JsonPropertyName("year")]
        public string Year { get; set; }

        [JsonPropertyName("harshAccelerationSettingType")]
        public string HarshAccelerationSettingType { get; set; }

        [JsonPropertyName("notes")]
        public string Notes { get; set; }

        [JsonPropertyName("licensePlate")]
        public string LicensePlate { get; set; }

        [JsonPropertyName("externalIds")]
        public ExternalIds ExternalIds { get; set; }

        [JsonPropertyName("gateway")]
        public Gateway Gateway { get; set; }

        [JsonPropertyName("vehicleRegulationMode")]
        public string VehicleRegulationMode { get; set; }
    }

    public class SamsaraSingleVehicle
    {
        [JsonPropertyName("data")]
        public ICollection<SamsaraVehicle> Data { get; set; }
    }

However I can not figure out how to get this vehicle back by id. If anyone could help I would greatly appreciate it!

CodePudding user response：

I recommand you modify your codes:

var vehicle = await result.Content.ReadAsAsync<SamsaraVehicle>();

to

var jsonstring = await result.Content.ReadAsStringAsync();
var obj = JsonSerializer.Deserialize<SamsaraVehicle>(jsonstring);

When you debug, you would check the jsonstring :

then you could modify the propery of the model accroding to the string
