There are two files: "image" and "event".
In controller I write this:
public IActionResult NewEvent([ModelBinder(BinderType = typeof(JsonModelBinder))] DataFromCameraModel @event, IFormFile image) { return Ok(); }
and DataFromCameraModel
public class DataFromCameraModel { public int packetCounter {get;set;} public string Datetime {get;set;} public string plateText {get;set;} }
Hello. I have the same problem. Did you find a solution?
I solved as follows:
[HttpPost("newevent")]
[Consumes("multipart/form-data")]
public IActionResult NewEvent(IFormFile @event, IFormFile image)
{
using (var reader = new StreamReader(@event.OpenReadStream()))
{
eventmodel = JsonConvert.DeserializeObject<DataFromCameraModel>(reader.ReadToEnd());
}
firstchar = eventmodel.plateText[0];
if (eventmodel.plateText.Length == 7 && !Char.IsDigit(firstchar))
{
var imagepath = _truckService.UploadNewEventImage(image);
_truckService.SaveNewEvent(eventmodel,imagepath);
this.HubContext.Clients.All.SendAsync("Refresh", eventmodel);
}
return Ok();
}
public class DataFromCameraModel
{
public string Datetime { get; set; }
public string plateText { get; set; }
}
I solved as follows:
[HttpPost("newevent")] [Consumes("multipart/form-data")] public IActionResult NewEvent(IFormFile @event, IFormFile image) { using (var reader = new StreamReader(@event.OpenReadStream())) { eventmodel = JsonConvert.DeserializeObject<DataFromCameraModel>(reader.ReadToEnd()); } firstchar = eventmodel.plateText[0]; if (eventmodel.plateText.Length == 7 && !Char.IsDigit(firstchar)) { var imagepath = _truckService.UploadNewEventImage(image); _truckService.SaveNewEvent(eventmodel,imagepath); this.HubContext.Clients.All.SendAsync("Refresh", eventmodel); } return Ok(); } public class DataFromCameraModel { public string Datetime { get; set; } public string plateText { get; set; } }
Thanks for the reply. So you did not actually use "JsonModelBinder"!
didnt use, you can get data easily with this:
using (var reader = new StreamReader(@event.OpenReadStream()))
{
eventmodel = JsonConvert.DeserializeObject<DataFromCameraModel>(reader.ReadToEnd());
}

Thank you. ok.
