I have this in my controller:
[
HttpPost]
public async Task<ActionResult> UpdateCalendarEntry(CalendarEntry model)
{
try
{
model.LabelColor = "blue";
var result = await repo.AddCalendarEntry(model);
if(result == null)
{
return StatusCode(StatusCodes.Status204NoContent, "Cannot Do It!");
}
return apiResult.Send200(result);
}
catch (Exception ex)
{
return apiResult.Send400(ex.Message);
}
}
I get the response in my Service in Blazor WASM like so:
using var response = await httpClient.SendAsync(request);
var content = await response.Content.ReadAsStringAsync();
// auto logout on 401 response
if (response.StatusCode == HttpStatusCode.Unauthorized)
{
navigationManager.NavigateTo("login");
return default;
}
if(response.StatusCode == HttpStatusCode.BadRequest)
{
await helperService.InvokeAlert("Bad Request", $@"{response.ReasonPhrase}", true);
}
if(response.StatusCode == HttpStatusCode.NoContent)
{
var x = response.Content.ReadAsStringAsync();
await helperService.InvokeAlert("Bad Request", $@"{response.ReasonPhrase}", true);
}
// throw exception on error response
if (!response.IsSuccessStatusCode)
{
//var error = await response.Content.ReadFromJsonAsync<Dictionary<string, string>>();
//throw new (error["message"]);
return default;
//throw new ApplicationException
// ($"The response from the server was not successful: {response.ReasonPhrase}, "
// $"Message: {content}");
}
I need to get the reply from the controller on "No Content" the message "Cannot Do It!". I am trying the ReasonPhrase, but I don't know how to put the error there.

You can't return any value when you retun NoContext response. This is the only way I see to add your message to a response header. This code was tested using VS
....
if(response.StatusCode == HttpStatusCode.NoContent)
{
var reason= response.Headers.FirstOrDefault(h=> h.Key=="Reason");
if(reason!=null)
await helperService.InvokeAlert("Bad Request", $@"{reason.Value}", true);
}
