I have a .Net API with EF core, i generated the endpoints automatically from the models. Now i have a problem with the put method. when i send my model to the API i get a error 500 response back, when i try it within Swaggers i get an error 400 response. I feel that there’s something wrong with the way i setup my models but i can’t figure out what it exactly is.
API:
group.MapPut("/{id}", async Task<Results<Ok, NotFound>> (int id, User user, DataContext db) =>
{
var affected = await db.User
.Where(model => model.Id == id)
.ExecuteUpdateAsync(setters => setters
.SetProperty(m => m.Id, user.Id)
.SetProperty(m => m.Name, user.Name)
.SetProperty(m => m.Company, user.Company)
.SetProperty(m => m.Department, user.Department)
.SetProperty(m => m.Email, user.Email)
.SetProperty(m => m.Password, user.Password)
);
return affected == 1 ? TypedResults.Ok() : TypedResults.NotFound();
})
.WithName("UpdateUser")
.WithOpenApi();
Front-end:
@code {
[Parameter]
public int? Id { get; set; }
[SupplyParameterFromForm]
public User? user { get; set; }
protected override async Task OnInitializedAsync()
{
if (Id != null)
{
try{
var response = await HttpClient.GetAsync($"https://localhost:7183/api/User/{Id}");
response.EnsureSuccessStatusCode();
var json = await response.Content.ReadAsStringAsync();
user = JsonSerializer.Deserialize<User>(json, new JsonSerializerOptions { PropertyNameCaseInsensitive = true });
}
catch (Exception ex)
{
// Handle error
Console.WriteLine("Error getting user: " + ex.Message);
}
}
else
{
user ??= new();
}
}
void AddUser()
{
if (Id != null)
{
try
{
var client = new HttpClient();
client.BaseAddress = new Uri("https://localhost:7183/api/User");
var json = JsonSerializer.Serialize(user);
var content = new StringContent(json, Encoding.UTF8, "application/json");
var response = client.PutAsync($"User/{Id}", content).Result;
NavManager.NavigateTo("/UserOverview");
}
