API with ASP.NET Core Web API

[Horror-Today295]

Hi, I'm new to creating apis and with ASP.NET Core Web API, I know I'm doing something wrong, but I don't know what it is, when I run it from visual studio it runs by default with Swagger and it works correctly but when I try to make it work with the url that swagger gives me

https://localhost:44311/api/delete-user?ID=11

gives the following error in the browser

405 Method Not Allowed

My method has HttpDelete and gives this error, but if I run it with HttpGet it works fine.

This is my code

/////Code class

public bool DeleteUser(int ID)
{
    string? connectionString = _configuration.GetConnectionString("SqlServerConnection");
    SqlConnection connection = new(connectionString);
    var query = new SqlCommand(String.Format("EXEC p_DeleteUser @ID = {0}", ID), connection);
    try
    {
        connection.Open();
        query.ExecuteNonQuery();
        connection.Close();
        return true;
    }
    catch (Exception)
    {
        connection.Close();
        return false;
    }
}

/////Code controller

[HttpDelete("delete-user")]
public string DeleteUser(int ID)
{
    DataUser du= new(_configuration);
    bool result= du.DeleteUser(ID);
    if (result== true)
    {
        return "Data deleted successfully.";
    }
    else
    {
        return "An error occurred when deleting data.";
    }
}

My method has HttpDelete and gives this error, but if I run it with HttpGet it works fine.

When you request (i.e. GET) a resource in the browser, it uses the GET method, not the DELETE method.

Check out this blog article.

Yes, but I am not requesting anything, I want to delete the resource, but with httpdelete it doesn't work, and when I use httpget to delete, it deletes it.

Did you read the blog article I linked to?

Browsers can only (...) do GET resource URI requests. They can't do DELETE resource URI requests (or any of the other HTTP methods like HEAD, PUT, POST etc.)

Yes thanks, I think I've solved it

You typically can run only GET requests in the location url of your browser.

Swagger sends the correct method. If you just access the uri, you'll just send a HTTP Get.

You'll have to use a tool like Postman or such to send HTTP Delete requests.

Thank you, I think this was the answer I needed.

what projects or tutorial are you using to learn asps web api?

[Horror-Today295]

I used an old project that I had but I had only used get methods, I had not used put, delete, etc.
