POST service in ASP.NET Core WebAPI - asp.net-core

Question

I'm trying to write very simple multi-platform app (iOS & Android) in visual studio. This app uses web service, uploaded on my web hosting.
This is code that call WebAPI (get & post):
async void post_async(object sender, System.EventArgs e)
{
Console.WriteLine("POST");
try
{
HttpClient httpClient = new HttpClient();
var BaseAddress = "https://mywebsite";
var response = await httpClient.PostAsync(BaseAddress, null);
var message = await response.Content.ReadAsStringAsync();
Console.WriteLine($"RESPONSE: " + message);
}
catch (Exception er)
{
Console.WriteLine($"ERROR: " + er.ToString());
}
}
async void get_async(object sender, System.EventArgs e)
{
try
{
HttpClient httpClient = new HttpClient();
var BaseAddress = "https://mywebsite";
var response = await httpClient.GetAsync(BaseAddress);
if (response.IsSuccessStatusCode)
{
var content = await response.Content.ReadAsStringAsync();
Console.WriteLine($"RESPONSE: " + content);
}
}
catch (Exception er)
{
Console.WriteLine($"ERROR: " + er.ToString());
}
}
This is very simple code for Web Api:
[HttpGet]
public ActionResult<string> Get()
{
return "get method ok";
}
[HttpPost]
public ActionResult<string> Post()
{
return "post method ok";
}
Very strange issue because for every void I always obtain "get method ok". So "get" is ok, but I don't understand why I cannot call post method.
I tried to use Postman: same issue.
I'm using this very simple code:
[ActionName("getmet")]
public ActionResult<string> getmet()
{
return "get method ok";
}
[ActionName("postmet")]
public ActionResult<string> postmet()
{
return "post method ok";
}
Now of course I can call https://mywebsite/getmet or postmet and it works using postman.
If I use [HttpPost] for postmet method, on Postman I get "404 not found". Why?

Answer 1

var BaseAddress = "https://mywebsite"; //
URL hits get method by difualt, thats means works as https://mywebsite/Get where as your actual post method URL is https://mywebsite/Post
instead of calling a different method use code like below.
[HttpPost]
[HttpGet]
public ActionResult<string> Get()
{
return "method ok";
}
OR you can use API ROUTE
OR
[AcceptVerbs(HttpVerbs.Get|HttpVerbs.Post)]
