You're not following standard Web API routes in the client application which is why a 404 is returned. Just use Swagger to find the URL....

app.UseSwagger(); app.UseSwaggerUI();

or learn how routing works by reading the reference documentation.

Routing to controller actions in ASP.NET Core

To be clear, you defined the base URL as...

string jwturl = "https://visitsapi.azurewebsites.net/api/Auth/";

Then the code tried to call....

HttpResponseMessage Res = await client1.GetAsync("api/Login");

The URL ends up being.

https://visitsapi.azurewebsites.net/api/Auth/api/Login

@AgaveJoe

Thanks I fixed the routing issue


            string jwturl = "https://visitsapi.azurewebsites.net/api/";
            using (var client1 = new HttpClient())
            {

                client1.BaseAddress = new Uri(jwturl);

                client1.DefaultRequestHeaders.Clear();
                client1.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                HttpResponseMessage Res = await client1.GetAsync("Auth");

                if (Res.IsSuccessStatusCode)
                {
                    //Storing the response details recieved from web api   
                    var JWTResponse = Res.Content.ReadAsStringAsync().Result;

                    TempData["Token"] = JWTResponse;


                }

I get response as

{"token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2OTU3NTMyNDgsImlzcyI6Imh0dHBzOi8vbG9jYWxob3N0OjUwMDEiLCJhdWQiOiJodHRwczovL2xvY2FsaG9zdDo1MDAxIn0.b-veSe1W320TY3v_CD_JuBLcbkqKgZsD194rokJ6uL8"}

But I just need the response to be

"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2OTU3NTMyNDgsImlzcyI6Imh0dHBzOi8vbG9jYWxob3N0OjUwMDEiLCJhdWQiOiJodHRwczovL2xvY2FsaG9zdDo1MDAxIn0.b-veSe1W320TY3v_CD_JuBLcbkqKgZsD194rokJ6uL8"

Please suggest

the response is json. use the json serializer of your choice and deserialize. the class would be:

public class JwtRs { public string token {get; set;} }

or the simpler:

if (Res.IsSuccessStatusCode) { //Storing the response details recieved from web api var jwtRs = res.Content.ReadFromJsonAsync<JwtRs>(); TempData["Token"] = jwtRs.token; }

again a Jwt token request should be a POST with credentials.

I'm a little confused by your question because your code specifically returns a JSON response. If you don't want a JSON object then why are you returning one?

return Ok(new AuthenticatedResponse { Token = tokenString });

If you just want to return the token, which is a string, then just return a string. You'll need to change the action's return type to a string too.

return tokenString;

I recommend sticking with the JSON object and simply deserialize the AuthenticatedResponse type in the client. Deserializing JSON into a C# type is a standard pattern and covered in any getting started tutorial.

Thanks @AgaveJoe and @Bruce (SqlWork.com)


                if (Res.IsSuccessStatusCode)
                {
                    //Storing the response details recieved from web api   
                    string json = await Res.Content.ReadAsStringAsync();

                    // Parse the JSON response to extract the address
                    dynamic data1 = Newtonsoft.Json.JsonConvert.DeserializeObject(json);
                    string  code = data1.token;
                  
                    TempData["Token"] = code;
                 

                }
