HTTP Post - how to get the Id from the HTTP Post response and NOT from context.SaveChanges

Question

private void AddService()
{
Service service = new Service();
service.ServiceName = newService.ServiceName;
service.RoleId = 8;
service.IsProcedure = false;
service.ShortForm = newService.ServiceName;
service.Maincat = newService.MainCat;
service.Subcat = null;
service.Strength = null;
service.Package = null;
service.Size = null;
service.Note = null;
string baseUrl = "https://localhost:44384";
var httpClient = _clientFactory.CreateClient("ServerAPI");
httpClient.DefaultRequestHeaders.Add("Accept", "application/json");
var response = httpClient.PostAsJsonAsync($"{baseUrl}/api/Service/AddNewService", service);

    //need to do stuff here where I need the newly created ServiceId

}

How do I get the Id of the newly inserted record from <response>?

Answer 1

Hi, @MyLadys-4900,
You should confirm one things that it will return the newly created Service entity from the HTTP Post response.
You could get jsonString from response.

    var result = response.Result;  

string jsonString = result.Content.ReadAsStringAsync().Result;
Then you can deserialize your object from json string:

Service returnService = JsonSerializer.Deserialize<Service>(jsonString);

Now, you can get Id from returnService.Id.

Answer 2

Check your code....

private void AddService()
{Service service = new Service();

Are you in need of a dot at the key\value pair,
{
Service.service = NewService()
}

....and check your formatting...?
Consistency will make your code easier to debug, as well as easier for others to read @MyLadys-4900
Alt/Option + F10 will tab to the formatting toolbar.

Answer 3

There was indeed something wrong with what I did. Got that fixed.

This is what I ended up with:

    var response = await httpClient.PostAsync($"{baseUrl}/api/Service/AddNewService", content);
    var data = await response.Content.ReadAsStringAsync();
    Service result = new Service();

    if (response.IsSuccessStatusCode)
    {
        result = JsonSerializer.Deserialize<Service>(data);    
    }
    else 
    {
        errorMessage = data;
    }

    if (result != null) { // do stuff }

This all works, thanks miwan2!

Answer 4

This targets NET5 so I have Swagger to look at to see what it thinks is the route:
/api/Service/AddNewService

Answer 5

System.InvalidOperationException: No route matches the supplied values

It said the url {baseUrl}/api/Service/AddNewService", service); you post doesn't exist. Please check the route firstly.
