How can I pass object from WEB API CORE 2.0 to Angular 7?
Please give me example.
I got object = null in Angular 7 and don't understand why.
Web Api Controller
[HttpGet]
[Produces("application/json")]
[Route("ListArtists")]
public JsonResult ListArtists()
{
var artists = _context.Artists.ToList();
return Json(new { results = artists });
}
POCO Classes
public class Artist
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int id
{
get; set;
}
public FakeData fake { get; set; }
}
public class FakeData
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int id { get; set; }
public string name { get; set; }
}
Angular models
export class Artist {
id: number;
fake: FakeData;
}
export class FakeData {
id: number;
name: string;
}
Getting data in angular using observable
getArtistsList(): Observable<Artist> {
return this.http.get<Artist>(this.myAppUrl + 'api/ArtistsLibrary/ListArtists');
}
component
artists_count: number;
artists: Artist;
ngOnInit() {
this.form = this.fb.group({ searchText: [null, null] });
this.LoadData();
}
LoadData() {
console.log("LoadData");
console.log("checkedList=" + this.checkedList);
const genre_storage = sessionStorage.getItem("genre");
debugger;
this._artistsService
.getArtistsList()
.pipe()
.subscribe((artists: Artist) => {
this.artists = artists;
this.artists_count = artists.length;
});
}

You can create a method in webapi controller to pass the object after serializing into json format.
In angular, you can call that route using angular service to get that json. The json can be mapped into your required javascript object in angular.
This way you are able to pass C# object from asp.net core into javascript object in angular.
[HttpGet]
[Produces("application/json")]
[Route("ListArtists")]
public IActionResult ListArtists()
{
var artists = _context.Artists.ToList();
return Ok(artists);
}
Try checking if the url endpoint is giving you json data. It is a parsing problem.

I have changed my answer. Try calling the url from browser or postman. If it gives the data check the format it is giving. Since you are putting array ofArtist,your json result should be enclosed with.

Postman is correct for both IActionresult snd Jsonresult. Problem that Angular returns object Fakedata = null.
