Currently, I am utilizing angular7 with loopback. While I can successfully retrieve data, I am unsure how to receive error messages and response statuses. It would be helpful for me to understand what my response code is at the time of the request.
Output of Data
[
{
"name": "karthik",
"lastname": "Selvakumar",
"course": "BE",
"year": "IV",
"id": 2
}
]
To retrieve the response code from the HttpResponse, you can use the following code snippet:
import { Component, OnInit } from '@angular/core';
import { HttpClient } from "@angular/common/http";
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent implements OnInit {
status;
constructor(private http: HttpClient) {}
ngOnInit() {
this.http.get('https://jsonplaceholder.typicode.com/posts?page=0', {observe: 'response'})
.toPromise().then((response) => {
this.status = response.status;
})
}
}
