Using http.get to get page from frontend
It's possible to use Angular 8 http.get to get a page from the frontend itself ?
My local frontend url: https://192.168.0.177:4200/
I tried in a service:
test(): Observable<string> {
return this.http
.get<string>(`https://192.168.0.177:4200/ping`)
.pipe(catchError(this.processHTTPMsgService.handleError));
}
but I got a 404:
Console:
GET https://192.168.0.177:4200/ping 404 (Not Found)
ERROR 404 - Not Found <!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot GET /ping</pre>
</body>
</html>
This has an hardcoded url because it's just a test. My FE is on port 4200 and my backend in 3443.
https://192.168.0.177:4200/ping url load correctly if I put it directly on browser.
The /ping url is an Angular component with only a PING string inside:
ping.component.ts:
import { Component } from '@angular/core';
@Component({
selector: 'app-ping',
templateUrl: './ping.component.html'
})
export class PingComponent {
constructor() { }
}
ping.component.html:
PING
I call service.test() from some other component this way:
test(): void {
this.myService.test().subscribe(test=>{
console.log('test', test); // Should result in PING
})
}
I also tried with axios:
axios.get('https://192.168.0.177:4200/ping').then(ping=>{
console.log('ping', ping);
}).catch(err=>{
console.log('ping error', err);
});
with same result.
What I'm trying to do here ? I develop an Angular video application that shows live video stream that take too long. It has a Keycloak login that has an idle limit. So I'm trying to simulate user action in order to make keycloak know it's alive and don't logout automatically.
Any help appreciated. Thanks.
