You need to use HttpClient
not HttpClientModule
to make an http request.
In app.module.ts, import HttpClientModule
(see “imports” below):
import { HttpClientModule } from '@angular/common/http';
@NgModule({
imports: [
HttpClientModule,
...
],
...
})
export class AppModule { }
Then, import HttpClient
in app.component.ts:
import { HttpClient } from '@angular/common/http';
Now, change your AppComponent Ctor from
constructor(private http: HttpClientModule){};
to
constructor(private http: HttpClient){};
