When working on an Angular implementation, I am in the process of sending an HTTP request to the back end server.
To set up my app.module file, I imported {HttpClientModule} from '@angular/common/http' into the module and included it in the imports array to ensure its availability throughout the application.
Next step involves using the get method provided by HttpClient to fetch the necessary data from the server - that's my game plan.
An important question arises regarding determining the data type that will be returned by the server.
The component code snippet looks something like this...I've trimmed out unnecessary details for brevity.
@Component(...)
export class MyComponent implements OnInit {
// results: string[]; // Unsure about this
constructor(private http: HttpClient) {}
ngOnInit(): void {
url = 'http://example.com/authentication/get-username.php';
http
.get<MyJsonData>(url)
.subscribe...
}
My query is - what should I specify as the data type where it currently shows ? in the above code?
A bit more context:
The URL response typically resembles the following format:
{"wordpress_username":"admin_joe","user_role":"admin"}In cases where no user is logged in, the response could look like this:
{"wordpress_username":"","user_role":""}Here we are dealing with a structure like {"x":"y", "j":"k"} which is essentially a JSON string but also acts as an object.
This situation is where my confusion sets in.
Would creating an interface for this scenario be beneficial? If so, how should the interface be defined?
