Question

the process of extracting data from a request body in Angular 2

After creating a URL for end-users to access, I wanted to retrieve data from the request body when they hit the URL from another module. The process involves fetching the data from the request body, passing it to my service, and then validating the response received.

ngOnInit() {
    this.route.params
    .subscribe((params : Params) => {
        this.email=params['id'];
    });

While I am able to fetch data from the URL itself by using the code above,

I encountered an issue with retrieving data from the request body when users click on the URL. This has made it challenging to pass this data to my service effectively.

The main objective is to retrieve two parameters from the request body accurately.

It's important to note that the code snippet you provided is not a request to an API, so there is no body associated with it.

What you are actually doing here is examining the current route displayed in the address bar of your Angular app. There is no request body involved in fetching data; only the query string parameters visible in the address bar.

Essentially, this.route points to the current route being viewed in the browser within your Angular application.

If you intend to call an API and retrieve data, you will need to create a service for that purpose. Here's an example:

@Injectable() export class StoriesService {

constructor(private http: Http, private constService: ConstantsService) { }

public getStories() {
    this.http
        .get(this.constService.apiBaseUrl + "/stories")
        .subscribe((data: Response) => console.log(data));
}

}

In this instance, the variable data contains the response body returned by the call to [apiBaseUrl]/stories.
