Menu
I need to create a component that displays the content of another webpage.
So for instance if I have the site of stackoverflow, I would like to create a component that does a http request and displays the content through my app. By the way, the external website is just django-rest-swagger and to access it, I need to include a header everytime I access it. So, when I make the request for the external site content I need to inlclude the header x-forwarded-host.
<div>
<html> CONTENT OF EXTERNAL WEBSITE </html>
</div>
thank you

if you want to insert HTML elements or other components in a component, then you do that using the concept of content projection. In Angular, you achieve content projection using < ng-content >< /ng-content >. You can make reusable components and scalable applications by properly using content projection.
To create a component using the Angular CLI: From a terminal window, navigate to the directory containing your application. Run the ng generate component <component-name> command, where <component-name> is the name of your new component.
Components are the most basic UI building block of an Angular app. An Angular app contains a tree of Angular components. Angular components are a subset of directives, always associated with a template. Unlike other directives, only one component can be instantiated for a given element in a template.
@Component({
selector: ...
template: `<div [innerHTML]="fetchedHtml"></div>
})
export class ExternalHtml {
constructor(http:Http) {
var headers = new Headers();
headers.append('x-forwarded-host', 'foo');
http.get('someUrl', {headers: headers}).subscribe(response => {
this.fetchedHtml = response.json();
}
}

Alternatively you can also use an iframe to display the fetched HTML.
