I see two ways to do that:
- Option #1: use the
BaseRequestOptions
class
You could extend this class and set the header to use for each request:
@Injectable()
export class DefaultRequestOptions extends BaseRequestOptions{
headers:Headers = new Headers({
'Content-Type': 'application/x-www-form-urlencoded'
});
}
And registers it as described below:
bootstrap(AppComponent,[
HTTP_PROVIDERS,
provide( RequestOptions, { useClass: DefaultRequestOptions })
});
- Option #2: extend the
Http
class itself
You could also extend the Http
class and set the headers you want in it, as described below:
@Injectable()
export class CustomHttp extends Http {
constructor(backend: ConnectionBackend, defaultOptions: RequestOptions) {
super(backend, defaultOptions);
}
request(url: string | Request, options?: RequestOptionsArgs): Observable<Response> {
return super.request(url, options);
}
get(url: string, options?: RequestOptionsArgs): Observable<Response> {
// Add headers into options
(...)
return super.get(url, options);
}
(...)
}
And registers it as described below:
bootstrap(AppComponent, [
HTTP_PROVIDERS,
provide(Http, {
useFactory: (backend: XHRBackend, defaultOptions: RequestOptions) => new CustomHttp(backend, defaultOptions),
deps: [XHRBackend, RequestOptions]
})
]);
Hope it helps you,
