detectContentType(): ContentType
detectContentTypeFromBody(): ContentType

Description
The Request's interface is inspired by the Request constructor defined in the Fetch Spec, but is considered a static value whose body can be accessed many times. There are other differences in the implementation, but this is the most significant.
Request instances are typically created by higher-level classes, like Http and
Jsonp, but it may occasionally be useful to explicitly create Request instances.
One such example is when creating services that wrap higher-level services, like Http,
where it may be useful to generate a Request with arbitrary headers and search params.
import {Injectable, Injector} from '@angular/core';
import {HTTP_PROVIDERS, Http, Request, RequestMethod} from '@angular/http';
@Injectable()
class AutoAuthenticator {
constructor(public http:Http) {}
request(url:string) {
return this.http.request(new Request({
method: RequestMethod.Get,
url: url,
search: 'password=123'
}));
}
}
var injector = Injector.resolveAndCreate([HTTP_PROVIDERS, AutoAuthenticator]);
var authenticator = injector.get(AutoAuthenticator);
authenticator.request('people.json').subscribe(res => {
//URL should have included '?password=123'
console.log('people', res.json());
});
