The Http Interceptor is an interface and used to
implement the intercept method.
Example
-
//Register an Interceptor
(HTTP_INTERCEPTORS) in the app Module.
import
{NgModule} from
'@angular/core';
import
{HTTP_INTERCEPTORS}
from '@angular/common/http';
@NgModule({
providers: [{
provide: HTTP_INTERCEPTORS,
useClass: MyInterceptor,
multi: true,
}],
})
export
class AppModule
{}
And
//The HttpInterceptor is an interface
and used to implement the intercept method.
import
{Injectable} from
'@angular/core';
import
{HttpEvent, HttpInterceptor,
HttpHandler, HttpRequest}
from '@angular/common/http';
@Injectable()
export
class MyInterceptor
implements HttpInterceptor
{
intercept(req:
HttpRequest<any>,
next: HttpHandler):
Observable<HttpEvent<any>>
{
const reqHeader
= req.clone({headers:
req.headers.set('Authorization',
'MyAuthToken')});
return next.handle(reqHeader);
}
}
