Error: Router service provider not found in Angular 2 RC5!

Having trouble with using this.router.navigate.

Here is the content of my app.module.ts file:

    import {NgModule, NgModuleMetadataType}      from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import {FormsModule}    from '@angular/forms';
    import { HttpModule } from '@angular/http';
    ...
    import {routing} from "./app.routing";
    import {entry} from "./entry.component";
imports: [ 
        BrowserModule,
        FormsModule,
        routing,
        HttpModule,
    ],

Next is the Test component:

import { Component } from '@angular/core';
import {HttpClient} from "./HttpClient.component";
import {Router} from "@angular/router-deprecated";

@Component({
    templateUrl: 'templates/entry.html'
})
export class entry {
    ...
    constructor(head:HeaderComponent, private httpClient: HttpClient, private router: Router) {
        this.httpClient = httpClient;
    }
    nav_test(){
        this.router.navigate(['search']);
    }
}

Followed by the app.routing content:

import { Routes, RouterModule } from '@angular/router';
const appRoutes: Routes = [
    {
        path: '',
        redirectTo: '/home',
        pathMatch: 'full',
    },
    {
        path: 'home',
        component: HomeComponent
    },
    {
        path: 'search',
        component: SearchComponent

    }

];
export const routing = RouterModule.forRoot(appRoutes, {useHash: true});

At the end, I am encountering this error:

EXCEPTION: Error: Uncaught (in promise): EXCEPTION: Error in ./entry class entry_Host - inline template:0:0 ORIGINAL EXCEPTION: No provider for Router!

Thank you for your help!

Answer №1

The problem lies in how you are importing your test component,

Instead of using

import {Router} from "@angular/router-deprecated";

You should be using,

import { Router } from '@angular/router';

I hope this solution resolves the issue for you!

Answer №2

Uncertain about how the useHash: true feature functions, but I am specifying the location strategy in @NgModule:

providers:[{provide: LocationStrategy, useClass: HashLocationStrategy}]

Additionally, I am utilizing the most up-to-date router, rather than the outdated version.
