Angular EXCEPTION: No provider for Http

Solution 1:

Import the HttpModule

import { HttpModule } from '@angular/http';

@NgModule({
    imports: [ BrowserModule, HttpModule ],
    providers: [],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})
export default class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

Ideally, you split up this code in two separate files. For further information read:

• https://v2.angular.io/docs/ts/latest/cookbook/rc4-to-rc5.html
• https://v2.angular.io/docs/ts/latest/guide/ngmodule.html

Solution 2:

>= Angular 4.3

for the introduced HttpClientModule

import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    BrowserModule,
    FormsModule, // if used
    HttpClientModule,
    JsonpModule // if used
  ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Angular2 >= RC.5

Import HttpModule to the module where you use it (here for example the AppModule:

import { HttpModule } from '@angular/http';

@NgModule({
  imports: [
    BrowserModule,
    FormsModule, // if used
    HttpModule,
    JsonpModule // if used
  ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Importing the HttpModule is quite similar to adding HTTP_PROVIDERS in previous version.
