import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { HttpModule, Http, JsonpModule} from '@angular/http';
import { Observable} from 'rxjs'; 
import 'rxjs/add/operator/map';


@NgModule({

    imports: [     
          BrowserModule,
          HttpModule,
          JsonpModule,

        ]

  }) 

  @Injectable({
    providedIn:'root'
  })
 export class GithubService{
       constructor(private http:Http){

       }

       getUser(){
         const searchText ="js";
         const url = "http://api.github.com/search/users?q="+searchText;  
         this.http.get(url).subscribe(
           res=> {
             const data=res.json();
             console.log(data);
             return data;
           }
         )
       }
   }

  StaticInjectorError(Platform: core)[GithubService -> Http]: 
    NullInjectorError: No provider for Http!

Please follow below 2 steps,

Go to app.moudle.ts

  1. Add javascript import 

    import { HttpModule, Http, JsonpModule} from '@angular/http';

Update: Angular v6+
From older versions (Angular v2 - v5): HttpModule is now deprecated and you need to replace it with HttpClientModule or else you will get the error too.

In your app.module.ts file change these

  1. import { HttpClientModule} from "@angular/common/http";

  2. Then update the modules imports[ ] array HttpClientModule

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