Angular 6 :

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

@Injectable()
export class GetData {
    constructor( private http: HttpClient ) { }
    post( ) {
      data = [ {username : 'test',password : '1234' }];
      return this.http.post('login.php' , data );

Try this:

import {Injectable} from '@angular/core';
import { HttpClient,HttpParams  } from '@angular/common/http';

@Injectable()
export class GetData {
    constructor( private http: HttpClient ) { }
    post( ) {
     let data= new HttpParams()
    .append("username", "test")
    .append("password", "1234")


      return this.http.post('login.php' , data );
    }
}
