Ionic/angular - Login: POST to HTML

I’m new with Ionic and I’m in big doubt.
I have a website login like this:

<form method='POST' action=''>

<input type='text' name='login''></input>

<input type='password' name='pass'></input>

<input type='submit'>Login</input>


I am making an app in ionic / angular and I want to do this same login, I’ve seen several tutorials and ways to pass a POST, but I can not do, could someone help me?

ps: Sorry my english, I’m not fluent

A form with no explicit enctype implies a content type of x-www-form-urlencoded. Using a URLSearchParams as the body indicates to Angular’s HttpClient to use that content type:

let body = new URLSearchParams();
body.set("login", login);
body.set("password", password);"url", body);

Currently my code looks like this

<ion-content ion-padding>
  <form (ngSubmit)="logForm()">
      <ion-label position="floating">
        <ion-icon name="mail" item-start></ion-icon>
      <ion-input color="secondary" type="text" [(ngModel)]="login" name="email" ></ion-input>
      <ion-label position="floating">
          <ion-icon name="lock" item-start></ion-icon>
      <ion-input color="secondary" type="password" [(ngModel)]="pass" name="pass"></ion-input>


  <ion-button icon-left size="medium" color="success" type="submit" shape="round" expand="full" (click)="makeLogin()" tappable>
    <ion-icon name="log-in"></ion-icon>

How should makeLogin () function, to perform the action ?
