Angular2 typescript POST request
<p>I'm testing this sample: <a href="http://plnkr.co/edit/WTu5G9db3p4pKzs0WvW6?p=preview" rel="nofollow">http://plnkr.co/edit/WTu5G9db3p4pKzs0WvW6?p=preview</a>. </p>

<p>This code, implements a login form with name, mail, profile. On clicking submit button, an alert appears on display with name and email fields.</p>

<pre><code>saveUser() {
    if (this.userForm.dirty &amp;&amp; this.userForm.valid) {
        alert(`Name: ${this.userForm.value.name} Email: ${this.userForm.value.email}`);
    }
}
</code></pre>

<p>On above, the saveUser function in <code>app.component.ts</code>. It executes the alert on clicking button. On saveUser function, I would like to invoke a POST request. How can I do it? </p>
