使用wp-rest api登录wordpress网站

Question

I'm using Wordpress 4.8 and i am new to rest api . I have 2 websites , one is www.example.com and second is www.example.com/site2 . That is second website is installed inside the first .

In example.com I have many users. In site 2 , i have a custom page & in that page i create a custom forms for login . The form is checking the details based on first website users . That is some one enter the login details of first website then they can able to login . Please check my form

<form>
<input type="text" name="user_name" class="user_name" required>
<input type="password" name="user_password" class="user_password" required>
<input tuype="submit" name="submit" class="submit">
</form>

<script>

     $(".submit").on("click",function(){
           var username = $(".user_name").val();
           var password = $(".user_password").val();
            });

</script>

Please help to complete this form .Should i need to use curl ? How can i check the login details with the help of rest api

Edit

From my further investigation i am able to do this much code

   $(".submit").on("click",function(){
       var username = $(".user_name").val();
       var password = $(".user_password").val();
       var posting = $.post( 'ajax.php', { user1: username, pass1:password } );
           posting.done(function( data ) {
             MYCODE 

             });
    });

In ajax.php I write

 ini_set('display_errors', 0);
    error_reporting(E_ALL);

$username = $_POST["user1"];
$password = $_POST["pass1"];
$headers = array();
//$headers[] = 'Accept: application/json';
$headers[] = 'Content-Type: application/json';

$curl = curl_init();

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_URL,"http://www.example.com/wp-json/");
curl_setopt($curl, CURLOPT_HEADER ,0);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, array('username'=>$username, 'password'=>$password));
$resp = curl_exec($curl);

curl_close($curl);

echo $resp;

Still no luck.
