如何从Ajax或Json中抓取数据

I want to scrapped data from this url

I am able to fetch simple data from html tags usign curl but not able to fetch data from Json or Ajax, I am not sure is it Ajax or Json data.

In below screen shot I want to fetch Appliance Models Data.

Which is coming form I think json or ajax. ==>>

Here below is my script to get data from page -

$loginURL = "https://www.apwagner.com/appliance-part/wpl/wp661600";
//$file='source.html'; //create a html file to save source code
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch, CURLOPT_URL, $loginURL);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $data = curl_exec($ch);
    curl_close($ch);

Please provide some guidance to fetch this info ..

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"https://www.apwagner.com/Product/GetPartModel");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
            "partNumber=wp661600&make=wpl");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);

curl_close ($ch);

The part of data page gets through ajax request.

see this screenshot

You need to do it with curl after your first curl response is received

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"https://www.apwagner.com/Product/GetPartModel");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
            "partNumber=wp661600&make=wpl");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec ($ch);

curl_close ($ch);

Or try to scrap data using python script

import string
import time
from selenium import webdriver

driver = webdriver.Chrome('<path to your chrome driver>') 
driver.get('https://www.apwagner.com/appliance-part/wpl/wp661600');
