Pass JSON value from PHP to Angular through URL - php

Question

I'm having trouble sending JSON object back to Angular application from PHP script. I tried to do it by URL but I am unable to send JSON:
header("Location: http://localhost:8000/index.html#/AnotherPage/abcd");
Here is my PHP code
<?php
header("Pragma: no-cache");
header("Cache-Control: no-cache");
header("Expires: 0");
// following files need to be included
require_once("./lib/config_paytm.php");
require_once("./lib/encdec_paytm.php");
$paytmChecksum = "";
$parameterList1;
$paramList = array();
$isValidChecksum = "FALSE";
$parameterList1 = $_POST;
$paramList = $_POST;
$paytmChecksum = isset($_POST["CHECKSUMHASH"]) ? $_POST["CHECKSUMHASH"] : ""; //Sent by Paytm pg
//Verify all parameters received from Paytm pg to your application. Like MID received from paytm pg is same as your application’s MID, TXN_AMOUNT and ORDER_ID are same as what was sent by you to Paytm PG for initiating transaction etc.
$isValidChecksum = verifychecksum_e($paramList, PAYTM_MERCHANT_KEY, $paytmChecksum); //will return TRUE or FALSE string.
if($isValidChecksum == "TRUE") {
echo "<b>Checksum matched and following are the transaction details:</b>" . "<br/>";
if ($_POST["STATUS"] == "TXN_SUCCESS") {
echo "<b>Transaction status is success</b>" . "<br/>";
print_r($paramList);
echo $paramList;
//Process your transaction here as success transaction.
//Verify amount & order id received from Payment gateway with your application's order id and amount.
}
else {
echo "<b>Transaction status is failure</b>" . "<br/>";
}
if (isset($_POST) && count($_POST)>0 )
{
foreach($_POST as $paramName => $paramValue) {
echo "<br/>" . $paramName . " = " . $paramValue;
}
print_r($paramList);
}
}
else {
echo "<b>Checksum mismatched.</b>";
//Process transaction as suspicious.
}
header("Location: http://localhost:8000/index.html#/AnotherPage/abcd");
?>
here is my Angular project typescript code , which will receive json data sent by php ,
#Component({
selector: 'page-another',
templateUrl: 'another.html',
})
export class AnotherPage {
userData:any;
id:any;''
constructor(public navCtrl: NavController, public navParams: NavParams) {
this.userData = navParams.get('data');
// this.id = navParams.get('id');
console.log(navParams.get('id'));
console.log(this.userData);
}
}
