在Laravel中的支付网关回叫时，会话自动销毁

我正在尝试将CCvenue.com支付网关集成到我的Laravel 7项目中。我面临的唯一问题是在回拨URL中，在从支付网关获得帖子数据后，活动会话自动销毁。我还向中间件添加了CSRF异常。

PayController(生成付款请求和URL)

<?php

namespace AppHttpControllersuser;

use AppHttpControllersController;
use IlluminateHttpRequest;

class PayController extends Controller

{

public function __construct()
{
    $this->middleware('auth:web');
}


public function index()
{

    return view('user.addmoney');
}


public function addmoney(Request $request)
{
    $validatedData = $request->validate([
        'Amount' => 'required|numeric',
    ]);

    $Amount = $validatedData['Amount'];

    $working_key = '5dfsdfsdf3323423'; //Shared by CCAVENUES
    $access_code = 'asdasdas234234'; //Shared by CCAVENUES

    echo $merchant_data = 'merchant_id=555&order_id=123654789&amount=' . $Amount . '&currency=AED&redirect_url=http://localhost:8000/addmoneyresponse&cancel_url=http://localhost:8000/addmoneyresponse&language=EN&billing_name=Charli&billing_address=Room no 1101, near Railway station Ambad&billing_city=Indore&billing_country=India&billing_tel=9595226054&billing_email=atul.kadam@avenues.info&promo_code=&customer_identifier=&integration_type=iframe_normal&';
    $encrypted_data =  $this->encrypt($merchant_data, $working_key); // Method for encrypting the data.


    echo "<br>";

    $production_url = 'https://secure.ccavenue.ae/transaction/transaction.do?command=initiateTransaction&encRequest=' . $encrypted_data . '&access_code=' . $access_code;

    return redirect()->away($production_url);


    //return view('user.addmoneyrequest', compact('production_url'));


}






function encrypt($plainText, $key)
{
    $key = $this->hextobin(md5($key));
    $initVector = pack("C*", 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f);
    $openMode = openssl_encrypt($plainText, 'AES-128-CBC', $key, OPENSSL_RAW_DATA, $initVector);
    $encryptedText = bin2hex($openMode);
    return $encryptedText;
}

function decrypt($encryptedText, $key)
{
    $key = $this->hextobin(md5($key));
    $initVector = pack("C*", 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f);
    $encryptedText = $this->hextobin($encryptedText);
    $decryptedText = openssl_decrypt($encryptedText, 'AES-128-CBC', $key, OPENSSL_RAW_DATA, $initVector);
    return $decryptedText;
}
//*********** Padding Function *********************

function pkcs5_pad($plainText, $blockSize)
{
    $pad = $blockSize - (strlen($plainText) % $blockSize);
    return $plainText . str_repeat(chr($pad), $pad);
}

//********** Hexadecimal to Binary function for php 4.0 version ********

function hextobin($hexString)
{
    $length = strlen($hexString);
    $binString = "";
    $count = 0;
    while ($count < $length) {
        $subString = substr($hexString, $count, 2);
        $packedString = pack("H*", $subString);
        if ($count == 0) {
            $binString = $packedString;
        } else {
            $binString .= $packedString;
        }

        $count += 2;
    }
    return $binString;
    }
}

PayResponseController(进程回调)

<?php

namespace AppHttpControllersuser;

use AppHttpControllersController;
use IlluminateHttpRequest;


class PayResponseController extends Controller
{


    public function addmoneyresponse(Request $request)
    {


        return $request->all();

        //return view('user.dashboard');



    }
}

api

我遇到了这个问题，我添加了一个推荐答案回调路由并在其中返回一个视图：

在routes文件夹中，api.php文件：

Route::post('/callback','callbackController@callback');

内部controller：

public function callback(Request $request) {

// some code here 

return view('callback');
}

并将此设置为回调：

http://yourdomain.com/api/callback
