SoapServer returns Internal Server Error (no log) in Laravel 5.2

[farhoudi]

I'm trying to run soap server in laravel 5.2. I create wsdl file using piotrooi/wsdl-creator and create SoapServer object then handle it.
And my SoapClient can call it but returns an Internal Server Error Without logging in error-log file.
Here is my code:

<?php namespace Giant\Http\Controllers;

class SoapController extends Controller {

    public function __construct() {
        parent::__construct();
        ini_set('soap.wsdl_cache_enabled', 0);
        ini_set('soap.wsdl_cache_ttl', 0);
        ini_set('default_socket_timeout', 300);
        ini_set('max_execution_time', 0);
    }

    public function server() {
        $location = url('server'); // http://payment.dev/server
        $namespace = $location;
        $class = "\\Giant\\Http\\Controllers\\HelloWorld";

        $wsdl = new \WSDL\WSDLCreator($class, $location);
        $wsdl->setNamespace($namespace);

        if (isset($_GET['wsdl'])) {
            $wsdl->renderWSDL();
            exit;
        }

        $wsdl->renderWSDLService();

        $wsdlUrl = url('wsdl/server.wsdl');
        $server = new \SoapServer(
            url('server?wsdl'),
            array(
                'exceptions' => 1,
                'trace' => 1,
            )
        );

        $server->setClass($class);
        $server->handle();
        exit;
    }

    public function client() {
        $wsdl = url('server?wsdl');
        $client = new \SoapClient($wsdl);

        try {
            $res = $client->hello('world');
            dd($res);
        } catch (\Exception $ex) {
            dd($ex);
        }
    }
}


class HelloWorld {
    /**
     * @WebMethod
     * @desc Hello Web-Service
     * @param string $name
     * @return string $helloMessage
     */
    public function hello($name) {
        return "hello {$name}";
    }
}

And my WSDL file: WSDL
And my routes:

Route::any('/server', 'SoapController@server');
Route::any('/client', 'SoapController@client');

There is no problem with wsdl-creator, It is working in laravel 4.2. And I have also tried nusoap and php2wsdl libraries.
My SoapClient is working well. Because it can get service from other soap servers in other urls, But SoapServer is not working well in Laravel 5.2. (I have tried my code in pure PHP script with namespaces and it is working)

The problem resolved.
I was wrong about log. I was checking error_log file for apache not the one for laravel.
And there i got TokenMismatchException and I just put my url of soap server inside except array of CsrfVerifyMiddleware.

Hi @AliFarhoudi :
Can you publish, the problem´s solution. I need resolve the error too.
Thanks.

[farhoudi]

Hi @devexsolutions
When you send a request (get/post/soap) to your controller (where your soap server is), laravel request handler tries to verify csrf token, and because your request is from another host laravel request handler does not allow your request to be processed.
To solve this issue you need to tell laravel not to verify csrf token for your soap server path. For example my soap server was running in /services route and I added this route to exceptions array so that laravel would not verify csrf token for this route.
Exceptions array is located in app/Http/MiddlewareVerifyCsrfToken.php file.
Whenever you encounter an internal server error there should a log for that default in storage/logs/laravel.log

[devexsolutions]

@AliFarhoudi dont fine work, Internal Error

My soap server run in /server route. This is my Middleware\VerifyCsrfToken code
`
**use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;

class VerifyCsrfToken extends BaseVerifier
{
/**
* The URIs that should be excluded from CSRF verification.
*
* @var array
/
protected $except = [
'/server'
];
}*
`
Routes.php
**
Route::any('/server', 'SoapController@server');

Try to remove preceding slash (replace '/server' with 'server').

[farhoudi]

One more thing. Your route method for soap server request needs to be defined as 'post' method.

Sorry @AliFarhoudi i beginner Laravel user

this my SoapController code

class SoapController extends Controller {

public function __construct() {
//    parent::__construct();
    ini_set('soap.wsdl_cache_enabled', 0);
    ini_set('soap.wsdl_cache_ttl', 0);
    ini_set('default_socket_timeout', 300);
    ini_set('max_execution_time', 0);
}

public function server() {
    $location = url('server'); // http://payment.dev/server
    $namespace = $location;
    $class = "\\MyProject\\Http\\Controllers\\HelloWorldController";

    $wsdl = new \WSDL\WSDLCreator($class, $location);
    $wsdl->setNamespace($namespace);

    if (isset($_GET['wsdl'])) {
        $wsdl->renderWSDL();
        exit;
    }

    $wsdl->renderWSDLService();

    $wsdlUrl = url('wsdl/server.wsdl');
    $server = new \SoapServer(
        url('server?wsdl'),
        array(
            'exceptions' => 1,
            'trace' => 1,
        )
    );

    $server->setClass($class);
    $server->handle();
    exit;
}

public function client() {
    $wsdl = url('server?wsdl');
    $client = new \SoapClient($wsdl);

    try {
        $res = $client->hello('world');
        dd($res);
    } catch (\Exception $ex) {
        dd($ex);
    }
}

Routes.php

Route::any('/client', 'SoapController@client');
Route::any('/server', 'SoapController@server');
Route::post('/server', function()
{
//
});

@AliFarhoudi I solved the problem.
The bug, is a file call Class extended from VerifyCsrfToken.php. I called directly VerifyCsrfToken in Kernel.php

Not show the variable name!!!

Thanks.

Hi:
My client method not correctly read the wsdl file

public function client() {
$wsdl = url('server?wsdl');

    $client = new \SoapClient($wsdl);
    dd($client);
    try {
        $res = $client->hello('world');
        dd($res);
    } catch (\Exception $ex) {
        dd($ex);
    }
}

I used dd($client) for trace and show this:

SoapClient {#166 ▼
+"_soap_version": 1
+"sdl": Unknown resource @199
}

Can you help me?

Thanks.
