resolved:

$server = new \SoapServer(null, ['uri' => 'noganluonguri']);
$server->setObject(new NganluongServer());
ob_start();
$server->handle();
return ob_get_clean();

the above code is in non-wsdl mode, but this time it is to interface with third-party services, so we need to define the soap webservice, third-party to call it. The third party defines wsdl mode, so we studied it today.

laravel code example (other frameworks think similarly):

1. main logic code-SoapService.php

<?php
/**
 * soap
 */

namespace App\Services;

Class SoapService
{
    public function UpdateOrder($param1, $param2)
    { 
        return $param1 + $param2;
    }
}

1. create a route

$api->any('soapUrl', 'SoapCallbackController@soapFun');

1. the main implementation method of routing-if wsdl does not exist, it does not need to be created manually. Url: https:xxx/soapurl?wsdl

Class SoapCallbackController {
    public function soapFun()
        {
            try {
                $procClass     = 'App\Services\SoapService';
                $classNameFull = explode('\\', $procClass);
                $className     = array_pop($classNameFull);
                $storagePath   = storage_path();
                if (! file_exists($storagePath . '/wsdl/' . $className . '.wsdl')) {
                    if (! file_exists($storagePath . '/wsdl/')) {
                        mkdir($storagePath . '/wsdl/', 0777, true);
                    }
                    require_once app_path() . '/Libs/SoapDiscovery.php';
       
                    $soapDiscovery = new \SoapDiscovery($procClass, 'soap');
                    $file          = fopen($storagePath . '/wsdl/' . $className . '.wsdl', 'w');
                    fwrite($file, $soapDiscovery->getWSDL());
                    fclose($file);
                }
                $server = new \SoapServer($storagePath . '/wsdl/' . $className . '.wsdl', array('soap_version' => SOAP_1_2));
                $server->setClass($procClass);
                $server->handle();
            } catch (\Exception $e) {
                Log::error('wsdl');
            }
        }
    }

1. generate the wsdl class-SoapDiscovery.php
