Code example of soapServer supporting wsdl under laravel framework

本篇文章给大家带来的内容是关于laravel中soapServer支持wsdl的代码示例，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。

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

上边这段代码是无wsdl模式下的，但是这次是对接第三方的服务，需要我们这边去定义soap webservice，第三方来调用，第三方定义的是wsdl模式的，所以今天研究了下。

laravel代码示例（其它框架类似思考方式）：

• 主要逻辑代码 - SoapService.php

<?php
/**
 * soap服务端
 */

namespace App\Services;

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

• 创建路由

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

• 路由主要实现方法-wsdl不存在则创建，不需要手动创建，url：https:xxx/soapurl?wsdl

<?php

Class SoapCallbackController {
    public function soapFun()
        {
            try {
                $procClass     = &#39;App\Services\SoapService&#39;;
                $classNameFull = explode(&#39;\\&#39;, $procClass);
                $className     = array_pop($classNameFull);
                $storagePath   = storage_path();
                if (! file_exists($storagePath . &#39;/wsdl/&#39; . $className . &#39;.wsdl&#39;)) {
                    if (! file_exists($storagePath . &#39;/wsdl/&#39;)) {
                        mkdir($storagePath . &#39;/wsdl/&#39;, 0777, true);
                    }
                    require_once app_path() . &#39;/Libs/SoapDiscovery.php&#39;;
       
                    $soapDiscovery = new \SoapDiscovery($procClass, &#39;soap&#39;);
                    $file          = fopen($storagePath . &#39;/wsdl/&#39; . $className . &#39;.wsdl&#39;, &#39;w&#39;);
                    fwrite($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服务创建异常');
            }
        }
    }

$soap = new SoapClient(&#39;https:xxx/soapurl?wsdl&#39;);
// 以下两种调用方式
