yii2实现WebService 使用 SoapDiscovery

结合SoapDiscovery实现简单的WebService服务

1 修改php.ini文件

　　php_soap.dll

　　extension=php_soap.dll

2 WebService 实现主要步骤

• 生成wsdl描述文件
• 使用SoapServer注册服务
• 使用SoapClient调用服务

3 目录结构以及代码　

根目录

　　==service目录

　　||== SoapDiscovery.php 【Soap wsdl文件生成类 】

　　||==SoapService.php 【web service 提供的列表】

　　==controllers目录

　　||==CreatewsController.php 【生成WSDL文件 】

　　||==ServiceController【注册、调用测试】

SoapService.php 【web service 提供的列表】

<?php
/**
 * Created by PhpStorm.
 * User: 知电
 * Date: 2018-1-2

 */

{

    }

    public function SayHello($name){

    }
}

CreatewsController.php 【生成WSDL文件 】

<?php

namespace app\controllers;

use Yii;
use yii\web\Controller;
use app\service\SoapService;
use app\service\SoapDiscovery;

class CreatewsController extends Controller
{
    public function actionIndex()
    {
        $disco = new SoapDiscovery('\app\service\SoapService', 'soap'); //第一个参数是类名（生成的wsdl文件就是以它来命名的），即Service类，第二个参数是服务的名字（这个可以随便写）。
        $r = $disco->getWSDL();
    }
}

ServiceController.php【注册、调用测试】

<?php
/**
 * Created by PhpStorm.
 * User: 知电
 * Date: 2018-1-2
 * Time: 10:16
 */
namespace app\controllers;
use Yii;
use yii\web\Controller;
class ServiceController extends Controller
{
    public $ws_url = 'http://host.com/service/ws?wsdl'; //服务注册地址
    public function init()
    {
        Yii::$app->getRequest()->enableCsrfValidation = false;
    }

    /**
     * 服务地址注册  ／service/ws
     */
    public function actionWs()
    {
        //设置Yii响应格式为XML
        \Yii::$app->response->format = \yii\web\Response::FORMAT_XML;
        $server = new \SoapServer(dirname(dirname(__FILE__)) . '/\service\app\service\SoapService.wsdl', array('soap_version' => SOAP_1_2));
        $server->setClass('\app\service\SoapService'); //注册Service类的所有方法
        $server->handle(); //处理请求
    }

    /**
     * 测试调用
     */
    public function actionTest()
    {
        $client = new \SoapClient($this->ws_url, array(
            'soap_version'   => SOAP_1_2,
            'cache_wsdl' => WSDL_CACHE_NONE
        ));
        echo 'SOAP 类型';
        echo '<pre>';
        var_dump($client->__getTypes());//获取服务器上数据类型
        echo ('</pre>');
        echo 'SOAP 方法';
        echo '<pre>';
        var_dump($client->__getFunctions());//获取服务器上提供的方法
        echo ('</pre>');
        echo ("执行的结果:");
        $result = $client->__soapCall('SayHello',[111]);
        var_dump($result);
    }
}

备注：生成WSDL文件后，需把WSDL里面的 address location更改一下变为实际的注册地址[参考ServiceController.php说明]。
