Yii 2 结合 SoapDiscovery，实现 Soap WebService 服务 [ 1.0 版本 ]
Yii2结合SoapDiscovery， 实现Soap WebService服务
SOAP Web Service 一般PHPER们不会遇到，一旦有这个需求，写Wsdl描述文件，尤其是给C#之类的调用方，还是很伤脑筋的。
大家都知道把大象装冰箱，统共分几步，其实实现PHP SOAP也就三步：
- 生成wsdl描述文件
- 使用SoapServer注册服务
- 使用SoapClient调用服务
所以，本人就以Yii2框架为例，一步步实现实现web service, 仅供参考。
Soap wsdl文件生成类 app\service\SoapDiscovery.php
注意， SoapDiscovery类来源于网络，本文中有所改动，结合yii2, 加入了namesapce, 特此声明。

web service 类 app\service\SoapService.php
namespace app\service;
class SoapService
{
public function HelloWorld() {
return "Hello";
}
public function Add($a, $b) {
return $a + $b;
}
}
控制器
- 生成wsdl app\controllers\CreatewsController.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();
}
}
- 注册web service app\controllers\ServiceController.php
<?php
namespace app\controllers;
use Yii;
use yii\web\Controller;
use app\service\SoapService;
class ServiceController extends Controller
{
public $ws_url = 'http://host.com/service/ws?wsdl';
public function init()
{
Yii::$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(__FILE__) . '/\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 '<pre>';
echo 'SOAP types';
print_r($client->__getTypes());
echo 'SOAP Functions';
print_r($client->__getFunctions());
$result = $client->__soapCall('Add', [1, 2]);
var_dump($result);
}
}
Websercie & Rest 测试软件
- SoapUI 大杀器
- Chrome插件 - Boomerang 轻量级，相当够用了。
参考资料&常见问题
- The SoapServer class
- The SoapClient class
- 调用.NET SOAP，传参
- PHP Soap Error - Procedure 'xxx' not present
- 缓存问题， 设置 'cache_wsdl' => WSDL_CACHE_NONE
觉得很赞

您好，请问生成的wsdl文件，使用soapui测试，报错。是还需要配置啥东西嘛
