SOAP-ERROR：解析WSDL：无法从'http://127.0.0.1/test/index?wsdl'加载：

Posted 2021-04-14

当我在zend framework 2.0中使用SOAP组件时遇到问题

以下是代码：

namespace UserController;

use ZendMvcControllerAbstractActionController;
use ZendSoapServer;
use ZendSoapClient;
use ZendSoapAutoDiscover;
use UserModelMyTest;

class TestController extends AbstractActionController {
private $_WSDL_URI = "http://127.0.0.1/test/index?wsdl";

private function handleWSDL() {
    $autodiscover = new AutoDiscover(); 
    //ini_set("soap.wsdl_cache_enabled", 0);
    $autodiscover->setClass('UserModelMyTest')
                 ->setUri($this->_WSDL_URI);
    $wsdl = $autodiscover->generate();
    header("Content-type: text/xml");
    echo $wsdl->toXml();
    exit;   
}

private function handleSOAP() {
    $soap = new Server($this->_WSDL_URI,array('encoding' => 'utf-8','soap_version'=>SOAP_1_2));
    $soap->setClass('UserModelMyTest');
    $soap->handle();
    exit;
}

public function indexAction(){
    if(isset($_GET['wsdl'])) {
        $this->handleWSDL();
    } else {
        $this->handleSOAP();
    }
}

public function clientAction(){
    $client = new Client('http://127.0.0.1/test/index?wsdl');
    $result = $client->getUser(31);
    var_dump($result);exit;
}

}

当我访问http://localhost/test/index?wsdl时，它返回WSDL。

但是当我访问http://localhost/test/index时，它返回错误：

SOAP-ERROR：解析WSDL：无法从http://127.0.0.1/test/index?wsdl加载：无法加载外部实体"http://127.0.0.1/test/index?wsdl"

当我访问http://localhost/test/client时，它返回

 #1 E:WWWmoduleUsersrcUserControllerTestController.php(44): ZendSoapClient->__call('getUser', Array)

这是MyTest.php文件

namespace UserModel;

class MyTest{
/**
 * To get the register information of the user
 * 
 * @return string
 */
public function getUser(){
    return 'hello';
}
}

提前致谢。

答案

要创建Soap服务器，您只需要WSDL文件，而不是用于将其提供给其他客户端的URL。实际上，最好不要使用URL来执行此操作，因为对Soap服务器的每个请求都将启动子请求以获取WSDL。

尝试在创建WSDL后将其放在某处，并在后续请求中从那里获取它。在没有指定接口的情况下进行开发时，每次自动检测它都是很好的。一旦其他人使用这个界面并依赖其稳定性，这将破坏事情。
