php - 带有 symfony 的 SOAP 网络服务

Question

我用 symfony2 编写了一个 Web 服务，位于 tutorial 中.

我的路线是:

_soap:
path:      /soap
defaults:  { _controller: AcmeSoapBundle:Default:index}

我的配置:

services:
hello_service:
    class: Acme\SoapBundle\Services\HelloService
    arguments: ["@mailer"]

我的服务:

namespace Acme\SoapBundle\Services;

class HelloService
{
    private $mailer;

    public function __construct(\Swift_Mailer $mailer)
    {
        $this->mailer = $mailer;
    }

    public function hello($name)
    {

        $message = \Swift_Message::newInstance()
            ->setTo('<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fa979fba9f829b978a969fd4999597" rel="noreferrer noopener nofollow">[email protected]</a>')
            ->setSubject('Hello Service')
            ->setBody($name . ' says hi!');

        $this->mailer->send($message);

        return 'Hello, '.$name;
    }
}

我的 Controller :

namespace Acme\SoapBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;

class DefaultController extends Controller
{
    public function indexAction()
    {
        $server = new \SoapServer('hello.wsdl');
        $server->setObject($this->get('hello_service'));

        $response = new Response();
        $response->headers->set('Content-Type', 'text/xml; charset=ISO-8859-1');

        ob_start();
        $server->handle();
        $response->setContent(ob_get_clean());

        return $response;
    }
}

hello.wsdl ( web/hello.wsdl )

    <?xml version="1.0" encoding="ISO-8859-1"?>

            <output message="tns:helloResponse"/>
        </operation>
    </portType>

    <binding name="hellowsdlBinding" type="tns:hellowsdlPortType">

        <operation name="hello">
            <soap:operation soapAction="urn:arnleadservicewsdl#hello" style="rpc"/>

            <input>
                <soap:body use="encoded" namespace="urn:hellowsdl"
                    encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
            </input>

            <output>
                <soap:body use="encoded" namespace="urn:hellowsdl"
                    encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
            </output>
        </operation>
    </binding>

    <service name="hellowsdl">
        <port name="hellowsdlPort" binding="tns:hellowsdlBinding">
            <soap:address location="http://example.com/app.php/soap" />
        </port>
    </service>
</definitions>

但我看到以下错误:

XML Parsing Error: no element found
Location: http://xxx.xxxx.xxx/unproject/web/app_dev.php/soap
Line Number 1, Column 1:

如何解决这个问题？ 感谢您的帮助

我认为您已经从该链接复制了 wsdl 文件的内容，但错过了更改 location部分，您应该更改 <soap:address location="http://example.com/app.php/soap" />到您自己的 URL，例如 http://xxx.xxxx.xxx/unproject/web/app_dev.php/soap ..
