.NET 解决方案的 nusoap WebService 错误

Question

我用 nuSOAP WebService 制作了一个 Laravel，它在除 .NET 解决方案之外的所有环境中都能正常工作......

#PHP /app/Http/route.php

$app->group(['prefix' => 'test', 'namespace' => 'App\Http\Controllers'], function () use ($app) {

    $app->get('/', 'TestController@index');
    $app->get('/{any}', 'TestController@index');
    $app->post('/', 'TestController@index');
    $app->post('/{any}', 'TestController@index');

});

# PHP /app/Http/Controllers/TestController.php

<?php namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Common;
use SoapBox\Formatter\Formatter;

class TestController extends Controller
{
    public function __construct()
    {
        $this->server = new \soap_server;
        $end_point = env('END_POINT') . '/test/wsdl';
        $this->server->configureWSDL('test', 'urn:test', $end_point, 'rpc');

        $this->server->register(
            'testMethod',
            [
                'one' => 'xsd:string',
                'two' => 'xsd:string',
            ],
            [
                'return' => 'xsd:array'
            ],
            'urn:testWSDL',
            'urn:testWSDL#testMethod',
            'rpc',
            'encoded',
            'Test Method'
        );
    }

    function index(Request $request, $data = NULL)
    {
        $_SERVER['QUERY_STRING'] = '';
        if ( $request->segment(2) == 'wsdl' ) $_SERVER['QUERY_STRING'] = 'wsdl';
        return $this->server->service(file_get_contents('php://input'));
    }
}

# PHP /app/Http/helpers.php

<?php use SoapBox\Formatter\Formatter;

function arrayToXml($array, $remove_structure = TRUE) {

    $array = Formatter::make($array, Formatter::ARR);

    $ret = $array->toXml();

    if ( $remove_structure )
    {
        $ret = str_replace('<?xml version="1.0" encoding="utf-8"?>', '', $ret);
        $ret = str_replace('<xml>', '', $ret);
        $ret = str_replace('</xml>', '', $ret);
    }

    return trim($ret);
}

function testMethod($one, $two)
{
    return arrayToXml([
        "one"   =>  $one,
        "two"   =>  $two
    ]);
}

如果我尝试使用 SoapGUI，我会发送：

<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:testWSDL">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:testMethod soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
         <one xsi:type="xsd:string">first</one>
         <two xsi:type="xsd:string">second</two>
      </urn:testMethod>
   </soapenv:Body>
</soapenv:Envelope>

我收到了……

<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
   <SOAP-ENV:Body>
      <ns1:testMethodResponse xmlns:ns1="urn:testWSDL">
         <return xsi:type="xsd:array">
            <one>first</one>
            <two>second</two>
         </return>
      </ns1:testMethodResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

原始响应是：

我也在soapclient.com/soaptest.html 中尝试过并且工作得很好...... 但在 .NET 解决方案中......我将其添加为 Web 参考：

然后添加下一个代码......我得到了智能感知......

然后单击 Click Me 按钮并出现此错误：

System.Xml.dll 中发生了“System.InvalidOperationException”类型的第一次机会异常 System.InvalidOperationException：错误 en el documento XML (1, 479)。 ---> System.InvalidCastException: No se puede asignar el objeto de tipo System.Xml.XmlNode[] al objeto de Tipo System.String。 zh Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReadertest.Read2_testMethodResponse() zh Microsoft.Xml.Serialization.GeneratedAssembly.ArrayOfObjectSerializer3.Deserialize（XmlSerializationReader 阅读器） zh System.Xml.Serialization.XmlSerializer.Deserialize（XmlReader xmlReader，字符串 encodingStyle，XmlDeserializationEvents 事件） --- Fin del seguimiento de la pila de la excepción interna --- zh System.Xml.Serialization.XmlSerializer.Deserialize（XmlReader xmlReader，字符串 encodingStyle，XmlDeserializationEvents 事件） zh System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle) en System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage 消息，WebResponse 响应，流 responseStream，布尔 asyncCall) zh System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] 参数) 在 testingSolution.local31.test.testMethod（字符串一，字符串二） C:\Documents and Settings\admin\Mis documentos\testingSolution\Web References\local31\Reference.vb:línea 80 en testingSolution.Testeos.Button3_Click(Object sender, EventArgs e) en C:\Documents and Settings\admin\Mis documentos\testingSolution\index.vb:linea 50

如果我将返回类型更改为字符串...在 .NET 解决方案中，我得到：

但在 SoapGUI（以及所有其他应用程序）中：

<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
   <SOAP-ENV:Body>

         <return xsi:type="xsd:string">&lt;one>mundo&lt;/one>&lt;two>aunque&lt;/two></return>
      </ns1:testMethodResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我能做些什么来解决这个问题？因为我需要返回一个数组。谢谢！

Answer 1

最后还是这样：

//  whether $methodreturn is a string of literal XML
$this->server->methodreturnisliteralxml = true;
