PHP SOAP 返回 SOAP 错误：服务器无法使用 .asmx Web 服务处理请求

Question

我很难让 SOAP 请求正常工作，这需要 XML 字符串作为输入。

它抛出

“SOAP 错误：服务器无法处理请求。 ---> 值不能为空。参数名称：s”

无论我发送什么输入，我都使用了 nusoap 但无济于事, PHP 肥皂库。 我使用的代码是：

<?
$aOptions = array(
'location' => 'http://webserviceurl.asmx',
'uri' => 'http://tempuri.org/',
"style" => SOAP_RPC,
"use" => SOAP_ENCODED
);
$client = new SOAPClient(null, $aOptions);

$request ='<item xmlns="rmsItem">
      <columns>
        <column>description</column>
        <column>department</column>
        <column>brand</column>
        <column>lastsold</column>
        <column>lastupdated</column>
        <column>quantityonhand</column>
        <column>weight</column>
      </columns>
      <filters>
        <filter>
          <filterColumn>quantityonhand</filterColumn>
          <operator>greaterthan</operator>
          <filterValue>20</filterValue>
        </filter>
        <filter>
          <filterColumn>lastsold</filterColumn>
          <operator>greaterthan</operator>
          <filterValue>01-01-2005</filterValue>
        </filter>
      </filters>
      <sortColumns>
        <sortColumn>
          <sortColumnName>lastsold</sortColumnName>
          <sortType>ascending</sortType>
        </sortColumn>
        <sortColumn>
          <sortColumnName>quantityonhand</sortColumnName>
          <sortType>descending</sortType>
        </sortColumn>
      </sortColumns>
    </item>';

//$result = $client->__soapCall('getAllInfo',array('infoRequestXml'=>(string)($request),'errorMessage'=>'') ,array('soapaction' => 'http://webserviceurl/getAllInfo'));

$soapvar = new SoapVar($request , XSD_ANYXML);

$params = array("infoRequestXml" => $soapvar);

//print_r($params);
//$result = $this->soapclient->__soapCall("SaveItem", array("parameters"=>$params), null, $this->soapheaders);
try
{
$result=$client->__soapCall('getAllInfo',array("parameters"=>$params),array('soapaction' => 'http://webserviceurl/getAllInfo'));
}
catch (SoapFault $e) {
    echo "SOAP Fault: ".$e->getMessage()."<br />\n";
}
echo "<pre>\n";
echo htmlspecialchars($client->__getLastRequest())."\n";
echo "Response:\n".htmlspecialchars($client->__getLastResponse())."\n";
echo "</pre>"; 

var_dump($result);

?>

过去两天我一直在用头撞墙，在谷歌上搜索这个问题，但没有得到解决或指导我解决的答案。

任何能够阐明这一点的人都将受到高度赞赏。 提前致谢。

不要通过 SOAPVar 运行 XML，并且如果可以的话，请利用 Web 服务的 WSDL 选项：

<?php

$client = new SOAPClient(
    'http://webserviceurl.asmx?WSDL',
    array(
        'location' => 'http://webserviceurl.asmx',
        'trace' => 1,
        'style' => SOAP_RPC,
        'use' => SOAP_ENCODED,
    )
);

$request = '<item xmlns="rmsItem">
      <columns>
        <column>description</column>
        <column>department</column>
        <column>brand</column>
        <column>lastsold</column>
        <column>lastupdated</column>
        <column>quantityonhand</column>
        <column>weight</column>
      </columns>
      <filters>
        <filter>
          <filterColumn>quantityonhand</filterColumn>
          <operator>greaterthan</operator>
          <filterValue>20</filterValue>
        </filter>
        <filter>
          <filterColumn>lastsold</filterColumn>
          <operator>greaterthan</operator>
          <filterValue>01-01-2005</filterValue>
        </filter>
      </filters>
      <sortColumns>
        <sortColumn>
          <sortColumnName>lastsold</sortColumnName>
          <sortType>ascending</sortType>
        </sortColumn>
        <sortColumn>
          <sortColumnName>quantityonhand</sortColumnName>
          <sortType>descending</sortType>
        </sortColumn>
      </sortColumns>
    </item>';

$result = array();

$params = array("infoRequestXml" => $request);

try {
    $result = $client->__soapCall('getAllInfo', array("parameters"=>$params));
} catch (SoapFault $e) {
    echo "SOAP Fault: ".$e->getMessage()."<br />\n";
}

echo "<pre>";
echo htmlspecialchars($client->__getLastRequestHeaders())."\n";
echo htmlspecialchars($client->__getLastRequest())."\n";
echo "Response:\n".htmlspecialchars($client->__getLastResponseHeaders())."\n";
echo htmlspecialchars($client->__getLastResponse())."\n";
echo "</pre>"; 

var_dump($result);

?>
