无法将类stdClass的对象转换为SOAP请求的字符串

Question

当我运行以下脚本时，我得到一个＆＃34; 类stdClass的对象无法转换为SOAP请求的字符串＆＃34; $client->LatLonListZipCode($args)行上的错误，我无法弄清楚原因。有什么想法吗？

<?php
$contextOptions = array(
            'ssl' => array(
                'verify_peer'   => false,
                'verify_peer_name' => false,
                'allow_self_signed' => true
            ),
            'http' => array(
                'timeout' => 5 //seconds
            )
 );

//create stream context
$stream_context = stream_context_create($contextOptions);

//create client instance (over HTTPS)
$client = new SoapClient('http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl', array(
            'cache_wsdl'  => WSDL_CACHE_NONE,
            'exceptions' => 1,
            'trace' => 1,
            'stream_context' => $stream_context,
            'soap_version'=> SOAP_1_2,
            'connection_timeout' => 5 //seconds
));//SoapClient

$args = new stdClass();
$args->zipCodeList = '10001';

$z = $client->LatLonListZipCode($args);

异常原因

首先 - 此服务使用 SOAP 1.1 而不是 SOAP 1.2 。将您的$client规范更改为：

$client = new SoapClient('http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl', array(
            'cache_wsdl'  => WSDL_CACHE_NONE,
            'exceptions' => 1,
            'trace' => 1,
            'stream_context' => $stream_context,
            'soap_version'=> SOAP_1_1,//<-- note change here
            'connection_timeout' => 5 //seconds
));//SoapClient

服务定义

正如您在WSDL service specification中所述，您可以发现LatLonListZipCode函数定义为：

<operation name="LatLonListZipCode">
    <documentation>Returns a list of latitude and longitude pairs with each pair corresponding to an input zip code.</documentation>
    <input  message="tns:LatLonListZipCodeRequest"/>
    <output message="tns:LatLonListZipCodeResponse"/>
</operation>

和预期参数定义为：

<xsd:simpleType name="zipCodeListType">
    <xsd:restriction base='xsd:string'>
        <xsd:pattern value="\d{5}(\-\d{4})?( \d{5}(\-\d{4})?)*" />
    </xsd:restriction>
</xsd:simpleType>

正确的电话

我们知道，该服务器只需要一个名为string的{​​{1}}参数。现在我们可以推断出您的代码应该是这样的：

zipCodeList

请注意，我抓住$args = array("zipCodeList"=>'10001'); try { $z = $client->LatLonListZipCode($args); } catch (SoapFault $e) { echo $e->faultcode; } 例外。它将帮助您了解服务器端错误。请在PHP documentation中了解详情。
