class stdClass的對象無法轉換爲SOAP請求的字符串

Question

當我運行以下腳本時，我得到一個「class stdClass的對象無法轉換爲SOAP請求的字符串」錯誤$client->LatLonListZipCode($args)行和I無法弄清楚爲什麼。有任何想法嗎？

<?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);

異常原因

首先 - 這個服務被使用SOAP 1.1不SOAP 1.2。您$client規格更改爲：因爲它是在你的WSDL service specification表示

$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 

服務定義

，你可以找到LatLonListZipCode函數定義爲：

<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> 

和預期的參數定義爲：

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

適當的電話

所以我們知道，該服務器只需要一個string參數名爲zipCodeList。現在，我們可以扣除你的代碼應該是這樣的：

$args = array("zipCodeList"=>'10001'); 
try { 
$z = $client->LatLonListZipCode($args); 
} catch (SoapFault $e) { 
    echo $e->faultcode; 
} 

注意，我趕上SoapFault例外。它會幫助你理解服務器端錯誤。在PHP documentation閱讀更多關於它的信息。
