我正在执行第一次SOAP api任务。我需要从TriSource调用SOAP api，如下所示。
我搞不清楚，下面的代码出了什么问题。
<?php
$wsdl = "https://www.nobel-net.com/TSS_LOAD/TSS_LOAD.asmx?WSDL";// getcwd().'/TriSource.wsdl';
$options = array('soap_version' => SOAP_1_2, 'trace' => 1, 'exceptions' => 1);
$client = new SoapClient($wsdl, $options);
// output of : var_dump($client->__getFunctions());
// array (size=4)
// 0 => string 'SandboxResponse Sandbox(Sandbox $parameters)' (length=44)
// 1 => string 'BoardResponse Board(Board $parameters)' (length=38)
// 2 => string 'SandboxResponse Sandbox(Sandbox $parameters)' (length=44)
// 3 => string 'BoardResponse Board(Board $parameters)' (length=38)
$xmlBody = 'this is a long xml stirng';
try
{
$args = new SoapVar(new SoapVar($xmlBody, XSD_ANYXML),SOAP_ENC_OBJECT);
// alternate try
// $args = array(new SoapVar($xmlBody, XSD_ANYXML));
$res = $client->Sandbox($args);
}
catch (SoapFault $e)
{
var_dump($e);
}
我总是对Soap有以下错误。
object(SoapFault)[4]
protected 'message' => string 'System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> TSS_Load+ProgramError: Error writing Usage log.
Object reference not set to an instance of an object.
at TSS_Load.XML_Reader.AddLog(String Usage, String UserID, String Result, String Data) in c:'inetpub'wwwroot'TSS_LOAD'App_Code'TSS_Load.cs:line 3365
at TSS_Load.Sandbox(String sData) in c:'inetpub'wwwroot'TSS_LOAD'App_Code'TSS_Load.cs:line 44
--- End of inner exception stack trace ---' (length=485)
我发现了我的错误。我准备SOAP论证的方式不对。根据wsdl，沙盒类型如下。
// Class with sData string member
class Sandbox
{
string sData;
}
SOAP变量，如下所示。
// PHP code
$args = array('sData'=>new SoapVar($xmlBody, XSD_ANYXML));
