对象没有在属性中 - php Soap wsdl

Question

每次我尝试通过 wsdl 调用我的 Web 服务时，都会收到此处显示的错误消息。我认为这可能是 WSDL 定义中的一个问题，因为我不太确定我在 WSDL 定义中首先做什么：

PHP Fatal error: SOAP-ERROR: Encoding: object has not 'in' property in / www/zendserver/htdocs/dev/csc/csc.php 第 10 行

我有一个非常简单的 Web 服务，位于：

http://192.168.1.2:10088/csc/csc.php

<?php

function EchoText($text){
    return $text;
}

$server = new SoapServer("http://192.168.1.2:10088/csc/csc.wsdl",
                         array('uri' => "http://192.168.1.2:10088/csc/csc.php"));
$server->addFunction('EchoText');
$server->handle();

?>

我有一个接口页面，我访问该页面，然后收到上面显示的错误，位于：

http:// /192.168.1.2:10088/csc/request.php

<?php
try{
    $client = new SoapClient("http://192.168.1.2:10088/csc/csc.wsdl", array('trace'=>1));
    $result = $client->EchoText("test");
    echo $result;
} catch (Exception $e) {
    print_r($e);
}
>?

我有我的 WSDL，位于：
