PHP - 创建并调用 SOAP Web 服务 - 错误

Question

每次我尝试通过 wsdl 调用我的 Web 服务时，我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：

 [22-Sep-2011 18:54:46] PHP Fatal error:  Uncaught SoapFault exception:
 [HTTP] Not Found in /www/zendserver/htdocs/dev/csc/request.php:4
 Stack trace:
 #0 [internal function]: SoapClient->__doRequest('<?xml version="...',
 'http://192.168....', 'http://www.exam...', 1, 0)
 #1 [internal function]: SoapClient->__call('EchoText', Array)
 #2 /www/zendserver/htdocs/dev/csc/request.php(4):
 SoapClient->EchoText('test')
 #3 {main}   thrown in /www/zendserver/htdocs/dev/csc/request.php on
 line 4

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($text){
    return "ECHO: ".$text;
}

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

?>

我有一个接口页面，这是我访问的页面，然后出现上面显示的错误，位于： http://192.168.1.2:10088/csc/request.php

<?php
$client = new SoapClient("http://192.168.1.2:10088/csc/NewWSDLFile.wsdl");

$result = $client->EchoText("test");
echo $result;
>?

Answer 1

肥皂故障=> Not Found 是指 SoapClient 无法到达服务器。

192.168.1.2是本地IP地址，Web服务器也在本地网络上吗？否则这就是您的客户无法工作的原因。
