解析 SOAP 负载的 XML 错误:保留的 XML 名称 [英] XML error parsing SOAP payload: Reserved XML Name

问题描述

我有一个非常简单的网络服务，它返回一个字符串(硬编码).我在解析 SOAP 有效负载时不断收到错误:保留的 XML 名称.

I have a very simple web service that returns a string (hardcoded at that). I keep getting an error while parsing SOAP payload : Reserved XML Name.

我可以查看 WSDL 没问题(防火墙内部/后面，所以没有提供链接).

I can view the WSDL no problem (interal/behind firewall, so no link to provide).

这是调用我的方法后 NuSOAP 客户端的部分转储:

Here's a partial dump of the NuSOAP client after having called my method:

在 SOAP 正文中，您可以看到SomeText"，它是从我的仅包含一种方法的 Web 服务返回的硬编码内容:

In the SOAP body, you can see "SomeText" which is the hard coded content that is returned from my web service that contains only one method:

$server->register('vms_ws_list_files',
  array('password' => 'xsd:string'),      // Password check
  array('return' => 'xsd:string'),     // Output parameters
    $ns,                                  // namespace
    $ns . '#vms_ws_list_files',                 // soapaction
    'rpc',                                // style
    'encoded',                            // use
    'Get list of files on disk'                       // documentation
  );

...

function vms_ws_list_files($password){
    global $site;
    // Check password
    if ($password != 'myHardCodedPwdForTesting') {
        return new soap_fault('Wrong password!', '', '');
    }
    $out = "SomeText";

    return $out;
}

就我而言，端口 443 不受保护，因为它是内部/测试端口.

In my case, port 443 isn't protected as it's internal/testing.

推荐答案

去除 <?xml 和 然后它工作.如果不能，也许您可​​以在解释之前更改/扩展 nusoap 类以 trim 响应.额外的空白很可能来自 <?php & 之外的一些意外空白.?> 标签.

Remove the whitespace before <?xml and then it works. If you can't, maybe you can alter/extend the nusoap class to trim the response before interpretation. Most likely the extra whitespace comes from some accidental whitespace outside the <?php & ?> tags.
