PHP SoapServer：如何禁用“响应”追加

Question

我正在创建一个 SOAP 服务器（在 Symfony 中使用 ckWebservicePlugin），它需要遵守以下请求和响应结构（我将此作为已商定的规范）。

请求：

<?xml version="1.0" encoding="UTF-8"?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.example.net/schemas/USSD">
  <SOAP-ENV:Header/>
  <SOAP-ENV:Body>
    <USSDMessageRequest>
      <id>43</id>
      <msid>1234567890</msid>
      <data>1*2</data>
    </USSDMessageRequest>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>  

响应：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
  <SOAP-ENV:Header/>
  <SOAP-ENV:Body>
    <USSDMessageResponse>
       <id>43</id>
       <msid>1234567890</msid>
       <data>
          RESPONSE DATA
       </data>
    </USSDMessageResponse>
</SOAP-ENV:Body>

我遇到的问题是 SoapServer 总是以请求方法的名称 + 附加“响应”的形式生成响应。

因此，发送的响应 XML 如下所示：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://bw.petr.appsdev/bw/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <SOAP-ENV:Body>
      <ns1:USSDMessageRequestResponse>
         <result>
            <id>2</id>
            <msid>1234565789</msid>
            <data>RESPONSE DATA</data>
         </result>
      </ns1:USSDMessageRequestResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我希望输出为 而不是 < ns1:USSDMessageRequestResponse>

The WSDL 我正在使用的看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" name="webservices" targetNamespace="http://bw.petr.appsdev/bw/" xmlns:tns="http://bw.petr.appsdev/bw/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">

已经检查了 SoapServer 文档，浏览了 R. Richards 的 Pro Xml And Web Services，但不能弄清楚如何告诉 SoapServer 响应名称应该是什么。

谢谢。

尝试这个肮脏的 SoapVar hack：

public function USSDMessageRequest() {
        $result = '<ns1:USSDMessageResponse> ... </ns1:USSDMessageResponse>'; // ns1 is dirty, depends on the SoapServer implementation
        $result = new SoapVar($result, XSD_ANYXML);
        return $result;
    }

它在类似的问题上对我有用（不过，我还没有用你的网络服务测试过它）。

您是否以 WSDL 模式创建 SoapServer？我的意思是你已经像这样构造了 SoapServer：

new SoapServer('path/to/wsdl', $options); 

第一个参数不能为空。然后 SoapServer 应该根据 WSDL 创建响应。如果您仍然遇到问题，请尝试使用最新版本的 PHP。
