我正在开发一个用 C# 构建的 asp.net web 应用程序。我必须实现使用 PHP 创建的第三方 Web 服务。这是一个非常简单的服务，只包含一个功能。我使用 wsdl 添加了服务引用，到目前为止一切顺利。

当我使用正确的参数调用 Web 服务函数时，它总是返回 null。我开始使用 SoapUI 进行故障排除。我从应用程序中捕获了肥皂消息并将其粘贴到 SoapUI 中，执行它并返回正确的消息。使用 Fiddler，我在来自 web 服务的响应中发现了一些奇怪的东西，如原始输出所示：

标题显示正确。响应已编码，需要解码。SoapUI 和 Fiddler 都能够解码响应，但代理类不能并返回 null。

我该如何克服这个问题？任何帮助是极大的赞赏！

服务调用方式：

LisenceServiceFR.ServiceRegistration_PortTypeClient client = new LisenceServiceFR.ServiceRegistration_PortTypeClient();
LisenceServiceFR.aVehicleInfo info = client.getVehicleInfo("xxx", "xxx", licensePlate, "localhost");

来自 Fiddler 的响应 XML。

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://services.audaconfr.com/ServiceRegistration.wsdl">

                &lt;carr&gt;MONOSPACE COMPACT&lt;/carr&gt;
                &lt;carr_cg&gt;CI&lt;/carr_cg&gt;
                &lt;co2&gt;152&lt;/co2&gt;
                <!-- etc -->
            &lt;/vehicule&gt;

            </aVehicle>
        </SOAP-ENV:getVehicleInfoResponse>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我最终使用 HttpWebRequest 来调用网络服务：

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.InnerXml = xml;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(endPoint);
req.Timeout = 100000000;

if (proxy != null)
    req.Proxy = new WebProxy(proxy, true);

req.Headers.Add("SOAPAction", "");
req.ContentType = "application/soap+xml;charset=\"utf-8\"";
req.Accept = "application/x-www-form-urlencoded"; 
req.Method = "POST";
Stream stm = req.GetRequestStream();
doc.Save(stm);
stm.Close();
WebResponse resp = req.GetResponse();
stm = resp.GetResponseStream();
StreamReader r = new StreamReader(stm);
string responseData = r.ReadToEnd();

XDocument response = XDocument.Parse(responseData);

/* extract data from response */

这不是我正在寻找的解决方案，但它就像一个魅力。
