我正在开发一个asp.net webapplication,用C#构建。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,到目前为止一直很好。
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soap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Web服务的响应中发现了一些奇怪的内容,如原始输出中所示:

标题正确显示。响应被编码并需要被解码。 SoapUI和Fiddler都能够解码响应,但代理类不能并且返回null。
我该如何克服这个问题?非常感谢任何帮助!
修改
调用服务的方式:
LisenceServiceFR.ServiceRegistration_PortTypeClient client = new LisenceServiceFR.ServiceRegistration_PortTypeClient();
LisenceServiceFR.aVehicleInfo info = client.getVehicleInfo("xxx", "xxx", licensePlate, "localhost");
编辑2:
来自Fiddler的响应XML。
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://services.audaconfr.com/ServiceRegistration.wsdl">

答案 0 :(得分:0)
我最终使用HttpWebRequest来调用webservice:
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 */
这不是我想要的解决方案,但它的作用就像一个魅力。
