Asp.net 测试web服务的基本post

我正在制作表单，它通过post向webservice发送输入并显示结果。它必须简单，并且在本地主机上运行良好。但当我尝试再次使用它时，我有错误500

这是我的密码：

 WebRequest request = WebRequest.Create("http://localhost:3192/WebServices/Export.asmx/" + uxAction.SelectedValue);
                UTF8Encoding encoding = new UTF8Encoding();
                byte[] data = encoding.GetBytes(uxRequest.Text);
                request.Method = "POST";
                request.ContentType = "text/xml; charset=utf-8";
                request.ContentLength = data.Length;

                Stream requestStream = request.GetRequestStream();
                requestStream.Write(data, 0, data.Length);
                requestStream.Flush();
                requestStream.Close();

                WebResponse response = request.GetResponse();
                Stream newStream = response.GetResponseStream();
                byte[] responseArray = new byte[response.ContentLength];
                newStream.Read(responseArray, 0, (int)response.ContentLength);
                newStream.Close();

                uxResponse.Text = encoding.GetString(responseArray);

这是关于错误的信息

 Exception information: 
        Exception type: InvalidOperationException 
        Exception message: Request format is unrecognized for URL unexpectedly ending in '/GetProjectTypes'. 

    Request information:

   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

我还使用http处理程序从javascript访问web服务，这很好：

<add verb="GET,HEAD,POST*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

这是我的请求数据。有或没有异常都是一样的。Webservice没有任何参数

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetProjectTypes xmlns="http://sitename.com/WebServices/Export.asmx" />
  </soap:Body>
</soap:Envelope>

当我们在浏览器中测试webservice时，它会将methodname添加到url中，但当我们发布时，这是不需要的。

我删除了“/”+uxAction.SelectedValue”，现在一切都正常了

您的帖子数据编码正确吗（

HttpUtility.UrlEncode（）

等）？我应该为xml数据执行此操作吗？在xml内部，一切都非常简单请演示如何填充

数据
变量它类似于：我从示例SOAP 1.1指令中获取它。但是，没有此数据，结果是相同的。我的方法没有任何参数
