Question

我已经获得了一个旧的web服务.asmx来使用，虽然代码在调试模式下工作正常（VS在本地主机上播放调试）当我尝试编写一个消费者应用程序来传递相关的SOAP请求以获得响应时我无法让它发挥作用。

在.NET中，我得到状态415不支持的媒体类型（之前从未听说过） - 科技问我发送了什么媒体我说文本是XML。

以下是所有代码和调试。我甚至尝试编写ASP经典版本，但根据SOAP版本得到不同的错误。

Web服务在一台服务器上。我正试图从我的本地机器和另一台服务器上消费。

WebMethods都在.amsx文件中，例如

[WebMethod]
public string GetName(string ClientHash)
{
}

在调试模式下从VS在localhost上运行它可以解决问题。将文件复制到IIS设置中的网站，名为http://webservice.demo.co.uk

其中包含以下文件夹结构

webservice.demo.co.uk/http.demo/App_Data（空） webservice.demo.co.uk/http.demo/bin-WebService.dll-WebService.pdb webservice.demo.co.uk/http.demo/properties-AssemblyInfo webservice.demo.co.uk/http.demo/-WebService.asmx -Web.Config

这些是SOAP请求示例，它们来自VS 2010中的调试按钮，它在端口上的本地主机上运行） - 工作正常，例如

POST /WebService.asmx HTTP/1.1
Host: localhost
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <GetName xmlns="http://tempuri.org/">
      <ClientHash>string</ClientHash>
    </GetName>
  </soap12:Body>
</soap12:Envelope>

所以我刚刚用我的服务器上的URL替换了host等的值，等等

这些是我的ASP尝试

Soap 1.1示例ASP Classic

POST /WebService.asmx HTTP/1.1
Host: webservice.demo.co.uk
Content-Type: text/xml; charset=utf-8

所以根元素丢失了吗？什么？并且Server无法识别HTTP Header SOAPAction的值：/ GetName。

那么我做错了什么？

我知道.asmx已经过时但我接管了这个项目。

我只需要一个消费者应用程序，可以在本地主机上从VS到服务器或服务器到服务器，显然可以使用VS.

为什么会有这么多错误

什么是不支持的媒体类型错误415？

我该如何解决？

使用ASMX Web服务获取SOAP错误，例如不支持的媒体类型
