调用Web服务时出错 [英] Error while calling a Webservice

问题描述

先生，
我正在使用以下代码来调用Web服务:

Sir,
I am using below code to call the web service:

ApplicationItemEx[] items = proxy.GetApplicationsByCredentialsEx(credentials, Request.UserHostName, Request.UserHostAddress, new string[] { "icon", "icon-info" }, new string[] { "all" }, new string[] { "all" });

但是我用来调用Web服务的上述声明给了我如下所示的错误:

But the above declaration i use to call the webservice gives me an error shown below:

Error:
System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction:

请让我知道还有其他方法可以调用Web服务吗?为什么会出现此错误?

Please let me know is there any another way to call the web service? Why I am getting this error?

-Basheer

推荐答案

您能提供更多信息吗? Web服务是否公开了SOAP接口?

您正在使用WSE3客户端吗?

Can you give more information? Is the webservice exposing a SOAP interface?

Are you using a WSE3 client?
