web服务相关的问题或技巧

1.wcf怎么记录详细错误日志?

调用wcf时日志记录如下：

System.ServiceModel.FaultException: The server was unable to process the request due to an internal error.  For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs.

Server stack trace:
at System.ServiceModel.Channels.ServiceChannel.ThrowIfFaultUnderstood(Message reply, MessageFault fault, String action, MessageVersion version, FaultConverter faultConverter)
at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc& rpc)
at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout)
at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

Exception rethrown at [0]:
at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)
at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)

at最上层方法名称

at最上层方法路径

这些提示不能准确的判断出是哪里出了问题

解决办法是修改下wcf站点的配置文件

    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>

includeExceptionDetailInFaults="true"，可以返回错误详情

2.webservice中wse加密

调用webservice时出错信息：

System.Web.Services.Protocols.SoapHeaderException: Header http://schemas.xmlsoap.org/ws/2004/08/addressing:Action for ultimate recipient is required but not present in the message. 在 System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) 

原因是webservice加密了，调用时需要传token

2.1　Install-Package Microsoft.Web.Services3

2.2　public partial class WebService : System.Web.Services.Protocols.SoapHttpClientProtocol

修改为public partial class WebService : WebServicesClientProtocol

2.3代码示例：

        private static void Main(string[] args)
        {
            WebService webService = new WebService();
            UsernameToken token = new UsernameToken("testaccount", "123456", PasswordOption.SendNone);
            webService.RequestSoapContext.Security.Tokens.Add(token);
            string[] ret = webService.GetAccountInfo("000");            
            Console.ReadKey();
        }
