WCF服務的異常消息

WCF Service發生異常的時候,客戶端一般只能看見這樣一個錯誤:“The server encountered an error PRocessing the request”,而異常的類型和引起異常的代碼都沒有顯示,究其原因是出于安全考慮。如果想要暴露這些異常信息的細節給客戶端,只需要在服務器的配置文件上修改<serviceDebug includeExceptionDetailInFaults="true" />。

(一)SOAP WCF Service的異常

(1) 當serviceDebug includeExceptionDetailInFaults="false"

IDemoService.cs:

using System.ServiceModel;namespace WCFDemo{        [ServiceContract(Name = "IDemoService")]    public interface IDemoService    {        [OperationContract]        int Divide(int numerator, int denominator);    }}

DemoService.cs:

using System;using System.ServiceModel.Activation;namespace WCFDemo{    [aspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]    public class DemoService : IDemoService    {        public int Divide(int numerator, int denominator)        {            return numerator / denominator;        }    }}

web.config

<?xml version="1.0"?> <configuration>     <system.web>       <compilation targetFramework="4.0" />     </system.web>    <system.serviceModel>       <services>         <service name="WCFDemo.DemoService" behaviorConfiguration="metaBehavior">           <endpoint address="DemoService" binding="basicHttpBinding" contract="WCFDemo.IDemoService" />           <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>           <host>             <baseAddresses>               <add baseAddress="http://localhost:8080"/>             </baseAddresses>           </host>         </service>       </services>         <behaviors>             <serviceBehaviors>                 <behavior name="metaBehavior">                     <serviceMetadata httpGetEnabled="true" />                     <serviceDebug includeExceptionDetailInFaults="false" />                 </behavior>             </serviceBehaviors>         </behaviors>         <serviceHostingEnvironment mult

建立一個Windows Client,Form1.cs:

private void buttonCalculate_Click(object sender, EventArgs e) {     DemoServiceReference.DemoServiceClient demoServiceClient = new DemoServiceReference.DemoServiceClient();     textBoxResult.Text = demoServiceClient.Divide(Convert.ToInt32(textBoxNumerator.Text), Convert.ToInt32(textBoxDenominator.Text)).ToString(); } 

Client app.config

<?xml version="1.0" encoding="utf-8" ?> <configuration>     <system.serviceModel>         <bindings>             <basicHttpBinding>                 <binding name="BasicHttpBinding_IDemoService" />             </basicHttpBinding>         </bindings>         <client>             <endpoint address="http://169.254.14.147:8080/DemoService.svc/DemoService"                 binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IDemoService"                 contract="DemoServiceReference.IDemoService" name="BasicHttpBinding_IDemoService" />         </client>     </system.serviceModel> </configuration>

在正常情況下的消息為:

Request Body:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">  <s:Body>    <Divide xmlns="http://tempuri.org/">      <numerator>100</numerator>      <denominator>10</denominator>    </Divide>  </s:Body></s:Envelope>

Response Body:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">  <s:Body>    <DivideResponse xmlns="http://tempuri.org/">      <DivideResult>10</DivideResult>    </DivideResponse>  </s:Body></s:Envelope>

在發生異常時:

Request Header:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">  <s:Body>    <Divide xmlns="http://tempuri.org/">      <numerator>100</numerator>      <denominator>0</denominator>    </Divide>  </s:Body></s:Envelope>

Response Body:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">  <s:Body>    <s:Fault>      <faultcode xmlns:a="http://schemas.microsoft.com/net/2005/12/windowscommunicationfoundation/dispatcher">a:InternalServiceFault</faultcode>      <faultstring xml:lang="en-US">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 &lt;serviceDebug&gt; 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 SDK documentation and inspect the server trace logs.</faultstring>    </s:Fault>  </s:Body></s:Envelope>

(2)當serviceDebug includeExceptionDetailInFaults="true"

可以看到異常的消息為”Attempted to divide by zero.”
