我如何调查WCF提供400错误的请求过得到什么？ [英] How do I investigate WCF giving 400 bad request over GET?

问题描述

下面的WCF端点工作得很好用WCF测试客户端：

The following WCF endpoint works just fine with the WCF test client:

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Xml,
        BodyStyle = WebMessageBodyStyle.Bare,
        UriTemplate = "listflaggedassets/{platform}?endpoint={endpoint}&pid={portalid}&processCode={processCode}&index={index}&limit={limit}")]
AssetList ListFlaggedAssets(short processCode, string platform, string endpoint = "null", string portalId = "null", int index = 0, int limit = 12);

然而，当我试图导航到网址的http：//本地主机/DigitalREST/XosAssets.svc/listflaggedassets/SEC?endpoint=superfan&pid=0&processCode=0&index=0&limit=20 我得到一个400错误的请求。

However, when I attempt to navigate to the URL http://localhost/DigitalREST/XosAssets.svc/listflaggedassets/SEC?endpoint=superfan&pid=0&processCode=0&index=0&limit=20 I get a 400 bad request.

我似乎无法找到任何方式来弄清楚为什么我得到一个错误的请求，并连接到IIS调试任何异常不破。

I can't seem to find any way to figure out WHY i'm getting a bad request, and attaching to IIS for debugging doesn't break on any exceptions.

我怎么能调查错误请求的原因是什么？

推荐答案

您可以启用跟踪并使用服务跟踪查看

You could enable tracing and use Service Trace Viewer

降这到你的app.config（来源登录从这个答案服用）：

Drop this into your app.config (logging sources taken from this answer):

<system.diagnostics>
    <sources>
      <source name="System.ServiceModel"
              switchValue="Information, ActivityTracing"
              propagateActivity="true" >
        <listeners>
          <add name="xml"/>
        </listeners>
      </source>
      <source name="System.ServiceModel.MessageLogging">
        <listeners>
          <add name="xml"/>
        </listeners>
      </source>
      <source name="myUserTraceSource"
              switchValue="Information, ActivityTracing">
        <listeners>
          <add name="xml"/>
        </listeners>
      </source>
    </sources>
    <sharedListeners>
      <add name="xml"
           type="System.Diagnostics.XmlWriterTraceListener"
           initializeData="TraceLog.svclog" />
    </sharedListeners>
  </system.diagnostics>

然后，打开服务跟踪查看器的TraceLog.svclog。它可能不会告诉你到底发生了什么事情，但它会提供有关交通和异常本身的细节。

Then, open the TraceLog.svclog in Service Trace Viewer. It may not tell you exactly what's going on, but it will provide details about the traffic and the exception itself.

您可能还需要检查在启用例外调试器。在Visual Studio中，转到调试 - >例外，并检查是否有正确的框架进行检查。

You may also want to check the exceptions you have enabled in the debugger. In Visual Studio, go to Debug -> Exceptions and check that you have the correct framework checked.
