WCF服务启用跟踪

Question

经过两天的尝试和错误以及盲目调试后，我的网络服务在某些情况下仍会产生一些错误，目前我还不知道为什么。 因此，我想启用对服务的跟踪，以便至少得到一些反馈。

但是，我尝试了一些web.config的添加，但是没有一个生成跟踪文件，即使服务响应错误。

这么久，这是我的web.config：

我已经查找了跟踪的配置并测试了web.config的条目，例如{。{3}}，here，并且还阅读了here。

正如文档中所写，从Windows 8开始，您需要特权才能进行跟踪，我还更改了应用程序池标识，但没有成功（该服务在Win 2012 R2服务器上运行）。 / p>

为了启用和使用跟踪，我缺少什么？ 提前感谢您的努力！

web.config中需要两个部分，一个是配置了tracelisteners的部分，另一个是system.serviceModel中的诊断部分。

System.Diagnostics程序

添加以下部分：

$("#reservationform").submit(function(e) {
      e.preventDefault();
        var url = document.getElementById('reservationform').action,
            fromDate = document.getElementById('checkin').value,
            toDate = document.getElementById('checkout').value,// the script where you handle the form input.
            dataString = 'fromDate=' + fromDate + '&toDate=' + toDate;
        $.ajax({
            type: "GET",
            url: url,
            data: dataString,
            success: function(name)
            {
                document.getElementById('rooms').innerHTML = name;
            }, 
            complete: function() {
               $("button#check").css("display", "none");
              $("button#book").css("display", "block");
            }
        });
         // avoid to execute the actual submit of the form.

    });

注意use Sonata\AdminBundle\Route\RouteCollection; 的值，并确保在那里添加应用程序标识可以写入的路径。系统范围的临时文件夹应该是一种选择。

system.serviceModel diagniostics

调整您的<system.diagnostics> <sources> <source name="System.ServiceModel.MessageLogging"> <listeners> <add name="messages" type="System.Diagnostics.XmlWriterTraceListener" initializeData="c:\temp\messages.svclog" /> </listeners> </source> <source name="System.ServiceModel" switchValue="Information,ActivityTracing" propagateActivity="true"> <listeners> <add name="tracing" type="System.Diagnostics.XmlWriterTraceListener" initializeData="c:\temp\tracing.svclog" /> </listeners> </source> </sources> </system.diagnostics> 并添加诊断设置

initializeData

测试您的设置

使用上面的配置，您的日志文件应该被创建，system.serviceModel应该在服务启动时或您为服务请求wsdl时显示条目。它还包含发生的任何异常和堆栈跟踪。
