    text
    copied!<p>I have a WCF service that returns JSON to the clients.</p> <p>This is the app.config</p> <pre><code> &lt;system.serviceModel&gt; &lt;services&gt; &lt;service name="MyServices.MyService"&gt; &lt;endpoint address="" behaviorConfiguration="JsonBehavior" binding="webHttpBinding" contract="Myervices.IMyervice"&gt; &lt;identity&gt; &lt;dns value="localhost" /&gt; &lt;/identity&gt; &lt;/endpoint&gt; &lt;endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /&gt; &lt;host&gt; &lt;baseAddresses&gt; &lt;add baseAddress="http://localhost:8732/Design_Time_Addresses/MyEmulator/Service1/" /&gt; &lt;/baseAddresses&gt; &lt;/host&gt; &lt;/service&gt; &lt;/services&gt; &lt;behaviors&gt; &lt;serviceBehaviors&gt; &lt;behavior&gt; &lt;serviceMetadata httpGetEnabled="True"/&gt; &lt;serviceDebug includeExceptionDetailInFaults="True"/&gt; &lt;/behavior&gt; &lt;/serviceBehaviors&gt; &lt;endpointBehaviors&gt; &lt;behavior name="JsonBehavior"&gt; &lt;webHttp /&gt; &lt;/behavior&gt; &lt;/endpointBehaviors&gt; &lt;/behaviors&gt; </code></pre> <p></p> <p>This is a sample opertaion exposed by the service</p> <pre><code> [OperationContract] [WebInvoke(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, Method = "GET", UriTemplate = "me/{id}")] JsonObject GetObject(string id, string connection_type); </code></pre> <p>Now, I would like to log every request that the service receives from clients and response that is being sent back to clients...in this case it sin JSOn.</p> <p>I have create a custom MessageInspector as follows</p> <pre><code>public class MyMessageInspector : IDispatchMessageInspector { private bool LoggingEnabled; #region IDispatchMessageInspector Members public object AfterReceiveRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel, System.ServiceModel.InstanceContext instanceContext) { Guid correlationState = Guid.NewGuid(); if (this.LoggingEnabled) { StringBuilder message = new StringBuilder(); message.AppendFormat("CorrelationState = {0}{1}", correlationState, Environment.NewLine); message.AppendFormat("Local Address = {0}{1}", channel.LocalAddress, Environment.NewLine); message.AppendFormat("Remote Address = {0}{1}", channel.RemoteAddress, Environment.NewLine); message.AppendLine("Request"); message.AppendLine(request.ToString()); message.AppendLine(); this.logger.LogMessage(message.ToString()); } return correlationState; } public void BeforeSendReply(ref System.ServiceModel.Channels.Message reply, object correlationState) { if (this.LoggingEnabled) { StringBuilder message = new StringBuilder(); message.AppendFormat("CorrelationState = {0}{1}", correlationState, Environment.NewLine); message.AppendLine("Reply"); message.AppendLine(reply.ToString()); message.AppendLine(); this.logger.LogMessage(message.ToString()); } } #endregion } </code></pre> <p>But this doesnt seem to log any of the resposne.. the response.Tostring() only says "...stream"</p> <p>the Above works if my service returns data in SOAP XML format..but i want it to log JSON response which is the text inside the *.js file downloaded in the browser when i call the REST service endpoint. ex: <a href="http://localhost:8080/MyService/me/2/" rel="nofollow">http://localhost:8080/MyService/me/2/</a></p> <p>any ideas how I can achieve this?</p>
