(413) Request object too large in WCF

Question

Trying to send an Array of size 1227136 and get error 413

This is how I send data from a wreb application -

protected void Page_Load(object sender, EventArgs e) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:59624/RestServiceImpl.svc/PostFileRest");//Path for local request.Timeout = Timeout.Infinite; request.KeepAlive = true; request.ContentType = "application/vnd.ms-excel"; /*---------------------------------------------------------------------------*/ string excelTojson = excelToJson(); byte[] fileData = Encoding.ASCII.GetBytes(excelTojson); /*---------------------------------------------------------------------------*/ request.ContentLength = fileData.Length; Stream requestStream = request.GetRequestStream(); requestStream.Write(fileData, 0, fileData.Length); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); System.Diagnostics.Debug.Assert(response.StatusCode == HttpStatusCode.OK); string responseMessage = string.Empty; using (System.IO.StreamReader sr = new System.IO.StreamReader(response.GetResponseStream())) { responseMessage = sr.ReadToEnd(); } Response.Write(responseMessage); } #region excelToJson public string excelToJson() { var pathToExcel = @"E:\My_Work\MVC\Test1.xlsx"; OleDbConnection MyConnection; DataTable dt; OleDbDataAdapter MyCommand; MyConnection = new OleDbConnection("provider=Microsoft.ACE.OLEDB.12.0;Data Source='" + pathToExcel + "';Extended Properties='Excel 12.0 Xml;HDR=YES'"); MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", MyConnection); MyCommand.TableMappings.Add("Table", "TestTable"); dt = new DataTable(); MyCommand.Fill(dt); MyConnection.Close(); string jsonString = string.Empty; return jsonString = JsonConvert.SerializeObject(dt); } #endregion 

My WCF code is where I get data when sending a small amount of data, then it works fine. But I want to send big data.

 [ServiceContract] public interface IRestServiceImpl { [OperationContract] [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "PostFileRest")] string PostFileRest(Stream fileContents); } public class RestServiceImpl : IRestServiceImpl { public string PostFileRest(Stream fileContents) { var httpRequest = HttpContext.Current.Request; //var filePath = "C:\\file.xls"; //excel filePath for local //var filePath = "D:\\Forecast\\ExcelOutput\\output.xls"; //excel filePath for 19 server //StreamReader r = new StreamReader(HttpContext.Current.Request.InputStream); //string jsonBody = r.ReadToEnd(); // jsonBody is empty!! var bites = httpRequest.TotalBytes; //Convert stream to byte array byte[] reqBytes = readRequest(fileContents, bites); byte[] decodedReqBytes = HttpUtility.UrlDecodeToBytes(reqBytes); string json = System.Text.Encoding.UTF8.GetString(reqBytes); DataTable dt = JsonConvert.DeserializeObject<DataTable>(json); //MemoryStream stream = new MemoryStream(reqBytes); //FileStream file = new FileStream(filePath, FileMode.Create, FileAccess.Write); //stream.WriteTo(file); //file.Close(); //stream.Close(); string responseJson = TalkToDll.ForecastData(dt); return responseJson; } #region Convert Stream to byte array private byte[] readRequest(Stream fileContents, int bites) { System.IO.MemoryStream memStream = new System.IO.MemoryStream(); int BUFFER_SIZE = bites; int iRead = 0; int idx = 0; Int64 iSize = 0; memStream.SetLength(BUFFER_SIZE); while (true) { byte[] reqBuffer = new byte[BUFFER_SIZE]; try { iRead = fileContents.Read(reqBuffer, 0, BUFFER_SIZE); } catch (System.Exception e) { System.Diagnostics.Debug.WriteLine(e.Message); } if (iRead == 0) { break; } iSize += iRead; memStream.SetLength(iSize); memStream.Write(reqBuffer, 0, iRead); idx += iRead; } byte[] content = memStream.ToArray(); memStream.Close(); return content; } #endregion } 

My app.config is

I changed the app.config application for WCf and solved the problem -

I just add bindingConfiguration = "myBinding" and change basicHttpBinding to webHttpBinding. Here is the new code -

 <bindings> <webHttpBinding> <binding name="myBinding" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" transferMode="Streamed" > <readerQuotas maxDepth="64" maxArrayLength="2147483647" maxStringContentLength="2147483647"/> </binding> </webHttpBinding> </bindings> <services> <service behaviorConfiguration="ForecastREST_API.RESTServiceImplBehavior" name="ForecastREST_API.RestServiceImpl"> <endpoint address="http://localhost:59624/RestServiceImpl.svc" binding="webHttpBinding" contract="ForecastREST_API.IRestServiceImpl" behaviorConfiguration="Web" bindingConfiguration="myBinding"> </identity> </endpoint> <endpoint address="mex" binding="webHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <endpointBehaviors> <behavior name="Web"> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> <webHttp defaultOutgoingResponseFormat="Json" automaticFormatSelectionEnabled="true" /> <dispatcherSynchronization asynchronousSendEnabled="true" /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="ForecastREST_API.RESTServiceImplBehavior"> <dataContractSerializer maxItemsInObjectGraph="2147483647" /> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> </behaviors>
