(413) Request Entity Too Large in WCF - asp.net

Question

Trying so send Array size of 1227136 and getting error 413
This is how I am sending the 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);
}

My WCF code where I am receiving the data when I am sending small amount of data then it is working fine. But I want to send large 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;
}

Answer 1

I have changed the WCf application app.config and solve the issue-
I have only 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>
