("Accept-Encoding", "gzip, deflate");

[Guest]

Ok so I am reading To optimise performance and ensure that your application is interacting with the Betfair API as efficiently as possible, we strongly recommend the following as best practice and enable HTTP compression which I assume is adding

request.Headers.Add("Accept-Encoding", "gzip, deflate")


OK but where? I am using the CSharp example (ported to VB NET) and I have JsonRpcClient.vb which contains all the code to talk to API. Should I add this code into my constructor as follows

Public Sub New(ByVal endPoint As String, ByVal appKey As String, ByVal sessionToken As String)
'THIS CONSTRUCTOR ADDS THE URL AND THEN ADDS THE APPLICATION KEY AND SESSION TOKEN INTO OUR WEBREQUEST
Me.EndPoint = endPoint '& "/json-rpc/v1"
CustomHeaders = New NameValueCollection()
If appKey IsNot Nothing Then
CustomHeaders(APPKEY_HEADER) = appKey
'ADDED 13 MARCH 2017 AND HOPEFULLY SHOULD MAKE THE SYSTEM QUICKER?
'CustomHeaders("Accept-Encoding") = "gzip, deflate"
End If
If sessionToken IsNot Nothing Then
CustomHeaders(SESSION_TOKEN_HEADER) = sessionToken
End If
Me.Timeout = 10000
End Sub

OR in CreateWebRequest function

'################################################# ################################################## ###############
'### CREATE WEB REQUEST ###
'################################################# ################################################## ###############
Protected Function CreateWebRequest(ByVal uri As Uri) As WebRequest
Dim request As WebRequest = WebRequest.Create(New Uri(EndPoint))
request.Method = "POST"
request.ContentType = "application/json-rpc"
request.Headers.Add(HttpRequestHeader.AcceptCharse t, "ISO-8859-1,utf-8")
ServicePointManager.Expect100Continue = False

'ADDED 13 MARCH 2017 AND HOPEFULLY SHOULD MAKE THE SYSTEM QUICKER?
'request.Headers.Add("Accept-Encoding", "gzip, deflate")

request.Headers.Add(CustomHeaders)
Return request
End Function

I added both and tested but I get response errors so something wrong.

Hi Troy,
I initially tried using "request.Headers.Add("Accept-Encoding", "gzip, deflate")" but couldn't get it to work either.


I got mine to work by using this coding in the CreateWebRequest instead of of the above (VB):

request.AutomaticDecompression = DecompressionMethods.GZip
request.AutomaticDecompression = DecompressionMethods.Deflate


hope this helps, still trying to get "Streaming" to work with VB

It took me ages to get it working, but this (VB.NET) seems to do the trick:

request.Headers.Add("Content-Encoding: gzip")

This should be
request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

Otherwise the second line "DecompressionMethods.Deflate" will overwrite the first one.

I have streaming working with vb.net if you have any questions.

You have streaming in VB.net THEHUN10?
I tried to convert the whole c# project but i'm still struggling.

Hi,

I didn’t convert the c# examples to vb.net, I added the c# code to a vb.net project and called them from within a vb.net.
I create a c# form called ePathForm which calls the “Betfair.ESASwagger” example code.
So from my vb.net code I call my c# form (ePathForm) and the c# form calls the Betfair c# code.


1. Created a c# form called ePathForm, this c# form calls the c# examples “Betfair.ESASwagger” ect…

Code from the my c# (ePathForm): -
using Aping_cs.TO;
using Aping_cs.Json;
using System.Threading.Tasks;

using Betfair.ESAClient;
using Betfair.ESAClient.Auth;
using Betfair.ESAClient.Cache;
using Betfair.ESASwagger.Model;


namespace Aping_cs
{

public partial class ePathForm : Form
{
Public m_oePathForm As ePathForm = New ePathForm

.
.
.

public Boolean LoginJson(string strAppKey,
string strSessionToken,
ref string strErrorMsg)
{
try
{
client = new JsonRpcClient(Url, strAppKey, strSessionToken);
var marketFilter = new MarketFilter();
var eventTypes = client.listEventTypes(marketFilter);
return true;

}
catch (APINGException apiExcepion)
{
strErrorMsg="Got an exception from Api-NG: " + apiExcepion.ErrorCode;
return false;
}
catch (System.Exception e)
{
strErrorMsg="Unknown exception from application: " + e.Message;
return false;
}
}




2. The vb.net code is like this

Public m_oePathForm As ePathForm = New ePathForm

Public Function Login(ByRef strErrorMasg As String) As Boolean
Dim strErrorMsg As String
If m_oePathForm.LoginJson(strErrorMsg) Then
Return True
Else
Return False
End If
End Function
