Hello

I have a problem with new okHttpClient and okHttprequest.initializepost2
I try to login on a web site like this:

B4X:
aHttp.InitializeAcceptAll("Http")
Url="https://www.xxxxx/ajax/login_valid.php"
Param="login="&myLogin&"&password="&my_MD5_Pass
aReq.InitializePost2(Url,Param.GetBytes("UTF8"))
aReq.SetHeader("User-Agent","Mozilla/5.0 (Android; Linux armv7l; rv:5.0) Gecko/20110615 Firefox/5.0 Fennec/5.0")
aHttp.Execute(aReq,1000)

In Http_ResponseError I receive a 401 error

Same code with previous HttpClient works well.

The javascript code on the website

B4X:
function valid()
{
jQuery('#errcode').attr('innerHTML', "");
var encode = String(md5(jQuery('#password').val()));
var url = './ajax/login_valid.php';
var parametres = 'login=' + escape(jQuery('#login').val()) + '&password=' + encode;
jQuery.ajax(
{
url:url,
type: 'POST',
data: parametres,
success: function(transport)
{
var response = transport ;
if (response == 'ok')
{
document.location.href = "./accueil.php";
}
else
{
jQuery('#errcode').attr('innerHTML', response) ;
}
},
error: function() { alert("ajax error"); }
});
}

is there a limitation or a diffrent implementation for okHttp and post method.
Others http get requests wors well

Thanks

It works fine here. Tested with this code:
B4X:
Sub Activity_Create(FirstTime As Boolean)
   Dim hc As OkHttpClient
   hc.InitializeAcceptAll("hc")
   Dim req As OkHttpRequest
   req.InitializePost2("link", "login=user&password=md5_password".GetBytes("UTF8"))
   req.SetHeader("User-Agent","Mozilla/5.0 (Android; Linux armv7l; rv:5.0) Gecko/20110615 Firefox/5.0 Fennec/5.0")
   hc.Execute(req,1000)
End Sub


Sub hc_ResponseSuccess (Response As OkHttpResponse, TaskId As Int)
   Dim out As OutputStream
   out.InitializeToBytesArray(0)
   Response.GetAsynchronously("res", out, False, TaskId)
End Sub

Sub res_StreamFinish (Success As Boolean, TaskId As Int)
   Log($" ${Success}"$)
   If Success Then Log(BytesToString(out.ToBytesArray, 0, out.ToBytesArray.Length, "utf8"))
End Sub


Sub hc_ResponseError (Response As OkHttpResponse, Reason As String, StatusCode As Int, TaskId As Int)
   Log($"Error: ${Response.ErrorResponse}, ${Reason}, ${StatusCode}"$)
   If Response <> Null Then Response.Release
End Sub

I don't understand what is the difference between ok http library and httputlis 2.1 ?

The OkHTTP is just the library, HTTPUtils is a tool using the OkHTTP library.
so i must only download the "httputlis2.zip" and use it , without worrying about the other attachment "okhttp.zip" right ?

If you want to use HttpUtils2 v2.1 then you need to also download OkHttp as it depends on it.

OK i have to download both and but them in the internal libraries folder and include both in my project then use htpputlis as usual ?

I keep getting a noClassDefFound error regarding httpjob when trying to use this. I added the modified httputils2 library as well as the okhttp library.

Is this because I am using an older version of b4a? 2.52 to be exact.
