Hi all, i am busy with the socket example:sign0085:
I need to log-in at my server with a username and password.
when i look at the data what enters the server, no username or password is given, in fact i see nothing at all.
the socket is connected because i have no Message

What do i wrong?

If Successful = False Then
Msgbox(LastException.Message, "Error connecting")
Return
End If

Dim tw As TextWriter

tw.Initialize(Socket1.OutputStream)

tw.WriteLine("GET /?status")
tw.WriteLine("Authorization: Basic axxxxxxxxxxx")
tw.WriteLine("Host: www.xxxxxx.nl")


greetings and tnx in advance, Henk

It will be much easier to use the Http library or HttpUtils instead of implementing the protocol yourself.

Hi Erel, i have done that but here the same problem.:BangHead:

'Activity module
Sub Globals
Dim b4a As String
b4a = "http://xx.xx.x.108:4000"
End Sub

Sub Activity_Create (FirstTime As Boolean)
HttpUtils.CallbackActivity = "Main" 'Current activity name.
HttpUtils.CallbackJobDoneSub = "JobDone"
HttpUtils.PostString("Job1", b4a, "req=status")
End Sub

Sub JobDone (Job As String)
Dim s As String
If HttpUtils.IsSuccess(b4a) Then
Log(HttpUtils.GetString(b4a))
' s = HttpUtils.GetString(b4a)
' Msgbox("received: " & s, "")
' Else
' Msgbox("no connection " , "")
End If
End Sub


the point is: if i monitor the data arrive at the server, i miss the "req=status" part.
i see: POST /HTTP/1.1
Content-type: application/x-www-form-urlencoded
content-Length: 12
Connection: Close

about your HttpUtilsExample: it's static, only a picture at the screen, nothing more.

greetings, henk

Please try your code with this link: "http://www.b4x.com/print.php"
It will print the GET and POST variables.

I tried this and this is the result in log:

Erel, all i need is to login at the server with /req=status.
then the server answers with xml with data from sensors.

i switch of for the moment the username and password stuff so the server always respond when received /req=status command.

this is working for more then 2 years now and we now want to make a app so that members of our club can check the data mobile.

i hope you find something in the log

thank you for your patients, henk

The log seems to be completely fine. You can see that the req=status was indeed posted to the server.

POST variables:
array(1) {
  ["/req"]=>
  string(6) "status"
}
