B4X:

Sub JobDone (Job As HttpJob)
  Log("JobName = " & Job.JobName & ", Success = " & Job.Success)
  Dim aan As String
  Dim lampstatus As String = "true"
  aan = "{""on"": " & lampstatus & "}"
  If Job.Success = True Then
      ToastMessageShow(Job.GetString,True)
Job.PostString("http://192.168.1.5/api/newdeveloper/lights/2/state", aan )
  Else
      Log("Error: " & Job.ErrorMessage)
      ToastMessageShow("Error: " & Job.ErrorMessage, True)
  End If
  Job.Release

  End Sub
 
Sub Button1_Click
      job1.Initialize("Job1", Me)
  job1.Download("http://192.168.1.5/api/newdeveloper/lights/2/state")

The compiled HttpUtils2 library only provides methods for GET or POST requests.

PUT request is very similar to a POST request.

You have two options:
1. Remove HttpUtils2 and use HttpClient directly.
2. Remove the reference to HttpUtils2 library. Add HttpUtils2 two code modules (and the libraries it depends on).
Modify HttpJob.PostBytes to:

B4X:

Public Sub PostBytes(Link As String, Data() As Byte)
   req.InitializePut2(Link, Data) '<-- InitializePut2 instead of InitializePost2
   CallSubDelayed2(HttpUtils2Service, "SubmitJob", Me)
End Sub

1. didn't work
can you exoplane option 2 in more detail?
and what can I do with
InitializePut (URL As String, InputStream As java.io.InputStream, Length As Int)

Erel · Oct 23, 2013

You should use InitializePut2 not InitializePut. Which of the steps is not clear?

My program is broken

It will do this

B4X:

Dim lampstatus As String = "true"
aan = "{""on"": " & lampstatus & "}"
Dim URL As String
URL = "http://192.168.1.5/api/newdeveloper/lights/2/state"

This is what I want to sent with (aan) a put methode

what must i use now?
HttpJob or HttpRequest or..

Can you write a little code to understand?

Let me know!

eps · Oct 24, 2013

Erel is suggesting that either you use HTTPClient, directly, which is a bit more fiddly OR you remove the lib reference to HTTPUtils2, place the two modules directly in your code and edit the PostBytes code as per his recommendation.

The choice is yours, one or the other.

Hi I am beginner with basic4Android
I came from appinventor

This is how the code look like in appinventor and now I want to made it in B4A

Erel · Nov 1, 2013

Please start a new thread for this question. I recommend you to go over the beginner's guide: http://www.b4x.com/android/documentation.html

appie21 · Nov 1, 2013

But it is my same question as in the first post?

Can some one make a sample use put methode with this information

B4X:

Dim lampstatus As String = "true"
aan = "{""on"": " & lampstatus & "}"
Dim URL As String
URL = "http://192.168.1.5/api/newdeveloper/lights/2/state"

appie21 · Nov 1, 2013

But i do not really understand

B4X:

Sub Globals
Dim req As HttpRequest

    Dim aan As String
    Dim lampstatus As String = "true"
    Dim URL As String
    aan = "{""on"": ""true""}"
    URL    = "http://192.168.1.5/api/newdeveloper/lights/2/state"
   
End Sub

Sub Activity_Create(FirstTime As Boolean)

    End Sub
Public Sub PostBytes(Link As String, Data() As Byte)
  req.InitializePut2(URL, aan) '<-- InitializePut2 instead of InitializePost2
  CallSubDelayed2(HttpUtils2Service, "SubmitJob", Me)
End Sub

eps · Nov 1, 2013

If you want to send me some code, I can trial this for you.

appie21 · Nov 1, 2013

Hi
That will be great the code is also as above!

appie21 · Nov 4, 2013

B4X:

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Dim req As HttpRequest
    Dim Button1 As Button
    Dim aan As String
    Dim url As String
    aan = "{""on"": ""true""}"
    url   = "http://192.168.1.41/api/newdeveloper/lights/2/state"
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Layout1")



End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub
Public Sub PutString(Link As String, Text As String)
    PutBytes(Link, Text.GetBytes("UTF8"))
End Sub

Public Sub PutBytes(Link As String, Data() As Byte)

    req.InitializePut2(Link, Data)
    CallSubDelayed2(HttpUtils2Service, "SubmitJob", Me)
End Sub


Sub Button1_Click
    PutBytes(url, aan.GetBytes("UTF8"))
End Sub

You should check the logs and post the error message.

The two code modules are missing from the zip file.

appie21 · Nov 4, 2013

What you mean? by code modules

eps · Nov 4, 2013

The SubmitJob, the code for that isn't included... I guess that's your Service for the lights / switches you wish to control.

The error indicates that you are sending info. that it isn't expecting or not in the right format.
java.lang.Exception: Sub submitjob signature does not match expected signature.
