B4J Question Upload jpg/mp4 to Websocket fileupload

Nizze · Sep 18, 2019

Hi

I use Erels example for B4J for http upload
I use this code for uploading a jpg that i found in the forum here to upload to server with a PHP script.
It works on a server with apache

No i want to have it running with B4J

this is the code from the android client:

B4X:

Sub PhotoUpload(filname As String)
    Log("PhotoUpload " & filname)

    PostPath = "http://www.xxxxx.se:81/websocket_with_fileupload/index.html"
    Dim j As HttpJob
    Dim img As String = filname '"1.jpg"
    j.Initialize("", Me)
    Dim mp As MultipartFileData
    mp.Initialize
    mp.Dir = rp.GetSafeDirDefaultExternal("")
    mp.FileName = img
    mp.KeyName = "file"
    mp.ContentType = "image/jpg"
    j.PostMultipart(PostPath, Null, Array(mp))
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        Log("- - - - - - - - - - - - - ")
        Log(j.GetString)
        If img = j.GetString Then
            ToastMessageShow("Kort upladdat.", False)
        Else
            ToastMessageShow("Fel vid uppladdning", False)
        End If
    End If
    j.Release
    
End Sub

and the log from the server :

Start success: true
(Rect)(0, 0, 3264, 2448)
Picture taken: (Bitmap): 1920 x 1080, scale = 1,00
Photo dir /storage/emulated/0/Android/data/nn.test/files
Doning 2.jpg

<script>
$( document ).ready(function() {
b4j_connect("/websocket_with_fileupload/ws");
});
</script>

Don't use WebSockets for this. Use a regular handler.
The WebSocket handler works with browsers not simple clients.

There is also no reason to use multipart requests which add a lot of overhead.

Check this a bit old example: https://www.b4x.com/android/forum/t...r-b4j-server-over-the-internet.37201/#content
