Just insert your domain info into the example code in the help file...

Code: Select all

Procedure HttpGetEvent(Success, Result$, UserData)
  If Success
    Debug Result$
    Else
    Debug "HTTPRequest(): Error"
  EndIf
EndProcedure

Global url.s="https://sepa-convertir.eu/spider/toto.xml"
HTTPRequest(#PB_HTTP_Get, url, "", @HttpGetEvent())
And remember, your Spider Basic app must also run from the same Domain or it won't work for security reasons.

See... viewtopic.php?f=6&t=2029

What with the domain if the code is runs as an app on an android phone ?

I created an app an run it both as

1) web-app in chrome browser on android phone
2) android app on android phone

in case 1) the 'Exportfile' tells me it created a file witch I find in the download section.
in case 2) the 'Exportfile' tells me it created a file witch I can't find anywhere (it is not created at all)

Code: Select all

...
download_file_name.s = "TEST.PDF"
mainURL.s = "https://www.some_domain.com/"
...
ReadFile(1, mainURL + download_file_name, @FileLoadedCallback())
...
...
Procedure FileLoadedCallback(Status, Filename$, File, SizeRead)
  Select status
    Case #PB_Status_Loaded
      If CreateFile(1,download_file_name,@filesavedCallback(),#PB_UTF8)
        While Eof(File) = #False
          WriteByte(1,ReadByte(File))            
        Wend
        CloseFile(File)
        ExportFile(1,"application/pdf")
        CloseFile(1)
        MessageRequester("loading (" + download_file_name + ") suceeded" + #CRLF$ + "Creating (" + download_file_name + ") on disk succeeded",#PB_MessageRequester_Ok)
      Else
        MessageRequester("loading (" + download_file_name + ") suceeded" + #CRLF$ + "Creating (" + download_file_name + ") on disk failed",#PB_MessageRequester_Ok)
      EndIf  
    Case #PB_Status_Error
        MessageRequester("loading (" + download_file_name + ") has failed",#PB_MessageRequester_Ok)
  EndSelect 
EndProcedure

I don't think this works because the requested data is returned as a string in your HttpGetEvent procedure and saving a PDF as a string is not going to work. Williams code will work because it allows the saving as Bytes. Here is his code as a complete working example...

Code: Select all

Global download_file_name.s = "qrfacture.pdf"
mainURL.s = "https://sepa-convertir.eu/spider/"

Procedure filesavedCallback(Status, Filename$, File, SizeRead)
  Select Status
    Case #PB_Status_Saved
      Debug "File correctly saved"
      
    Case #PB_Status_Error
      Debug "File saving has failed"
  EndSelect
EndProcedure

Procedure FileLoadedCallback(Status, Filename$, File, SizeRead)
  Select status
    Case #PB_Status_Loaded
      hFile=CreateFile(#PB_Any,download_file_name,@filesavedCallback(),#PB_UTF8|#PB_LocalFile)
      If hFile
        While Eof(File) = #False
          WriteByte(hFile,ReadByte(File))            
        Wend
        CloseFile(File)
        ExportFile(hFile,"application/pdf",#PB_LocalFile)
        CloseFile(hFile)
        Debug "Load/Create succeeded"
        Else
        Debug "Load/Create failed"
      EndIf  
      
    Case #PB_Status_Error
      MessageRequester("loading (" + download_file_name + ") has failed",#PB_MessageRequester_Ok)
  EndSelect 
EndProcedure

ReadFile(0, mainURL + download_file_name, @FileLoadedCallback())
Personally I would use something like this which allows the browser to do the work and gives the user the option to save the PDF or view it in the browser.

Code: Select all

url.s="https://sepa-convertir.eu/spider/qrfacture.pdf"
! downloads.open(v_url);


@William Van Hoecke

Sorry William, due to the extreme lack of features and functionality in SpiderBasic for Mobile devices, I use a different platform for developing Mobile Apps so I have no idea where it might put the files.
The APK created by SpiderBasic looks like a webpage in disguise so maybe the file gets saved in the browser folder, or maybe in the APK's installation folder, or maybe it doesn't save at all since ExportFile doesn't return anything to let you know if it was success or fail.
