Android Question httpjob unable to get the filename

[ludogomez]

Hello,

I try to download files from a server (nextcloud server for example), but I don't know filename.

If I use a web browser, it retrieve the filename. But when I use b4a with httpjob, I don't have the filename.
I try getheaders, but without succes.

I join a small project.
You can try with this link : https://www.leslulus.com/nextcloud/index.php/s/stCoQ6WBTkqBXNx

Thanks
Regards

You can try with this link : https://www.leslulus.com/nextcloud/index.php/s/stCoQ6WBTkqBXNx

i´m getting this error when i open the url in a browser.

cURL error 7: Failed to connect to 192.168.210.67 port 9980: No route to host (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)

Due to the error i dont expect it to work from B4A

headers:content-disposition:[attachment; filename*=UTF-8''test.odt; filename="test.odt"]
This is a line of the headers when calling

    Dim url As String = "https://www.leslulus.com/nextcloud/index.php/s/stCoQ6WBTkqBXNx/download"
   
    Dim j As HttpJob
    j.Initialize("", Me)
    j.Download(url)
    '    j.GetRequest.SetHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0")
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        Dim resp As OkHttpResponse = j.Response
        Dim list1 As Map
        list1 = resp.GetHeaders
        For i = 0 To list1.Size - 1
            Log("headers:" & list1.GetKeyAt(i) & ":" & list1.GetValueAt(i))
        Next
           
        Dim filename As String
        filename = url.SubString(url.LastIndexOf("/"))
               
        Dim su As StringUtils
        filename = su.DecodeUrl(filename,"UTF8")
        Log(filename)
               
        Dim out As OutputStream = File.OpenOutput(File.DirInternal, filename, False)
        File.Copy2(j.GetInputStream, out)
        out.Close '<------ very important
       
        Log(File.ListFiles(File.DirInternal))

this is the headerline you need to parse and extract the filename

Note that i suffixed the url with "/download" to get this result

Thanks for the response,

I try with my server and I did not see the good header, my bad.

But for my app, I'll try another server but :

• it's a microsoft tecnhology (ASPNET)
• it's not my server
• I must connect with a login/password

I can't reproduce easily this behaviour :

this the headers:
