How to Force Fully Download Txt File on Link

How to save a text as .txt file via a downloadable link?

I reckon I have found a solution to your problem. Though I can't be entirely sure, it has two causes. The first one lies in the href attribute of the download link. The problem here is the " (double quotes) in the to_save variables data. The html, for what I could test with the by you provided data, renders it as follows:

<a href="data:text/plain;charset=UTF-8,b"UNA:+.? 'UNB+UNOC:3+9978715000006:14+9978715000006:14+200529:1139+50582307060_WP?+_200101_200201++TL'UNH+1+MSCONS:D:04B:UN:2.3'BGM+7+50582307060_WP?+_200101_200201-1+9'DTM+137:202005291139:203'RFF+Z13:13008'NAD+MS+9978715000006::9'CTA+IC+:Michael Jordan'COM+m.jordan@energycortex.com:EM'NAD+MR+9978715000006::9'"" download=filename.txt>Download File</a>

As you can see the value of the href attribute isn't all in the blue color (here in the stackoverflow code container above). That is because of the " that interrupt the string, it closes the earlier opened " after href=". In order to prevent this behaviour, you should replace the " in to_save with ". To the user this will look the same as " but the browser will treat it like a normal string.

You should add the following line of code to your python script to make that happen

to_save = abc.serialize().encode("ascii", "ignore")
#add this line:
to_save = to_save.replace('"','"')

Next the download attribute doesn't have any double quotes around it's value. It should, formally, look like this: download="filename.txt". Then again, for safety replace any possible"with"`.

The full python code should now look like this:

reference = 50582307060_WP+_200101_200201
reference = reference.replace('"','"')

to_save = abc.serialize().encode("ascii", "ignore")
to_save = to_save.replace('"','"')

href = f'<a href="data:text/plain;charset=UTF-8,{to_save}" download="{reference}.txt">Download File</a> (right-click and save as {reference}.txt)'
st.markdown(href, unsafe_allow_html=True)

Hope this helps! If not, please comment.

Force download of 'data:text/plain' URL

As of now, it has been made possible to use <a download> in Chrome. Using dispatchEvent, you can download any string as file (even with a custom filename) whenever you want. Here's a utility function to use it:

var downloadFile = function(filename, content) {
  var blob = new Blob([content]);
  var evt = document.createEvent("HTMLEvents");
  evt.initEvent("click");
  $("<a>", {
    download: filename,
    href: webkitURL.createObjectURL(blob)
  }).get(0).dispatchEvent(evt);
};

Usage:

downloadFile("foo.txt", "bar");

It uses jQuery and the webkit prefix, but both can be avoided.

How to force a Download File prompt instead of displaying it in-browser with HTML?

This is something that you cannot absolutely control with HTML itself.

If the user is having a browser with PDF reading capabilities (or a plugin) and the corresponding settings to open PDF files in-browser, the PDF will open like that.

The PDF opens in a new tab simple because of your target="_blank", which has nothing to do with a download prompt.

If you are using HTML5 you can use the download attribute:

<a href="sample.pdf" download="sample.pdf">Download</a>

If you have a back-end service which you can control or you feel like fiddling with your Web Server, you can always look for setting the right Content-Disposition. See this SO question for some nice discussion on Content-Disposition.

You can do it like this, it won't redirect you and also works good for larger files.

In your controller "Controller.php"

function downloadFile(){
        $yourFile = "Sample-CSV-Format.txt";
        $file = @fopen($yourFile, "rb");

        header('Content-Description: File Transfer');
        header('Content-Type: application/octet-stream');
        header('Content-Disposition: attachment; filename=TheNameYouWant.txt');
        header('Expires: 0');
        header('Cache-Control: must-revalidate');
        header('Pragma: public');
        header('Content-Length: ' . filesize($yourFile));
        while (!feof($file)) {
            print(@fread($file, 1024 * 8));
            ob_flush();
            flush();
        }
}

In your view "view.php"

<a href="<?=base_url("Controller/downloadFile")?>">Download</a>
