Hi Lars,

You need to return a sequence of two items: (restxq:response,thedata) 

I do something like...

declare

  %rest:path("/download/{$file}")

  function page:download-file($file)

  {

   (download-response("raw",$file), file:read-binary(..))

  };

(:~ headers for download  :) 

declare function download-response($method,$filename){

<restxq:response>

    <output:serialization-parameters>

        <output:method value="{$method}"/>

    </output:serialization-parameters>

   <http:response>

       <http:header name="Content-Disposition" value='attachment;filename="{$filename}"'/> 

    </http:response>

</restxq:response>

};

I came a little closer by making custom http:headers, but I have to confess I'm in deep water here:

declare

  %rest:path("/download/{$file}")

  function page:download-file($file)

  {

    <rest:response>

     <http:response status="200" message="OK">

   

    <http:header name="Content-Disposition" value="Attachment"/>

   <http:header name="filename" value="{$file}"/>

  </http:response>

</rest:response>

  

  };

This function do trigger a download of a file with the appropriate file name (=$file) containing the text OK. If I just could find somewhere in this code to put the contents of file, it should solve the problem.

Best,

I am using BaseX restxq for accessing a repository from a web browser. Uploading files works smoothly, but I can't see how to make a download button work.

For uploading, the recipie on the restxq help page was enough to get it to work. Is there a corresponding way for making downloading work? 

What I have tried is to let BaseX send a html-page containing:

 <form method="get" action="/download/{$file}">

              <button type="submit">Download</button>

              </form>

  

To process this form is the following restfunction

declare

  %rest:path("/download/{$file}")

  %output:method("html")

  function page:download-file($file) { ... }

Inside the curly braces, I have tried an <a href..> element and file:read-binary, but none of them with any success. BaseX complains about the <a> element, and file:read-binary outputs directly to the browser.

Any suggestions?
