HTTP Request Node: Read filename from content-disposition header when downloading files

HTTP Request Get file link gives me an incomplete binary file. Only Mime Type: image/jpeg is visible. At the same time, the link in the browser downloads the file.
Please help me, how in this situation can I can get a complete binary file - with extension and name?
Thank you.

Information on your n8n setup

  • **n8n version:**0.174.0
  • **Running n8n via [Docker, npm,, desktop app]:**Docker

I checked with the service where the file is stored - the link is redirected. The link is
In the node put all the options I could, but the binary file still does not contain the name and extension of the file.
Please help me how to get binary file with name and extension.

How can I get an output like the one on the test file?:

Hey @asuhan, I am not aware of a way to set the filename from the content-disposition header in your screenshot on the fly unfortunately, so I have converted this into a feature request for the time being.

As a workaround, you could manually rename the file like so if needed:

This example code is built upon this snippet provided by a helpful Stack Overflow user and further uses getBinaryData() and setBinaryData(binaryData) to manipulate the binary data received by the HTTP Request node.

Hope this helps!

You are most welcome, glad to hear this helps!

can you please send a copy of this code you are using ?

Hi @MotazHakim, it should be visible in the workflow above when you open the Function Item node named Rename.

However, seeing n8n has changed a bit since this was originally posted, I’ve also built a new workflow using the latest node versions, including the current Code node (and a new image URL):

This is the code from the Code node on its own (make sure to set Mode to “Run Once for Each Item” for this to work):

// From
function getFileName(disposition) {
    const utf8FilenameRegex = /filename\*=UTF-8''([\w%\-\.]+)(?:; ?|$)/i;
    const asciiFilenameRegex = /^filename=(["']?)(.*?[^\\])\1(?:; ?|$)/i;

    let fileName = null;
    if (utf8FilenameRegex.test(disposition)) {
      fileName = decodeURIComponent(utf8FilenameRegex.exec(disposition)[1]);
    } else {
      // prevent ReDos attacks by anchoring the ascii regex to string start and
      //  slicing off everything before 'filename='
      const filenameStart = disposition.toLowerCase().indexOf('filename=');
      if (filenameStart >= 0) {
        const partialDisposition = disposition.slice(filenameStart);
        const matches = asciiFilenameRegex.exec(partialDisposition );
        if (matches != null && matches[2]) {
          fileName = matches[2];
    return fileName;

$ = getFileName($json.headers['content-disposition']);

return $input.item;

Hope this helps!
