Python's http.server extended to include a file upload page
|Python 3.8+||Yes||Tested on 3.8 through 3.12 every release.|
|Python 3.6-3.7||No||Was supported by previous versions.|
|Linux||Yes||Tested on Fedora and Ubuntu every release.|
|Windows||Yes||Occasional manual testing. Haven't noticed any obvious problems.|
|Mac||No idea||I don't have a Mac. Idk if it works or not.|
python3 -m pip install --user uploadserver
python3 -m uploadserver
Accepts the same options as http.server, plus a couple extras (documented below).
Warning: This is an upload server, and running it will allow uploads.
Now supports uploading multiple files at once! Select multiple files in the web page's file selector, or upload with cURL:
curl -X POST http://127.0.0.1:8000/upload -F 'firstname.lastname@example.org' -F 'email@example.com'
Basic Authentication (downloads and uploads)
python3 -m uploadserver --basic-auth hello:world
Now you can upload with basic authentication. For example:
curl -X POST http://127.0.0.1:8000/upload -F 'firstname.lastname@example.org' -u hello:world
Uploads without authentication will be rejected. Note that basic authentication credentials can be stolen if sent over plain HTTP, so this option is best used with HTTPS.
The server checks credentials before it handles the body of the request, so this mode of operation is not susceptible to DoS attack mentioned in the previous section.
Basic Authentication (uploads only)
python3 -m uploadserver --basic-auth-upload hello:world
The same as above, but authentication is only required for upload operations.
If both --basic-auth and --basic-auth-upload are specified, first one will be used for downloads and the second one for uploads.
The upload page supports a dark mode for showing white text on black background. If no option is specified, the color scheme is chosen from the client’s browser’s preference (which typically matches their operating system’s setting, if light or dark mode is supported by the OS). To enforce the light or dark theme, the CLI parameter
--theme can be used:
python3 -m uploadserver --theme light
python3 -m uploadserver --theme dark
Run with HTTPS and without client authentication:
# Generate self-signed server certificate openssl req -x509 -out server.pem -keyout server.pem -newkey rsa:2048 -nodes -sha256 -subj '/CN=server' # The server root should not contain the certificate, for security reasons cd server-root python3 -m uploadserver --server-certificate server.pem # Connect as a client curl -X POST https://localhost:8000/upload --insecure -F email@example.com
Run with HTTPS and with client authentication:
# Generate self-signed server certificate openssl req -x509 -out server.pem -keyout server.pem -newkey rsa:2048 -nodes -sha256 -subj '/CN=server' # Generate self-signed client certificate openssl req -x509 -out client.pem -keyout client.pem -newkey rsa:2048 -nodes -sha256 -subj '/CN=client' # Extract public key from self-signed client certificate openssl x509 -in client.pem -out client.crt # The server root should not contain the certificates, for security reasons cd server-root python3 -m uploadserver --server-certificate server.pem --client-certificate client.crt # Connect as a client curl -X POST https://localhost:8000/upload --insecure --cert client.pem -F firstname.lastname@example.org
Note: This uses a self-signed server certificate which clients such as web browser and cURL will warn about. Most browsers will allow you to proceed after adding an exception, and cURL will work if given the -k/--insecure option. Using your own certificate from a certificate authority will avoid these warnings.
Breaking Changes in 5.0.0
- Support for Python 3.6-7 dropped.
--tokenoption removed (use
Breaking Changes in 4.0.0
- By default, uploaded files which have the same name as an existing file are renamed. To restore the previous behavior of overwriting them, pass
- File uploads with no files in them are rejected with 400 Bad Request instead of 500 Internal Server Error, with a more informative error message.
- Handling of large uploads has been improved. Theoretically this should not cause any breaking changes, but filesystems are black magic and should be viewed with suspicion.
Breaking Changes in 3.0.0
serve_foreveris called directly, such as by an extension, the
themefield is now required on the arguments object. This change will not affect users who run this module unmodified.
Breaking Changes in 2.0.0
- File uploads now respect the
--directoryoption. Not doing so was a bug, and a security risk (since it could to the server root containing the server's certificate without the user realizing).
--tokenoption, if supplied, must be given a value. Not requiring a value was a bug, and a security risk (since a user could specify the token option but forget to provide a token).
- Some internal refactoring was done to support creating extensions. This does not affect command line use.
Breaking Changes in 1.0.0
- File field in upload form renamed from
files, to reflect support for multiple file upload. Scripts using cURL will need to be upadted with the new field name.
- Successful uploads now respond with 204 No Content instead of 200 OK, so that cURL will not default to printing the upload page at the terminal.

Thanks to lishoujun for sending the first pull request! (Added the token option.)
Thanks to NteRySin for several improvements including mTLS support and refactoring to support use by other modules.
Thanks to marvinruder for work on the upload progress indicator, theme option, and pre-validation of tokens before upload.
Thanks to shuangye for finding an easy way to handle large file uploads, and improved handling of filename collisions.
Thanks to abbbe for adding HTTP basic auth (has now replaced the token option).
