go-simple-upload-server

Simple HTTP server to save artifacts

Usage

Start Server

$ mkdir $HOME/tmp
$ ./simple_upload_server -token f9403fc5f537b4ab332d $HOME/tmp

(see "Security" section below for -token option)

Uploading

You can upload files with POST /upload. The filename is taken from the original file if available. If not, SHA1 hex digest will be used as the filename.

$ echo 'Hello, world!' > sample.txt
$ curl -Ffile=@sample.txt 'http://localhost:25478/upload?token=f9403fc5f537b4ab332d'
{"ok":true,"path":"/files/sample.txt"}

$ cat $HOME/tmp/sample.txt
hello, world!

OR

Use PUT /files/(filename). In this case, the original file name is ignored, and the name is taken from the URL.

$ curl -X PUT -Ffile=@sample.txt "http://localhost:25478/files/another_sample.txt?token=f9403fc5f537b4ab332d"
{"ok":true,"path":"/files/another_sample.txt"}

Downloading

GET /files/(filename).

$ curl 'http://localhost:25478/files/sample.txt?token=f9403fc5f537b4ab332d'
hello, world!

Existence Check

HEAD /files/(filename).

$ curl -I 'http://localhost:25478/files/foobar.txt?token=f9403fc5f537b4ab332d'

Security

There is no Basic/Digest authentication. This app implements dead simple authentication: "security token".

All requests should have token parameter (it can be passed from query strings or a form parameter). If it is completely matched with the server's token, the access is allowed; otherwise, returns 401 Unauthorized.

You can specify the server's token on startup by -token option. If you don't so, the server generates the token and writes it to STDOUT at WARN level log, like as:

$ ./simple_upload_server root
INFO[0000] starting up simple-upload-server
WARN[0000] token generated                               token=2dd30b90536d688e19f7
INFO[0000] start listening                               ip=0.0.0.0 port=25478 root=root token=2dd30b90536d688e19f7 upload_limit=5242880

NOTE: The token is generated from the random number, so it will change every time you start the server.
