A directory listing server that accepts file uploads.

Project description

An HTTP server that displays a directory listing, much like Python’s default http.server module, except this one allows directory creation and file upload by the user.

This can be useful anytime you want to quickly share files a directory, for example in a classroom where the students need to obtain one or more files from the instructor and need to upload their exercise. In that case the instructor finds out their machine’s IP address, communicates the url http://ipaddress:port/ to the students, opens a command window and runs httpuploader like this:

$ python3 httpuploader.py -p port -d directory

and they now have a quick server.

Httpuploader is a single file with no dependencies outside the Python Standard Library. It is a WSGI application so that it can be imported as a module and run in any WSGI compliant server like mod_wsgi, Rocket, uWSGI, etc. just by instantiating the WSGIApp class with the top directory to serve and a boolean value telling it whether to show hidden files and directories.

The client’s browsers need Javascript activated. It won’t work in old versions of Internet Explorer though. Get the latest version or Edge.

Installing

An install is not really necessary since, being a single file, it can be just dropped anywhere convenient. However a setup.py program is provided for convenience so that it can be downloaded from PyPI.org using pip:

$ pip3 install httpuploader

It can also be installed using setup.py as follows:

$ python3 setup.py install

API

This version contains a RESTful API that can be used by other applications as a remote file manager, allowing not only to upload and download files and create directories, but to delete files and entire trees, calculate checksums, download compressed files and compressed archive directories, and copy and move on the same or different directories.

The API responds always with a JSON object with the following structure:

{
    "version": <the API version>,
    "rc": <the status code, e.g. 404>,
    "msg": <the status message, e.g. "Not found">,
    "data": <a json object containing the response of the call>
}

In the case of errors, the data field contains an object, containing a field named extra with an extended explanation of the error.

The API calls have the form /api/<version>/resource?cmd=<command>&<args...> where <version> is the API version number, can be just 1, 1.0 or 1.0.0. At this moment, it is the only version available, but version 1 will indicate the highest API version available of the 1.x.x range.

Available Commands

Directory Operations

list

List the contents of a directory. Does not need to be specified:

GET /api/1/<directory>?cmd=list
GET /api/1/<directory>

The response data field contains the following fields:

name:
Name of the directory
files:
List of file objects
directories:
List of directories
links:
List of possible operations
archive

Download a compressed archive with the contents of the directory:

GET /api/1/<directory>?cmd=archive&format=<zip|tar.gz>
mkdir

Create new directory:

POST /api/1/<directory>?cmd=mkdir

If successful, the response will be 204 No content

upload

Upload file(s) to directory:

POST /api/1/<directory>?cmd=upload

The files can be uploaded by simply sending the file in the body of the request, or sending several files in a multipart message.

If successful, the response will be 204 No content

delete

Remove the directory:

DELETE /api/1/<directory>

This command removes the entire tree without asking for confirmation. Use with caution.

If successful, the response will be 204 No content

File Operations

download

Download a file:

GET /<path>
GET /api/1/<path>
GET /api/1/<path>?cmd=download

It is not necessary to specify the command or the API/version prefix. The mime type of the file is guessed based on the name using the Python Standard Library mimetypes module.

info

Miscellaneous information about a file:

GET /api/<version>/path?cmd=info

Upon success, the response data field will contain a JSON object with the following files:

name:
The name of the file.
size:
The size in bytes, as a number.
human_size:
The size in a string, expressed in the easiest to read unit.
path:
Path from the top directory.
checksum:
The sha256 checksum.
atime:
Last access time, as a string in ISO format.
mtime:
Last modification time, as a string in ISO format.
ctime:
Creatrion time, as a string in ISO format.

Example:

GET /api/1/opt/jdk1.8.0_51/COPYRIGHT?cmd=info
{
  "rc": 200,
  "msg": "OK",
  "api_version": "1.0.0",
  "data": {
    "name": "COPYRIGHT",
    "size": 3244,
    "human_size": "3.17 KB",
    "path": "/opt/jdk1.8.0_51",
    "checksum": "89471aea3957922df21c7088d2687c4e43f5ff14e635e7d971083dde540b45e3",
    "atime": "2019-11-15T23:33:56.430384+00:00",
    "mtime": "2015-06-09T02:37:58+00:00",
    "ctime": "2015-07-20T18:17:40.394882+00:00"
  }
}
compress

Compress and download a single file:

GET /api/1/<path>?cmd=compress&format=<zip|tar.gz>
checksum

Compute, and optionally check, the SHA256 checksum of a file:

GET /api/1/<path>?cmd=checksum
GET /api/1/<path>?cmd=checksum&match=<checksum>

If no arguments are given the checksum of the file is computed and returned in the data field of the JSON response, which has the following fields:

filename:
The base filename for which the checksum was computed.
checksum:
The SHA256 digest as a lower case hexadecimal number.

If the match argument was used, it is used to compare it to the computed checksum, and the following field is returned in addition to the above:

match:
A boolean indicating whether the checksums match.

Example:

GET /api/1/opt/jdk1.8.0_51/COPYRIGHT?cmd=checksum&match=89471aea3957922df21c7088d2687c4e43f5ff14e635e7d971083dde540b45e3
{
  "rc": 200,
  "msg": "OK",
  "api_version": "1.0.0",
  "data": {
    "checksum": "89471aea3957922df21c7088d2687c4e43f5ff14e635e7d971083dde540b45e3",
    "filename": "COPYRIGHT",
    "match": true
  }
}
copy

Copy a file:

POST /api/1/<path>?cmd=copy&dest=<newfile>

If successful, the response will be 204 No content

move

Move or rename a file:

POST /api/1/<path>?cmd=move&dest=<newfile>

If successful, the response will be 204 No content
