  • JSON
  • HTML
  • Text

Demo

See the real world example at uguu.se.

Requirements

Original development environment is Nginx + PHP5.3 + SQLite, but is confirmed to work with Apache 2.4 and newer PHP versions like PHP7.3 and PHP8.0

Node is used to compile Uguu.

Install

Detailed installation and configuration can be found at Uguu Documentation.

If you don't need a detailed one just follow the instructions below.

Compiling

First you must get a copy of the uguu code. To do so, clone this git repo.

git clone https://github.com/nokonoko/uguu

Run the following commands to do so, please configure dist.json before you compile.

cd uguu/
make
make install

OR

make install DESTDIR=/desired/path/for/site

After this, the uguu site is now compressed and set up inside dist/, or, if specified, DESTDIR.

Configuring

Front-end related settings, such as the name of the site, and maximum allowable file size, are found in dist.json. Changes made here will only take effect after rebuilding the site pages. This may be done by running make from the root of the site directory.

Back-end related settings, such as database configuration, and path for uploaded files, are found in includes/settings.inc.php. Changes made here take effect immediately. Change the following settings:

define('UGUU_DB_CONN', 'sqlite:/path/to/db/uguu.sq3');
define('UGUU_FILES_ROOT', '/path/to/file/');
define('UGUU_URL', 'https://subdomainforyourfiles.your.site');

If you intend to allow uploading files larger than 2 MB, you may also need to increase POST size limits in php.ini and webserver configuration. For PHP, modify upload_max_filesize and post_max_size values. The configuration option for nginx webserver is client_max_body_size.

Edit checkdb.sh and checkfiles.sh to the proper paths:

sqlite3 /path/to/db/uguu.sq3 "DELETE FROM files WHERE date <= strftime('%s', datetime('now', '-1 day'));"

find /path/to/files/ -mmin +1440 -exec rm -f {} \;

Then add them to your crontab:

0,30 * * * * bash /path/to/checkfiles.sh
0,30 * * * * bash /path/to/checkdb.sh

These scripts check if DB entries and files are older then 24 hours and if they are deletes them.

MIME/EXT Blocking

Blocking certain filetypes from being uploaded can be changed by editing the following settings in includes/settings.inc.php:

define('CONFIG_BLOCKED_EXTENSIONS', serialize(['exe', 'scr', 'com', 'vbs', 'bat', 'cmd', 'htm', 'html', 'jar', 'msi', 'apk', 'phtml', 'svg']));
define('CONFIG_BLOCKED_MIME', serialize(['application/msword', 'text/html', 'application/x-dosexec', 'application/java', 'application/java-archive', 'application/x-executable', 'application/x-mach-binary', 'image/svg+xml']));

By default the most common malicious filetypes are blocked.

IP logging

This is turned off by default, but you can enable it by changing:

define('LOG_IP', 'false');

Anti dupe

This is turned off by default, if a user uploads a file already uploaded the link to the already existing file will be returned instead.

define('ANTI_DUPE', 'false');

Using SQLite as DB engine

We need to create the SQLite database before it may be used by uguu. Fortunately, this is incredibly simple.

First create a directory for the database, e.g. mkdir /var/db/uguu.
Then, create a new SQLite database from the schema, e.g. sqlite3 /var/db/uguu/uguu.sq3 -init /home/uguu/sqlite_schema.sql. Then, finally, ensure the permissions are correct, e.g.

chown www-data:www-data /var/db/uguu
chmod 0750 /var/db/uguu
chmod 0640 /var/db/uguu/uguu.sq3

Finally, edit includes/settings.inc.php to indicate this is the database engine you would like to use. Make the changes outlined below

define('UGUU_DB_CONN', '[stuff]'); ---> define('UGUU_DB_CONN', 'sqlite:/var/db/uguu/uguu.sq3');
define('UGUU_DB_USER', '[stuff]'); ---> define('UGUU_DB_USER', null);
define('UGUU_DB_PASS', '[stuff]'); ---> define('UGUU_DB_PASS', null);

NOTE: The directory where the SQLite database is stored, must be writable by the web server user

API

To upload using curl or make a tool you can post using:

curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php (JSON Response)

curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php?output=text (Text Response)

curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php?output=csv (CSV Response)

curl -i -F files[]=@yourfile.jpeg https://uguu.se/upload.php?output=html (HTML Response)
