Laravel Scavenger
https://ift.tt/3deeHKO
The most integrated web scraper package for Laravel.
Scavenger provides the following features and more out-the-box.
Scavenger is highly configurable. These configurations remain for use the next time around.
Below is an example of a typical config file structure, with explaining comments.
<?php return [ // debug mode? 'debug' => false, // whether log file should be written 'log' => true, // How much detail is expected in output, 1 being the lowest, 3 being highest. 'verbosity' => 1, // Set the database config 'database' => [ // Scraps table 'scraps_table' => env('SCAVENGER_SCRAPS_TABLE', 'scavenger_scraps'), ], // Daemon config - used to build daemon user 'daemon' => [ // Model to use for Daemon identification and login 'model' => 'App\\User', // Model property to check for daemon ID 'id_prop' => 'email', // Daemon ID 'id' => 'daemon@scavenger.reliqarts.com', // Any additional information required to create a user: // NB. this is only used when creating a daemon user, there is no "safe" way // to change the daemon's password once he has been created.
