2015. June 28.
|
||||
|
||||
Version: 2.2.1.00b <== If the last 2 numbers are equal, this version is untested!
|
||||
|
||||
Usage:
|
||||
|
||||
- Basic
|
||||
|
||||
$filtr = new filtrLogin( [ CUSTOM API URL / NULL ] );
|
||||
|
||||
$filtr->setAppid( [ APPLICATION IDENTIFIER ] );
|
||||
$filtr->setApptoken( [ APPLICATION TOKEN HASH ] );
|
||||
|
||||
$filtr->setToken( [ USER'S TOKEN GENERATED BY FILTR. APL.REDIRECT ] );
|
||||
|
||||
- Advanced
|
||||
$filtr->DataStorage( [ WAT TO DO (read, write, erase) ], [ KEY (only for writing) ], [ VALUE (only for writing) ]);
|
||||
$filtr->cache = '/tmp/[ YOUR PROJECTS CODENAME ]/filtrd/';
|
||||
|
||||
Comments:
|
||||
The Filtr. API has a geniune and valid SSL certificate, but it slows down the process.
|
||||
Use it only if your connection is not trusted!
|
||||
We're logging EVERY requests, so you will be able to monitor every access and you will be able to limit the APP's access by IP.
|
||||
|
||||
Public UNAME/PASSWD authentication NEVER GONNA HAPPEN!
|
||||
|
||||
The specified cache must end with '/'. Automatic detection just slows down the process and generates unnecessary load.
|
||||
|
||||
That's it! Have fun!
|
||||
Don't forget to go out and become black. This is important! And cool! You'll be less awesome, but eh.
|
||||
|
||||
Just do it! Tomorrow.
