Triops is a simple web server for debugging IOT hardware with minimal setup.
It is written in PHP and can be used on shared hosts (though its streaming section requires access to redis).
You can see this site.php
Triops contains a few "boiler plate" pages for checking connectivity.
Primitive checks allow a client to use http to get text (non HTML) data which can consoled out (eg at REPL or serial debug).
These are:
- time check - any call to this page returns plain-text server time w/o any HTML formatting
- sum - any call to this page allows the client to submit get params which will be numerically summed. userful for basic connectivity formatting checks
- ip - see client reported ip at server
- rawpost - this allows a client/device to post any string data to the page. the raw-post-read page will read the last posted data
- rawget - this allows a client/device to post any set of vars to the page. the raw-get-read page will read the last get encoded data
The following pages allow a device to post data. However the device must be in the registry. To do this go to the admin page and add the device
- devpost - a page which allows a registered device to post data
- devread - a page which allows a regiersred device to read data (if avail)
- devregister - a page which allows a device to attempt to register. Only if it is "accepted" (see admin) will that device be able to make user of devpost or devread
Assunes apache2 or LAMP/WAMP installed.
