Posting Data to your own Web Server
(Advanced Feature)
The device can periodically transmit data to a local or remote web site. This is done by sending an HTTP POST message
to a given URL (website address, such as http://www.your-server.com/). This message can be interpreted by server-side
scripts, such as those written in PHP, ASP, JSP, CGI, and similar technologies. Such scripts could log the information,
upload it to a database, control some other device with the information, and so on.
The format of the HTTP POST is customizable using a template. By default, the device ships with a template that posts in
JSON format, but by customizing the template, you could post in any other format, such as XML, CSV, or proprietary
formats specific to your company or organization. Details for customizing your template are provided in
While the details of server-side scripting are beyond the scope of this document, a sample script written in the PHP
scripting language is provided below for reference. The script reads the data from the HTTP POST and appends that data
to the end of the log file called
“
posts.log
”
.
<html>
<body>
<?php
// Place the contents of the HTTP POST into a variable
$postdata =
file_get_contents
(
"php://input"
);
// Save the data to a log file
$handle =
fopen
(
"posts.log"
,
"a"
);
fwrite
($handle, $postdata);
fclose
($handle);
?>
</body>
</html>

—
Trailing Slashes:

/
. For
instance, http://www.your-server.com/data
/
