Gateway location data for in flight geofencing

There should be no issue with CORS for a plain request from your PHP script gateway.php but it is reporting 502 bad gateway.

I see. Weird thing is that this worked before but just stopped now.

There are a number of questions about the architecture of the app but the main one would be regarding the gateway list - it doesn’t change fast enough to warrant requesting it for each access of your app - it may be you are being blocked due to too many requests. Perhaps look at grabbing the data every 6 or 12 hours, parsing it and turning it in to a static file.

Okay, that makes sense. We were talking about caching this inside our API, but someone raised concerns about whether this data isn’t copyrighted. I suppose it isn’t at least for these purposes, or do you know something else?

@descartes

If you have a repro we can see the code base, I’d be happy to look in to it further.

Sure. We dont have a public repo but there are only two files for this. This HTML and then the gateways.php file:

<?php

if($_SERVER['REQUEST_METHOD'] === 'GET') {

    $ch = curl_init();

    if($ch === false) {
        throw new Exception('failed to initialize');
    }

    curl_setopt($ch, CURLOPT_URL, 'https://www.thethingsnetwork.org/gateway-data/');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

    $response = curl_exec($ch);

    if ($response === false) {
        throw new Exception(curl_error($ch), curl_errno($ch));
    }

    echo $response;
}
?>

I hope that this format is okay.
