If this is something you still want to do in your application for whatever reason, it's possible toĭecode the header values manually simply by calling json_decode and base64_decode on the JWT ![]() ![]() This is because without verifying the JWT, the header values could have been tampered with.Īny value pulled from an unverified header should be treated as if it could be any string sent in from anĪttacker. * * Source: */ JWT:: $leeway = 60 // $leeway in seconds $decoded = JWT:: decode( $jwt, new Key( $key, 'HS256')) Example encode/decode headersĭecoding the JWT headers without verifying the JWT first is NOT recommended, and is not supported by ![]() You can test the JSON POST handling with cURL. It makes sense that the JSON isn't handled via normal POST since there's really no key, per se essentially you just need the 'blob' of data as a whole, which is provided by php://input. It is recommended that this leeway should * not be bigger than a few minutes. From there you use jsondecode to turn the JSON string into a workable object/array. ** * You can add a leeway to account for when there is a clock skew times between * the signing and verifying servers. To get an associative array, you will need to cast it as such: */ $decoded_array = ( array) $decoded * NOTE: This will now be an object instead of an associative array. $decoded = JWT:: decode( $jwt, new Key( $key, 'HS256')) See * * for a list of spec-compliant algorithms. You can test the JSON POST handling with cURL./** * IMPORTANT: * You must specify supported algorithms for your application. It makes sense that the JSON isn't handled via normal $_POST since there's really no key, per se essentially you just need the "blob" of data as a whole, which is provided by php://input. From there you use json_decode to turn the JSON string into a workable object/array. $json_str = file_get_contents('php://input') įile_get_contents, which I though was only used to retrieve content from local files or traditional URLs, allows you to use the special php://input address to retrieve JSON data as a string. I had expected the data to land in $_POST but the variable was empty how the hell do I get the POST data? To get POST JSON with PHP, you use the following: Part of the authentication transaction requires Phabricator to receive a POST request that contains JSON data. Coming back to a language you haven't touched in years feels like a completely new experience you notice patterns and methods that you wouldn't have guessed of in years past. This task has thrust me back into the world of PHP, a language I haven't touched much (since version ~5.2) outside of creating WordPress themes and plugins for this blog. My recent work at Mozilla has me creating an OAuth-like authentication transaction between Bugzilla and Phabricator.
