Both functions only works with UTF-8 encoded string data. These functions are jsonencode () and jsondecode (), respectively. When a call to JWT::decode is invalid, it will throw one of the following exceptions: PHP has built-in functions to encode and decode JSON data. $jwt = 'eyJhbGci.' // Some JWT signed by a key from the $jwkUri above $decoded = JWT:: decode( $jwt, $keySet) Miscellaneous Exception Handling Null, // $expiresAfter int seconds to set the JWKS to expire true // $rateLimit true to enable rate limit of 10 RPS on lookup of invalid keys Create a cache item pool (can be any PSR-6 compatible cache item pool) $cacheItemPool = Phpfastcache\ CacheManager:: getInstance( 'files') The jsondecode () function has a second parameter, and when set to true, JSON objects are decoded into associative arrays. ![]() The jsondecode () function returns an object by default. Create an HTTP request factory (can be any PSR-17 compatible HTTP request factory) $httpFactory = new GuzzleHttp\ Psr\ HttpFactory() The jsondecode () function is used to decode a JSON object into a PHP object or an associative array. Create an HTTP client (can be any PSR-7 compatible HTTP client) $httpClient = new GuzzleHttp\ Client() The URI for the JWKS you wish to cache the results from $jwksUri = '' $decoded = JWT:: decode( $jwt, new Key( $publicKey, 'RS256')) Įcho " Decode:\n". $jwt = JWT:: encode( $payload, $privateKey, 'RS256') Įcho " Encode:\n". 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 It also works as to view JSON in hierarchy form. What can you do with jsondecode It helps to online decode JSON data. 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. JSON Decode Online is easy to use tool to decode JSON data, view JSON data in hierarchy and show as jsondecode php. * * 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 ![]() It is recommended that this leeway should * not be bigger than a few minutes. ** * 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. ** * IMPORTANT: * You must specify supported algorithms for your application.
