phpjwt使用案例,记一次PHP使用JWT

从https://jwt.io/中找到目前github上目前star最多的jwt包&＃xff1a;

PHP-JWT

A simple library to encode and decode JSON Web Tokens (JWT) in PHP, conforming to RFC 7519.

Installation

Use composer to manage your dependencies and download PHP-JWT:

composer require firebase/php-jwt

Example

use \Firebase\JWT\JWT;

$key &＃61; "example_key";

$payload &＃61; array(

"iss" &＃61;> "http://example.org",

"aud" &＃61;> "http://example.com",

"iat" &＃61;> 1356999524,

"nbf" &＃61;> 1357000000

);

/**

* IMPORTANT:

* You must specify supported algorithms for your application. See

* https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40

* for a list of spec-compliant algorithms.

*/

$jwt &＃61; JWT::encode($payload, $key);

$decoded &＃61; JWT::decode($jwt, $key, array(&＃39;HS256&＃39;));

print_r($decoded);

/*

NOTE: This will now be an object instead of an associative array. To get

an associative array, you will need to cast it as such:

*/

$decoded_array &＃61; (array) $decoded;

/**

* You can add a leeway to account for when there is a clock skew times between

* the signing and verifying servers. It is recommended that this leeway should

* not be bigger than a few minutes.

*

* Source: http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#nbfDef

*/

JWT::$leeway &＃61; 60; // $leeway in seconds

$decoded &＃61; JWT::decode($jwt, $key, array(&＃39;HS256&＃39;));

Example with RS256 (openssl)

use \Firebase\JWT\JWT;
