token的生成

composer require lcobucci/jwt

use Lcobucci\JWT\Builder;

$token = (new Builder())->setIssuer('http://example.com') //配置issuer（iss声明）

                        ->setAudience('http://example.org') //配置听众（aud声明）

                        ->setId('4f1g23a12aa', true) 

                        ->setIssuedAt(time()) // Configures the time that the token was issue (iat claim)
                        ->setNotBefore(time() + 60) // Configures the time that the token can be used (nbf claim)
                        ->setExpiration(time() + 3600) // Configures the expiration time of the token (exp claim)
                        ->set('uid', 1) // Configures a new claim, called "uid"
                        ->getToken(); // Retrieves the generated token


$token->getHeaders(); // Retrieves the token headers
$token->getClaims(); // Retrieves the token claims

echo $token->getHeader('jti'); // will print "4f1g23a12aa"
echo $token->getClaim('iss'); // will print "http://example.com"
echo $token->getClaim('uid'); // will print "1"
echo $token; // The string representation of the object is a JWT string (pretty easy, right?)

use Lcobucci\JWT\Parser;

$token = (new Parser())->parse((string) $token); // Parses from a string
$token->getHeaders(); // Retrieves the token header
$token->getClaims(); // Retrieves the token claims
