canI如何生成jwt-php令牌发送和修改令牌并检查validate

我正试图使用这个库生成PHP令牌, https://github.com/lcobucci/jwt/blob/3.2/README.md ,我执行了以下代码:

$signer = new Sha256();

$token = (new Builder())->setIssuer('http://example.com') // Configures the issuer (iss claim)
                        ->setAudience('http://example.org') // Configures the audience (aud claim)
                        ->setId('4f1g23a12aa', true) // Configures the id (jti claim), replicating as a header item
                        ->setIssuedAt(time()) // Configures the time that the token was issue (iat claim)
                        ->setNotBefore(time() + 60) // Configures the time that the token can be used (nbf claim)
                        ->setExpiration(time() + 3600) // Configures the expiration time of the token (exp claim)
                        ->set('uid', 1) // Configures a new claim, called "uid"
                        ->sign($signer, 'testing') // creates a signature using "testing" as key
                        ->getToken(); // Retrieves the generated token

如何检查此标志是否随附请求:- >sign($signer, 'testing')

var_dump($token->verify($signer, 'testing 1')); // false, because the key is different
var_dump($token->verify($signer, 'testing')); // true, because the key is the same

此函数用于检查签名是否正确,但是,我需要使用来自请求的签名检查令牌。
