Example

  dd($user);
  $token = Request::instance()->header('token');

//生成验签

          "iss" => $key,        //签发者 可以为空
          "aud" => '',          //面象的用户,可以为空
          "iat" => time(),      //签发时间
          "nbf" => time() + 3,    //在什么时候jwt开始生效  (这里表示生成100秒后才生效)
          "exp" => time() + 200, //token 过期时间
          "data" => [           //记录的userid的信息,这里是自已添加上去的,如果有其它信息,可以再添加数组的键值对
              'uid' => $uid,

Using JWKs

// Set of keys. The "keys" key is required. For example, the JSON response to
// this endpoint: https://www.gstatic.com/iap/verify/public_key-jwk
$jwks = ['keys' => []];

// JWK::parseKeySet($jwks) returns an associative array of **kid** to private
// key. Pass this as the second parameter to JWT::decode.
JWT::decode($payload, JWK::parseKeySet($jwks), $supportedAlgorithm);

Tests

Run the tests using phpunit:

$ pear install PHPUnit
$ phpunit --configuration phpunit.xml.dist

New Lines in private keys

If your private key contains \n characters, be sure to wrap it in double quotes "" and not single quotes '' in order to properly interpret the escaped characters.
