【PHP】【Too few arguments to function Firebase\JWT\JWT::encode()。。。。。。。】

1.安装jwt

composer require firebase/php-jwt

use Firebase\JWT\JWT;public function hello($name = 'ThinkPHP5'){$secret_key = "YOUR_SECRET_KEY";$issuer_claim = "THE_ISSUER";$audience_claim = "THE_AUDIENCE";$issuedat_claim = time(); // issued at$notbefore_claim = $issuedat_claim + 10; //not before in seconds$expire_claim = $issuedat_claim + 60; // expire time in seconds$token = array("iss" => $issuer_claim,"aud" => $audience_claim,"iat" => $issuedat_claim,"nbf" => $notbefore_claim,"exp" => $expire_claim,"data" => array("user_id" => "1","user_name" => "John Doe",));$jwt = JWT::encode($token, $secret_key);echo $jwt;// return 'hello,' . $name;}

上面的

$jwt = JWT::encode($token, $secret_key);

改为

 $jwt = JWT::encode($token, $secret_key, "HS256");

2.jwt解析（“firebase/php-jwt”: “^6.4” 的版本）

use Firebase\JWT\JWT;
use Firebase\JWT\Key;$jwt = JWT::encode($payload, $key, 'HS256');
//解析
$decoded = JWT::decode($jwt, new Key($key, 'HS256'));
