意外值异常

Question

我正在整理我的api时邮递员出现错误。它显示邮递员中的苗条应用程序错误。错误类型：UnexpectedValueException

消息：错误的段数

文件：C：\ Users \ tahmeed \ Documents \ app-timber-api2 \ vendor \ firebase \ php-jwt \ src \ JWT.php

行：78

我需要修改令牌或JWT.php吗？

JWT.php中的decode.php

您应在解码方法中使用第三个参数来解决未捕获的UnexpectedValueException：不允许使用算法

这是下面的代码

<?php;
require('jwt/vendor/autoload.php');
use \Firebase\JWT\JWT;




function generate_token($uid){

    $key = "thiismykey";
    $jwt = JWT::encode($uid, $key);
    echo "JWT Toke = ".$jwt."<br>";

    $decoded = JWT::decode($jwt, $key, array('HS256'));

    echo "After Encode = ".$decoded;

}


//call the funtion
generate_token("santosh");



?>

输出-

JWT Toke = eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.InNhbnRvc​​2gi.ZUyzpLH0FLB9VdRPS2CaQAqM_wKHjXP80moIzL-8u2o在编码= santosh之后
