ThinkPHP6 使用JwtToken

1.安装JwtToken

composer require firebase/php-jwt

2.新建PHP类文件

这里新建了Token.php类文件，用于token的签发和验证

<?php

namespace app\home;

use Firebase\JWT\JWT;
use Firebase\JWT\Key;

class Token
{
    protected $salt;
    protected $keyId;

    public function __construct()
    {
        $this->salt = md5("1585364631");
    }

    function getToken($uid): string
    {
        $currentTime = time();
        return JWT::encode([
            "iss" => 'dao',
            "aud" => '',
            "iat" => $currentTime,
            "nbf" => $currentTime,
            "exp" => $currentTime + 3600 * 24,
            "data" => [
                'uid' => $uid,
            ]
        ], $this->salt, "HS256");
    }

    public function checkToken($token): array
    {
        $res = array("code"=>201);
        try {
            JWT::$leeway = 60;
            $decoded = JWT::decode($token, new Key($this->salt, 'HS256'));
            return [
                "code"=>200,
                "data"=>((array)$decoded)['data']
            ];
        } catch(\Firebase\JWT\SignatureInvalidException $e) {
            $res['msg']="签名不正确";
        }catch(\Firebase\JWT\BeforeValidException|\Firebase\JWT\ExpiredException $e) {
            $res['msg']="token失效";
        } catch(\Exception $e) {
            $res['msg']="token无效";
        }
        return $res;
    }
}

3.新建中间件文件

需要登入使用的进行校验

<?php

namespace app\home\middleware;

use app\home\Token;
use Closure;
use think\Request;
use think\Response;
use think\response\Redirect;

class UserToken
{
    /**
     * 处理请求
     *
     * @param Request $request
     * @param Closure $next
     * @return Response|Redirect
     */
    public function handle(Request $request, Closure $next)
    {
        $token = $request->header('jwtToken',"");
        $res = (new Token())->checkToken($token);
        if ($res['code'] != 200 ){
            return json($res);
        }

        $request->uid = $res['data']->uid;
        return $next($request);
    }
}
