ready to develop Mini Program, first test the background API, project to develop using Laravl+jwt+dingo. JWT wants to find such a middleware on the Internet during painless refresh token, testing

    public function handle($request, Closure $next)
    {
        //  token 
        $this->checkForToken($request);

       //  try  token  TokenExpiredException  
        try {
            // 
            if ($this->auth->parseToken()->authenticate()) {
                return $next($request);
            }
            throw new UnauthorizedHttpException("jwt-auth", "");
        } catch (TokenExpiredException $exception) {
          //  token  TokenExpiredException  token 
            try {
                //  token
                $token = $this->auth->refresh();
               // 
                Auth::guard("api")->onceUsingId($this->auth->manager()->getPayloadFactory()->buildClaimsCollection()->toPlainArray()["sub"]);
            } catch (JWTException $exception) {
               //  refresh 
                throw new UnauthorizedHttpException("jwt-auth", $exception->getMessage());
            }
        }
        
        //  token
        return $this->setAuthenticationHeader($next($request), $token);
    }

after testing the interface in postman, there is no way to add authorization
$this- > setAuthenticationHeader in response to header after each request. The source code is:

    protected function setAuthenticationHeader($response, $token = null)
    {
        $token = $token ?: $this->auth->refresh();
        $response->headers->set("Authorization", "Bearer ".$token);

        return $response;
    }

$response- > headers- > set ("Authorization"," Bearer". $token); cannot be added here. Why?
finally switch to this way:

        return $next($request)->withHeaders([
                "Authorization"=> "Bearer ".$token,
            ]);

there should be no problem with the method that comes with dingo. Is there something wrong with me?
