  • 权限验证

        // api白名单
    public static String[] allowPath = new String[] {"user/login", "user/register"};

    public static void tokenAuthMiddleware(Request req, Response res) {
        if (Arrays.asList(TokenAuth.allowPath).contains(req.splat()[0])) return;

        // 得到header或query上的email和token
        var email = getArg(req, "email");
        var token = getArg(req, "token");

        // 若header和query都不存在email和token，直接401
        if (token == null || email == null) halt(401, "未经授权的请求");
        var redis = utils.Redis.getJedis();
        // 通过email拿到redis用户信息
