php - Laravel 给出错误 : The Response content must be a string or object implementing __toString(), "boolean"

Question

我在以下代码中收到上述错误，完全无法找出真正的原因。

        if ($validation->fails()) {
            // if it fails...
            return Redirect::to("login")->withErrors($validation)->withInput();
        } else {
            // storing user session... if it passes...
            $username =  Input::get("username");
            Session::put("username", $username);
            return Redirect::to("/");
        }

检查filters.php，确保Closure在通过验证时返回null或不返回。
