Session store not set on request

Novice laravel,session keeps reporting errors.
is configured as follows:
config/session.php

return [
    "driver" => env("SESSION_DRIVER", "file"),
    "lifetime" => 120,
    "expire_on_close" => false,
    "encrypt" => false,
    "files" => storage_path("framework/sessions"),
    "connection" => "session",
    "lottery" => [2, 100],
    "cookie" => "laravel_session",
    "path" => "/",
    "domain" => null,
    "secure" => false,
];

controller is as follows:

use Illuminate\Http\Request;

class AccountController extends Controller
{

    /**
     * 
     */
    public function login(Request $request)
    {
    $phone = Input::get("mobile");
    $pwd   = Input::get("pwd");
    $callback = Input::get("callback","");
        if (empty($phone) || empty($pwd)) {
            exit(json_encode(["code"=>-1,"msg"=>"params not null"]));
        }

        $userService = UserService::getInstance();
        $resInfo = $userService->login($phone,$pwd);
        $a = $request->session()->put("user",1111);
            $b = $request->session()->save();
        var_dump($a, $b);die;
        if ($resInfo) {
        $ret = ["code"=>0,"msg"=>"ok","data"=>$resInfo];
        }else{
            $ret = ["code"=>-1,"msg"=>"error"];
    }
    if($callback)
        exit($callback . "(".json_encode($ret).")");
    exit(json_encode($ret));
    }

the output is always Session store not set on request,. Could you tell me how to configure and operate the session of laravel5.6?
