Why is it that after the teacher typed this code to set the user session value, there was no response when I clicked the login button and I couldn’t log in?

Question

  Session::set('user_id',$user->id);

  Session::set('user_info',$user->getData());

Answer 1

tp5.1 changed the reference path to: use think\Facade\Session;

Answer 2

Print it first to see if you can output the data you submitted and see if the data is correct

Answer 3

user.php

....

use think\Request;

use app\index\model\User as UserModel;

use think\Session;

....

public function checkLogin(Request $request)

{

//Initial return parameters

$status = 0;

$result = '';

$data = $request -> param();

//Create validation rules

                  $rule = [                                                                                                                                                               ’ ’ ’ s ’ s ’ s                     ’ ’ ’ s ’ ’ s ’ ’ s ‐ ‐ ‐ ‐ ‐ ‐ to 'name|Username' => 'require',

##                      ## 'Veritfy | Verification Code' = & GT; 'Require | CAPTCHA',

##;

## // ## $ msg = [

# 'name' = & gt; ['Require' = & gt; 'Username cannot be empty, please check'],

'password' = & gt; [[[[[[[[ 'require'=>'The password cannot be empty, please check'],

'veritfy' =>['require'=>'The verification code cannot be empty, please check',

                         'captcha'=>'Verification code error, please check'

                                                                                                                            $result = $this -> validate($data,$rule,$msg);

##                                                                                                                                                                                                                                                ($ Result === True)

# {

# 'Password' = & GT; md5 ($ data ['password']

##] [[

$ User = Usermodel :: get ($ map);

## counter ($ user == null) {

$ result = 'No found! ';

      }else{

            $status = 1;

              $result = 'Verification passed, click [OK] to enter!';

            //设置用户的Session值

            //Session::set('user_id',$user->id);//用户ID

          //  Session::set('user_info',$user->getData());//获取用户所有信息

          Session::set('user_id,$user[id]');

          Session::set('user_info.name',$user['name']);

        

          }

        }

        return ['status'=>$status,'message'=>$result,'data'=>$data];
