<script>
    $('#login').click(function (){
        var account =$('.account').val();
        var password=$('.password').val();
        $.ajax({
            url:'/ajax/ajax/save',
            type:'POST',
            data:{
                account:account,

                // console.log(res)
          if (res.code==200){
              alert('登录成功');
              //将用户res里的Token存入在本地
              localStorage.setItem('token','res.data.token')
              location.href='/ajax/ajax/index';
          }
            }
        })

    })




</script>

2：控制器代码

 

 

 

<?php

namespace app\ajax\controller;

use app\ajax\model\AjaxModel;
use think\Controller;
use think\Request;
use think\Session;
use think\View;
use tools\jwt\Token;

class Ajax extends Controller
{
    /**
     * 显示资源列表
     *
     * @return \think\Response
     */
    public function index()
    {
        //展示登录后首页
    return \view();
    }

    /**
     * 显示创建资源表单页.
     *
     * @return \think\Response
     */
    public function create()
    {
        //展示登录页面
        return view();
    }

    /**
     * 保存新建的资源
     *
     * @param \think\Request $request
     * @return \think\Response
     */
    public function save(Request $request)
    {
        //
        $params = $this->request->post();
        //验证user表是否与用户输入的信息向匹配
        $data = AjaxModel::getLogininfo($params);
        if ($params['account'] != $data['username']) {
            $this->error('账号输入错误', '/ajax/ajax/create');
        }
        if ($params['password'] != $data['userpassword']) {
            $this->error('密码输入错误', '/ajax/ajax/create');
        }
     return json(['node'=>200,'massage'=>'success','data'=>$data]);
      
    }

3：模型代码

<?php

namespace app\ajax\model;

use think\Model;

class AjaxModel extends Model
{
    //查询user用户表
    protected $table = 'user';

    public static function getLogininfo($params)
    {
        return self::where('username', $params['account'])->find();
    }
}
