tp5框架使用Token实现登录功能

composer 安装JWT

composer require lcobucci/jwt 3.3

前端代码参考：

<body>
<p style="color: #5a6268;font-size: 30px;font-weight: bold;text-align: center;">登录页面</p>
<form style="width: 30%;margin: 0 auto">
        <label>用户名</label>
        <input type="text" id="name" class="form-control" >
        <label >密码</label>
        <input type="password" id="pwd" class="form-control">
    <button type="button" class="btn btn-primary">确认登录</button>
</form>
</body>
</html>
<script>
    $('.btn').click(function () {
        var name=$(this).siblings('#name').val();
        var pwd=$(this).siblings('#pwd').val();
        $.ajax({
            "url":'/admin/login/login',
            "type":"POST",
            "data":{
                'name':name,
                'pwd':pwd,
                '__token__':"{$Request.token}",
            },
            "dataType":"json",
            "success":function (res) {
                console.log(res);
                if(res.code==200){
                    alert('登录成功');
                    localStorage.setItem('token',res.data);//将token上传到游览器本地化
                    window.location.href="{:url('home/login/login')}";
                }
            },
            "error":function (error) {
                console.log(error);
            }
        })
    })
</script>

在框架index/server/创建JwtServer.php这个类

<?php


namespace app\index\server;
use Firebase\JWT\JWT;
use Firebase\JWT\Key;
use phpDocumentor\Reflection\Types\False_;

class JwtServer
{
    public static function createToken($userId)
    {
        $key = "example_key";
        $payload = array(
            "iss" => "http://example.org",
            "aud" => "http://example.com",
            "iat" => 1356999524,
            "nbf" => 1357000000,
            'user_id'=>$userId
        );
        $jwt = JWT::encode($payload, $key, 'HS256');
        return $jwt;
    }
    public static function decodeToken($jwt){
        $key = "example_key";
        $decoded = JWT::decode($jwt, new Key($key, 'HS256'));
        if ($decoded){
            return $decoded->user_id;
        }else{
            return  false;
        }

    }
}

控制器代码参考：

<?php

namespace app\admin\controller;
use think\Controller;
use tools\jwt\Token;

class Login extends Controller
{
    public function login(){
        $param=request()->post();

        $data = [
            'name' =>$param['name'],
            'pwd' =>$param['pwd'],
        ];

        $res=\app\admin\model\logins::loginDo($data);
        if(!$res){
            return json(['code'=>0,'data'=>'','msg'=>'登录失败']);
        }else{
            $token = Token::createToken($res['id']);
　　　　　　　　
    　　session('token',$token);
        return json(['code'=>200,'data'=>$token,'msg'=>'登录成功']);
        }
    }
}

携带token

 

写一个基类方法判断token是否有值

 

 

 登录成功携带token
