2、控制器部分

<?php
namespace app\index\controller;

// 引入系统数据类
use think\Db;
// 引入系统控制器类
use think\Controller;

class Index extends Controller
{
    public function index()
    {
        return view();
    }

    public function zhuce()
    {

        if(!$_POST){
            return view();
        }

        $username = $_POST["username"];
        $password = $_POST["password"];
        // $password2 = $_POST["password2"]; // 此处忽略两次密码校验

        $data = '';
        $code = '';
        $msg = '';
        
        // 从数据库中读取数据
        $ifExit = Db::table('user')->where('username', $username)->find();

        if($ifExit){
            $msg = '用户已存在,请勿重复注册';
            $code = -1;
        }else{
            $data = [
                "username" => $username,
                "password" => $password
            ];
            $userId = Db::table('user')->insertGetId($data);
            $data['id'] = $userId;
            $code = 0;
        }
    
        $res = [
            "data" => $data,
            "code" => $code,
            "msg" => $msg
        ];

        return json_encode($res, JSON_UNESCAPED_UNICODE);
    }

    public function login()
    {

        if(!$_POST){
            return view();
        }

        $username = $_POST["username"];
        $password = $_POST["password"];

        $data = '';
        $code = '';
        $msg = '';
        
        // 从数据库中读取数据
        $ifExit = Db::table('user')->where('username', $username)->find();

        if(!$ifExit){
            $msg = '用户不存在';
            $code = -1;
        }else{
            if($password != $ifExit["password"]){
                $msg = '密码错误';
                $code = -1;
            }else{
                $data = $ifExit;
                $code = 0;
            }
        }
    
        $res = [
            "data" => $data,
            "code" => $code,
            "msg" => $msg
        ];

        return json_encode($res, JSON_UNESCAPED_UNICODE);
    }
}

3、数据库部分

 

 最后的效果:

注册校验:

 

登录校验:

 

 

最后:这个例子只是为了入门TP做的简单的尝试,实际应用的登录和注册往往要复杂得多,比如防注水的验证码等。
