3--登录 和 验证格式

三种身份登录：

<?php
namespace app\api\controller;

use think\Controller;
use think\Db;

class Login extends Controller
{
    public function student(){
        $data=input('param.');
//        格式验证
        $result=$this->validate($data,'Student.student_login');
        if (true !== $result){
            return error($result);
        }
//      查找表内容
        $stu = Db::name('student')
            ->field('id,name,schoolid,tel,state,password')
            ->where('tel',$data['tel'])
            ->where('password',encry($data['password']))
            ->find();
//        print_r($stu);
//        exit();
        if (empty($stu)){
            return error('手机号或密码错误');
        }
        $token=token();
        $account['role']=4;
        cache($token,$stu,1800);
        return success(['message'=>'登录成功','token'=>$token,'role'=>4]);
    }

    public function classmanager(){
        $data=input('param.');
//        格式验证
        $result=$this->validate($data,'Banji.banji_login');
        if (true !== $result){
            return error($result);
        }
//      查找表内容
        $account=Db::name('account')
            ->field('id,name,account,tel,schoolid,state,type')
            ->where('account',$data['account'])
            ->where('password',encry($data['password']))
            ->find();
        if (empty($account)){
            return error('账号或密码错误');
        }
        if (3 !== $account['type']){
            return error('该账号不是班级管理员');
        }
        $token=token();
        $account['role']=3;
        cache($token,$account,1800);
        return success(['message'=>'登录成功','token'=>$token,'role'=>3]);
    }



    public function schoolmanager(){
        $data=input('param.');
//        格式验证
        $result=$this->validate($data,'School.school_login');
        if (true !== $result){
            return error($result);
        }
//      查找表内容
        $account=Db::name('account')
            ->field('id,name,account,tel,schoolid,state,type')
            ->where('account',$data['account'])
            ->where('password',encry($data['password']))
            ->find();
        if (empty($account)){
            return error('账号或密码错误');
        }
        if (2 !== $account['type']){
            return error('该账户不是学校管理员');
        }
        $token=token();
        $account['role']=2;
        cache($token,$account,1800);
        return success(['message'=>'登录成功','token'=>$token,'role'=>2]);
    }
}

验证：

<?php
namespace app\common\validate;
use think\Validate;

class Student extends Validate
{
    protected $rule=[
      'schoolid'=>'require|number|length:6,6',
      'tel'=>'require|number|length:11,11',
       'password'=>'require|length:6,10',
        'number'=>'require|number|length:10,10'
    ];

    protected $message=[
      'schoolid.require'=>'学校编码不能为空',
      'schoolid.number'=>'学校编码必须为数字',
       'schoolid.length'=>'学校编码必须是6位数字',
        'tel.require'=>'手机号不能为空',
        'tel.length'=>'手机号必须是11位',
        'number.require'=>'学号不能为空',
        'number.number'=>'学号必须为数字',
        'number.length'=>'学号必须为10位',
        'password.require'=>'密码不能为空',
        'password.length'=>'密码必须是6-10位'
    ];
    protected $scene = [
       'student_reg'=>['schoolid','tel','number','password'],
      'student_login'=>['tel','password'],
      'update_number'=>['number'],
        'update_tel'=>['tel'],
        'update_password'=>['password']
    ];
