控制器

public function postAuthorityDistribution()
{
    $post                        = request()->param();
    $permissionGroupUserModel    = new \app\api\model\PermissionGroupUser();
    $permissionGroupUserValidate = new \app\api\validate\PermissionGroupUser();
    //校验
    if (!$permissionGroupUserValidate->scene('list')->check($post)) {
        return $this->result(10003, $permissionGroupUserValidate->getError(), $this->time);
    }
    $res = $permissionGroupUserModel->permissionGroupUserList($post);
    return $this->result($res['code'], $res['msg'], $this->time, $res['data']);
}

模型

public function permissionGroupUserList($post){
    $user = $this;
    $res  = $this->transaction(function () use ($user, $post) {
        //保存
        $saveres = $user->allowField(true)->save($post);
        //$user->id 获取主键id 使用startTrans开启事务->id无法获取自增id 只能用insertGetId获取自增id
        //修改
        $saveres = $user->allowField(true)->isUpdate(true)->save($post);
        //过滤非表字段
        ->allowField(true)
        //标识更新操作
        ->isUpdate(true)
        // 返回操作结果
        return $saveres 
    });
    if ($res) {
        return model_true('用户编辑成功');
    } else {
        return model_false(10002, '用户编辑失败');
    }
}
public function permissionGroupUserList($post){
    $this->startTrans();
    try {
       
        $this->commit();
        return model_true("message");
    } catch (\Exception $e) {
        // 回滚事务
        $this->rollback();
        return model_false(10001, $e->getMessage());
    }
}

或者这种静态调用

public static function do_login_act($post)
{
    $info = self::where('user_login', $post['username'])->find();
    if (empty($info)) {
        return ['code' => 0, 'msg' => '账号不存在'];
    }
    if ($info['status'] == 2) {
        return ['code' => 0, 'msg' => '账号已禁用'];
    }
    if ($info['status'] == 4) {
        return ['code' => 0, 'msg' => '账号未激活'];
    }
    if (!password_compare($post['password'], $info['user_pass'])) {
        return ['code' => 0, 'msg' => '密码错误'];
    }
    $info['last_login_ip']   = get_client_ip(0, true);
    $info['last_login_time'] = time();
    $res                     = self::transaction(function () use ($info) {
        $info->allowField(true)->isUpdate(true)->save($info);
        return true;
    });
    if ($res) {
        unset($info['user_pass']);
        session('user', $info->toArray());
        session("login_type", "staff");
        return ['code' => 1, 'msg' => '登录成功', 'data' => ['url' => '/admin/index/index']];
    } else {
        return ['code' => 1, 'msg' => '登录失败，请重试。'];
    }
}

校验

<?php

namespace app\api\validate;

use think\Validate;

class User extends Validate
{

protected $start_time;
/**
 * 定义验证规则
 * 格式：'字段名'    =>    ['规则1','规则2'...]
 *
 * @var array
 */
protected $rule = [
    'group_id|用户组编号'    => 'require|number',
];

/**
 * 定义错误信息
 * 格式：'字段名.规则名'    =>    '错误信息'
 *
 * @var array
 */
protected $message = [
];
//List控制器成校验名称list
public function sceneList()
{
    return $this->only([
        'person_phone',
    ])->remove('person_phone', 'require');
}


// 自定义验证规则(第一个$value是被验证的数据，第二个是验证规则，第三个$data是所有的数据)
protected function start_time_validate($value)
{
    $time = strtotime($value);
    if ($time) {
        if ($time >= time()) {
            $this->start_time = $time;
            return true;
        } else {
            return '开始时间必须大于等于当前时间';
        }
    } else {
        return '不合法的时间格式';
    }
}

protected function end_time_validate($value)
{
    $time = strtotime($value);
    if ($time) {
        if ($time > $this->start_time) {
            return true;
        } else {
            return '结束时间必须大于开始时间';
        }
    } else {
        return '不合法的时间格式';
    }
}


}

自定义助手函数

if (!function_exists('model_true')) {

/**
 * @param string $msg
 * @param array $data
 * @return array
 * model返回数据
 */
    function model_true(string $msg = '操作成功', array $data = [])
    {
        return ['res' => true, 'msg' => $msg, 'code' => 0, 'data' => $data];
    }
}

if (!function_exists('model_false')) {
/**
 * @param int $code
 * @param string $msg
 * @param array $data
 * @return array
 * model返回数据
 */
    function model_false(int $code, string $msg = '操作失败', array $data = [])
    {
        return ['res' => false, 'msg' => $msg, 'code' => $code, 'data' => $data];
    }
}
