1、新建文件：dayrui/My/Model/Member.php

2、新写方法体：

<?php namespace My\Model;

// 重写系统模型类 不影响升级
class Member extends \Phpcmf\Model\Member
{

    // 短信登录
    public function login_sms($phone, $remember) {
    
        $data = $this->db->table('member')->where('phone', $phone)->get()->getRowArray();
        if (!$data) {
            //手机号码未注册
            $rt = $this->register(999999, [ // 99999是用户组号，需要手动改
                'username' => $phone,
                'phone' => $phone,
                'email' => '',
                'name' => $phone,
                'password' => dr_safe_password('1234'), // 初始密码
            ]);
            if (!$rt['code']) {
                return dr_return_data(0, $rt['msg'])
            }
            $data = $rt['data'];
        }
    
        $data['uid'] = $data['id'];
    
        // 保存本地会话
        $this->save_cookie($data, $remember);
    
        // 记录日志
        $this->_login_log($data);
    
        return dr_return_data(1, 'ok', [
                'auth'=> md5($data['password'].$data['salt']), // API认证字符串,
                'member' => $this->get_member($data['id']),
                'sso' => $this->sso($data, $remember)]
        );
    }

}
