yii2多文件上传接口开发(yii自带的UploadedFile类+postman

请先在frontend下创建一个uploads文件夹，否则不能生效哦
、路由：

<?php
/**
 * Created by PhpStorm.
 * User: Chan
 * Date: 2018/6/8
 * Time: 14:14
 */

use yii\rest\UrlRule;

return [
    [
        'class'=>UrlRule::class,
        'controller'=>'upmore',
        'extraPatterns' => ['upmore' => 'upmore'],
    ],
];

控制器：

<?php
namespace frontend\controllers;
use yii\base\Model;
use yii\web\Controller;
use yii\helpers\ArrayHelper;
use yii\helpers\FileHelper;
use common\models\Upmore;
use yii\web\UploadedFile;
use Yii;
class UpmoreController extends  Controller{
public $enableCsrfValidation = false;
    public function actionUpmore(){
        $model=new Upmore();
        if (Yii::$app->request->isPost) {
            $file = UploadedFile::getInstances($model, 'file');

            if ($file && $model->validate()) {


                foreach ($file as $fl) {
                    $fl->saveAs(Yii::$app->basePath."/uploads/".iconv("UTF-8", "GB2312//IGNORE", $fl->baseName). '.' . $fl->extension);
                
                Yii::$app->db->createCommand()->insert('upmore', [
            		'path' =>Yii::$app->basePath."/uploads/".iconv("UTF-8", "GB2312//IGNORE", $fl->baseName). '.' . $fl->extension,
            		'file' =>iconv("UTF-8", "GB2312//IGNORE", $fl->baseName). '.' . $fl->extension,
            		'created_at'=>date('Y-m-d H:i:s')
        		])->execute();
               
            }
        }
    }



} 
}

模型：

<?php

namespace common\models;

use Yii;

/**
 * This is the model class for table "upmore".
 *
 * @property integer $id
 * @property string $path
 * @property string $file
 * @property string $created_at
 */
class Upmore extends \yii\db\ActiveRecord
{     public $file;
    /**
     * @inheritdoc
     */

    public static function tableName()
    {
        return 'upmore';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
          return [
          [['file'], 'file', 'maxFiles' => 10,'extensions'=>'jpg,png,gif,txt,doc'],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'id' => 'ID',
            'path' => 'Path',
            'file' => 'File',
            'created_at' => 'Created At',
        ];
    }


}
