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：

<?phpnamespace 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',];}}

**sql：注意注意，sqlid要自增
