PHP 处理
<?php
if ($this->request->isAjax()){
header('Access-Control-Allow-Origin:*');
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
$file = $_FILES['file'];
$ext_arr = explode('.',$file['name']);
$filename = md5($file['name']).".".$ext_arr[1];
$file_path = "upload/shipin/";
file_put_contents($file_path.$filename, file_get_contents($file['tmp_name']), FILE_APPEND);
$end = request()->post('end');
if ($end==1){
$data['store_id'] = $this->_store_id;
$data['urls'] = "/".$file_path.$filename;
$data['addtime'] = time();
Db::name("store_shipin")->where('store_id',$data['store_id'])->insert($data);
$this->success('上传成功','',$file_path.$filename);
}
}
效果：
文件上传存放目录：D:\wamp64\www\up6\db\upload\2019\04\19\920144c756af424ca59136be71cf9209
大文件上传至后台服务端，统一放置。
