今天把项目中上传功能封装成类，方便后面使用，简单的封装了一下，感觉还不怎么好，后面继续优化。
具体代码如下：
<?php
/**
namespace AppThinkClass;
use SymfonyComponentHttpFoundationFileUploadedFile;
class UploadClass
{
/**
protected $file;
/**
private $error = ''; //上传错误信息
private $fullPath='';//绝对地址
private $config = array(
'maxSize' => 3
1024, //上传的文件大小限制 (0-不做限制)
'exts' => array('jpg','jpeg','gif','png','doc','docx','xls','xlsx','ppt','pptx','pdf','rar','zip'), //允许上传的文件后缀
'subName' => '', //子目录创建方式，[0]-函数名，[1]-参数，多个参数使用数组
'rootPath' => '/uploads/', //保存根路径
'savePath' => '', //保存路径
'thumb' => array(),//是裁剪压缩比例
);
public function __construct($config = array()){
/
/
$this->config = array_merge($this->config, $config);
if(!emptyempty($this->config['exts'])){
if (is_string($this->exts)){
$this->config['exts'] = explode(',', $this->exts);
}
$this->config['exts'] = array_map('strtolower', $this->exts);
}
$this->config['subName'] = $this->subName ? ltrim($this->subName,'/') : '/'.date('Ymd');
$this->fullPath = rtrim(public_path(),'/').$this->config['rootPath'];
}
public function __get($name) {
return $this->config[$name];
}
public function __set($name,$value){
if(isset($this->config[$name])) {
$this->config[$name] = $value;
}
}
public function __isset($name){
return isset($this->config[$name]);
}
/**
public function getError(){
return $this->error;
}
public function upload($fi/
/le){
if(emptyempty($file)){
$this->error = '没有上传的文件';
return false;
}
if(!$this->checkRootPath($this->fullPath)){
$this->error = $this->getError();
return false;
}
$fileSavePath=$this->fullPath.$this->savePath.$this->subName;
if(!$this->checkSavePath($fileSavePath)){
$this->error = $this->getError();
return false;
}
$files =array();
if(!is_array($file)){
//如果不是数组转成数组
$files[]=$file;
}else{
$files=$file;
}
$info = array();
$imgThumb = new AppThinkClassThumbClass();
foreach ($files as $key=>$f){
$this->file=$f;
$f->ext = strtolower($f->getClientOriginalExtension());
/
/
if (!$this->check($f)){
continue;
}
$fileName = str_random(12).'.'.$f->ext;
/
/
if ($this->file->move($fileSavePath,$fileName)) {
/
/
Log::notice($fileSavePath.$fileName);
if(!emptyempty($this->thumb) && is_array($this->thumb)){
$imgThumb ->thumb($this->thumb,$fileSavePath.'/'.$fileName);
}
$info[]=$this->rootPath.$this->savePath.$this->subName.'/'.$fileName;
}
}
return is_array($info) ? $info : false;
}
/**
protected function checkRootPath($rootpath){
if(!(is_dir($rootpath) && is_writable($rootpath))){
$this->error = '上传根目录不存在！';
return false;
}
return true;
}
/**
public function checkSavePath($savepath){
/
/
if (!$this->mkdir($savepath )) {
return false;
} else {
/
/
if (!is_writable($savepath)) {
$this->error = '上传目录不可写！';
return false;
} else {
return true;
}
}
}
/**
private function check($file) {
/
/
if (!$this->checkSize($file->getSize())) {
$this->error = '上传文件大小不符！';
return false;
}
/
/
if (!$this->checkExt($file->ext)) {
$this->error = '上传文件后缀不允许';
return false;
}
/
/
return true;
}
/**
private function checkSize($size) {
return !($size > $this->maxSize) || (0 == $this->maxSize);
}
/**
private function checkExt($ext) {
return emptyempty($this->config['exts']) ? true : in_array(strtolower($ext), $this->exts);
}
/**
protected function mkdir($savepath){
if(is_dir($savepath)){
return true;
}
if(mkdir($savepath, 0777, true)){
return true;
} else {
$this->error = "目录创建失败";
return false;
}
}
}
使用案例：
头部引用 use AppThinkClassUploadClass;
$upload = new UploadClass();
$upload->exts=array('jpg','png');
$upload->maxSize=5
1024;
$upload->savePath='course/uid_6';
$file = $request->file('fileImg');
$aa = $upload->upload($file);
dd($aa);
