laravel提供了方便快捷的文件操作，与遇到第三方文件服务器，例如阿里云，七牛云等等如何处理上传的文件，下面案例是使用七牛云案例。
在laravel使用：
1，首先我们需要下载七牛云sdk，定义qiniuyun类库，具体一些配置就不写了，相信使用过第三方文件服务器工具都应该知道原理，如下
<?php
namespace Services;
use Illuminate\Support\Facades\Config;
use Qiniu\Auth;
use Qiniu\Storage\UploadManager;
use Qiniu\Storage\BucketManager;
class Qiniu {
//访问 key
private $accessKey;
//密钥
private $secretKey;
private $bucket;
private $token;
private $err;
private $ret;
/**
* @var array 七牛域名 绑定
*/
private $qiniu_domain = array(
'product-images' => 'https://dn-yidd-product-images.qbox.me',
'article-images' => 'https://dn-yidd-article-images.qbox.me',
'avator-images' => 'https://dn-yidd-avator-images.qbox.me',
'drugstore-images' => 'https://dn-yidd-drugstore-images.qbox.me',
'id-images' => 'https://dn-yidd-id-images.qbox.me',
'ue-images' => 'https://dn-yidd-ue-images.qbox.me',
'topic-images' => 'https://dn-yidd-topic-images.qbox.me',
'slide-images' => 'https://dn-ydd-slide-images.qbox.me',
'test-paper-images' => 'https://dn-ydd-test-paper-images.qbox.me',
'event-images' => 'https://dn-yidd-event-images.qbox.me',
'audio' => 'https://dn-yidd-audio.qbox.me',
'video' => 'https://dn-yidd-video.qbox.me',
'group-images' => 'https://dn-yidd-group-images.qbox.me',
);
/**
* @param $bucket 七牛空间名称
* @param bool $require_auth 是否需要权限
*/
public function __construct($bucket,$require_auth = false){
$this->bucket = $bucket;
if($require_auth){
$this->accessKey = Config::get('config.access_key');
$this->secretKey = Config::get('config.secret_key');
$this->auth = new Auth($this->accessKey, $this->secretKey);
$this->token = $this->auth->uploadToken($this->bucket);
}
}
/**
* @param $key 唯一存储名称
* @param $filePath 本地上传文件路径
*/
public function upload($key, $filePath){
$uploadMgr = new UploadManager();
list($ret, $err) = $uploadMgr->putFile($this->token, $key, $filePath);
if ($err !== null) {
$this->err = $err;
} else {
$this->ret = $ret;
$this->DeleteLocalImage($filePath);
return true;
}
}
/**
* 删除
* 唯一存储名称
* @param $key
*/
public function delete($key){
$bucketMgr = new BucketManager($this->auth);
$err = $bucketMgr->delete($this->bucket, $key);
if ($err !== null) {
return false;
} else {
return true;
}
}
/**
* @param $key 唯一存储名称
* @return string
*/
public function getFileUrl($key){
return $this->qiniu_domain[$this->bucket].'/'.$key;
}
/*
* 获取存储空间https地址
*
*/
public function getDomain(){
return $this->qiniu_domain[$this->bucket].'/';
}
/**
* 获取 token
* @return string
*/
public function getToken(){
return $this->token;
}
/**
* 返回错误
* @return mixed
*/
public function getErr(){
return $this->err;
}
/**
* 返回七牛返回值
* @return mixed
*/
public function getReturn(){
return $this->ret;
}
//删除本地图片
public function DeleteLocalImage($filePath){
$result = @unlink ($filePath);
return $result;
}
}
2，定义生成七牛云文件的命名规则的类库
<?php
namespace App\Services;
class Util{
private static $_instance;
public static function getUtilData(){
if(!self::$_instance){
self::$_instance = new Util();
}
return self::$_instance;
}
/**
* 七牛文件命令规则
1. 身份证：id_用户ID_时间戳.png
2. 头像：avatar_用户ID_时间戳.png
3. 药店营业执照：bl_药店名称_时间戳.png
4. 产品图片：product_产品ID_时间戳.png
5. 文章列表图片：artile_文章ID_时间戳.png
*
* * $id = 数据编号
* $type = 所代表的空间名称
*
*
* 4【'product'=>'产品图片'】id必传
* 5【'article'=>'文章图片'】id必传
* 8【'slide'=>'幻灯片'】 id 非必传
* 9【'test_paper'=>'题卷图片'】 id 必传
* 10【'event'=>'活动图片'】id必传
*
*
* @param $bucketType
* @param intval $id
* @param string $filename
* @return string
*/
public function create_qiniu_unqiue_name($bucketType,$id=false,$filename = ''){
$arr = [1=>'id',2=>'avator',3=>'drugstore',4=>'product',5=>'article',8=>'slide',9=>'test_paper',10=>'event'];
$name = $arr[$bucketType] ? $arr[$bucketType] : false;
if($name === false){
return false;
}
if($id === false){
$file_prefix = $name.'_';
}else{
$file_prefix = $name.'_'.$id.'_';
}
$ext = '';
if($filename != ''){
$ext = substr($filename,strrpos($filename,'.'));
}
list($u, $s) = explode(' ',microtime());
$s = date('ymdhis',$s);
$result = $s.($u* pow(10,2));
if(strpos($result,'.')){
list($result,$useless) = explode('.',$result);
}
$name = $file_prefix.$result.$this->getRandCode(6);
return $name.$ext;
}
/**

1. 身份证：id_用户ID_时间戳.png
2. 头像：avatar_用户ID_时间戳.png
3. 药店营业执照：bl_药店名称_时间戳.png
4. 产品图片：product_产品ID_时间戳.png
5. 文章列表图片：artile_文章ID_时间戳.png
*

* 13【'group'=>'群组头像'】id必传
*
*
* @param $bucketType
* @param intval $id
* @param string $filename
* @return string
*/
public function javascript_create_qiniu_unqiue_name($bucketType,$id=false){
$arr = [4=>'product',5=>'article',8=>'slide',9=>'test_paper',10=>'event',13=>'group'];
$name = $arr[$bucketType] ? $arr[$bucketType] : false;
if($name === false){
return false;
}
if($id === false){
$file_prefix = $name.'_';
}else{
$file_prefix = $name.'_'.$id.'_';
}
list($u, $s) = explode(' ',microtime());
$s = date('ymdhis',$s);
$result = $s.($u* pow(10,2));
if(strpos($result,'.')){
list($result,$useless) = explode('.',$result);
}
return $file_prefix.$result.$this->getRandCode(6);
}
/**
* 获取直定长度随机码
* @param type $length
* @param type $type 0 纯数字 1 数字、小写字母 2 数字、小写字母、大写字母
* @return string
*/
function getRandCode($length = 6,$type = 0)
{
if($type == 0) {
$str = '0123456789';
}else if($type == 1){
$str = '0123456789abcdefghijklmnopqrstuvwxyz';
}else{
$str = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
}
$len = strlen($str);
$retStr = '';
for($i=0;$i<$length;$i++){
$retStr .= $str[rand(0, $len-1)];
}
return $retStr;
}
}
3，好了，工具已经准备好了，我们开始吧，首先是新建一个html文件，当然laravel路由配置需要自己配置，在app\http\route.php中配置：
例如Route::any('User/add',['middleware'=>'auth','uses'=>'Backstage\User\UserController@add']);//新增会员
html中部分内容：
<form id="frm_add" name="frm_add" class="formbody" action="{{url('User/add')}}" method="post" enctype="multipart/form-data">
......
<li>
<span>头像</span>
<cite><input id="avatar" name="avatar" type="file"></cite>
</li>
.......
</form>
form提交过后,注：前端上传文件未做文件大小，类型作验证，有兴趣的，自己作验证，这里就在后端通过php代码进行验证了。
config中上传头像配置：
//上传头像文件的配置选项
'avatar' =>[
'size' => '2048000',
'extension' =>[
0 =>'jpg',
1 =>'jpeg',
2 =>'bmp',
3 =>'gif',
4 =>'png'
]
],
'bucket_key' => [
1 => 'id-images', //身份证
2 => 'avator-images', //头像
3 => 'drugstore-images', //药店营业执照
4 => 'product-images', //产品图片
5 => 'article-images', //文章图片
6 => 'topic-images', //话题图片章
7 => 'ue-images', //ueditor上传图片
8 => 'slide-images', //幻灯片
9 => 'test-paper-images', //题卷图片
10 => 'event-images', //活动图片
11 => 'audio', //音频
12 => 'video',// 视频
13 => 'group-images',// 群组头像
],
php代码：
控制器代码：
namespace App\Http\Controllers\Backstage\User;
use Illuminate\Http\Request;
use Services\Qiniu;
use Illuminate\Filesystem\Filesystem;
use Illuminate\Support\Facades\DB;
class UserController extends \App\Http\Controllers\Backstage\Controller {
.......
public function add(Request $request){
//实例化User模型对象，继承\Illuminate\Database\Eloquent\Model
$userLogic = new \App\Logics\UserLogic();
//判断是否是表单提交，所以在我们配置路由时候，路由的http请求方式不仅仅是get,而且也是post,参考
//laravel如何配置路由
if($request->isMethod('post')){
$temp_name = '';
$avatar_upload_path = '';
$path = "";
//判断表单提交是否含有文件操作
if($request->hasFile('avatar')){
//获取上传文件信息，返回结果集是一个对象，该对象可以获取到缓存在tmp文件夹中的文件
//名、上传文件的后缀、缓存在tmp文件夹下的文件的绝对路径、文件大小等等
$avatar = $request->file('avatar');
//get avatar config para
$avatar_config = config('config.avatar');
//判断上传文件格式是否合格
if(!in_array(strtolower($avatar->getClientOriginalExtension()),$avatar_config['extension'])){
show_message('上传文件格式错误,请重新上传!','goback',1000,0);exit;
}
//判断上传文件大小是否合格
if($avatar->getSize() > $avatar_config['size']){
show_message('上传文件过大,请上传不超过2M的文件!','goback',1000,0);exit;
}
//laraval 第三方扩展类库Filesystem,很强大，自行查询，laravel api文档
//https://laravel.com/api/5.0/Illuminate/Filesystem/Filesystem.html
$filesystem = new Filesystem();
//定义laravel项目中上传路径
$avatar_upload_path = public_path() . '/upload/avatar/';
//判断已定义的上传路径是否存在或者是否是不是只读，不符合条件我们创建该目录并且赋文件夹权限
if(!$filesystem->exists($avatar_upload_path) || !$filesystem->isWritable($avatar_upload_path)){
$filesystem->makeDirectory($avatar_upload_path, 0755, false, true);
}
//创建上传文件临时唯一名称
$temp_name = md5(\Carbon\Carbon::now()->timestamp.$avatar->getClientOriginalName()).'.'.$avatar->getClientOriginalExtension();
//move uploaded file to fixed public directory（将上传的文件移动到项目中的上传路径）
$path = $avatar->move($avatar_upload_path,$temp_name);
}
//插入操作
if(!empty($insertGetId = $userLogic->insertUser($request))){
//用户数据插入成功，判断上传文件以及上传路径是不是存在，符合条件，进行七牛云文件操作
if(!empty($temp_name) && !empty($avatar_upload_path) && $filesystem->exists($avatar_upload_path.$temp_name)){
//实例化工具类，创建上传到七牛云文件的名称：唯一
$utilService = new \App\Services\Util();
$avatar_name = $utilService->create_qiniu_unqiue_name(2,$insertGetId,$path);
if(!empty($avatar_name)){
//实例化七牛云操作类
$QiniuServices = new Qiniu(config('config.bucket_key')[2],true);
//七牛云上传文件
if(!empty($QiniuServices->upload($avatar_name, $path))){
$userLogic->where('id','=',$insertGetId)->update(['avatar'=>$avatar_name,'bucket_space'=>config('config.bucket_key')[2]]);
}
}
//delete uploaded file from local(删除本地项目上传文件)
$filesystem->delete($avatar_upload_path.$temp_name);
}
//记录操作日志
log_records('新增普通用户:'.$request->get('mobile'));
//show_message自定义的方法，就不写了
show_message('新增普通用户成功！', '/User/index', 1000,0);exit;
}else{
show_message('新增用户失败!','goback',1000,0);exit;
}
}
return view('backstage.user.add',$this->data);
}
.......
}
4，Logic文件夹中定义的部分代码如下：
<?php
namespace App\Logics;
use Illuminate\Support\Facades\DB;
/**

*/
class UserLogic extends \Illuminate\Database\Eloquent\Model{
protected $table = "user";
//put your code here
public function getList($data = []){
if (!empty($data['sortby']) && !empty($data['sortvalue'])) {
$sortby = $this->table.'.'.$data['sortby'];
$sortvalue = trim($data['sortvalue']);
} else {
$sortby = $this->table.'.id';
$sortvalue = 'desc';
}
$list = DB::table($this->table)
->where(function($query) use($data) {
if (!empty($data['mobile'])) {

}
})
->select('id','realname','nickname','mobile','score','phone','lastlogin','is_active')
->orderBy($sortby, $sortvalue)
->take($data['pageSize'])
->skip($data['pageNo'] > 1 ? ($data['pageNo'] - 1) * $data['pageSize'] : 0)
->get();
$count = 0;

}
return [$list, $count];
}
public function getUserInfoById($id){
return self::find($id);
}
public function insertUser(\Illuminate\Http\Request $request){
if(!empty($request->get('realname',''))){
$data['realname']= strval($request->get('realname',''));
}
$data['nickname']= strval($request->get('nickname',''));

}
是不是很简单，动手操作下吧
