How to implement single file and multiple file upload in laravel

#The code is super concise and easy to understand! ! ! (Welcome to add~)

First set the route for uploading files:

Route::post(&#39;upload/images&#39;[&#39;as&#39;=>&#39;uploadImages&#39;,&#39;uses&#39;=>&#39;UploadController@uploadImages&#39;]);  
 Route::post(&#39;upload/multiUpload&#39;[&#39;as&#39;=>&#39;multiUpload&#39;,&#39;uses&#39;=>&#39;UploadController@multiUpload&#39;]);

Then set the uploads disk address, which will be used to store files later. config / filesystem : disks

 &#39;disks&#39; => [
 
        &#39;local&#39; => [
            &#39;driver&#39; => &#39;local&#39;,
            &#39;root&#39; => storage_path(&#39;app&#39;),
        ],
 
        &#39;uploads&#39;=>[
            &#39;driver&#39;=>&#39;local&#39;,
            &#39;root&#39;=>public_path(&#39;uploads/&#39;),
        ]
    ],

Finally UploadController defines the upload function (use the disk method of Storage to access the uploads disk, which is set in the previous filesystem file)

putFile method: manage files to the specified The storage location, for example, the file name is automatically generated, or it can be set manually ('20190705', $file, 'test.png')

 //上传单张图
 public function uploadImages(Request $request)
    {
        if ($request->isMethod(&#39;post&#39;)) {
            $file = $request->file(&#39;file&#39;);
            if($file->isValid()){
                $path = Storage::disk(&#39;uploads&#39;)->putFile(date(&#39;Ymd&#39;) , $file);
                if($path) {
                    return [&#39;code&#39; => 0 , &#39;msg&#39; => &#39;上传成功&#39; , &#39;data&#39; => $path];
                }
                else {
                    return [&#39;code&#39; => 400 , &#39;msg&#39; => &#39;上传失败&#39;];
                }
            }
        } else {
            return [&#39;code&#39; => 400, &#39;msg&#39; => &#39;非法请求&#39;];
        }
    }
//上传多张图
 public function multiUpload(Request $request)
    {
        if($request->method(&#39;post&#39;)){
            $files = $request->allFiles();
            if(is_array($files)){
                foreach($files as $file){
                    $path = Storage::disk(&#39;uploads&#39;)->putFile(date(&#39;Ymd&#39;) , $file);
                }
                if( $path ) {
                    return [&#39;code&#39; => 0 , &#39;msg&#39; => &#39;上传成功&#39; , &#39;data&#39; => $path];
                }
                else {
                    return [&#39;code&#39; => 400 , &#39;msg&#39; => &#39;上传失败&#39;];
                }
            }
        }else{
            return [&#39;code&#39; => 400, &#39;msg&#39; => &#39;非法请求&#39;];
        }
    }
