Laravel-将PHP资源传递到Storage :: put [英] Laravel - Passing a PHP resource to Storage::put

问题描述

Laravel文档( https://laravel.com/docs/5.2/filesystem#存储文件)声明如下:

The Laravel docs (https://laravel.com/docs/5.2/filesystem#storing-files) state this:

存储文件

put方法可用于将文件存储在磁盘上.您也可以将PHP资源传递给put方法，该方法将使用Flysystem的基础流支持.在处理大文件时，强烈建议使用流:

Storage::put('file.jpg', $contents);

Storage::put('file.jpg', $resource);

Storing Files

The put method may be used to store a file on disk. You may also pass a PHP resource to the put method, which will use Flysystem's underlying stream support. Using streams is greatly recommended when dealing with large files:

Storage::put('file.jpg', $contents);

Storage::put('file.jpg', $resource);

我正在寻找一个大于php内存限制(512MB)的文件，所以当我这样做时，出现内存错误:

I am looking to save a file larger than my php memory limit (512MB), so when I do this, I get a memory error:

Local.php第128行中的FatalErrorException:耗尽的内存大小为536870912字节(尝试分配377028088字节).

FatalErrorException in Local.php line 128: Allowed memory size of 536870912 bytes exhausted (tried to allocate 377028088 bytes).

如何使用文档中指示的流功能?如何从文件路径转到"PHP资源"?

How do I use the streaming functionality as indicated in the docs? How do I go from a file path to a "PHP resource"?

推荐答案

PHP不允许您上传具有该大小的文件.文档中指出的资源是这种 PHP资源

PHP is not allowing you to upload a file with that size. The resource that is being pointed out in the docs are this kind of PHP resource

这是使用干预从外部图像URL创建图像的简单示例.干预库使用GD库，该库位于PHP资源列表下.

Here's a simple example of creating an image from an external image URL using Intervention. The Intervention library uses the GD library, which is under the PHP resource list.

$image = Image::make('Your Extenal URL')->stream();
Storage::put('image_name.jpg', $image->getContents());   

以您为例，这是有关上传文件的示例代码.

In your case, here's an example code on uploading a file.

$file = Request::file('file_field');
Storage::put($file->getClientOriginalName(), File::get($file));
