Laravel File Storage: How to store (decoded) base64 image?
提问by PeraMika
How to store base64 image using the Laravel's filesytem (File Storage)methods?
如何使用Laravel 的文件系统（文件存储）方法存储 base64 图像？
For example, I can decode base64 image like this:
例如，我可以像这样解码 base64 图像：
base64_decode($encoded_image);
but all of the Laravel's methods for storing files can accept either a Illuminate\Http\Fileor Illuminate\Http\UploadedFileinstance.
但是 Laravel 的所有存储文件的方法都可以接受 aIlluminate\Http\File或Illuminate\Http\UploadedFileinstance。
So I guess I'd have to convert base64 image (or decoded base64 image) to Illuminate\Http\Fileor Illuminate\Http\UploadedFile, but how?
所以我想我必须将 base64 图像（或解码的 base64 图像）转换为Illuminate\Http\Fileor Illuminate\Http\UploadedFile，但是如何？

Just use putto store the encoded contents:
仅用于put存储编码内容：
Storage::put('file.jpg', $encoded_image);
All it's doing is wrapping file_put_contents.
它所做的只是包装file_put_contents.
Then to read it back out:
然后再读出来：
$data = base64_decode(Storage::get('file.jpg'));
Which, you guess it, is wrapping file_get_contents.
你猜对了，它正在包装file_get_contents.
