flarum的上传需要安装插件

虽然是官方插件，但为了快速，这货把自己这个功能阉割了，需要的还得自己装，插件名字：FoF Upload   官方地址：https://flarum.org/extension/fof/upload 

看介绍还支持第三方存储，但需要命令去设置，看着脑壳疼

Features

• For images:
  • Auto watermarks.
  • Auto resizing.
• Mime type to upload adapter mapping.
• Whitelisting mime types.
• Uploading on different storage services (local, imgur, AWS S3 for instance).
• Drag and drop uploads.
• Uploading multiple files at once (button and drag and drop both support this).
• Easily extendable, the extension heavily relies on Events.
• Extender interface to disable or force particular adapters (see below)
