Why a-upload support drag to upload by default? Why a-upload supports drag to upload by default? #4144
Description
- I have searched the issues of this repository and believe that this is not a duplicate.
Version
undefined
Environment
/
Reproduction link
https://antdv.com/components/upload-cn
Steps to reproduce
Try drag a file or image over the a-upload component (not a-upload-dragger)， then the file will be uploaded.
拖拽文件或图片到a-upload组件（而不是a-upload-dragger）上，文件也会被上传
What is expected?
The file should not be uploaded.
文件不应该被上传，因为这不是a-upload-dragger；就算默认支持拖拽，那这也没有有好的提示（例如，鼠标移动到上传组件上，上传组件提示用户可以在这里松鼠标，以上传文件）。
What is actually happening?
The dragged over files uploaded.
文件被上传了。
所以这里到底为什么要设计默认支持拖拽上传？倒不是希望不支持，而是这个功能太隐蔽了吧——用户鼠标拖文件的时候完全意识不到这个小上传按钮支持拖拽，是不是可以加一点提示？
