推荐答案

这不是一篇非常好的文章或技术IMO。您需要确保path是服务器文件系统上文件的物理位置。如果您查看文章的底部，则会介绍如何使用该链接。由于我们不知道您是如何调用代码的，我们无法确切地说出问题所在，但正如我所说的路径需要引用服务器文件系统上的图像。

That's not a very good article or technique IMO. You need to ensure the "path" is the physical location of the file on the server's file system. If you look at the bottom of the article there is a description of how to use the link. As we don't know how you are calling your code we can't really say what the problem is, but as I said "path" needs to refer to an image on the server's file system.

简答：你不能。压缩不是无限的。



唯一可行的方法是制作缩略图（小图片）

你需要通过减少缩小图片尺寸像素数高度和宽度。
