问题描述
我正在使用Spatie's Media Library上传文件。
return MediaStream::create('prefix-'.$model->name.'.zip')->addMedia($mediaFiles);
在macOS中,我下载了该zip文件,当我双击它时,它会自动解压缩文件并将其保存在一个文件夹中,该文件夹的名称与.zip文件名中指定的名称相同(例如prefix-model.zip
)。到现在为止还挺好。但是,Windows 10用户报告说,使用WinZip解压缩的文件并没有在文件夹内解压缩,只有文件解压缩了。
为什么会这样?还是有一种变通办法或其他方法来确保.zip文件在文件夹内解压缩,而不在没有文件夹的情况下不直接解压缩文件?
这是所有方法的类别:

There are several options here,但是似乎没有任何方法可以强制将文件保存在文件夹中……是吗?
