Php 上载表单仅在Firefox中上载ASCII.stl 3D文件时有效
uploadform.html和upload_file.php（如下）在Firefox中工作正常，但在Chrome、IE和Safari中上载ASCII.stl 3D文件时失败。错误消息为“无效文件”，多台计算机和多个.stl文件出现问题。当我修改代码以支持其他文件类型（如JPG和PDF）时，它允许在所有四种web浏览器中使用这些文件类型。另外，Firefox只允许在mime类型部分包含application/octet流时上传.stl。为什么这在Firefox之外不起作用 uploadform.html:Php 上载表单仅在Firefox中上载ASCII.stl 3D文件时有效,php,forms,post,mime-types,Php,Forms,Post,Mime Types,uploadform.html和upload_file.php（如下）在Firefox中工作正常，但在Chrome、IE和Safari中上载ASCII.stl 3D文件时失败。错误消息为“无效文件”，多台计算机和多个.stl文件出现问题。当我修改代码以支持其他文件类型（如JPG和PDF）时，它允许在所有四种web浏览器中使用这些文件类型。另外，Firefox只允许在mime类型部分包含application/octet流时上传.stl。为什么这在Firefox之外不起作用 uploadform.
