无法下载某类特殊附件时报错404文件不存在，错误代码0x80070002的解决方法：IIS添加MIME扩展类型及常用的MIME类型列表(VSD/CAD/DWG/ISO)

---

：我在用IIS做为下载服务器的时候，有时传上去的文件比如 xxx.iso 文件明明是传上去了，但是用http打开的时候确显示为 404 文件不存在，错误代码：0x80070002。

这其实是IIS对文件的一种保护，是IIS服务器的一个安全性措施，不在IIS指定的MIME类型里的文件显不会操作。

觉见的有 mp4 / flv / iso / 7z / apk / vsd / vsdx / dwg 等扩展名的文件 IIS 本身是没有指定MIME类型的，这类文件默认在IIS里是不能下载的。

我们可以打开IIS 在 本地服务器上 右键 -> 属性 然后在 MIME类型 中查看已经的MIME格式：

比如我们需要IIS支持 MP4 文件下载可以这么设置：（这里我们对IIS全局进行设置、如果只针对某一个站点可以直接设置站点的）

1、在 网站 上右键 选属性

2、在打开的 网站 属性 上选择 HTTP 头 再点 MIME类型按钮

3、在打开的窗本中 点下 新建

4、在弹出的 MIME类型框上扩展名 MP4 MIME类型为： application/octet-stream，这样IIS就可以支持 MP4下载了。

下面列出一些常用的扩展名的 MIME类型

如果不知道MIME类型 可以写通用的：application/octet-stream，还有一些规律如果是文本类的让IE可以直接打开的 MIME 可以为 text/扩展名，如果是音频打开的时候让windows自动播放的可以用 audio/扩展名。
