IIS 10.0详细错误：mimeMap [英] IIS 10.0 Detailed Error: mimeMap

问题描述

你好，所以我很擅长使用IIS和Visual Studio，但我已经设法在IIS上启动了一个网站但是当我尝试启动这个网站时，我在页面上出现了这个错误：

Hello so I'm pretty new to using IIS and Visual Studio but I've managed to launch one website on IIS but when I try to launch this one I get this error across the page:

错误消息：

无法添加mimeMap类型的重复集合条目，其唯一键属性fileExtension设置为.mp4

Cannot add duplicate collection entry of type 'mimeMap' with unique key attribute 'fileExtension' set to '.mp4'

有一节读取 配置错误： 所以这是我的 web.config 档案：

There's a section that reads Config Error:so here is my web.config file:

推荐答案

您可以添加以下内容：

<remove fileExtension=".mp4" />

或者，因为MP4 mime类型似乎已经存在于根配置文件中，所以只需省略整行：

Or, since the MP4 mime type seems to be already present in the roots configuration file, simply omit the whole line:

<mimeMap fileExtension=".mp4" mimeType="video/mp4"/>

如果你真的想确定你似乎需要的扩展名存在，这可能是一个替换 staticContent 标记：

If you really want to be sure that the extensions you seem to require are present, this could be a replacement for the staticContent tag:

<staticContent>
    <remove fileExtension=".mp4" />
    <remove fileExtension=".m4v" />
    <remove fileExtension=".3gp" />

    <mimeMap fileExtension=".mp4" mimeType="video/mp4"/>
    <mimeMap fileExtension=".m4v" mimeType="video/m4v"/>
    <mimeMap fileExtension=".3gp" mimeType="video/3gpp"/>
</staticContent>
