如何重置 IIS Express 默认 MIME 类型/静态内容？答案

【问题标题】：How do I reset IIS Express default mime types / staticContent?如何重置 IIS Express 默认 MIME 类型/静态内容？

【问题描述】：

我遇到了一个问题，即在执行 jQuery $.getJSON 调用时，没有将 .json 文件发送给客户端。它返回一个 404.3 IIS 错误消息，告诉我转到我的 IIS 安装目录并输入命令：

appcmd set config /section:staticContent /+[fileExtension='.xyz',mimeType='text/plain']

在我的例子中，.xyz 是 .json，mimeType 是 application/json。

后来我发现，我可以简单地在我的 web.config 文件中添加一个 staticContent 元素，这是我的生产托管解决方案所必需的。

<staticContent>
  <mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>

所以我这样做了，但后来 IIS 抱怨重复处理 .json 文件，所以我回到我的 IIS 安装目录并运行

appcmd clear config /section:staticContent 回想起来缺少要删除哪个 mimetype 的参数。

所以现在当我尝试加载我的页面时，IIS 给了我相同的 404.3 错误消息，只是现在它在抱怨 .html 扩展名。

在我看来，我从 IIS 中删除了所有默认的 mime 类型，现在我不知道如何取回它们。谁能帮帮我？

编辑 2015 年 11 月 5 日：我在上面说错了。这都是 IIS Express，而不是 IIS

【解决方案1】：

唯一的方法是重新安装 IIS（包括 Process Activation Service），这将删除您的所有配置。我强烈建议您在安装 IIS 时使用其他名称复制 ApplicationHost.config 的备份，以防万一发生重大问题并且您至少可以恢复到安装时间。还要启用配置历史记录，以便 IIS 在发生更改时自动复制备份，您可以保留 N 个副本。

正确的方法是在“”之前添加一个“”。如果它在父配置中不存在，IIS 将不会抱怨并且会工作，如果它存在，那么您将防止出现重复的问题锯。

现在，我建议您从其他 IIS 复制该部分。如果有帮助，这是我的，我认为这是 Windows 8.1 附带的默认设置

【讨论】：

请注意，由于长度原因，它不允许我添加所有内容，但以下是上面不适合的其余内容：
最后一个：
所以我查看了 IIS Express ApplicationHost.config 文件，似乎指定了所有这些 mime 类型，但我仍然从 IIS 收到 404.3 Not Found 错误消息。我正在使用 Visual Studio 来构建和运行该项目，所以我假设它实际上是在 IIS 上托管它的，对吧？还有其他地方可以设置 mime 类型吗？ IIS 管理器告诉我所有这些 mime 类型都有一个“继承”条目类型，除了在我的机器名称树的顶部列出“本地”。
我什至尝试卸载 IIS 和（关闭 Windows 功能）和 Process Activation Service 并重新安装无济于事。我不知道现在该怎么办。
好吧，如果你使用的是 IIS Express，情况就会大不相同，因为我想说你可以打开配置文件，例如：C:\Users\carlosag\Documents\IISExpress\config\applicationhost .config 并查看该部分是否存在。如果没有，您应该能够只删除该文件甚至整个 C:\Users\carlosag\Documents\IISExpress\ 文件夹，并且下次您使用带有“主”配置副本的 IIS Express 时将重新生成程序中的配置文件。
