使用ASP.NET Development Server设置MIME类型 [英] Setting MIME types using the ASP.NET Development Server

问题描述

我在web.config文件中添加了以下内容，但是Visual Studio 2010中内置的开发服务器似乎忽略了这一点。有谁知道如何更改开发服务器中的MIME类型？

I added the following to the web.config file, but this seems to be ignored by the development server thats built into Visual Studio 2010. Does anyone know how to alter the MIME types in the development server?

<system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true"/>
    <staticContent>
        <mimeMap fileExtension=".mp4" mimeType="video/mp4" />          
        <mimeMap fileExtension=".ogg" mimeType="audio/ogg" />          
        <mimeMap fileExtension=".oga" mimeType="audio/ogg" />          
        <mimeMap fileExtension=".ogv" mimeType="video/ogg" />          
        <mimeMap fileExtension=".webm" mimeType="video/webm" />     
    </staticContent>  
</system.webServer>

推荐答案

Visual Studio中的内置开发Web服务器（ Cassini）不知道< system.webServer> ，只有IIS7.x或IIS7.5 Express才会使用这些设置。

The built-in development web server in Visual Studio (Cassini) has no knowledge of <system.webServer>, only IIS7.x or IIS7.5 Express will consume these settings.

Visual Studio的开发Web服务器中的静态文件内容类型也是硬编码的。

Also the static file content types in Visual Studio's development web server are hard coded.

来自 Microsoft.VisualStudio.WebHost.Connection （使用.NET Reflector反汇编）：

From Microsoft.VisualStudio.WebHost.Connection (disassembled using .NET Reflector):

private static string MakeContentTypeHeader(string fileName)
{
    string str = null;
    FileInfo info = new FileInfo(fileName);
    switch (info.Extension.ToLowerInvariant())
    {
        case ".bmp":
            str = "image/bmp";
            break;

        case ".css":
            str = "text/css";
            break;

        case ".gif":
            str = "image/gif";
            break;

        case ".ico":
            str = "image/x-icon";
            break;

        case ".htm":
        case ".html":
            str = "text/html";
            break;

        case ".jpe":
        case ".jpeg":
        case ".jpg":
            str = "image/jpeg";
            break;

        case ".js":
            str = "application/x-javascript";
            break;
    }
    if (str == null)
    {
        return null;
    }
    return ("Content-Type: " + str + "\r\n");
}

老实说，随着IIS7.5 Express的出现我不能了解为什么要使用内置的Web服务器。 Cassini在生产服务器上的部署时间可能是如此混乱的原因，因为它与真正的交易（安全性，配置等）完全不同，而如果你可以让你的网站在IIS7.5 Express上运行，那么它就相当高部署到生产IIS7.5服务器上的概率将正常工作。

To be honest, with the advent of IIS7.5 Express I can't see why you'd want to use the built-in web server. Cassini can be the cause of so much confusion when it comes to deployment time on a production server because it's nothing like the real deal (security, configuration etc) whereas if you can get your site running on IIS7.5 Express then there's a fairly high probability that deployment onto a production IIS7.5 server will "just work".

如果微软从下一版本的Visual Studio中取出Cassini服务器，我不会感到惊讶考虑到使用IIS7.5 Express运行是多么容易。

I wouldn't be surprised if Microsoft yanked the Cassini server from the next version of Visual Studio given how easy it is to run with IIS7.5 Express.
