如何设置内容类型标头以响应 Pyramid Web 框架中的特定文件类型 [英] How to set the content type header in response for a particular file type in Pyramid web framework

问题描述

我正在使用金字塔网络框架来构建网站.我一直在 Chrome 控制台中收到此警告:

I am using pyramid web framework to build a website. I keep getting this warning in chrome console:

资源被解释为字体但使用 MIME 类型 application/octet-stream: "http:static/images/fonts/font.woff".

Resource interpreted as Font but transferred with MIME type application/octet-stream: "http:static/images/fonts/font.woff".

如何消除此警告消息?

我已经配置了使用 add_static_view

我可以想到一种方法，通过为响应添加一个订阅者函数来检查路径是否以 .woff 结尾，并将响应头设置为 application/x-font-woff.但它看起来不像一个干净的解决方案.有没有办法通过一些设置告诉 Pyramid 这样做.

I can think of a way to do this by adding a subscriber function for responses that checks if the path ends in .woff and setting the response header to application/x-font-woff. But it does not look like a clean solution. Is there a way to tell Pyramid to do it through some setting.

推荐答案

Pyramid 使用标准 mimetypes 模块 根据扩展猜测 mimetype.它调用:

Pyramid uses the standard mimetypes module to guess the mimetype based on the extension. It calls:

mimetypes.guess_type(path, strict=False)

如果在该平台上，模块会在 Windows 注册表中查找，并在以下位置查找 mimetype 列表:

The module looks in the Windows registry if on that platform, and in the following locations for mimetype lists:

knownfiles = [
    "/etc/mime.types",
    "/etc/httpd/mime.types",                    # Mac OS X
    "/etc/httpd/conf/mime.types",               # Apache
    "/etc/apache/mime.types",                   # Apache 1
    "/etc/apache2/mime.types",                  # Apache 2
    "/usr/local/etc/httpd/conf/mime.types",
    "/usr/local/lib/netscape/mime.types",
    "/usr/local/etc/httpd/conf/mime.types",     # Apache 1.2
    "/usr/local/etc/mime.types",                # Apache 1.3
    ]

您可以扩展这些文件之一，也可以创建自己的文件并使用 .init() 函数将其添加到模块中.

You can either extend one of those files, or create your own file and add it to the module using the .init() function.

文件格式很简单，只需列出 mimetype，然后是一些空格，然后是空格分隔的扩展名列表:

The file format is simple, just list the mimetype, then some whitespace, then a space-separated list of extensions:

application/x-font-woff     woff
