javascript - 强制对 JavaScript 文件进行 GZIP 压缩

Question

我正在尝试压缩所有网站文件以优化网站性能。到目前为止，我已经包含了 HTML5 boilerplate .htaccess 中的压缩部分。例子。

这是相关的代码片段:

# ------------------------------------------------------------------------------
# | Compression                                                                |
# ------------------------------------------------------------------------------

<IfModule mod_deflate.c>

# Force compression for mangled headers.
# http://developer.yahoo.com/blogs/ydn/posts/2010/12/pushing-beyond-gzipping
<IfModule mod_setenvif.c>
    <IfModule mod_headers.c>
        SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)\s*,?\s*)+|[X~-]{4,13}$ HAVE_Accept-Encoding
        RequestHeader append Accept-Encoding "gzip,deflate" env=HAVE_Accept-Encoding
    </IfModule>
</IfModule>

# Compress all output labeled with one of the following MIME-types
# (for Apache versions below 2.3.7, you don't need to enable `mod_filter`
#  and can remove the `<IfModule mod_filter.c>` and `</IfModule>` lines
#  as `AddOutputFilterByType` is still in the core directives).
<IfModule mod_filter.c>
    AddOutputFilterByType DEFLATE application/atom+xml \
                                  application/javascript \
                                  application/json \
                                  application/rss+xml \
                                  application/vnd.ms-fontobject \
                                  application/x-font-ttf \
                                  application/x-web-app-manifest+json \
                                  application/xhtml+xml \
                                  application/xml \
                                  font/opentype \
                                  image/svg+xml \
                                  image/x-icon \
                                  text/css \
                                  text/html \
                                  text/plain \
                                  text/x-component \
                                  text/xml
</IfModule>

</IfModule>

查看 gzipwtf.com 后，客户网站似乎对所有 CSS 文件进行了 GZIP 压缩，但由于某种原因，JavaScript 被忽略了。我对 .htaccess 的乐趣和这方面的事情还很陌生，所以我不确定如何进行强制压缩。有什么建议吗？

Answer 1

为确保正确的互操作性，您需要为 JavaScript 指定两种 MIME 类型:

application/javascript
text/javascript

还有一个，不过只在过渡期用过:

application/x-javascript
