How can I use gzip compression for .css and .js files on my websites?
提问by zxon
I have been toiling for days to get gzip compression working on the websites I have on my shared hosting server. I've had a certain level of success but sadly .css and .js files are being left out, despite my best efforts. Since I'm using shared hosting, I have no access to the apache configuration file, so I have resorted to using my .htaccess file to achieve this.
我已经工作了好几天才能在我的共享托管服务器上的网站上使用 gzip 压缩。我已经取得了一定程度的成功，但遗憾的是 .css 和 .js 文件被排除在外，尽管我尽了最大努力。由于我使用的是共享主机，我无法访问 apache 配置文件，因此我使用我的 .htaccess 文件来实现这一点。
The site I'm currently working on is Peak Heat, running Wordpress, and below is the .haccess file I'm using:
我目前正在使用的网站是Peak Heat，运行 Wordpress，下面是我正在使用的 .haccess 文件：
# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/js
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

</ifModule>
When I check the site using Firebug v1.8.3 with Google PageSpeed v1.12, it shows that the following files haven't been compressed:
当我使用 Firebug v1.8.3 和 Google PageSpeed v1.12 检查站点时，它显示以下文件尚未压缩：
/wp-includes/js/jquery/jquery.js?ver=1.6.1
/wp-content/themes/peak-heat/script/global.js
/wp-content/plugins/contact-form-7/jquery.form.js?ver=2.52
/wp-content/themes/peak-heat/style.css
/wp-content/plugins/contact-form-7/scripts.js?ver=3.0
/wp-content/plugins/contact-form-7/styles.css?ver=3.0
/wp-content/plugins/testimonials-widget/testimonials-widget.css

/wp-content/plugins/contact-form-7/styles.css?ver=3.0
/wp-content/plugins/testimonials-widget/testimonials-widget.css
Checking the website URL itself with the online GIDZipTestsite, it confirms that compression is enabled, but when I check the above .css and .js files, it says that they're not compressed.
使用在线 GIDZipTest站点检查网站 URL 本身，它确认已启用压缩，但是当我检查上述 .css 和 .js 文件时，它说它们没有被压缩。
What can I do to include all .css and .js files when compressing my site?
压缩我的网站时，我该怎么做才能包含所有 .css 和 .js 文件？

AddOutputFilterByType DEFLATE text/csssets the compression to deflate, not gzip, so use filesMatchand set the Content-Encodingheader to x-deflate:
AddOutputFilterByType DEFLATE text/css将压缩设置为deflate，而不是gzip，因此使用filesMatch并将Content-Encoding标头设置为x-deflate：
<filesMatch "\.(js|css)$">
Header set Content-Encoding x-deflate
# Header set Content-Encoding compress
# Header set Content-Encoding x-gzip
</filesMatch>
If that fails, uncomment the compressline and comment the x-deflateline. gzip is not part of the standard Apache installation, so install the gzip moduleif deflate is not sufficient. As a last resort, create gzipped versions of your CSS and JS files.
如果失败，请取消注释该compress行并注释该x-deflate行。gzip 不是标准 Apache 安装的一部分，因此如果 deflate 不够用，请安装gzip 模块。作为最后的手段，创建 CSS 和 JS 文件的 gzip 版本。

I think you're missing AddOutputFilterByType DEFLATE text/javascript. Adding that fixed the issue for me.
我想你失踪了AddOutputFilterByType DEFLATE text/javascript。添加它为我解决了这个问题。
