【问题描述】：

我在我的网站中添加了以下代码以启用 GZIP 压缩，但是当我测试我的 webpage 时，它仍然在在线 GTCompression 测试网站上给我以下错误消息。请告诉我是否还需要在我的 HTML 文件中添加任何内容？

Web Page        The http server hasn't sent out a "Content-Encoding" header.
Your Browser    Your browser is accepting compressed content.

.htaccess 文件

    <ifModule mod_gzip.c>
         mod_gzip_on Yes
         mod_gzip_dechunk Yes
         mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
         mod_gzip_item_include handler ^cgi-script$
         mod_gzip_item_include mime ^text/.*
         mod_gzip_item_include mime ^application/x-javascript.*
         mod_gzip_item_exclude mime ^image/.*
         mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
         </ifModule>

【解决方案1】：

您需要将以下行添加到您的 .htaccess 文件中：

<IfModule mod_deflate.c>
  # Compress HTML, CSS, JavaScript, Text, XML and fonts
  AddOutputFilterByType DEFLATE application/javascript
  AddOutputFilterByType DEFLATE application/rss+xml
  AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
  AddOutputFilterByType DEFLATE application/x-font
  AddOutputFilterByType DEFLATE application/x-font-opentype
  AddOutputFilterByType DEFLATE application/x-font-otf
  AddOutputFilterByType DEFLATE application/x-font-truetype
  AddOutputFilterByType DEFLATE application/x-font-ttf

  AddOutputFilterByType DEFLATE image/svg+xml
  AddOutputFilterByType DEFLATE image/x-icon
  AddOutputFilterByType DEFLATE text/css
  AddOutputFilterByType DEFLATE text/html
  AddOutputFilterByType DEFLATE text/javascript
  AddOutputFilterByType DEFLATE text/plain
  AddOutputFilterByType DEFLATE text/xml

  # Remove browser bugs (only needed for really old browsers)
  BrowserMatch ^Mozilla/4 gzip-only-text/html
  BrowserMatch ^Mozilla/4\.0[678] no-gzip
  BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
  Header append Vary User-Agent
</IfModule>

非常感谢，现在它说 GZIP 已启用 :)

试试下面的代码

<IfModule mod_deflate.c>
          # force deflate for mangled headers
          # 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>

此代码正在阻止我的网站打开。添加上述代码后，我收到以下错误消息。 ` 内部服务器错误服务器遇到内部错误或配置错误，无法完成您的请求。`
那么你的 Apache 服务器没有安装和运行 mod_filter、mod_deflate、mod_headers 和 mod_setenvif 模块
