Gzip 压缩和利用浏览器缓存不适用于我的商店

Question

我正在尝试优化我的商店，我在我的 .htaccess 文件中添加了 Gzip 代码和杠杆浏览器缓存代码：

# Leverage browser caching using mod_expires #
<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/gif "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType application/pdf "access plus 1 month"
    ExpiresByType text/x-javascript "access plus 1 month"
    ExpiresByType application/x-shockwave-flash "access plus 1 month"
    ExpiresByType image/x-icon "access plus 1 year"
    ExpiresDefault "access plus 2 days"
</IfModule>
# End of Leverage browser caching using mod_expires #

# Leverage browser caching using mod_headers #
<IfModule mod_headers.c>
    <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
        Header set Expires "Wed, 15 Apr 2020 20:00:00 GMT"
        Header set Cache-Control "public"
    </FilesMatch>
</IfModule>
# End of Leverage browser caching using mod_headers #

Answer 1

这里是GZIP压缩的代码

<ifModule mod_deflate.c>

   SetOutputFilter DEFLATE
   AddOutputFilterByType DEFLATE text/html text/css text/plain text/xml application/x-javascript application/x-httpd-php
   BrowserMatch ^Mozilla/4 gzip-only-text/html
   BrowserMatch ^Mozilla/4\.0[678] no-gzip
   BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
   BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
   SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip
   Header append Vary User-Agent env=!dont-vary
</ifModule>

<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>

对于杠杆浏览器缓存，您的代码是正确的，但如果它不起作用，那么您必须检查服务器上是否启用了 mod_expires 和 mod_headers 模块。

Answer 2

启用 Apache mod_headers 和 mod_expires 模块

Please check mod_expires and mod_headers are enable or not on your store through the below code.

<?php phpinfo();?>

If both extension not unable to your server,please follow following steps:-

第 1 步：-

Now login to server using SSH console and continue below steps:

启用mod_headers:

sudo a2enmod headers

启用mod_expires:

sudo a2enmod expires

Step 2 :-

after completing the server update, you need to restart Apache server to make these changes effective. Enter below line in your SSH console to restart Apache.

service apache2 restart

Or else reboot your server by following code in SSH:

reboot

在您的 .htaccess 文件中使用以下代码。

<IfModule mod_headers.c>
     # YEAR
     <FilesMatch "\.(ico|gif|jpg|jpeg|png|flv|pdf)$">
          Header set Cache-Control "max-age=29030400"
     </FilesMatch>
     # WEEK
     <FilesMatch "\.(js|css|swf|woff)$">
         Header set Cache-Control "max-age=604800"
     </FilesMatch>
     # 45 MIN
     <FilesMatch "\.(html|htm|txt)$">
        Header set Cache-Control "max-age=86400"
     </FilesMatch>

     Header set Connection keep-alive

</IfModule>

<ifModule mod_gzip.c>
    mod_gzip_on Yes
    mod_gzip_dechunk Yes
    mod_gzip_item_include file \.(html?|txt|css|js|php|pl|asp|html)$
    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>

<ifmodule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</ifmodule>

清除商店缓存并重新加载网站后 URL，重新检查 gtmetrix 工具或任何您正在使用的工具。
