打开http.conf文件,首先开启gzip模块:
LoadModule deflate_module modules/mod_deflate.so
然后,配置何时使用gzip压缩
<IfModule mod_deflate.c>
# 压缩等级 9
DeflateCompressionLevel 9
# 压缩类型 html、xml、php、css、js
SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/plain text/xml application/x-javascript application/x-httpd-php
AddOutputFilter DEFLATE js css
</IfModule>
重启apache进行测试
测试代码如下:
1 <html> 2 <body> 3 </body> 4 <div id="div1">1234</div> 5 <input type="button" value="ajax请求php页面" onclick="display()" /> 6 <script src="./js/zepto.min.js" type="text/javascript" charset="utf-8"></script> 7 <script type="text/javascript" charset="utf-8"> 8 function display() 9 { 10 $.ajax( 11 { 12 type:"post", 13 url:"newfile.php", 14 data:"des=hello", 15 success:function(msg){alert(msg);} 16 } 17 ); 18 } 19 </script> 20 </body> 21 </html>
未开启:gzip情况下zepto.min.js回送的信息如下:
