apache使用gzip压缩

打开http.conf文件,首先开启gzip模块:

1	`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:

开启gzip得到的回送信息
