WAMP环境搭默认并没有开启gzip功能。需要修改apache的配置文件进行开启。

方法如下:
    1. httpd.conf中打开deflate_Module和headers_Module模块 vickiexu.com
    2. httpd.conf中添加:
    <IfModule deflate_module>
        SetOutputFilter DEFLATE
        # Don’t compress images and other
        SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary
        SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
        SetEnvIfNoCase Request_URI .(?:pdf|doc)$ no-gzip dont-vary
        AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css
        AddOutputFilterByType DEFLATE application/x-javascript
    </IfModule>
