======使用方法 1：==============================================================================

下面写怎么使用

#写入全新的文件  （方法里面定义了新的文件名称）new_file(get_top_info(),backend_info(),frontend_info(),listen_info())

结果如下 test.conf

======使用方法 2：=============================================================================

修改acl

增加

fronted_name="ptone"acl_name='web_qq'acl_domain='test.qq.com'acl_backend='ptone-datadeck'new_backend_info=update_fronted_acl(fronted_name,acl_name,acl_domain,acl_backend)new_file(get_top_info(),backend_info(),new_backend_info,listen_info())

结果如下

frontend ptone    bind 10.1.3.222:80    mode http    log global    acl datadeck_qq_com hdr(host) -i datadeck.qq.com use_backend ptone-datadeck if datadeck_qq_com    acl ptoneauth_qq_com hdr(host) -i ptoneauth.qq.com use_backend ptone-auth if ptoneauth_qq_com    acl web_qq hdr(host) -i test.qq.com use_backend ptone-datadeck if web_qqfrontend http-in    bind 220.248.107.234:80    mode http    log global    acl u_8 hdr_end(host) -i u8.qq.com use_backend u8.qq.com if u_8    acl paycbm hdr_end(host) -i paycbm.qq.com use_backend paycbm.qq.com if paycbm

修改

结果如下
