TIPS

• 修改完nginx配置之后，要运行nginx -t检查配置
• lua中的print以notice日志打印到error_log中，所以需要开启notice日志，error_log /var/log/nginx/error.log notice; 参考： http://wiki.nginx.org/HttpLuaModuleZh#print
• body_filter_by_lua可以用于修改响应， ngx.arg[1]为body正文，由于响应可能会分成多段，所以lua代码可能会触发多次，ngx.arg[2]为eof标记，当正文结束时，ngx.arg[2]为true
• 设置lua_code_cache off，可以禁用*_by_lua_file的lua缓存，编辑lua代码之后，不需要reload nginx即可生效，这个指令对于content_by_lua之类写在nginx配置文件内部的lua代码无效。
