上面设置，是直接在路由或者全局插件设置中，可以通过apisix-dashboard进行设置，使用log_format对记录的信息进行了设置，我们不建议自定义log_format，由于默认的就是最全的信息
不使用log_format，默认的消息体内容如下

在log_format的同步添加扩展字段

  1. local function parse_user_agent(user_agent)
  2.     local os, browser, version
  4.     -- 检测操作系统
  5.     if user_agent:find("Windows") then
  6.         os = "Windows"
  7.     elseif user_agent:find("Macintosh") then
  8.         os = "Mac OS"
  9.     elseif user_agent:find("Linux") then
  10.         os = "Linux"
  11.     elseif user_agent:find("Android") then
  12.         os = "Android"
  13.     elseif user_agent:find("iPhone") then
  14.         os = "iOS"
  15.     end
  17.     -- 检测浏览器
  18.     if user_agent:find("Chrome") then
  19.         browser = "Chrome"
  20.         version = user_agent:match("Chrome%/(%d+%.%d+)")
  21.     elseif user_agent:find("Firefox") then
  22.         browser = "Firefox"
  23.         version = user_agent:match("Firefox%/(%d+%.%d+)")
  24.     elseif user_agent:find("Safari") then
  25.         browser = "Safari"
  26.         version = user_agent:match("Version%/(%d+%.%d+)")
  27.     elseif user_agent:find("MSIE") then
  28.         browser = "Internet Explorer"
  29.         version = user_agent:match("MSIE (%d+%.%d+)")
  30.     elseif user_agent:find("Trident") then
  31.         browser = "Internet Explorer"
  32.         version = user_agent:match("rv:(%d+%.%d+)")
  33.     end
  35.     return {
  36.         os = os or "Unknown",
  37.         browser = browser or "Unknown",
  38.         version = version or "Unknown"
  39.     }
  40. end
复制代码
在kafka-logger的_M.log(conf, ctx)方法中，添加欣赏器扩展字段
  1. function _M.log(conf, ctx)
  2.     local entry
  3.     if conf.meta_format == "origin" then
  4.         entry = log_util.get_req_original(ctx, conf)
  5.     else
  6.         entry = log_util.get_log_entry(plugin_name, conf, ctx)
  7.     end
  8.     -- 添加扩展字段开始
  9.     local user_agent = ngx.var.http_user_agent
  10.     local info = parse_user_agent(user_agent)
  11.     entry.os = info.os
  12.     entry.browser=info.browser
  13.     entry.version=info.version
  14.     -- 添加扩展字段结束
  15.     if batch_processor_manager:add_entry(conf, entry) then
  16.         return
  17.     end
  18. ...
