作用
将http哀求与响应的内容发到kafka的topic,以json的形式发送存储
设置相关
- log_format为自定义设置字段,添加后,默认的哀求响应消息将被覆盖

复制代码
- $开头表现是系统变量
- $http_开头的,表现是从哀求头里获取
- 如果获取字段的内容为空,则不会出如今消息体里
- kafka里存储的消息为以下内容
- {
- "now": "2024-09-10T02:01:22+00:00",
- "route_id": "528226539821597458",
- "api": "/pkulaw-chat-gpt-api-4/6.0.0.0/gpt/writer/ping",
- }
复制代码上面设置,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

复制代码 在log_format的同步添加扩展字段
- 这需要修改kafka-logger的源码了
- 获取user-agent中的操作系统,欣赏器等信息,你可以添加下面的方法
- local function parse_user_agent(user_agent)
- local os, browser, version
- -- 检测操作系统
- if user_agent:find("Windows") then
- os = "Windows"
- elseif user_agent:find("Macintosh") then
- os = "Mac OS"
- elseif user_agent:find("Linux") then
- os = "Linux"
- elseif user_agent:find("Android") then
- os = "Android"
- elseif user_agent:find("iPhone") then
- os = "iOS"
- end
- -- 检测浏览器
- if user_agent:find("Chrome") then
- browser = "Chrome"
- version = user_agent:match("Chrome%/(%d+%.%d+)")
- elseif user_agent:find("Firefox") then
- browser = "Firefox"
- version = user_agent:match("Firefox%/(%d+%.%d+)")
- elseif user_agent:find("Safari") then
- browser = "Safari"
- version = user_agent:match("Version%/(%d+%.%d+)")
- elseif user_agent:find("MSIE") then
- browser = "Internet Explorer"
- version = user_agent:match("MSIE (%d+%.%d+)")
- elseif user_agent:find("Trident") then
- browser = "Internet Explorer"
- version = user_agent:match("rv:(%d+%.%d+)")
- end
- return {
- os = os or "Unknown",
- browser = browser or "Unknown",
- version = version or "Unknown"
- }
- 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- function _M.log(conf, ctx)
- local entry
- if conf.meta_format == "origin" then
- entry = log_util.get_req_original(ctx, conf)
- else
- entry = log_util.get_log_entry(plugin_name, conf, ctx)
- end
- -- 添加扩展字段开始
- local user_agent = ngx.var.http_user_agent
- local info = parse_user_agent(user_agent)
- entry.os = info.os
- entry.browser=info.browser
- entry.version=info.version
- -- 添加扩展字段结束
- if batch_processor_manager:add_entry(conf, entry) then
- return
- end
- ...
