有时我们希望记录特定的请求头信息和特定的响应头信息，以便能够通过关联请求信息和响应头信息，来实现记录请求和响应的对应关系。这里通过逐步尝试和优化的方式进行尝试。具体包括将需要的请求头和响应头组织到一条日志记录，输出到单独的错误日志文件记录等的配置尝试。

1. 配置转发和日志记录

首先配置记录所有的请求头和响应头信息，记录到error_log指定的文件中。

error_log  logs/error.log  info;log_format  main  '$remote_addr [$request_id] - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';location /ngtest {proxy_pass http://127.0.0.1:8060;header_filter_by_lua 'local reqheaders = ngx.req.get_headers()for key, val in pairs(reqheaders) dongx.log(ngx.INFO, "request:", key, " : ", val)end-- 获取所有响应头local headers = ngx.resp.get_headers()-- 打印所有响应头for key, val in pairs(headers) dongx.log(ngx.INFO, "response:", key, " : ", val)end';}

这里的配置是将请求到本地的 　http://127.0.0.1:8060　地址，并且记录请求头和响应头到日志文件，日志级别为INFO。

 3. postman

通过postman发送http请求。 

2. 日志记录
