问题描述
使用了两种方式记录response日志，但是发现两种日志的数据都是乱码，怀疑是直接记录了内存中的数据，这是什么原因呢？
第一种方式：
采用yexiaobai大神的方式，源地址如下：/blog/yexiaobai/1190000000606867
worker_processes 1;error_log logs/error.log;events { worker_connections 1024;}http { log_format log_req_resp ’$remote_addr - $remote_user [$time_local] ’’'$request' $status $body_bytes_sent ’’'$http_referer' '$http_user_agent' $request_timereq_body:'$request_body' resp_body:'$resp_body'’; server { listen 8088; server_name localhost; access_log /tmp/nginx.resp.access.log log_req_resp; lua_need_request_body on; set $resp_body ''; body_filter_by_lua ’local resp_body = string.sub(ngx.arg[1], 1, 1000)ngx.ctx.buffered = (ngx.ctx.buffered or '') .. resp_bodyif ngx.arg[2] then ngx.var.resp_body = ngx.ctx.bufferedend ’; location / {proxy_pass http://173.194.14.40/; } }}
第二种方式：
location /test { content_by_lua ’-- res = ngx.location.capture('http://173.194.14.57/')local res = ngx.location.capture('/', { share_all_vars = true })file = io.open('/tmp/capture.log', 'a+')file:write(res.body)file:close()-- ngx.var.resp_body = res.bodyngx.print(res_s)’;}location / { proxy_pass http://173.194.14.40/;}
问题解答
回答1：已解决，解决方案：
error_log /tmp/nginx.resp.info.log info;location / { proxy_pass http://vpsea.flvcd.com/; body_filter_by_lua ’ngx.log(ngx.INFO, ngx.arg[1])’;}
