1.实例：

log.lua文件

local cjson = require "cjson.safe"
local logger = require "resty.logger.socket"if not logger.initted() thenlocal ok, err = logger.init {host = "127.0.0.1", --部署时,需要填写logserver服务器ipport = 1234,--部署时,需要填写logserver服务器portsock_type = "tcp",--采用udp传输flush_limit = 1,--1就是时实传输,--drop_limit = 5678, --默认1mb 超过会自动删除timeout = 10000,--超时设置pool_size = 100 --连接池大小}if not ok thenngx.log(ngx.ERR, "failed to initialize the logger: ", err)returnend
endclient_ip = ngx.var.remote_addr
local args = ngx.req.get_post_args(10)
if not args thenngx.say("failed to get post args")return
end
-- ngx.req.read_body()logstr = cjson.encode(args).."\n"local bytes, err = logger.log(logstr)
if err thenngx.log(ngx.ERR, "failed to log message: ", err)return
end

日志阶段的配置文件

server{lua_code_cache on;#lua代码缓存,开发期间为off,上线后改为onlua_need_request_body on;listen 8088;location /v2{content_by_lua_block {ngx.say(1);}log_by_lua_file /Users/guanguan/workspace/lua.api.stream/log.lua;}access_log   /usr/local/openresty/nginx/logs/upgrade_access.log  main;error_log    /usr/local/openresty/nginx/logs/upgrade_error.log  debug;}   

2.stream-lua-nginx-module模块的代码

stream.lua文件

local cjson = require "cjson.safe"
local sock = assert(ngx.req.socket(true))
sock:settimeout(1000)  -- one second timout
local data = sock:receive('*l')
ngx.log(ngx.ERR,"服务端接收数据：",data)

receive有几种方式，读取固定字节数，读取行（*l），读取到所有(到关闭连接)，读取任意数据马上返回(*b,需要patch)，此种还未合并到master分支，需要编译：https://github.com/openresty/stream-lua-nginx-module/pull/33

stream配置文件

性能如下：
