在使用openResty和lua构建nginx分发层时，遇到set_keepalive错误，报错信息为lua entry thread aborted: bad argument #2 to ‘set_keepalive’ (number expected, got nil)。解决方法包括在lua脚本中添加keepalive=false参数，或者设置keepalive_timeout。经测试，设置keepalive=false的方法更有效。" 60958633,5143179,C语言与串行通信：深入理解串口操作,"['C语言', '串行通信', 'Linux', '通信协议', '串口操作']

看亿级流量详情页，使用nginx+lua搭建nginx的分发层遇到这个问题，
纠结了两天，发现需要设置set_keepalive，两种方法：
（1）在hello.lua脚本中
| local http = require “resty.http”
local httpc = http:new()
local resp, err = httpc:request_uri(backend, {
method = “GET”,
path = requestPath,
