tengine定制加上lua tengine-2.3.3 版本 cjson使用，


tengine定制加上lua tengine-2.3.3 版本

简洁

因为需要tengine的特定功能，也需要lua进行一些定制开发，结合两个功能，需要编译支持lua的版本的tengine

各个软件依赖版本

软件版本号备注
systemcentos7.4系统
jemalloc5.3.0jemalloc是tengine用于内存管理的插件
luajit2.1使用openrestry库里面luajit2
lua-nginx-module0.10.21

其他可以增加lua中mysql redis kafka之类模块进行使用

使用cjson

cc -c -O3 -Wall -pedantic -DNDEBUG  -I/usr/local/luajit/include/luajit-2.1/ -fpic -o lua_cjson.o lua_cjson.c
make
make install

json.lua

local cjson = require("cjson");
--数据响应类型JSON
ngx.header.content_type="application/json;charset=utf8"
--定义响应数据
local response = {}
response["code"]=200
response["message"]="SUCCESS"
ngx.say(cjson.encode(response))

location /json {
             content_by_lua_file lua/json.lua;
}
