1.content_by_lua_block作用:在http内容处理阶段生成数据
server { listen 80; server_name www.a.com; charset koi8-r; location = /test { default_type 'text/plain'; -- content_by_lua_block 执行阶段 content_by_lua_block { ngx.say("hello world") } } }
2.json解释库 -- cjson
location = /test1 { content_by_lua_block { local cjson = require "cjson" ngx.say(cjson.encode{a=1,b=2,c=3}) } }
3.HTTP执行阶段
NGX_HTTP_ACCESS_PHASE 在请求前设置对资源的控制
NGX_HTTP_CONTENT_PHASE 处理HTTP请求内容的阶段,一半会和后端服务器进行交互
4. 参考: https://blog.csdn.net/forezp/article/details/78616660 获取请求类型
location /lua_request{ default_type 'text/html'; lua_code_cache off; content_by_lua_file /usr/example/lua/lua_request.lua; } ———————————————— local arg = ngx.req.get_uri_args() for k,v in pairs(arg) do ngx.say("[GET ] key:", k, " v:", v) end ngx.req.read_body() -- 解析 body 参数之前一定要先读取 body local arg = ngx.req.get_post_args() for k,v in pairs(arg) do ngx.say("[POST] key:", k, " v:", v) end ————————————————
