GET方式

local id = tostring(ngx.var.arg_id)
local type = tostring(ngx.var.arg_type)

POST方式

ngx.req.read_body()
local args = ngx.req.get_post_args()
local id = tostring(args["id"])
local type = tostring(args["type"])

两种方式混合

local request_method = ngx.var.request_method
local args = nil
if "GET" == request_method then
    nginx.say("Get")
    args = ngx.req.get_uri_args()
else
    nginx.say("Post")
    ngx.req.read_body()
    args = ngx.req.get_post_args()
end

local id = tostring(args["id"])
local type = tostring(args["type"])

IP地址

local ip_addr = ngx.var.remote_addr

当前时间

os.date("%Y-%m-%d %H:%M:%S")

os.time()

响应

-- 设置响应头信息
ngx.header["Content-Type"] = "application/json;charset=UTF-8"
-- 获取Lua版本号
ngx.header["X-Powered-By"] = _VERSION
ngx.status = ngx.HTTP_OK
-- 内容输出
ngx.say(cjson.encode(resp))
-- 设置响应状态码
ngx.exit(ngx.HTTP_OK)
