二、缓存测试(openresty/1.11.2.1)：
ab -n 100000 -c 100 -k http://127.0.0.1/get_cache_value
1、lua_shared_dict cache_ngx 128m 缓存测试

Openresty提供了lua-resty-limit-traffic模块进行限流，模块实现了limit.conn和limit.req的功能和算法
local limit_req = require "resty.limit.req" local rate = 2 --固定平均速率2r/s local burst = 10 --桶容量 local error_status = 503 local nodelay = false --是否需要不延迟处理 --ngx.say('1111111111111111') -- my_limit_req_store local lim, err = limit_req.new("my_limit_req_store", rate, burst) if not lim then --申请limit_req对象失败 ngx.log(ngx.ERR, "failed to instantiate a resty.limit.req object: ", err) return ngx.exit(500) end --ngx.say("local lim") local key = ngx.var.binary_remote_addr local delay, err = lim:incoming(key, true) if not delay then if err == "rejected" then return ngx.exit(503) end ngx.log(ngx.ERR, "failed to limit req: ", err) return ngx.exit(500) end --ngx.log(ngx.ERR, "failed to limit req_test: ") if delay > 0 then -- 第二个参数(err)保存着超过请求速率的请求数 -- 例如err等于31，意味着当前速率是231 req/sec local excess = err -- 当前请求超过200 req/sec 但小于 300 req/sec -- 因此我们sleep一下，保证速率是200 req/sec，请求延迟处理 ngx.sleep(delay) --非阻塞sleep(秒) end
