When using OpenResty Limit Req, Set the rate to 200 Burst setting 1, after using WRK stress testing, I calculated that the number of 200 status entries in the access log is less than the rate （ see https://github.com/bingoohuang/blog/issues/209） lua_shared_dict my_limit_req_store 100m; server { listen 8700; default_type text/html; location / { return 200 OK; } location /limit { access_by_lua_block { local limit_req = require "resty.limit.req" -- 限制每秒 200 个请求 (rate)，以及 100 的等待队列 （burst), 超过每次 300，直接拒绝 local rate = tonumber(ngx.var.arg_rate or 200) local burst = tonumber(ngx.var.arg_burst or 100) local lim, err = limit_req.new("my_limit_req_store", rate, burst) if not lim then ngx.log(ngx.ERR, "failed to instantiate a resty.limit.req object: ", err) return ngx.exit(500) end -- 以远端IP为限制 key local delay, excess = lim:incoming(ngx.var.binary_remote_addr, true) if excess == "rejected" then ngx.log(ngx.ERR, "rejected") -- ngx.say, ngx.print 发送消息包，必然要先发送消息头，所以需要提前设置 response status （默认为200） ngx.status = 503 ngx.say("XX delay:", delay, ", rate: ", rate, ", burst: ", burst) return ngx.exit(503) end ngx.say("OK delay: ", delay, ", rate: ", rate, ", burst: ", burst, ", excess: ", excess) return ngx.exit(200) } } } -- This is an automated message from the Apache Git Service.
