最近项目需要简单记录一下 ajax客户端和服务端处理时间,服务端时间的思路是借用BeginRequest和EndRequest事件,为了不影响现有接口返回的数据格式,因此服务处理时间放在response 的header里面。
BeginRequest += (sender, args) => { HttpContext.Current.Items["ServerStartTime"] = DateTime.Now.Ticks.ToString(); }; EndRequest += (sender, args) => { long ticks = ConvertUtil.ToLong(HttpContext.Current.Items["ServerStartTime"], 0); TimeSpan ts = new TimeSpan(DateTime.Now.Ticks -ticks); HttpContext.Current.Response.Headers.Set("ServerProcessTime", Math.Ceiling(ts.TotalMilliseconds).ToString()); };
客户端在借助beforeSend和complete事件,实现code如下:
$(["get", "post"]).each(function (i, ajaxType) { G[ajaxType] = function (option) { $.ajax({ url: option.url, data: option.data, type: ajaxType, beforeSend: function () { option.StartClientTime = new Date(); }, dataType: "json", cache: option.cache, async: option.async, success: function (d) { alert(d) }, complete: function (XMLHttpRequest, textStatus) { var endClientTime = new Date(); try { var logRequest = false; if (option.url.indexOf("/Member/AAA") >= 0 || option.url.indexOf("/Member/BBB")>=0 || option.url.indexOf("/Member/CCC")>=0) { logRequest = true; } if (logRequest) { //记录请求时间 var costTime = endClientTime - (option.StartClientTime - 0); var serverTime = XMLHttpRequest.getResponseHeader("ServerProcessTime"); console.log("Rquest " + option.url + " totlal cost time:" + costTime + " Server time:" + serverTime); var logdata = { ajaxUrl: option.url, TotalTicks: costTime, ServerTicks: serverTime }; $.post("/xxx/LogRequest", logdata); } } catch (e) { } } }); }; });
最后在调用LogRequest把时间记录到日志系统中。
