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"], );
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") >= ||
option.url.indexOf("/Member/BBB")>= ||
option.url.indexOf("/Member/CCC")>=) {
logRequest = true;
}
if (logRequest) {
//记录请求时间
var costTime = endClientTime - (option.StartClientTime - );
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。
