Fiddler在HTTP编程过程是不可多得的利器，特别是它使用的是代理方式，能够提供非侵入式的HTTP通信报文编程，在Web接口调试方面很方便。特别是它提供使用JScript .NET方式进行功能拓展，让Web前端调试编程变得很容易
先科普
Fiddler, The free web debugging proxy for any browser, system or platform
百度百科的介绍
Fiddler 是用C#写出来的,它包含一个简单却功能强大的基于JScript .NET 事件脚本子系统，它的灵活性非常棒，可以支持众多的http调试任务，并且能够使用.net框架语言进行扩展。

最近有一个简单的需求，就是使用Fidder把去向特定IP和URL的HTTP请求标注起来，并且保存到指定文件中去。下面是实现的FiddlerScript脚本，供参考
1. 筛选指定条件的请求，在发起前拦截
static function OnBeforeRequest(oSession: Session) {
// 筛选指定条件的请求
if (oSession.HostnameIs("118.145.4.46") &&
oSession.HTTPMethodIs("POST") &&
oSession.uriContains("/member/monitor/customerhold!sum.action")) {
oSession["ui-color"] = "red";
}
}
2.设置菜单栏接口开关
// 菜单栏名称
public static RulesOption("Automatically Dump Summary Data")
var m_AutoDumpSumData: boolean = false;
3.请求完成后，将数据包按时间格式指定文件名并保存
static function OnDone(oSession: Session) {
if (null == Session){
return;
}
// 筛选指定条件的请求
if(m_AutoDumpSumData){
if (oSession.HostnameIs("118.145.4.46") &&
oSession.HTTPMethodIs("POST")){
var dSessionId = oSession.id;
// 时间格式化
var date = new Date();
var month = date.getMonth() + 1;
var strDate = date.getDate();
var strHours = date.getHours();
var strMinutes = date.getMinutes();
var strSeconds = date.getSeconds();
var strMilliSeconds = date.getMilliseconds();
if (month >= 1 && month <= 9) {
month = "0" + month;
}
if (strDate >= 0 && strDate <= 9) {
strDate = "0" + strDate;
}
if (strHours >= 0 && strHours <= 9) {
strHours = "0" + strHours;
}
if (strMinutes >= 0 && strMinutes <= 9) {
strMinutes = "0" + strMinutes;
}
if (strSeconds >= 0 && strSeconds <= 9) {
strSeconds = "0" + strSeconds;
}
if (strMilliSeconds >= 0 && strMilliSeconds <= 9) {
strMilliSeconds = "00" + strMilliSeconds;
}else if(strMilliSeconds >= 10 && strMilliSeconds <= 99){
strMilliSeconds = "0" + strMilliSeconds;
}
var currentdate = date.getFullYear() + month + strDate
+ '_' +strHours + strMinutes + strSeconds + '_'+ strMilliSeconds;
// 保存指定文件名到指定位置
if(oSession.uriContains("/member/monitor/customerhold!sum.action")) {
var outFileName = 'C:/Work/origin/customerhold_sum_' + currentdate +'_'+dSessionId+'.txt';
var parsedFileName = 'C:/Work/parsed/customerhold_sum_' + currentdate +'_'+dSessionId+'.txt';
oSession.SaveResponseBody(outFileName);
// 执行文件处理
System.Diagnostics.Process.Start("C:/Work/parser/Parser.exe",outFileName+" "+parsedFileName);
}
}
}

// INTRODUCTION
//
// Well, hello there!
//
// Don't be scared! :-)
//
// This is the FiddlerScript Rules file, which creates some of the menu commands and
// other features of Fiddler. You can edit this file to modify or add new commands.
//
// The original version of this file is named SampleRules.js and it is in the
// \Program Files\Fiddler\ folder. When Fiddler first runs, it creates a copy named
// CustomRules.js inside your \Documents\Fiddler2\Scripts folder. If you make a
// mistake in editing this file, simply delete the CustomRules.js file and restart
// Fiddler. A fresh copy of the default rules will be created from the original
// sample rules file.
// The best way to edit this file is to install the FiddlerScript Editor, part of
// the free SyntaxEditing addons. Get it here: http://fiddler2.com/r/?SYNTAXVIEWINSTALL
// GLOBALIZATION NOTE: Save this file using UTF-8 Encoding.
