fiddler常用功能一、AutoResponder  代理二、Willow 轉發三、Rules 規則實作指定傳回

一、AutoResponder  代理

1、增加規則,打開功能

fiddler常用功能一、AutoResponder  代理二、Willow 轉發三、Rules 規則實作指定傳回

2、配置規則

常用到這兩種

1)url代理,轉發到新的域名,如下圖

其中$後面跟的數字表示填入正則中比對位置,2表示填入第個位置比對的資料

2)代理指定檔案

檔案内容為接口傳回的接口,可以構造指定傳回資料包

配置完别忘了點選save,勾選規則,才能生效

二、Willow 轉發

1、需要下載下傳willow插件

打開開關生效

2、建規則

先建project,project下可建rule、host、exten三種,常用host和exten

2)指定比對url的ip

三、Rules 規則實作指定傳回

1、需要編寫js腳本

2、完成規則編寫後可以在這裡使用,勾選則使用

3、如何編寫

檔案目錄位于 C:\Users\XXX\Documents\Fiddler2\Scripts

以下為新增的規則

// 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.
