关于 WEB/HTTP 调试利器 Fiddler 的一些技巧分享
Fiddler 高级用法：Fiddler Script 与 HTTP 断点调试
2、Fiddler AutoResponder：请求、响应应答与替换
AutoResponder 是 Fiddler 比较重要且比较强大的功能之一。可用于拦截某一请求，并重定向到本地的资源。拦截和重定向后，实际上访问的是本地的文件或者得到的是Fiddler的内置响应。使用Fiddler的内置响应替代服务器的应答。可用于调试服务器端代码而无需修改服务器端的代码和配置
2.1 线上档案替换为本机端档案
右上的AutoResponder ，勾选Enable automatic responses 和Unmatched requests passthrough ，按下右边的Add ；
再将下方的Rule Editor 第一行修改为线上地址（地址也可以使用Regular Expression ，开头加上regex: 即可。）；
按下Rule Editor 第二行右边的箭头，选择Find a file ... ；
选择要替换成的本机端档案，按下右边的SAVE ，大功告成！
CustomRules.js高级应用
更详细的说明请参考Fiddler官方说明文件- Script Samples 。
背景介绍：这个文件可以定制很多东西，都是永久性的设置。如果要临时性的设置，就用左小角的命令。
打开CustomRules.js方法1：脚本文件CustomRules.js位于 Fiddler2\Scripts\CustomRules.js
打开CustomRules.js方法2： 点击菜单Rules->Customize Rules。如果安装了编辑器，就会打开“Fiddler ScriptEditor”编辑界面
打开方法3：
1.2.1 修改session样式
// 修改session中的显示样式（颜色）
oSession["ui-color"] = "orange";
//修改http请求，在如下函数中修改http请求头：
static function OnBeforeRequest(oSession: Session)
//修改http应答，在如下函数中修改http应答：
static function OnBeforeResponse(oSession: Session)
//在如下函数中fiddler命令（右下角的命令行）：
static function OnExecAction(sParams: String[])
//例如http请求中，对域名为p.21kunpeng.com的URI的http请求内容作修改：
if (oSession.host.indexOf("p.21kunpeng.com") > -1) {
// 修改session中的显示样式（颜色）
oSession["ui-color"] = "orange";
// 移除http头部中的MQB-X5-Referer字段
oSession.oRequest.headers.Remove("MQB-X5-Referer");
// 修改http头部中的Cache-Control字段
oSession.oRequest["Cache-Control"] = "no-cache";
// 修改host
oSession.host = "kyfw.12306.cn";
// 修改Origin字段
oSession.oRequest["Origin"] = "https://kyfw.12306.cn";
// 删除所有的cookie
oSession.oRequest.headers.Remove("Cookie");
// 新建cookie
oSession.oRequest.headers.Add("Cookie", "username=yulesyu;");
// 修改Referer字段
oSession.oRequest["Referer"] = "https://kyfw.12306.cn/otsweb/loginAction.do";
// 获取Request中的body字符串
var strBody=oSession.GetRequestBodyAsString();
// 用正则表达式或者replace方法去修改string
strBody=strBody.replace("1111","2222");
// 弹个对话框检查下修改后的body
FiddlerObject.alert(strBody);
// 将修改后的body，重新写回Request中
oSession.utilSetRequestBody(strBody);
}
//例如http应答中，如果含有location并且location中含有字段initQueryUserInfo，则修改为http://p.21kunpeng.com
var location = oSession.oResponse.headers["Location"];
if(oSession.PathAndQuery.indexOf("initQueryUserInfo") != -1)
{
oSession.oResponse.headers["Location"] = "http://p.21kunpeng.com";
}
1.2.2 修改URI
//将请求URI中http协议替换成https协议，例如：
oSession.fullUrl = "https" + oSession.fullUrl.Substring(oSession.fullUrl.IndexOf(':'));
1.2.3 定制菜单
定制rule菜单的子菜单
例如在rule菜单下定义一个修改http头部中的Q-UA字段的子菜单：
// 定义名为Q-UA的子菜单
RulesString("&Q-UA", true);
// 生成Q-UA子菜单的radio选项
RulesStringValue(0,"x5_4.3", "ADRQBX43_GA/420411&X5MTT_3/024200&ADR&346014& U9200 &0&9065&Android4.0.3 &V3")
RulesStringValue(1,"x5_5.0", "ADRQBX50_B1/500620&X5MTT_3/025001&ADR&346014& U9200 &21013&9255&Android4.2.2 &V3")
RulesStringValue(2,"ios4.1", "IQB41_GA/370015&IMTT_3/370015&IPH&406040&iPodTouch4G&50003&8917&V3")
RulesStringValue(3,"ios5.0", "IQB50_GA/500028&IMTT_3/500028&IPH&406040&iPhone4&50001&9219&iOS7.0.4&V3")
RulesStringValue(4,"&Custom...", "%CUSTOM%")
public static var sQUA: String = null;
还需要在OnBeforeRequest函数中加入：
// Q-UA Overrides
if (null != sQUA) {
oSession.oRequest["Q-UA"] = sQUA;
}
定制tool菜单的子菜单
// tool menu
public static ToolsAction("tool menu")
function DoManualYules(){
FiddlerObject.alert("tool menu"); // 根据需要定制
}
定制右键子菜单
// tool menu
public static ContextAction("context menu")
function DoOpenInIE(oSessions: Fiddler.Session[]){
FiddlerObject.alert("context menu"); // 根据需要定制
}

// 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.

配置fiddler到windows自启动测试软件自动升级
Q 怎么把被测软件+fiddler加入到windows的自启动菜单？
A: 开始菜单>自启动右键选“文件夹设置
fiddler左下角命令行的使用 （断点，替换host）
官方文档：https://docs.telerik.com/fiddler/knowledgebase/quickexec
会话列表下边的黑色区域是QuickExec命令行，可以在里面输入命令，回车之后即可执行，非常方便，常用的命令如下：
更详细的说明请参考Fiddler官方说明文件- QuickExec Reference 。
- •help 打开官方的使用页面介绍，所有的命令都会列出来
- •cls 清屏 (Ctrl+x 也可以清屏)
- •?.png 用来选择png后缀的图片
- •bpu截获request ， 命令行输入 go 会断续执行所有中断，再次输入 bpu 会清除所有的断点。
- •bpafter 截获response
- urlreplace www.demo.com www.dev.demo.com 暂行性的替换HTTP Request Host。所有原先发到www.demo.com的HTTP请求 ， Fiddler都帮你转发到www.dev.demo.com ，而在浏览器中毫无感觉。 测试debug过程中常有这种需求。这种是暂时的替换，如果要永久的替换就是去修改CustomRules.js
-
urlreplace 要清除转发，请在同一位置输入urlreplace
-
bpu在请求开始时中断,
-
bpafter在响应到达时中断,
-
bps在特定http状态码时中断,
-
bpv/bpm在特定请求method时中断。
可以发现urlreplace 做的是整个网址字串的取代，所以可以动手脚的地方不只于此。
永久的方法是修改Fiddler的CustomRules.js ，注意是.js ！ 点下Fiddler 上方的Rules ，再点Customize Rules ：
如果有安装FiddlerScript Editor ，会用FiddlerScript Editor开启CustomRules.js ，否则会用笔记本开启。 或者也可以到「我的文件 Fiddler2 Scripts 」直接编辑CustomRules.js 。
请先在CustomRules.js 找到：
static function OnBeforeRequest ( oSession : Session ) {
// ...
}
在函式OnBeforeRequest 中加入：
if ( oSession . HostnameIs ( 'www.demo.com' ) )
oSession . hostname = 'www.dev.demo.com' ;
将CustomRules.js 存档， Fiddler 会自动重新载入CustomRules.js ，原先发到www.demo.com 的HTTP Request 就会自动转发到www.dev.demo.com 。
设置断点
设置断点目的：
1)修改httpRequest：host, cookie或 表单中的数据,模拟异常请求。
2) fiddler 断点截获，模拟接口超时场景
测试场景：前端获取视频列表2s内没返回就会播放在线视频，而不是播放录制的视频列表
目的：使用fiddler拦截前端的请求，不到达服务器，或者是拦截服务器的应答，不传给前端，使得其超过2s播放在线视频，而不是录制视频
设置断点两种方法：
第一种：打开Fiddler 点击Rules-> Automatic Breakpoint ->Before Requests(这种方法会中断所有的会话)，消除断点的方法，点击Rules-> Automatic Breakpoint ->Disabled。
第二种: 在命令行中输入命令: bpu http://www.qq.com，这种方法只会中断http://www.qq.com，消除断点的方法就是在命令行中输入命令 bpu。
但是这两种方法当程序运行到断点处的时候都会停止，需要手动点击“Run to Completion”重新启动，非常不方便。而且通过fiddler的菜单功能，无法修改http请求的URI。此时Fiddler Script的优点就体现出来了，Fiddler Script的本质其实是用JScript.NET语言写的一个脚本文件CustomRules.js，语法类似于C#, 通过修改CustomRules.js可以很容易的修改http的请求和应答，不用中断程序，还可以针对不同的URI做特殊的处理，除此之外还可以根据开发者的需要去定制菜单。
在最底部的位置中添加的了一个为红色的图标。说明断点设置成功了。
请求前断点（before request 快捷键 F11）
方法1） 点击Rules-> Automatic Breakpoint ->Before Requests，这种方法是中断所有的会话，如果想消除断点，点击Rules->Automatic Breakpoint ->Disabled就可以了。
方法2） 在QuickExec命令行中输入：“bpu网址/会话名”，这种方法是中断指定服务器的会话，如果想消除命令，在命令行中输入“bpu”。
设置断点（after response 快捷键alt+f11）
方法1） 点击Rules-> Automatic Breakpoint ->Before Responses，这种方法是中断所有的会话，如果想消除断点，点击Rules->Automatic Breakpoint ->Disabled就可以了。
方法2） 在QuickExec命令行中输入：“bpafter网址/会话名”，这种方法是中断某一具体的会话，如果想消除命令，在命令行中输入“bpafter”。
断点命令介绍：
-
bpu在请求开始时中断,
-
bpafter在响应到达时中断,
-
bps在特定http状态码时中断,
-
bpv/bpm在特定请求method时中断。
提示：命令输入区域输入help，回车执行会打开一页面详细介绍fiddler的所有命令。
也可以在菜单栏设置断点，是针对所有的会话请求，不大实用，建议用命令。
以bpu为例演示断点功能：
（1）以淘宝无线H5为例，在浏览器打开m.taobao.com首页。
（2）在Fiddler命令行输入区输入“bpu”回车执行清掉原有的断点，然后输入“bpu m.taobao.com/search.htm”回车执行，接下来就会中断URL中包含此地址的请求。
（3）在浏览器淘宝首页顶端搜索框输入“充气娃娃”后点击搜索，此时请求被中断，在Fiddler会话列表面板看到以红色小图标开头被中断的会话
（4）点击会话列表中被中断的会话，依次进入Inspectors-->WebForms。此时请求并未发出，q参数即为查询关键字，我们修改为“nike”，然后点击“Break on Response”按钮。注：在这里实现修改了请求数据，其它的post数据，甚至是headers里的cookie、referer、user-agent等都可以修改。
（5）右边面板Response区有响应内容了，这时Fiddler再次中断了response，响应已到达Fiddler代理，但还没返回给浏览器。点击Inspectorsg下Response区的“response is encoded and may need to decoded before inspection.Click here to transform”后，即可在TextView tab看到返回的html内容。在这里修改response中的title部分，然后点击“Run to Completino"把修改后的response返回给浏览器。
（6）回到浏览器，搜索出关键字为“nike”的结果，而不是“充气娃娃”，标题也被修改为“搜索充气娃娃”。
其他：
-
命令行输入 go 会断续执行所有中断，再次输入 bpu 会清除所有的断点。

如上第四点图所示，这里有很多的操作选择，就是选择输出内容，选择之后，实际的响应数据就会这些替代，特别是最后一个find 操作a file：这个我们可以中断一个图片，然后这里选择本地的一张图片，这样我们就可以替换页面的图片。比较强大的场景就是例如现网js出了问题，但是一般现网的js是压缩过的，在firebug中根本无法调试，这样我们可以把它映射到本地的一个原始版本，这样firebug就会拿到一份原始的js，就可以方便的调试了。
