fiddler显示客户端请求时间

本文介绍了如何在Fiddler中自定义规则以显示客户端的请求时间。首先,通过菜单栏选择Rules > Customize Rules打开CustomRules.js文件。接着,简单复制并粘贴相关代码来实现功能。如果遇到因复制错误导致的问题,可以删除C:Users用户名DocumentsFiddler2Scripts文件夹下的CustomRules.js文件,重启Fiddler以恢复默认设置。

2.简单粗暴的复制粘贴

// 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.

	// See http://fiddler2.com/r/?fiddlercolumns for more info

附:因为之前遇到过复制粘贴别人的出现错误的现象,所以如果出错了,且已经保存没办法Ctrl+Z返回的情况下,重置CustomRules.js文件的方法如下:

  1. 去到C:\Users\用户名\Documents\Fiddler2\Scripts文件下删除直接CustomRules.js文件
  2. 然后重启fiddler,该文件自动重置。
<think>我们正在讨论Fiddler中修改请求头后如何重新发送请求的问题。根据引用资料,特别是引用[1]和引用[3],我们可以使用Replay功能来实现。 引用[1]提到了两种方法:一种是打断点模拟HTTP请求(方法一),另一种是解锁并重新提交请求(方法二)。方法二正是我们需要的,因为它允许我们修改请求后重新发送。 引用[3]详细介绍了Replay功能,其中提到“Reissue and verify”(重发并验证)功能,可以重新发送请求并验证结果。 具体步骤如下: 1. 捕获到目标请求后,在会话列表中选择该请求。 2. 在右侧的Inspectors标签页中,切换到Headers选项卡,修改请求头(例如,修改User-Agent、Referer等)。 3. 修改完成后,确保该请求处于“Unlocked for Editing”(解锁编辑)状态(在引用[1]的方法二中提到设置请求为“UnlockFor Editing”)。 4. 右键点击该会话,选择“Replay” -> “Reissue Requests”(或者使用快捷键R,或者使用Replay按钮中的相应选项)。根据引用[3],还可以使用“Reissue and verify”(快捷键V)来重发并验证。 注意:这种方法会重新发送一条新的请求,而不会影响原来的请求(即会生成一个新的会话条目)。 另外,引用[3]还提到了针对特定URL设置断点的方法(使用bpu命令),但我们现在不需要断点,只需要修改后重发。 因此,总结步骤: 1. 捕获请求 2. 修改请求头 3. 使用Replay功能重发(Reissue Requests) 下面我们详细说明每一步:</think>### Fiddler修改请求头后重新发送请求的步骤(使用Replay功能) 在Fiddler中修改请求头后重新发送请求,需通过**Replay功能**实现。以下是详细操作流程: --- #### 1. **捕获并修改请求头** ```mermaid graph LR A[启动Fiddler] --> B[访问目标网页] B --> C[左侧会话列表找到目标请求] C --> D[右侧Inspectors > Headers] D --> E[修改请求头字段] ``` - 在Headers选项卡中直接编辑请求头(如添加`Authorization: Bearer xxx`或修改`User-Agent`) - **关键操作**:右键点击请求 → 选择 `Unlock For Editing`(解锁编辑权限)[^1] --- #### 2. **使用Replay功能重发请求** ```mermaid graph TB F[右键点击修改后的请求] --> G[Replay] G --> H{选择重发模式} H --> I[Reissue Requests<br>普通重发(快捷键R)] H --> J[Reissue and Verify<br>重发并验证(快捷键V)] H --> K[Reissue Sequentially<br>顺序重发] ``` - **普通重发**:生成新会话,背景色不变(用于单次测试)[^3] - **重发并验证**:生成新会话且背景变**黄色**,便于结果对比[^3] - **顺序重发**:批量重发时保持请求顺序 > ⚠️ 注意:修改`Content-Length`或消息体后,需同步更新相关头字段 --- #### 3. **高级技巧:精准定位请求** - **URL过滤重发**: 在Fiddler命令行输入: `bpu https://example.com/api` → 仅拦截该域名的请求[^3] `bpafter https://example.com/api` → 仅拦截该域名的响应 - **批量修改重发**: 1. 按`Ctrl`多选会话 2. 右键 → `Replay` → `Reissue Sequentially` --- #### 4. **验证结果** -请求会出现在会话列表**最顶部** - 对比原始请求和重发请求的: - **状态码**(如200 OK vs 403 Forbidden) - **响应时间** - **返回数据**(在Inspectors > TextView查看) > 示例:修改`User-Agent`为移动端标识后重发,观察服务器返回移动版页面[^1] --- #### 5. **恢复设置** 完成测试后务必执行: - 命令行输入 `bpu` → 清除所有URL断点[^3] - 菜单栏 → `Rules` → `Automatic Breakpoints` → `Disabled` > 💡 提示:使用`Shift+R`可快速重发选中的请求,避免菜单操作 [^1]: 通过Unlock For Editing解锁编辑权限后,使用Replay功能生成新请求 [^3]: 三种重发模式的区别在于结果标识和顺序控制,Reissue and Verify会用黄色背景标记新会话
