Mac下也能用抓包工具Fiddler

一直以来都是在Windows底下工作，对于抓包工具，自然而然当属Fiddler最最出色。不过Fiddler是在.Net runtime环境下运行的，所以想要在Mac下使用，有些困难。

在试过了Charles、Rythem、TinyProxy和NProxy这些抓包工具后，我依然苦恼，它们有的需要支付昂贵的费用，有的只支持本机网页请求代理，而有些界面只有文本模式，这让我无法适从。

直到去年10月份(2016年10月)，Telerik官网上悄然地放上了Fiddler的OSX版，这让我欣喜若狂，赶紧来尝试。

环境安装

Mono安装

首先，Mac下需要使用.Net编译后的程序，需要用到跨平台的方案Mono(现阶段微软已推出跨平台的方案.Net Core，不过暂时只支持控制台程序)。安装程序可以从http://www.mono-project.com/download/#download-mac地址下载。

安装完后，在Terminal里执行以下命令：

1	/Library/Frameworks/Mono.framework/Versions/<mono version>/bin/mozroots --import --sync

此步是为了从Mozilla LXR上下载所有受信任的root证书，存于Mono的证书库里。root证书能用于请求https地址。

接下来如果想要运行Fiddler，还需要把Mono加入到环境变量中。编辑.bash_profile文件：

1	sudo vi ~/.bash_profile

加入文本：

1 2	export MONO_HOME=/Library/Frameworks/Mono.framework/Versions/5.0.1 export PATH=$PATH:$MONO_HOME/bin

保存后重新打开Terminal，Mono环境已装好。

Fiddler的安装

从Fiddler官网https://www.telerik.com/download/fiddler下载fiddler-mac.zip的压缩包。解压到非中文字符的路径下。

Fiddler运行

打开Terminal，进入到刚才解压的Fiddler路径，执行命令运行：

1	sudo mono Fiddler.exe

是不是跟Windows下的界面一样好看？

 

如果启动fiddler：sudo mono Fiddler.exe 报错
