Mac下也能用抓包工具Fiddler

一直以來都是在Windows底下工做，對於抓包工具，天然而然當屬Fiddler最最出色。不過Fiddler是在.Net runtime環境下運行的，因此想要在Mac下使用，有些困難。

在試過了Charles、Rythem、TinyProxy和NProxy這些抓包工具後，我依然苦惱，它們有的須要支付昂貴的費用，有的只支持本機網頁請求代理，而有些界面只有文本模式，這讓我沒法適從。

直到去年10月份(2016年10月)，Telerik官網上悄然地放上了Fiddler的OSX版，這讓我欣喜若狂，趕忙來嘗試。

環境安裝

Mono安裝

首先，Mac下須要使用.Net編譯後的程序，須要用到跨平臺的方案Mono(現階段微軟已推出跨平臺的方案.Net Core，不過暫時只支持控制檯程序)。安裝程序能夠從http://www.mono-project.com/download/#download-mac地址下載。

安裝完後，在Terminal裏執行如下命令：

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

此步是爲了從Mozilla LXR上下載全部受信任的root證書，存於Mono的證書庫裏。root證書能用於請求https地址。

接下來若是想要運行Fiddler，還須要把Mono加入到環境變量中。編輯.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

保存後從新打開Terminal，Mono環境已裝好。

Fiddler的安裝

從Fiddler官網https://www.telerik.com/download/fiddler下載fiddler-mac.zip的壓縮包。解壓到非中文字符的路徑下。

Fiddler運行

打開Terminal，進入到剛纔解壓的Fiddler路徑，執行命令運行：

1	sudo mono Fiddler.exe

是否是跟Windows下的界面同樣好看？

 

若是啓動fiddler：sudo mono Fiddler.exe 報錯

sudo mono --arch=32 Fiddler.exe
