Question

Fiddler怎么抓取tcp/udp包，如图，我这个只能抓取http包.

Answer 1

Fiddler官网的介绍：
FiddlerCore is the core proxy engine used by Fiddler to intercept and modify web traffic. You can integrate FiddlerCore into your .NET applications to provide unprecedented functionality.

Fiddler应该只是抓取web数据包的工具，应该不能抓tcp/udp等传输层的包。
我的理解，Fiddler不太熟悉。

想抓取tcp/udp的包，推荐使用wireshark或者tcpdump。
