Parse and display http traffic from network device or pcap file. This is a go version of origin pcap-parser, thanks to gopacket project, this tool has simpler code base and is more efficient.
For original python implementation, refer to httpcap on pypi.
Install & Requirement
Build httpdump requires libpcap-dev and cgo enabled.
libpcap
for ubuntu/debian:
sudo apt install libpcap-dev
for centos/redhat/fedora:
sudo yum install libpcap-devel
for osx:
Libpcap and header files should be available in macOS already.
Install
go get github.com/hsiafan/httpdump
Usage
httpdump can read from pcap file, or capture data from network interfaces:
-device string
Capture packet from network device. If is any, capture all interface traffics (default "any")
-file string
Read from pcap file. If not set, will capture data from network device by default
-host string
Filter by request host, using wildcard match(*, ?)
-uri string
Filter by request url path, using wildcard match(*, ?)
-force
Force print unknown content-type http body even if it seems not to be text content
-ip string
Filter by ip, if either source or target ip is matched, the packet will be processed
-level string
Output level, options are: url(only url), header(http headers), all(headers, and textuary http body) (default "header")
-output string
Write result to file [output] instead of stdout
-port uint
Filter by port, if either source or target port is matched, the packet will be processed.
-pretty
Try to format and prettify json content
-status string
Filter by response status code or code range
