go-mitmproxy

简体中文

Mitmproxy implemented with golang. Intercept HTTP & HTTPS requests and responses and modify them.

Features

  • Intercept HTTP & HTTPS requests and responses and modify them on the fly
  • SSL/TLS certificates for interception are generated on the fly
  • Certificates logic compatible with mitmproxy, saved at ~/.mitmproxy. If you used mitmproxy before and installed certificates, then you can use this go-mitmproxy directly
  • Addon mechanism, you can add your functions easily, refer to addon/addon.go
  • Performance advantages
    • Golang's inherent performance advantages
    • Forwarding and parsing HTTPS traffic in process memory without inter-process communication such as tcp port or unix socket
    • Use LRU cache when generating certificates of different domain names to avoid double counting
  • Support Wireshark to analyze traffic through the environment variable SSLKEYLOGFILE
  • Support streaming when uploading/downloading large files
  • Web interface

Install

GO111MODULE=on go get -u github.com/lqqyt2423/go-mitmproxy/cmd/go-mitmproxy

Usage

Startup

go-mitmproxy

After startup, the HTTP proxy address defaults to port 9080, and the web interface defaults to port 9081.

After the first startup, the SSL/TLS certificate will be automatically generated at ~/.mitmproxy/mitmproxy-ca-cert.pem. You can refer to this link to install: About Certificates.
