How to use a proxy with mitmproxy

mitmproxy lets you watch and change the traffic of an app you are testing. In upstream mode it passes that traffic on through another proxy, so you can inspect it and change its country at once.

Which proxy works best with mitmproxy?

Any plan with the country you need to test from.

Proxy settings for mitmproxy: host, port and login

A BooProxies plan gives you four things: a host, a port, a username and a password. These are the values for Residential; the username and password are on your plan page.

Hostresi.proxies.boo
HTTP port8080
SOCKS5 port1080
UsernameUSERNAME
Passwordfrom your plan page

The country and the session are chosen in the username, not in a separate setting. The generator on your plan page writes the username for you, and Targeting and sessions explains each part.

mitmproxy proxy setup, step by step

  1. Start mitmproxy in upstream mode with the proxy's address.
  2. Give the login with --upstream-auth.
  3. Point your app or device at mitmproxy as usual.

mitmproxy proxy example

Shell

mitmproxy --mode upstream:http://resi.proxies.boo:8080 --upstream-auth USERNAME:PASSWORD

Replace USERNAME and PASSWORD with the login from your plan page. The example asks an IP-check address, so the output is the address your request left from.

Rotating or sticky sessions for mitmproxy?

If mitmproxy is acting as one visitor through several steps, use a sticky session so the IP address stays the same throughout. If each run is independent, leave the session out and every run starts from a new address.

A sticky username looks like this:

USERNAME-country-us-time-600-session-a1b2c3d4

mitmproxy proxy not working?

  • Your app talks to mitmproxy without a login. Only mitmproxy needs the username and password, which also makes it a handy forwarder for apps that cannot send one.
  • A 407 error means the username or password was not accepted. Copy both again from your plan page, and check that nothing added a space or cut the username short.
  • If the IP address is in the wrong country, look at the username: the country code is part of it. More fixes.
