Openwrt ad implantation prototype construction

By setting up a provioxy proxy server on the vro, the author filters the webpage through it and embeds corresponding ads.

If you don't talk nonsense, go directly to the experiment:

Step 1: Prepare the firmware

Compile openwrt firmware-select Privoxy

Step 2: modify the configuration file

Configure the user. filter, user. Action, and config files.

In the config file, you must specify the listening address and port number.

Inject the advertisement script XXX. js into user. Action

See my script https://gist.github.com/qianguozheng for details

Add filter rules in user. Filter

FILTER: block-weedss|
User. Action
{+filter{block-weeds}}.*

Forward all requests whose target address is port 80 to port 8118
iptables -t nat -A PREROUTING -s 0.0.0.0/0.0.0.0 -p tcp --dport 80 -j REDIRECT --to-ports 8118

Step 3: experience the results
At this time, when you open the web page, you will find that the world is so easy to control, every web page has what you want to see.
