Using Python to access Onion network over SOCKS proxy

Tor provides a SOCKS proxy so that you can have any application using the same to connect the Onion network. The default port is 9050. The Tor Browser also provides the same service on port 9150. In this post, we will see how can we use the same SOCKS proxy to access the Internet.

Using Python requests module

I used pipenv to install the dependencies.

$ pipenv install
$ pipenv shell
$ pipenv install requests[socks]

After this, writing the actual code is very simple, we will be doing a GET request to https://httpbin.org to find out our IP address.

import requests

def main():
    proxies = {
            'http': 'socks5h://127.0.0.1:9050',
            'https': 'socks5h://127.0.0.1:9050'
    }
    r = requests.get('https://httpbin.org/get', proxies=proxies)
    print(r.text)


if __name__ == '__main__':
    main()

If you see closely, you will find that I am using socks5h as the protocol, instead of socks5. The request documentation mentions that using socks5h will make sure that DNS resolution happens over the proxy instead of on the client side.

The output of the code looks like below:

$ python usesocks.py 
{
  "args": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.4"
  }, 
  "origin": "137.74.169.241", 
  "url": "https://httpbin.org/get"
}

$ python usesocks.py 
{
  "args": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate", 
    "Connection": "close", 
    "Host": "httpbin.org", 
    "User-Agent": "python-requests/2.18.4"
  }, 
  "origin": "77.247.181.162", 
  "url": "https://httpbin.org/get"
}

Now, you can use the same code to access any standard webservice or access any Onion address.
