sshtunnel-requests

Install

$ pip install sshtunnel-requests

Usage

import sshtunnel_requests

requests = sshtunnel_requests.from_url(
    'ssh://username@host:port', '<path>/<to>/private_key')

resp = requests.get('http://httpbin.org/ip')
print(resp.status_code)
# 200
print(resp.json())
# public IP of ssh-server machine

reused created tunnel to request more then once:

import sshtunnel_requests

requests = sshtunnel_requests.from_url(
    'ssh://username@host:port', '<path>/<to>/private_key')

urls = [
    'http://httpbin.org/headers',
    'http://httpbin.org/ip',
    'http://httpbin.org/user-agent',
    'http://httpbin.org/uuid',
]
for url in urls:
    resp = requests.get(url)
    print(resp.json())

thread example:

import sshtunnel_requests

requests = sshtunnel_requests.from_url(
    "ssh://<username>@<ssh server host>[:<port>]",
    "<path>/<to>/<private key>"
)

urls = [
    'http://httpbin.org/headers',
    'http://httpbin.org/ip',
    'http://httpbin.org/user-agent',
    'http://httpbin.org/uuid',
]

        )
        futures.append(f)
    done_iter = as_completed(futures)
    for future in done_iter:
        response = future.result()
        results.append(response.json())

Features

• simply use sshtunnel and requests to request HTTP server in internal networking.
• caching ssh tunnel connection to reused next requests of the same server.
• automatic release connection if the ssh tunnel connection has not been used some time (without any consideration of memory leak and fd leak)
• (thread) concurrent support of the same connection.
