proxy_py README¶
proxy_py is a program which collects proxies, saves them in a database and makes periodically checks. It has a server for getting proxies with nice API(see below).
Where is the documentation?¶
It’s here -> http://proxy-py.readthedocs.io
How to build?¶
1 Clone this repository
git clone https://github.com/DevAlone/proxy_py.git
2 Install requirements
cd proxy_py
pip3 install -r requirements.txt
3 Create settings file
cp config_examples/settings.py proxy_py/settings.py
4 Install postgresql and change database configuration in settings.py file
5 (Optional) Configure alembic
6 Run your application
7 Enjoy!
I’m too lazy. Can I just use it?¶
TODO: update, old version!
Yes, you can download virtualbox image here -> https://drive.google.com/file/d/1oPf6xwOADRH95oZW0vkPr1Uu_iLDe9jc/view?usp=sharing
After downloading check that port forwarding is still working, you need forwarding of 55555 host port to 55555 guest.
How to get proxies?¶
proxy_py has a server, based on aiohttp, which is listening 127.0.0.1:55555 (you can change it in the settings file) and provides proxies. To get proxies you should send the following json request on address http://127.0.0.1:55555/api/v1/ (or other domain if behind reverse proxy):
{
"model": "proxy",
"method": "get",
"order_by": "response_time, uptime"
}
Note: order_by makes the result sorted by one or more fields(separated by comma). You can skip it. The required fields are model and method.
It’s gonna return you the json response like this:
{
"count": 1,
"data": [{
"address": "http://127.0.0.1:8080",
"auth_data": "",
"bad_proxy": false,
"domain": "127.0.0.1",
"last_check_time": 1509466165,
"number_of_bad_checks": 0,
"port": 8080,
"protocol": "http",
"response_time": 461691,
"uptime": 1509460949
}
],
"has_more": false,
"status": "ok",
"status_code": 200
}
Note: All fields except protocol, domain, port, auth_data, checking_period and address CAN be null
Or error if something went wrong:
{
"error_message": "You should specify \"model\"",
"status": "error",
"status_code": 400
}
Note: status_code is also duplicated in HTTP status code
Example using curl:
curl -X POST http://127.0.0.1:55555/api/v1/ -H "Content-Type: application/json" --data '{"model": "proxy", "method": "get"}'
Example using httpie:
http POST http://127.0.0.1:55555/api/v1/ model=proxy method=get
Example using python’s requests library:
import requests
import json
def get_proxies():
result = []
json_data = {
"model": "proxy",
"method": "get",
}
url = "http://127.0.0.1:55555/api/v1/"
response = requests.post(url, json=json_data)
if response.status_code == 200:
response = json.loads(response.text)
for proxy in response["data"]:
result.append(proxy["address"])
else:
# check error here
pass
return result
Example using aiohttp library:
import aiohttp
async def get_proxies():
result = []
json_data = {
"model": "proxy",
"method": "get",
}
url = "http://127.0.0.1:55555/api/v1/"
async with aiohttp.ClientSession() as session:
async with session.post(url, json=json_data) as response:
if response.status == 200:
response = json.loads(await response.text())
for proxy in response["data"]:
result.append(proxy["address"])
else:
# check error here
pass
return result
How to interact with API?¶
Read more about API here -> https://github.com/DevAlone/proxy_py/tree/master/docs/API.md
How to contribute?¶
TODO: write guide about it
How to test it?¶
If you’ve made changes to the code and want to check that you didn’t break anything, just run
py.test
inside virtual environment in proxy_py project directory.
How to deploy on production using supervisor, nginx and postgresql in 8 steps?¶
1 Install supervisor, nginx and postgresql
root@server:~$ apt install supervisor nginx postgresql
2 Create virtual environment and install requirements on it
3 Copy settings.py example:
proxy_py@server:~/proxy_py$ cp config_examples/settings.py proxy_py/
4 create unprivileged user in postgresql database and change database authentication data in settings.py
proxy_py@server:~/proxy_py$ vim proxy_py/settings.py
DATABASE_CONNECTION_KWARGS = {
'database': 'YOUR_POSTGRES_DATABASE',
'user': 'YOUR_POSTGRES_USER',
'password': 'YOUR_POSTGRES_PASSWORD',
# number of simultaneous connections
# 'max_connections': 20,
}
5 Copy supervisor config example and change it for your case
cp /home/proxy_py/proxy_py/config_examples/proxy_py.supervisor.conf /etc/supervisor/conf.d/proxy_py.conf
vim /etc/supervisor/conf.d/proxy_py.conf
6 Copy nginx config example, enable it and change if you need
cp /home/proxy_py/proxy_py/config_examples/proxy_py.nginx.conf /etc/nginx/sites-available/proxy_py
ln -s /etc/nginx/sites-available/proxy_py /etc/nginx/sites-enabled/
vim /etc/nginx/sites-available/proxy_py
7 Restart supervisor and Nginx
supervisorctl reread
supervisorctl update
/etc/init.d/nginx configtest
/etc/init.d/nginx restart
8 Enjoy using it on your server!
What is it depend on?¶
