Run Project

Local Running

• git clone

git clone git@github.com:evansuner/smartProxyPool.git

• Install requirements

pip3 install -r requirements.txt

• Update Configuration(option)
  setting.py

# API Server Configuration
HOST = "0.0.0.0"               # IP
PORT = 9091                    # Listen port

# Database Configuration
DB_CONN = 'redis://:pwd@127.0.0.1:8888/0'

# ProxyFetcher Configuration
PROXY_FETCHER = [
    "freeProxy01",      # Here is the enabled proxy fetching method name,
    "freeProxy02",      # All fetch methods located in fetcher/proxyFetcher.py
    # ....
]

• Start project

# If you already have the running conditions, you can start it through server_proxy_pool.py。
# The program is divided into: schedule scheduler and server Api service

# start schedule programme and web api server
python3 server_proxy_pool.py schedule &
python3 server_proxy_pool.py server

Docker Running

Usage

• Api start server, http://127.0.0.1:9090:

api	method	Description	params
/	GET	api介绍	None
/get	GET	randomly get an agent	option params: ?type=https filter type is https
/pop	GET	get and remove an agent	option params: ?type=https filter type is https
/all	GET	get all agents	option params: ?type=https filter type is https
/count	GET	view counts of agents	None
/delete	GET	delete agent	?proxy=host:ip

• Using in Spiders
  If these proxies are used in spiders, these APIs need to be wrapped into function calls, example:

import requests

def get_proxy():
    return requests.get('https://127.0.0.1:9090/get/').json()
def delete_proxy(proxy):
    return requests.get(f'https://127.0.0.1:9090/delete?proxy={proxy}')

# your spider code here
def parse():
    """..."""
    retry_count = 5
    proxy = get_proxy().get('proxy')
    while retry_count > 0:
        try:
            content = requests.get('https://www.example.com', proxies={'http':f'http://{proxy}'})
            return content
        except TimeoutError:
            retry_count -= 1
    delete_proxy(proxy)
    return None

Self Configuration for proxy

Although this project provides several free proxy repositories, the quality of free proxies is limited, if the proxies you get from this project are not useful, here provides you a method to add new proxy repos:

1. add a new staticmethod in class ProxyFetcher, this function should use generator(yield) returns a formatted proxy likehost:ip, for example:

class ProxyFetcher:
    """..."""
    ...
    @staticmethod
    def freeProxyCustom1():
        """the function name should not duplicate exist"""
        proxies = ['x.x.x.x:5000','x.x.x.x:5001']
        for proxy in proxies:
            yield proxy

2. update settings config:

PROXY_FETCHER = [
    ...,
    'freeProxyCustom1'
]

Finally, schedule process would use your method to scrapy new proxies.
