Scrapy Proxies: random proxy middleware for Scrapy(support load proxies from IPProxyTool)

Random proxy middleware for Scrapy (http://scrapy.org/)

base on https://github.com/aivarsk/scrapy-proxies , support load proxies from https://github.com/qiyeboy/IPProxyPool

Processes Scrapy requests using a random proxy from list to avoid IP ban and improve crawling speed.

Get your proxy list from sites like http://www.hidemyass.com/ (copy-paste into text file and reformat to http://host:port format)

Install

The quick way:

pip install scrapy-proxies-tool

Or checkout the source and run

  python setup.py install

settings.py

  # Retry many times since proxies often fail
  RETRY_TIMES = 10
  # Retry on most error codes since proxies fail for different reasons
  RETRY_HTTP_CODES = [500, 503, 504, 400, 403, 404, 408]

  DOWNLOADER_MIDDLEWARES = {
    'scrapy.downloadermiddlewares.retry.RetryMiddleware': 90,
    'scrapy_proxies.RandomProxy': 100,
    'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 110,
  }

  # Proxy list containing entries like
  # http://host1:port
  # http://username:password@host2:port
  # http://host3:port
  # ...
  PROXY_LIST = ['/path/to/proxy/list.txt']

  # if PROXY_FROM_PROXIES_SERVER = True , proxy_list is server address (ref https://github.com/qiyeboy/IPProxyPool and https://github.com/awolfly9/IPProxyTool )
  # Only support http(ref https://github.com/qiyeboy/IPProxyPool#%E5%8F%82%E6%95%B0)
  # PROXY_LIST = ['http://localhost:8000?protocol=0']

  # disable proxy settings and  use real ip when all proxies are unusable
  PROXY_USE_REAL_WHEN_EMPTY = False
  PROXY_FROM_PROXIES_SERVER = False
  
  # Proxy mode
  # 0 = Every requests have different proxy
  # 1 = Take only one proxy from the list and assign it to every requests
  # 2 = Put a custom proxy to use in the settings
  PROXY_MODE = 0
  
  # If proxy mode is 2 uncomment this sentence :
  #CUSTOM_PROXY = "http://host1:port"

For older versions of Scrapy (before 1.0.0) you have to use scrapy.contrib.downloadermiddleware.retry.RetryMiddleware and scrapy.contrib.downloadermiddleware.httpproxy.HttpProxyMiddleware middlewares instead.

Your spider

In each callback ensure that proxy /really/ returned your target page by checking for site logo or some other significant element. If not - retry request with dont_filter=True

  if not hxs.select('//get/site/logo'):
    yield Request(url=response.url, dont_filter=True)
