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

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)


The quick way:

pip install scrapy_proxies

Or checkout the source and run

python setup.py install


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

    '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'

# 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

# 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)
