Question

I am using scrapy to crawl website now I need to set proxy handle the request which has been sent. Can anyone help me solve this set proxy in scrapy app. Please give any sample

Answer 1

You can do it through the code below found here:

1 – Create a new file called middlewares.py and save it in your scrapy project and add the following code to it.

# Importing base64 library because we'll need it ONLY
#in case if the proxy we are going to use requires authentication
import base64

# Start your middleware class
class ProxyMiddleware(object):
  # overwrite process request
  def process_request(self, request, spider):
    # Set the location of the proxy
    request.meta['proxy'] = "http://YOUR_PROXY_IP:PORT"

    # Use the following lines if your proxy requires authentication
    proxy_user_pass = "USERNAME:PASSWORD"
    # setup basic authentication for the proxy
    encoded_user_pass = base64.encodestring(proxy_user_pass)
    request.headers['Proxy-Authorization'] = 'Basic ' + encoded_user_pass

2 – Open your project’s configuration file (./project_name/settings.py) and add the following code

DOWNLOADER_MIDDLEWARES = {
'scrapy.contrib.downloadermiddleware.httpproxy.HttpProxyMiddleware': 110,
'project_name.middlewares.ProxyMiddleware': 100,
}

Also, you can use multiple proxies with scrapy. More information can be found here.
