Set proxy To hide your IP address to clear a web page using scrapy

Question

I use scrapy to crawl the website now, I need to set the proxy descriptor of the request that was sent. Can someone help me solve this proxy suite in a scrapy application. Please give a link to the sample, if so. And I need a solution from which IP this request comes from.

Answer 1

You can do this through the code below 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 the project configuration file (./project_name/settings.py) and add the following code

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

Alternatively, you can use multiple proxies with scrapy . Additional information can here .
