Python基于scrapy采集数据时使用代理服务器的方法
本文实例讲述了Python基于scrapy采集数据时使用代理服务器的方法。分享给大家供大家参考。具体如下：
# To authenticate the proxy, #you must set the Proxy-Authorization header. #You *cannot* use the form http://user:pass@proxy:port #in request.meta['proxy'] import base64 proxy_ip_port = "123.456.789.10:8888" proxy_user_pass = "awesome:dude" request = Request(url, callback=self.parse) # Set the location of the proxy request.meta['proxy'] = "http://%s" % proxy_ip_port # setup basic authentication for the proxy encoded_user_pass=base64.encodestring(proxy_user_pass) request.headers['Proxy-Authorization'] = 'Basic ' + encoded_user_pass
希望本文所述对大家的python程序设计有所帮助。
