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。
