下面是内存溢出 jb51.cc 通过网络收集整理的代码片段。
内存溢出小编现在分享给大家,也给大家做个参考。
1.在Scrapy工程下新建“mIDdlewares.py”# importing base64 library because we'll need it ONLY in case if the proxy we are going to use requires authenticationimport base64 # Start your mIDdleware classclass 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#该代码片段来自于: http://www.shareJs.com/codes/python/83092.在项目配置文件里(./project_name/settings.py)添加
DOWNLOADER_MIDDLEWARES = { 'scrapy.contrib.downloadermIDdleware.httpproxy.httpProxyMIDdleware': 110,'project_name.mIDdlewares.ProxyMIDdleware': 100,}只要两步,现在请求就是通过代理的了。测试一下^_^
from scrapy.spIDer import BaseSpIDerfrom scrapy.contrib.spIDers import CrawlSpIDer,Rulefrom scrapy.http import Request class TestSpIDer(CrawlSpIDer): name = "test" domain_name = "whatismyip.com" # The following url is subject to change,you can get the last updated one from here : # http://www.whatismyip.com/faq/automation.asp start_urls = ["http://xujian.info"] def parse(self,response): open('test.HTML','wb').write(response.body)
