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.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,
}
