在setting.py同级目录新建一个middlewares.py

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"

然后再setting.py中添加

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

即可
