我有socks 5代理-〉socks 5：//登录名：密码@ip：端口
我累坏了：

class ProxyMiddleware:
def process_request(self, request, spider):
    # Set the location of the proxy
    request.meta['proxy'] = "http://ip:port"

    proxy_user_pass = "login:password"
    encoded_user_pass = base64.encodestring(proxy_user_pass)
    request.headers['Proxy-Authorization'] = 'Basic ' + encoded_user_pass

中间件：

DOWNLOADER_MIDDLEWARES = {
   'bog_name.middlewares.ProxyMiddleware': 100,
}

Scrapy不使用代理
