    import base64    # 代理服务器
    proxyServer = "http://http-dyn.abuyun.com:9020"
    # 代理隧道验证信息
    proxyUser = "xxxxxx"
    proxyPass = "xxxxxx"
    # for Python2
    proxyAuth = "Basic " + base64.b64encode(proxyUser + ":" + proxyPass)
    # for Python3
    #proxyAuth = "Basic " + base64.urlsafe_b64encode(bytes((proxyUser + ":" + proxyPass), "ascii")).decode("utf8")

    class ProxyMiddleware(object):
        def process_request(self, request, spider):
            request.meta["proxy"] = proxyServer
            request.headers["Proxy-Authorization"] = proxyAuth

request.meta['Proxy'] = 'http-pro.abuyun.com:9010'，在http-pro.abuyun.com:9030前面加上http://就可以了

request.meta['Proxy'] = 'http-pro.abuyun.com:9010'

改成

request.meta['Proxy'] = ',问题解决

```
request.meta['Proxy'] = 'http-pro.abuyun.com:9010'
```
我是把‘proxy'改为'Proxy'后好像可以了
