手动添加代理的时候可以获取到数据.后来在redis的集合中拿到代理以后就出现了这个问题

def process_request(self, request, spider):
    proxy = str(self.redis_db.srandmember('proxy')).replace('b', '')
    request.meta['proxy'] = proxy

此为打印的代理信息与request.meta
{'download_timeout': 3.0, 'proxy': "'https://116.115.210.140:4326'"}
'https://116.115.210.140:4326' <class 'str'>
