# Proxy list containing entries like

# http://host1:port

# http://username:password@host2:port

# http://host3:port

# 这是存放代理IP列表的位置

PROXY_LIST = '/path/to/proxy/list.txt'

#代理模式

# 0 = Every requests have different proxy

# 1 = Take only one proxy from the list and assign it to every requests

# 2 = Put a custom proxy to use in the settings

PROXY_MODE = 0

#如果使用模式2，将下面解除注释：

#CUSTOM_PROXY = "http://host1:port"

使用方法：

将之前用Python爬到的代理IP列表存储到PROXY_LIST可以找到的位置；

几种PROXY_MODE里，可能0是最常用的；如果有哪个IP是特别稳定的话，应该使用2。
