建议添加ip代理

[ray0807]

由于存在微博账号登录在不同环境下表现不同的问题（#47）,建议添加ip代理，
以下代码仅供参考：

import re
import requests
import pymysql
import time
import random

class SpiderProxy(object):
    def __init__(self):
        self.req = requests.Session()

                print("{} is valid".format(i))

获取可用代理后可以直接，在get请求中设置代理，亲测有效，由于修改了很多源码，所以暂时不提交requests
