安装图形化支持依赖：

pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple

代码如下：

import requests

        self.session = requests.Session()
        self.response = self.session.get(self.login_url,headers=self.headers)
    def getVerifyCode(self):

        print(verifyCode_url)
        image = io.imread(verifyCode_url)
