写这个小程序的原因很简单，哈哈，我要给支持的明星送花。就是网易星闻下的巨星势力榜，如下图所示（以胡歌为例）：
点击右下角的花朵即可送一朵花，左上角显示当前剩余数量，规则是每两分钟花朵数量恢复成100，每个账号可以一直送。如果仅仅是点击花朵形状可以一直送花的话，是很简单的，关键问题在于它时不时会跳出滑动验证码，如下图所示，这时候就需要解决验证码的问题了，当然了，这部分代码我是参考的别人的。
需要做的准备工作比较多，需要用到的库有selenium、PIL、openCV库，还需要安装Chrome浏览器驱动，具体如何安装我就不详述了。需要注意一下，安装OpenCV大家还是去 https://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv网址下载.whl格式的文件再pip install，不然会像我一样走许多弯路…

c.crack_slider(browser)不过代码仍然有不完善的地方，因为验证码拖动是借鉴的别人的代码，我也没有深入理解，这个验证大概需要拖动两三次才验证成功，不过我觉得已经够用了。还有程序偶尔会报错停止运行，这时候就可以再写一个小程序，监控这个程序有没有挂掉，挂掉的话重新运行该程序即可。监控的程序runner.py如下:
import os
from sys import argv
if __name__ == '__main__':
while os.system('python ' + ' '.join(argv[1:])):
print('Halted by exception, restart')在命令行中输入
python -m runner auto_click.py
便可一直运行啦
虽然感觉写这个小程序的初衷比较幼稚，但是确实也是一种动力，虽然之前并不会爬虫这些东西，现在也还是不太懂，东拼西凑了一些别人的东西，不过好在我把它们组合在一起，也能为我所用。最大的感受就是，不会没关系，总可以学的，不理解也没多大问题，能应用到实际生活中也不错，继续加油吧。
