pywin32介绍
1. pywin32从驱动层模拟键盘鼠标的输入！
比如我们打算写一个 某银行网银登陆 的爬虫，因为该银行网站的ActiveX控件的限制，只能在win环境下使用ie浏览器，简单测试代码如下
# 这是错误示例
from selenium import webdriver
class Loginer(object):
def __init__(self, username):
self.username = username
iedriver = '.\IEDriverServer.exe' # iedriver路径
self.driver = webdriver.Ie(iedriver)
self.driver.delete_all_cookies()
self.driver.get('https://perbank.abchina.com/EbankSite/startup.do')
def input_name(self):
input('准备输入用户名！')
self.driver.find_element_by_id('username').send_keys(self.username)
if __name__ == '__main__':
username = 'testlogin'
login = Loginer(username)
login.input_name()
现象：各种报错！无论是否加载控件都不能输入账号！ 短时间又搞不定activeX加密控件！网站有高级反爬，这就是那剩下5%的网站其中之一！此时我们怎么办呢？
看这个文件！input_key.py我们可以从驱动层模拟鼠标键盘的动作！
注意：
1.需要手动调整ie浏览器的位置或调整代码中的坐标参数
2.被selenium控制的ie浏览器必须调整为100%大小比例

# 100 350是坐标参数，需要调整！
t4('aaa', 100, 350) # 在这里进行测试输出位置！
打开ie浏览器某网银登陆界面，只要不断的调试函数中的X,Y坐标和IE浏览器的位置就可以进行模拟输入进而登陆！
2. 注意 pip install pywin32安装之后 是这样的三个包：
import win32api
import win32con
import win32gui
3. pywin32的搜索关键词
上边的那个只是初步的解决方案！更完美的解决方法我们需要了解几个关键词！
句柄
外挂
后台
可以通过pywein32包拿到ie浏览器的句柄，就可以随时获取ie的坐标，这样就不怕浏览器的位置发生改变了，也就不需要调整ie浏览器的位置，更不需要调整xy坐标参数了！ 并且我们可以用pywin32包控制鼠标键盘的动作为后台运行，这样就不影响鼠标键盘的正常使用了
