前言
最近接到一个需求，就是在国税局的网页中输入
【发票代码】、【*发票号码】、【*开票日期】、【*开具金额(不含税)】、【*验证码】
然后将此发票进行下载，但是【验证码】真的是拦路虎啊，我也查询了好多大佬的论文，有的是通过JS逆向(我一个小白根本看不懂)，有的是通过打码平台，我自己也注册了一个，确实可以，但是还是对国税局的验证码无效，因为国税局的验证码，有颜色区别，有的不要颜色，如下图，所以打码平台是能全部识别出来，但是无法进行颜色识别
所以我决定当代码执行到这里，就进行 input 手动输入，俗称人工解码，笑死

解决思路
1、目录结构
文件夹：【数据源】：用来存放发票信息
注意：时间格式：如2022-12-12 应写成：20221212
chromedriver.exe：selenium谷歌驱动器
根据自己谷歌版本下载：点我官网下载
2、读取数据源（代码如下）
'''
每一行转成列表，个人习惯
'''
df = pd.read_excel('./数据源/'+os.listdir("./数据源/")[0], sheet_name=0, dtype=str, keep_default_na='')
data = df.values.tolist()
3、selenium驱动浏览器(代码如下)
chrome_options = Options()
chrome_driver = "./chromedriver.exe"
driver = webdriver.Chrome(chrome_driver, chrome_options=chrome_options)
driver.get("https://inv-veri.chinatax.gov.cn/")
4、奉上完整版代码
