验证码思路
pip install Pillow
pip install pytesseract
driver.save_screenshot(“E:/123.png”)
code_elemnet=driver.find_element_by_id(“getcode_num”)
print(code_elemnet.location)
left=code_elemnet.location[‘x’]
top=code_elemnet.location[‘y’]
right=code_elemnet.size[‘width’]+left
height=code_elemnet.size[‘height’]+top
im=Image.open(“E:/123.png”)
img = im.crop((left,top,right,height))
img.save(“E:/666.png”)
文本大小要改成100%

windows安装tesseract-ocr 下载地址:链接：https://pan.baidu.com/s/1E1hBscSfjapEUqwrcEQFSQ 提取码：tlrz

github地址: https://github.com/tesseract-ocr/tesseract

You can either Install Tesseract via pre-built binary package or build it from source.

windows:

The latest installer can be downloaded here: http://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-setup-3.05.01.exe and http://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-setup-4.00.00dev.exe (experimental).

加入系统的path环境变量

出现这个报错
FileNotFoundError: [WinError 2] 系统找不到指定的文件。

修改pytesseract.py文件里的tesseract_cmd

tesseract_cmd = ‘C:\Program Files\Tesseract-OCR\tesseract.exe’

下载的默认训练集也没有添加到系统路径,会报错pytesseract.pytesseract.TesseractError: (1, ‘Error opening data file \Program Files (x86)\Tesseract-OCR\tessdata/chi_sim.traineddata’)

解决方法：
设置环境变量 TESSDATA_PREFIX
C:\Program Files (x86)\Tesseract-OCR\tessdata

重启下pycharm，或者重启下电脑，我试了下 还是可以的
