(Download Firefox driver geckodriver.exe 2.32 and save it in the python \ py3 installation path) pycharm 2018
(2) download selenium3.14.1 (file-setting-Project: code-projectinterpreder) 3. The installation path set by the following variables in the environment:
JDK
Python3
Firebox
Tesseract-OCR 4. Complete the above configuration to test the simple page. To enter a verification code, you need to download the following plug-ins:
(1). Tesseract-OCR (image recognition plug-in). Images cannot be recognized without this plug-in.
(2) download the pillow image package in pycharm. Ii. pycharm write the following code to run from selenium import WebDriver
Import time
Import pytesseract
From Pil Import image, imageenhance
Driver = WebDriver. Firefox ()

Ran. Crop (box). Save ("D: // Python/picture/2.png ")
#4. Obtain the verification code image and read the verification code
Imagecode = image. Open ("D: // Python/picture/2.png ")
# Imagecode. Load ()
Sharp_img = imageenhance. Contrast (imagecode). Enhance (2.0) # image enhancement, binarization

Sharp_img.load () # contrast enhancement
Time. Sleep (2)
# Print (sharp_img)
Code = pytesseract. image_to_string (sharp_img). Strip () # recognize images
#5. After receiving the verification code, enter it for verification.
