python ddddocr 进行文字+数字验证码识别

一、python版本

将自动安装符合自己电脑环境的最新 ddddocr。Python 环境需要小于等于 3.9。

pip install ddddocr

  

二、字母数字验证码

代码如下:

原始图片

python ddddocr 进行文字+数字验证码识别

 

 

import ddddocr

ocr = ddddocr.DdddOcr()
with open('111.png','rb') as f:
img_bytes = f.read()

res = ocr.classification(img_bytes)
print(res)

  执行结果

 三、完整登录一个带验证码系统的代码

from selenium import webdriver
from helium import *
import base64
import time
import ddddocr
def open_chrome():
options = webdriver.ChromeOptions()
options.add_argument('--no-sandbox')
# options.add_argument('--proxy-server=socks5://127.0.0.1:1080')
options.add_experimental_option('useAutomationExtension', False)
options.add_experimental_option('excludeSwitches', ['enable-automation'])
driver = webdriver.Chrome(chrome_options=options)
driver.maximize_window()

set_driver(driver)
go_to("http://127.0.0.1:8000/login/")
write("admin","账号")
write("admin","密码")
code_base64 = driver.find_element_by_css_selector("#code + img").get_attribute('src').split("data:image/png;base64,")[-1]
img = base64.b64decode(code_base64)
# 识别验证码
ocr = ddddocr.DdddOcr(show_ad=False)
code = ocr.classification(img)
# code = res['pic_str']
write(code, '验证码')
time.sleep(3)
click(Button('登 录'))
driver.get_screenshot_as_file("test.png")


time.sleep(5)
kill_browser()
if __name__ == '__main__':
open_chrome()
