实战题目

使用python+selenium实现输入验证码的UI自动化。登录页面如图：

解题方案

验证码登录需要导入相关模块和库，本文使用的是opencv和ddddocr模块组合，导入方式采用pip3 install opencv-python、pip3 install ddddocr，成功安装即可。

代码：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
from common import do_time
import os
from time import sleep
import ddddocr

# 设置浏览器
option = webdriver.ChromeOptions()
option.add_experimental_option("prefs", {
    "download.prompt_for_download": False,
    "download.directory_upgrade": True,
    "safebrowsing.enabled": True,
    "credentials_enable_service": False,
    "profile.password_manager_enabled": False
})  #初始化Chrome的时候，不弹出密码框
option.add_experimental_option('excludeSwitches', ['enable-automation'])  #设置防止被检测为selenium
option.binary_location = r'D:\Software\Google\Chrome\Application\chrome.exe'
# 启动Chrome浏览器
driver = webdriver.Chrome(service=Service("../config/chromedriver.exe"), options=option)
driver.maximize_window()
driver.implicitly_wait(10)

# 打开登录网页
driver.get("https://sso-iot-uat.dianliantech.com/oauth/login")
sleep(3)
# 输入用户名和密码
driver.find_element(By.XPATH, '//*[@id="username"]').send_keys('username')
driver.find_element(By.XPATH, '//*[@id="password"]').send_keys('password')

# 验证码处理
# 找到验证码并将验证码以截图的方式保存
vcode_ele = driver.find_element('xpath', '//*[@id="verifyImg"]')
vcode_path = r'D:\Learn\pycharmProject\IOT\vcode\vcode.png'     #定义保存路径
vcode_ele.screenshot(vcode_path)   #截图保存至指定路径下

# 调用ddddocr框架，读取验证码，并填入输入框
ocr = ddddocr.DdddOcr()
with open(vcode_path, 'rb') as f:
    img_bytes = f.read()
vcode = ocr.classification(img_bytes)
driver.find_element(By.XPATH, '//*[@id="verifyCode"]').send_keys(vcode)

# 点击登录按钮
driver.find_element(By.XPATH, '//*[@id="loginSubmit"]').click()
