Use Python and WebDriver to extend the automatic processing of sliding verification codes on web pages

Introduction:
With the rapid development of the Internet, in order to ensure the security and user experience of the website, many websites have adopted various form of verification code. Among them, sliding verification code is widely used to verify the authenticity of users. But for testers who use automated testing tools, sliding verification codes have become an insurmountable gap.

However, using Python's selenium library and WebDriver, we can easily extend the automated test script to handle sliding verification codes. This article will introduce how to use Python and WebDriver to realize automated processing of sliding verification codes, and attach corresponding code examples.

1. Install the required libraries and drivers

  1. Install Python
    Enter the Python official website, download and install the Python version suitable for your operating system (Python 3.x is recommended Version).
  2. Install selenium library
    Open a terminal or command prompt and run the following instructions to install the selenium library:

    pip install selenium
  3. Download WebDriver
    WebDriver is a Automated testing tools that can simulate user interaction with browsers. Depending on the type and version of the browser you are using, download the corresponding driver from the WebDriver official website and extract it to the system path or project directory.

2. Basic sliding verification code processing
The following is a basic example using Python and WebDriver to process a simple sliding verification code.

from selenium import webdriver
from time import sleep

# 创建浏览器实例
driver = webdriver.Chrome()  # 根据实际情况选择合适的浏览器

# 打开网页
driver.get('http://example.com')  # 替换为实际的网页地址

# 执行滑动操作
slider = driver.find_element_by_id('slider')  # 替换为具体的滑块元素的定位方式
action = webdriver.ActionChains(driver)
action.click_and_hold(slider).perform()
action.move_by_offset(100, 0).perform()  # 根据实际情况调整偏移量
sleep(2)
action.release().perform()

# 关闭浏览器
driver.quit()

The basic process of the above code is:

  1. Create a browser instance through WebDriver;
  2. Open the web page;
  3. Locate the slider element;
  4. Use the ActionChains class to perform sliding operations;
  5. Close the browser instance.

With the above code, we can easily implement a simple sliding verification code processing.

3. More complex sliding verification code processing
For some more complex sliding verification codes, we may need to simulate more precise sliding operations. Here's a more complex example.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from time import sleep

# 创建浏览器实例
driver = webdriver.Chrome()  # 根据实际情况选择合适的浏览器

# 打开网页
driver.get('http://example.com')  # 替换为实际的网页地址

# 定位滑块元素
wait = WebDriverWait(driver, 10)
slider = wait.until(EC.presence_of_element_located((By.ID, 'slider')))

# 执行滑动操作
action = webdriver.ActionChains(driver)
action.click_and_hold(slider).perform()
action.move_by_offset(100, 0).perform()  # 根据实际情况调整偏移量
sleep(2)
action.release().perform()

# 关闭浏览器
driver.quit()

The above code uses the WebDriverWait class to wait for the appearance of the slider element, and introduces the expected condition module to ensure the accuracy of the positioning of the element.

Conclusion:
Using Python and WebDriver, we can easily extend the automated test script to handle the sliding verification code of the web page. With a basic sliding captcha handling example and a more complex sliding captcha handling example, we learned how to position a slider element and perform a sliding operation. These technologies will facilitate our automated testing work, speed up testing, and improve testing efficiency. Give it a try now!
