中文点选识别

测试网站：https://www.geetest.com/adaptive-captcha-demo

1. 开始验证

# 1.打开首页
driver.get('https://www.geetest.com/adaptive-captcha-demo')

# 2.点击【文字点选验证】
tag = WebDriverWait(driver, 30, 0.5).until(lambda dv: dv.find_element(
    By.XPATH,
    '//*[@id="gt-showZh-mobile"]/div/section/div/div[2]/div[1]/div[2]/div[3]/div[4]'
))
tag.click()

# 3.点击开始验证
tag = WebDriverWait(driver, 30, 0.5).until(lambda dv: dv.find_element(
    By.CLASS_NAME,
    'geetest_btn_click'
))
tag.click()

time.sleep(5)

2. 获取图片

# 要识别的目标图片
parent = driver.find_element(By.CLASS_NAME, 'geetest_ques_back')
tag_list = parent.find_elements(By.TAG_NAME, "img")

3. 目标文字识别

target_word_list = []
for tag in tag_list:
    ocr = ddddocr.DdddOcr(show_ad=False)
    word = ocr.classification(tag.screenshot_as_png)
    target_word_list.append(word)

print("要识别的文字：", target_word_list)

4. 背景坐标识别

import base64
import requests

res = requests.post(
    url='http://upload.chaojiying.net/Upload/Processing.php',
    data={
   
        'user': "自己的用户名",
        'pass': "自己的密码",
        'codetype': "9501",
        'file_base64': base64.b64encode(content)
    },
    headers={
   
        'Connection': 'Keep-Alive',
        'User-Agent': 'Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)',
    }
)

res_dict = res.json()
print(res_dict)

结果：

将结果封装成字典，方便后续找到相应的字并点击

bg_word_dict = {
   }
for item in res_dict["pic_str"].split("|"):
    word, x, y = item.split(",")
    bg_word_dict[word] = (x, y)
print(bg_word_dict)

5. 坐标点击

根据坐标，在验证码上进行点击。

# 8.点击
from selenium.webdriver import ActionChains

for word in target_word_list:
    time.sleep(0.5)
    group = bg_word_dict.get(word)
    if not group:
        continue
        x, y = group
        x = int(x) - int(bg_tag.size['width'] / 2)
        y = int(y) - int(bg_tag.size['height'] / 2)  # 超级鹰获取到的坐标原点为图片左上角，而我们需要的坐标原点为图片中心，所以需要进行转换。
        ActionChains(driver).move_to_element_with_offset(bg_tag, xoffset=x, yoffset=y).click().perform()
        time.sleep(1000)
        driver.close()

结果：
