多缺口滑块验证demo

环境

• win10

• Python3.9

分享一下项目中碰到的一个多缺口滑块验证，先触发一下滑块抓包分析一下是用的哪一家滑块 经过分析发现不是用的顶象或数美，验证图片的接口地址是他自己的的一个接口，应该是自己写的验证，往有经验的大佬指点下。 抓到滑块图片地址，是经过加密的，通过canvas绘画至页面，始终没有找到真实的url，用最笨的方法直接在页面截图

def get_v3(self):

新开一个窗口，通过执行js来新开一个窗口（有奇效，可以不被检测到）

js = 'window.open(“ self.driver.execute_script(js)

切换窗口

self.driver.switch_to.window(self.driver.window_handles[1])
IMEI = “862056063123458”

定位输入框

phone_IMEI = self.wait.until(EC.presence_of_element_located((By.XPATH, ‘//*[@id=“phone_IMEI”]’)))
phone_IMEI.send_keys(IMEI)

勾选复选框

self.wait.until(EC.presence_of_element_located((By.XPATH, ‘/html/body/main/div[2]/div/p/span’))).click()

点击立即查询

self.wait.until(EC.presence_of_element_located((By.XPATH, ‘//*[@id=“query_IMEI”]’))).click()

定位滑块图片

必须先遍历一遍页面所有元素，否则找不到新弹出的滑块元素

self.web_driver_wait_ruishu(10, “class”, ‘dx_captcha dx_captcha_loading-style-popup dx_captcha_basic dx_captcha-type-basic dx_captcha_basic-style-popup’)
print(“定位到滑块弹窗”)
dx_captcha = self.wait.until(EC.presence_of_all_elements_located((By.XPATH, ‘/html/body/div/div/div[2]/div[2]/div[1]/div[2]/div[2]’)))
print(len(dx_captcha))
if len(dx_captcha) > 1:
dx_captcha = dx_captcha[-1]
else:
dx_captcha = dx_captcha[0]

截图

dx_captcha.screenshot(self.bgImg_path)

剩下的就是识别缺口距离了，并生成移动轨迹

滑块在图片上的位置

x, y = self.template_match(slide_pic, back_pic)

滑块到缺口的距离

dis_x = int((x + 5) * (340 / 552))

return dis_x, dis_y

​
mid = distance * 3 / 4
​

z = random.randint(30, 150)
​
while current < (distance + exceed):

z = z + random.randint(5, 9)
tracks.append([min(current, (distance + exceed)), y, z])
tr = []
for i, x in enumerate(tracks):
tr.append({
‘x’: x[0],
‘y’: _y,

return tr
