图片验证，滑块验证解决

Yuno Wang • • 1年前 • 编程日记 • 阅读(0) • 违法举报

在web端与Android端，登录时会碰到图片验证与滑块验证，解决验证问题，下面上代码

图片验证

识别图片中文字，输入验证

滑块验证解决思路

1、获取滑块滑动的距离

2、模拟拖动滑块，通过验证。

web端滑动操作

from selenium.webdriver import ActionChains

action = ActionChains(driver)

source = driver.find_element_by_xpath("//*[@id='nc_1_n1t']/span")  # 需要滑动的元素
action.click_and_hold(source).perform()  # 鼠标左键按下不放
action.move_by_offset(298, 0)  # 需要滑动的坐标
action.release().perform()  # 释放鼠标

代码操作

import cv2
import requests
from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome()
driver.get("https://www.douban.com/")
driver.maximize_window()

iframe = driver.find_element(By.CSS_SELECTOR, "#anony-reg-new > div > div.login > iframe")
driver.switch_to.frame(iframe)
phone = driver.find_element(By.CSS_SELECTOR,
                            "body > div.account-body.login-wrap.login-start.account-anonymous > div.account-tabcon-start > div.account-form > div:nth-child(3) > div > input")
phone.send_keys('15105408319')
time.sleep(1)
slider_ = driver.find_element(By.CSS_SELECTOR,
                              'body > div.account-body.login-wrap.login-start.account-anonymous > div.account-tabcon-start > div.account-form > div:nth-child(4) > div > div > a')
slider_.click()
time.sleep(3)
iframe = driver.find_element(By.CSS_SELECTOR, "#tcaptcha_iframe")
driver.switch_to.frame(iframe)
while True:
    # 1、获取滑块及滑板地址
    src = driver.find_element(By.CSS_SELECTOR, "#slideBg")
    bug_src_url = src.get_attribute("src")
    src = driver.find_element(By.CSS_SELECTOR, "#slideBlock")
    small_src_url = src.get_attribute("src")
    # 2、下载到本地图片
    with open("../download/big_srs.jpg", "wb") as f:
        f.write(requests.get(bug_src_url).content)
    with open("../download/small_srs.jpg", "wb") as f:
        f.write(requests.get(small_src_url).content)
    # print(bug_src_url)
    # print(small_src_url)
    # 3、图片识别，匹配滑块验证码的距离，滑块和滑板的小图重叠后x轴的距离
    # (0.5932352542877197, 0.8350041508674622, (486, 53), (172, 155))
    big = cv2.imread("../download/big_srs.jpg", 0)  # 以灰度方式加载图片
    small = cv2.imread("../download/small_srs.jpg", 0)  # 以灰度方式加载图片
    res = cv2.matchTemplate(big, small, cv2.TM_CCORR_NORMED)  # 匹配模式        小图在大图中的位置
    value_num = cv2.minMaxLoc(res)  # 匹配小图和大图最左边和最右边的位置
    print(value_num)
    x = value_num[2][0]  # 横坐标
    # 4、缩放比例及校准滑块偏移量。原图680x390，实际页面图283x162
    print(x)
    x = int(x * 283 / 680)  # 缩放比例
    print(x)
    bk = 30 - int(20 * 283 / 680)  # 偏移量
    print(bk)
    x = x - bk
    print(x)
    # 6、通过ActionChains滑动解锁
    action = ActionChains(driver)
    action.click_and_hold(src).perform()  # 鼠标左键按下不放
    # action.drag_and_drop_by_offset(src,x,0).perform()   # 滑块滑动到指定坐标
    action.move_by_offset(x, 0)  # 需要滑动的坐标
    action.release().perform()  # 释放鼠标
    try:
        driver.find_element(By.CSS_SELECTOR, "#tcStatus > div.tc-status--right.table-wrap > div:nth-child(2)")
    except:
        break
time.sleep(5)
driver.quit()

Android端滑动操作

通过scroll_from_element、flick_element 方法来实现下拉操作

TouchAction提供的一些方法：

  • double_tap(on_element) #双击
  • flick_element(on_element, xoffset, yoffset, speed) #从元素开始以指定的速度移动
  • long_press(on_element)　　 #长按不释放
  • move(xcoord, ycoord)　　 #移动到指定的位置
  • perform()　　 #执行链中的所有动作
  • release(xcoord, ycoord)　　 #在某个位置松开操作
  • scroll(xoffset, yoffset) #滚动到某个位置
  • scroll_from_element(on_element, xoffset, yoffset) #从某元素开始滚动到某个位置
  • tap(on_element) #单击
  • tap_and_hold(xcoord, ycoord) #某点按住

因为我们模拟的是移动端的H5自动化测试，首先需要我们将浏览器设置成为手机浏览器（设置之后，模拟会更加真实）

1.以元素为起点向下滑动，实现下拉操作

scroll_from_element(on_element xoffset yoffset)
on_element:开始元素滚动。
xoffset:X偏移量。
yoffset:Y偏移量。

注意：向下滑动为负数，向上滑动为正数

# 将页面滚动条拖到底部，需要设置sleep(1)
sleep(1)
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
# driver.execute_script("window.scrollTo(0, 10000);")
# sleep(3)


import time

from selenium import webdriver

from selenium.webdriver.common.touch_actions import TouchActions

"""设置手机的大小"""

mobileEmulation = {'deviceName': 'Apple iPhone 5'}

options = webdriver.ChromeOptions()

options.add_experimental_option('mobileEmulation', mobileEmulation)

driver = webdriver.Chrome(chrome_options=options)

driver.get('http://m.test.90dichan.com')

driver.maximize_window()

"""定位操作元素"""

button = driver.find_element_by_xpath('//*[@id="pullrefresh"]/div[2]/ul/li[2]/a/div[2]/span')

time.sleep(3)

Action = TouchActions(driver)

"""从button元素像下滑动200元素"""

Action.scroll_from_element(button, 0, -200).perform()

time.sleep(3)

driver.close()

2.以元素为起点用一定速度向下滑动，实现下拉操作

flick_element(on_element, xoffset, yoffset, speed)；
on_element #操作元素定位
xoffset　　 #x轴偏移量
yoffset #y轴偏移量
speed #速度

注意：向上滑动为负数，向下滑动为正数

import time

from selenium import webdriver

from selenium.webdriver.common.touch_actions import TouchActions

"""设置手机的大小"""

mobileEmulation = {'deviceName': 'Apple iPhone 5'}

options = webdriver.ChromeOptions()

options.add_experimental_option('mobileEmulation', mobileEmulation)

driver = webdriver.Chrome(chrome_options=options)

driver.get('http://m.test.90dichan.com')

driver.maximize_window()

"""定位操作元素"""

button = driver.find_element_by_xpath('//*[@id="pullrefresh"]/div[2]/ul/li[2]/a/div[2]/span')

time.sleep(3)

Action = TouchActions(driver)

"""从button元素像下滑动200元素，以50的速度向下滑动"""

Action.flick_element(button, 0, 200, 50).perform()

time.sleep(3)

driver.close()
