使用pyppteer+ddddocr通过极验滑块验证码（附源码）

前言：

        验证码是大多数爬虫都需要克服的难题。pyppteer是目前市场主流的自动化工具之一，它的优势在于不易被浏览器检测到，DDDdocr也是目前主流的验证码识别的第三方模块。接下来就通过python自动化工具和ddddocr等第三方模块完成极验滑块。

一：使用自动化工具打开网站

        目标网站：行为验证4.0-适应型验证码-滑动验证,点选验证,图片验证-极验GeeTest

    # 浏览器 启动参数    start_parm = {        # 关闭无头浏览器        "headless": False,        "args": [            '--disable-infobars',  # 关闭自动化提示框            '--no-sandbox',  # 关闭沙盒模式            '--start-maximized',  # 窗口最大化模式        ],    }    browser = await launch(**start_parm)    page = await browser.newPage()    # 设置网页 视图大小    await page.setViewport(viewport={'width': 1920, 'height': 1080})    await page.Goto('https://www.geetest.com/adaptive-captcha-demo')

二：控制鼠标定位到指定元素

   await page.waitForXPath('//div[@class="type-config"]')  # 等待元素加载    botton1 = await page.xpath('//div[@class="tab-item tab-item-1"]')  # 滑块拼图验证按钮    await botton1[0].click()    await page.click('#captcha', options={        'button': 'left',        'clickCount': 2,        'delay': 300,  # 延迟点击(ms)    })    botton2 = await page.xpath('//*[@aria-label="点击按钮开始验证"]')  # 开始验证按钮    await botton2[0].click()

三：提取滑块拼图照片url

elements_1 = await page.xpath(            '//*[@id="captcha"]/div[2]/div[1]/div[4]/div[1]/div[2]/div/div/div[1]/div[1]/div[1]/@style')  # 滑块图片链接        elements_2 = await page.xpath(            '//*[@id="captcha"]/div[2]/div[1]/div[4]/div[1]/div[2]/div/div/div[1]/div[2]/@style')  # 背景图片链接        for element in elements_1:            sc = await page.evaluate('(element) => element.textContent', element)            sc_url = sc.split('"')[1].split('"')[0]  # 提取滑块图片链接            with open('slice.png', 'wb')as f1:                f1.write(requests.get(sc_url).content)        for element in elements_2:            bg = await page.evaluate('(element) => element.textContent', element)            bg_url = bg.split('"')[1].split('"')[0]  # 提取背景图片链接            with open('bg.png', 'wb') as f2:                f2.write(requests.get(bg_url).content)

四：获取拼图坐标偏移量

async def get_xy():    det = ddddocr.DdddOcr(det=False, ocr=False)    with open('slice.png', 'rb') as f:        target_bytes = f.read()    with open('bg.png', 'rb') as f:        background_bytes = f.read()    try:        res = det.slide_match(target_bytes, background_bytes)        print(res)        return res.get('target')[0]    except:        return False

五：操作鼠标移动滑块

        其中x，y需要根据自己电脑进行微调。

        if target:            # print(target)            botton3 = await page.xpath(                '//*[@id="captcha"]/div[2]/div[1]/div[4]/div[1]/div[2]/div/div/div[2]/div/div[3]')            await botton3[0].hover()  # 鼠标悬停元素上            await page.mouse.down()  # 鼠标落下            await page.waitFor(500)            x = 1116 + target            y = 641            await page.mouse.move(x, y, {'steps': 2})  # 鼠标移动            await page.waitFor(500)            await page.mouse.up()  # 鼠标松开            time.sleep(2)            elements_3 = await page.xpath('//*[@id="captcha"]/div[2]/div[1]/div[3]/div[2]/div/div[2]/text()')            msg = ''            for element in elements_3:                msg = await page.evaluate('(element) => element.textContent', element)            if msg == '验证通过':                break            else:                print(msg)        else:  # 获取坐标失败时刷新验证            botton4 = await page.xpath('//*[@aria-label="刷新验证"]')            await botton4[0].click()

验证通过，欧耶~
