Python 使用selenium解决captcha

我下面的代码是继续解决不同的验证码！请纠正我的错误，因为我不知道是什么原因造成的

from selenium import webdriver
from python3_anticaptcha import ImageToTextTask, CallbackClient
import time
import requests

browser = webdriver.Firefox()

url = 'https://urlmased.com/'
browser.get(url)
time.sleep(10)
username = browser.find_element_by_id("masked")
username.send_keys("testuser")
password = browser.find_element_by_id("masked")
password.send_keys("testpass")

image_link = browser.find_element_by_xpath(
    '//*[@id="masked"]').get_attribute('src')
pic = requests.get(image_link)
if pic.status_code == 200:
    with open("image.png", 'wb') as f:
        f.write(pic.content)
ANTICAPTCHA_KEY = 'masked'
captcha_file = "image.png"
result = ImageToTextTask.ImageToTextTask(
    anticaptcha_key=ANTICAPTCHA_KEY).captcha_handler(captcha_file=captcha_file)

captcha = browser.find_element_by_id("masked")
captcha.send_keys(result['solution']['text'])
login = browser.find_element_by_id("yw2")

请被告知API处于活动状态，以便在找到解决方案之前可以使用它。然后我会改变它

此外，求解精度为100%

正如@pguradiario提到的请求。会话没有做任何事情

from selenium import webdriver
from python3_anticaptcha import ImageToTextTask
import time

browser = webdriver.Chrome()

url = 'https://masked/'
browser.get(url)
time.sleep(10)
username = browser.find_element_by_id("masked")
username.send_keys("testuser")
password = browser.find_element_by_id("masked")
password.send_keys("testpass")

image_link = url + browser.find_element_by_xpath('//*[@id="masked"]').get_attribute('src')
print(image_link)

ANTICAPTCHA_KEY = "masked"
user_answer = ImageToTextTask.ImageToTextTask(anticaptcha_key=ANTICAPTCHA_KEY).\
    captcha_handler(captcha_link=image_link)

captcha = browser.find_element_by_id("masked")
captcha.send_keys(user_answer['solution']['text'])
login = browser.find_element_by_id("masked")

这里的问题是页面源中的验证码URL不是 实际图像URL。这是一个动态生成验证码的脚本 当您使用captcha解算器API解算 与浏览器加载的图像不同。要解决这个问题，我们必须 保存浏览器加载的相同图像。我跟踪了图像请求 然后发现，它使用的是当 浏览器加载了该页面

使用硒：

from selenium import webdriver
from python3_anticaptcha import ImageToTextTask, CallbackClient
from time import sleep
import requests



def GetImageCookies():
    print('Extracting Browser Cookies')
    image_cookies = ''
    for cookie in browser.get_cookies():
        if cookie['name'] == 'ssc':
            image_cookies += 'ssc={};'.format(cookie['value'])
        elif cookie['name'] == 'ghsdfkjlksssalk35bbr':
            image_cookies += 'ghsdfkjlksssalk35bbr={};'.format(cookie['value'])
    # print(image_cookies)
    return image_cookies

def SaveImage(captcha_file = "master.jpg"):
    print('Saving the captcha image')
    header = {
    'Accept': 'image/webp,image/apng,image/*,*/*;q=0.8',
    'Accept-Encoding': 'gzip, deflate, br',
    'Accept-Language': 'en,en-US;q=0.9,ar;q=0.8',
    'Cookie': GetImageCookies(),
    'Host': 'masked',
    'Referer': 'masked',
    'Sec-Fetch-Mode': 'no-cors',
    'Sec-Fetch-Site': 'same-origin',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0'}


    pic = requests.get('https://masked/site/captcha/v/',verify=False,headers = header)
    if pic.status_code == 200:
        with open(captcha_file, 'wb') as f:
            f.write(pic.content)

def SolveCapcha(captcha_file = "master.jpg"):
    print('Solving the captcha image')
    ANTICAPTCHA_KEY = 'masked'  
    result = ImageToTextTask.ImageToTextTask(
        anticaptcha_key=ANTICAPTCHA_KEY).captcha_handler(captcha_file=captcha_file)
    captcha_text = result['solution']['text']
    print('Captcha text is :',captcha_text)
    return captcha_text


browser = webdriver.Firefox()
url = 'https://masked/'
browser.get(url)
def Login():
    SaveImage()
    sleep(5)
    username = browser.find_element_by_id("masked_username")
    username.clear()
    username.send_keys("testuser")
    password = browser.find_element_by_id("masked")
    password.clear()
    password.send_keys("testpass")
    captcha = browser.find_element_by_id("masked")
    captcha.clear()
    captcha_text = SolveCapcha()
    captcha.send_keys(captcha_text)
    login = browser.find_element_by_id("masked").click()
    sleep(5)
    err_message = browser.find_elements_by_id('masked')
    if err_message :
        if err_message[0].text == 'The verification code is incorrect.':
            print(err_message[0].text)
            return False
    return True


"""The logic here is that the image gets downloaded using the cookies but sometimes
the letters are hard to be solved so each time we download the same image with the
same cookies the content of the image will be the same but how it's written is different
So we keep trying till we get it right """
while Login() == False:
    Login()

使用请求和靓汤： 以下是一个不确定它是否有效的想法，您必须测试自己：

from bs4 import BeautifulSoup
def SaveImage(captcha_file = "master.jpg"):
    print('Saving the captcha image')
    header = {
    'Accept': 'image/webp,image/apng,image/*,*/*;q=0.8',
    'Accept-Encoding': 'gzip, deflate, br',
    'Accept-Language': 'en,en-US;q=0.9,ar;q=0.8',
    'Host': 'masked',
    'Referer': 'https://masked/',
    'Sec-Fetch-Mode': 'no-cors',
    'Sec-Fetch-Site': 'same-origin',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0'}


    pic = session.get('https://masked/site/captcha/v/',verify=False,headers = header)
    if pic.status_code == 200:
        with open(captcha_file, 'wb') as f:
            f.write(pic.content)

with requests.Session() as session:
    source      = session.get(url = 'https://masked/',verify=False) # To get the itial cookies  
    soup        = BeautifulSoup(source.text, 'html.parser')  
    token       = soup.find('input', {'name': 'masked'}).get('value')
    SaveImage()
    captcha_text = SolveCapcha()
    post_data={"masked": token,
                'masked[username]': 'testuser',
                'masked[password]': 'testpass',
                'masked[captcha]': captcha_text,
                'masked':''}
    session.post('https://masked/', data=post_data,verify=False)

验证码截图而不是从链接中获取图像应该可以解决这个问题

from selenium import webdriver
from python3_anticaptcha import ImageToTextTask
import time

browser = webdriver.Firefox()

url = 'https://urlmased.com/'
browser.get(url)
time.sleep(10)
username = browser.find_element_by_id("masked")
username.send_keys("testuser")
password = browser.find_element_by_id("masked")
password.send_keys("testpass")

captcha = browser.find_element_by_xpath(
    '//*[@id="masked"]')
captcha_image = captcha.screenshot_as_png
with open('image.png', 'wb') as f:
    f.write(captcha_image)
ANTICAPTCHA_KEY = 'masked'
captcha_file = "image.png"
result = ImageToTextTask.ImageToTextTask(
    anticaptcha_key=ANTICAPTCHA_KEY).captcha_handler(captcha_file=captcha_file)

captcha = browser.find_element_by_id("masked")
captcha.send_keys(result['solution']['text'])
login = browser.find_element_by_id("yw2")

“src”给出了绝对URL，它需要与基本URL连接。我将在页面上获取验证码并将其发送给验证码处理程序。评论不用于进一步讨论；这段对话已经结束。
