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
当您使用验证码求解器 API 时，您正在解决一个问题
与浏览器加载的图像不同。为了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
并发现，它使用的是在
浏览器加载页面。
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',

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)

SaveImage()

print(err_message[0].text)
return False
return True
"""The logic here is that the image gets downloaded using the cookies but sometimes

while Login() == False:
Login()
使用 Requests 和 Beautiful soup：
以下是不确定是否有效的想法，您必须自己测试：
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)
