这里的问题是页面源中的验证码 URL 不是实际的图像 URL。这是一个动态生成验证码图像的脚本，当您使用验证码求解器 API 时，您正在求解与加载的浏览器不同的图像。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，发现它使用的是浏览器加载页面时生成的唯一 cookie。
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 = {

使用请求和美丽的汤：以下是不确定它是否有效的想法，你必须测试自己：

SaveImage()
