Dealing with reCAPTCHA in Python Selenium

问题

I need to automate a web page using python selenium, but it encounters a reCaptcha, which is in another frame. I want to solve the captcha, and continue the script by clicking the login button, when the reCaptcha has been solved; However, this gets tricky, since a frame is involved, and the frame needs to switch back to the default content. Can anyone help me in this regard?

from selenium import webdriver
from selenium.webdriver import ActionChains
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
import time
browser = webdriver.Chrome()
browser.delete_all_cookies()    
browser.maximize_window()
browser.get("https://developer.syntecx.org/ptcl_ebills/signin.php")
browser.switch_to.frame(browser.find_element_by_tag_name("iframe"))
browser.find_element_by_xpath("//*[@id='recaptcha-anchor']/div[1]").click()
time.sleep(20)
browser.switch_to_default_content()
browser.find_element_by_xpath("//*[@id='login']/button").click()

Once you fill in the Email and Password field to click on the recaptcha you can use the following Locator Strategies:

• Code Block:

  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_experimental_option("excludeSwitches", ["enable-automation"])
  options.add_experimental_option('useAutomationExtension', False)
  driver = webdriver.Chrome(options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get("https://developer.syntecx.org/ptcl_ebills/signin.php")
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input#email"))).send_keys("Asad_Ullah@stackoverflow.com")
  driver.find_element_by_css_selector("input#password").send_keys("Asad_Ullah")
  WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe[src^='https://www.google.com/recaptcha/api2/anchor?']")))
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "span.recaptcha-checkbox.goog-inline-block.recaptcha-checkbox-unchecked.rc-anchor-checkbox"))).click()
  driver.switch_to_default_content()
  WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.btn.btn-primary.block.full-width.m-b"))).click()

Don't switch to the iframe.

Everything you need is in #g-recaptcha-response and [data-sitekey] which are both in main context.
