最近在寫PChome爬蟲時登入時的驗證碼一直解決不了
有試過搭配2Captcha的解決方案但是當我把2Captcha的回傳驗證碼Token填入帶去PChome的LoginApi 時一樣說我

{"Code":"403-03-011","Msg":"reCAPTCHA Verify Fail"}

reCAPTCHA Verify Fail

我採用的是requests 的方式不是Selenium 想請問是我的使用方式錯了嗎

from twocaptcha import TwoCaptcha
import requests
login_url = 'https://ecvip.pchome.com.tw/login/v3/login.htm'
login_sitekey = '6Le3jvYaAAAAAPhQTZe9zO6uNQg3OfdRZSTNuw7B' #PCHOME的recaptcha 的SiteKey
session = requests.Session()
headers = {

    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/111.0.0.0 Safari/537.36',
    
}
def solve_recaptcha_v3(sitekey, url):
    solver = TwoCaptcha("xxxx")
    try:
        result = solver.recaptcha(
            sitekey=sitekey,
            url=url,
            version='v3',
            invisible=1,
            enterprise=1,
            action='login',
            score=0.9
            )
    except Exception as e:
        return False
    else:

        return result 
        sys.exit('result: ' + str(result))
            
def login_recaptcha_token():
    # get token
    token = solve_recaptcha_v3(login_sitekey, login_url)
    return token['code']

def login(email, password): #登入Func
    token = login_recaptcha_token() #取得recaptcha TOKEN
    if token == False:
        print("Failed Get recaptcha_token")
        return False
    res = session.get(login_url, headers=headers)
    #update cookies
    session.cookies.update(res.cookies)
    print(session.cookies.get_dict())
    
    testURL = f"https://ecvip.pchome.com.tw/ecapi/member/v3.1/recaptcha?op=login&_={str(int(time.time() * 1000))}" #這裡好像會先去判斷Token是否有效
    for i in range(1, 100):
        res = session.post(testURL, headers=headers,json={"Account": email, "reCaptchaToken": token})
        print(res.text)
        json_data = json.loads(res.text)
        if json_data['Status'] == "Done":
            break
        time.sleep(1)
    
    
    res = session.post(f"https://ecvip.pchome.com.tw/ecapi/member/v3.1/login", headers=headers, json= {"Account": email, "Pwd": "xxxx", "IsSave": 0, "reCaptchaToken": token}) #登入API
    #print({"Account": email, "Pwd": "xxxx", "IsSave": 0, "reCaptchaToken": token})
    print(res.text)

if __name__ == '__main__':
        login("xxx@google.com", "xxxx")

以上是我的CODE
但是當我發送登入API都是回傳
{"Code":"403-03-011","Msg":"reCAPTCHA Verify Fail"}

程式碼看起來沒問題，可能是PChome網站的驗證機制變強了，因為reCAPTCHA的驗證就是要擋非真實人類的行為，導致你的reCAPTCHA驗證失敗。

換個思路可能的解決方案是嘗試使用selenium，因為selenium可以模擬人類瀏覽行為，更有可能通過reCAPTCHA的驗證。請參考以下selenium的例子：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

def login(email, password):
    driver = webdriver.Chrome(executable_path='YOUR_CHROME_DRIVER_PATH')
    driver.get("https://ecvip.pchome.com.tw/login/v3/login.htm")

    email_input = driver.find_element_by_id("loginAcc")
    password_input = driver.find_element_by_id("loginPwd")

    email_input.send_keys(email)
    password_input.send_keys(password)

    time.sleep(5)  # 等待reCAPTCHA載入完成

    login_button = driver.find_element_by_id("loginButton")
    login_button.click()

    WebDriverWait(driver, 60).until(
        EC.presence_of_element_located((By.ID, "logged"))
    )

    print("登入成功！")

if __name__ == '__main__':
    login("your_email@example.com", "your_password")
