为什么只有当用户手动按下 chromedriver 实例中的按钮时才会出现这个新的 window 通知？硒相关

Question

我有一个简单的 python 程序，它用 chromedriver.exe 打开 this page，然后点击位于该页面右上角的钱包图标，然后点击MetaMask 钱包按钮，在这里：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service

opt.add_argument('--user-data-dir='+r'C:\Users\ResetStoreX\AppData\Local\Google\Chrome\User Data') #Add the user data path as an argument in selenium Options
opt.add_argument("--profile-directory=Default") #Add the profile directory as an argument in selenium Options
s = Service(r'C:\Users\ResetStoreX\AppData\Local\Programs\Python\Python39\Scripts\chromedriver.exe') #Use the chrome driver located at the corresponding path  

driver = webdriver.Chrome(service=s, options=opt) #execute the chromedriver.exe with the previous conditions
driver.implicitly_wait(10)
driver.get('https://opensea.io/') #go to the opensea main page.

initial_page = driver.current_window_handle  #make the previous page the current one
WebDriverWait(driver, 3).until(EC.element_to_be_clickable((By.XPATH, '//*[@id="__next"]/div/div[1]/nav/ul/div[2]/li/button'))) #wait for the wallet button to be enabled for clicking
wallet_button = driver.find_element(By.XPATH, '//*[@id="__next"]/div/div[1]/nav/ul/div[2]/li/button')
wallet_button.click() #click that wallet button
#time.sleep(1)
wallet_options = driver.find_elements(By.XPATH, "//*[@data-testid='WalletSidebar--body']//li")
for i in wallet_options:
    if "MetaMask" in i.get_attribute('innerText'): #find the MetaMask wallet button
        i.click() #click the MetaMask wallet button

我在测试这个程序时注意到的问题是，在通过自动化点击 MetaMask 钱包按钮后，预期的 Metamask Notification window 从未显示，而当前的 window 一直在加载该按钮永远如下所示：

但是，如果用户在同一个 chrome 实例中手动点击同一个 MetaMask 钱包按钮，Metamask Notification window 会立即按预期出现，要求用户登录然后将钱包连接到该站点，如下所示：

我什至在使用此代码按下 MetaMask 钱包按钮（通过自动化）后检查是否还有另一个隐藏的 window 句柄，但没有别的：

for handle in driver.window_handles:
            if handle != initial_page:
                login_page = handle
                driver.switch_to.window(login_page)

所以，我很困惑，为什么那个按钮显然只在用户按下时起作用，而在程序按下时却不起作用？一如既往，如果有人能解释发生了什么以及我该如何解决这个问题，我将不胜感激？

我已经弄清楚了，这是一件愚蠢的事情，我只需要添加扩展路径（must be compressed 作为 .crx 文件）作为 Selenium 的 [=12] 的参数=]，这里是改进后的代码：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service

opt.add_argument('--user-data-dir='+r'C:\Users\ResetStoreX\AppData\Local\Google\Chrome\User Data') #Add the user data path as an argument in selenium Options
opt.add_argument("--profile-directory=Default") #Add the profile directory as an argument in selenium Options
extension_path = r'C:\Users\ResetStoreX\AppData\Local\Google\Chrome\User Data\Default\Extensions\nkbihfbeogaeaoehlefnkodbefgpgknn.8.1_0.crx' #assign the extension path of the compressed Metamask extension to this variable
opt.add_extension(extension_path) #add the extension_path as argument

s = Service(r'C:\Users\ResetStoreX\AppData\Local\Programs\Python\Python39\Scripts\chromedriver.exe') #Use the chrome driver located at the corresponding path  

driver = webdriver.Chrome(service=s, options=opt) #execute the chromedriver.exe with the previous conditions
driver.implicitly_wait(10)
driver.get('https://opensea.io/') #go to the opensea main page.

initial_page = driver.current_window_handle  #make the previous page the current one
WebDriverWait(driver, 3).until(EC.element_to_be_clickable((By.XPATH, '//*[@id="__next"]/div/div[1]/nav/ul/div[2]/li/button'))) #wait for the wallet button to be enabled for clicking
wallet_button = driver.find_element(By.XPATH, '//*[@id="__next"]/div/div[1]/nav/ul/div[2]/li/button')
wallet_button.click() #click that wallet button
#time.sleep(1)
wallet_options = driver.find_elements(By.XPATH, "//*[@data-testid='WalletSidebar--body']//li")
for i in wallet_options:
    if "MetaMask" in i.get_attribute('innerText'): #find the MetaMask wallet button
        i.click() #click the MetaMask wallet button

因此当您编译增强代码时，它会生成以下输出：

我注意到这个程序最终打开了 一个 chromedriver 选项卡 和 一个新的 window 来访问 Metamask钱包（即 两者用于同一事物）。

如果有人想出如何防止 MetaMask 选项卡如图所示打开，请在评论中告诉我。

Why does this new window notification appear only when the user has manually pressed a button in a chromedriver instance? Selenium related
