使用 Playwright 在 Python 中从学校日历 URL 添加 iCal 事件

问：

我目前正在使用 Playwright 编写一个 Python 脚本，以自动执行将 iCal 链接添加到 Google 日历的过程。该脚本成功浏览了身份验证过程，输入了登录凭据，但在尝试在 Google 日历的“按网址添加”页面上输入网址时遇到了问题。它必须在 headless = True 中

from playwright.sync_api import sync_playwright
import time
from playwright.sync_api import Page

with sync_playwright() as playwright:
    browser = playwright.chromium.launch(headless=True, slow_mo=5000)
    context = browser.new_context()
    page = context.new_page()
    page.goto("https://accounts.google.com/v3/signin/identifier?dsh=S1611624178:1665765818620%20318&continue=https://calendar.google.com/calendar/r&followup=https://calendar.google.com/calendar/r&osid=1&passive=1209600&service=cl&flowName=GlifWebSignIn&flowEntry=ServiceLogin&ifkv=AQDHYWrL2lk0_Bcr1n1Y-f-i1sNZRKJK8CNisliX9rpozkqKhY2Jby8gsVZ_wDz_oHqiWmN6uZ6s6g&ec=wgc-calendar-globalnav-signin")
    userLogin = "username "
    userPass = "password"
    page.fill('input[type="email"]', userLogin)
    page.wait_for_selector('#identifierNext >> button', state="visible")
    page.wait_for_timeout(2000)  

    page.click('#identifierNext >> button')
    page.evaluate('''() => {
        const passwordInput = document.querySelector('input[type="password"]');
        passwordInput.style.display = 'inline';  // or 'block' or 'inline-block'
    }''')
    password_input = page.wait_for_selector('input[type="password"]', state="visible")
    password_input.fill(userPass)
    page.click('button >> nth=1')
    page.goto('https://calendar.google.com/calendar/u/0/r/settings/addbyurl')
    url_to_inject = 'https://brightspace.uri.edu/d2l/le/calendar/feed/user/feed.ics?token=althvrqormrwijfhdbe8'

    page.evaluate('''(url) => {
        const inputField = document.querySelector('input[jsname="YPqjbf"]');
        if (inputField) {
            // Click on the input field
            inputField.click();
            inputField.focus();

            inputField.click();
            // Set the value
            inputField.value = url;
        }
    }''', url_to_inject)
    # Check if the attribute is set on the input field
    attribute_value = page.evaluate('(url) => document.querySelector(\'input[jsname="YPqjbf"]\').getAttribute(\'data-injected\')', url_to_inject)

    if attribute_value == 'true':
        print("Script injection successful!")
    else:
        print("Script injection failed!") 

我得到错误：

playwright._impl._api_types.Error: TypeError: Cannot read properties of null (reading 'style')
    at eval (eval at evaluate (:208:30), <anonymous>:3:23)
    at UtilityScript.evaluate (<anonymous>:215:19)
    at UtilityScript.<anonymous> (<anonymous>:1:44)

该输入字段的 HTML 代码段：

<input type="text" value="" id="c67" jsname="YPqjbf" class="VfPpkd-fmcmS-wGMbrd " jsaction="focus:AHmuwe;blur:O22p3e;input:YPqjbf; mousedown:UX7yZ; mouseup:lbsD7e; pointerdown:QJflP; pointerup:HxTfMe; touchstart:p6p2H; touchend:yfqBxc;" aria-controls="c68" aria-describedby="c68" aria-labelledby="c64" maxlength="1024" autocomplete="off">

我尝试了很多方法，我了解它的动态，我希望它输入它，然后我可以在它执行所有其他操作后获取嵌入式代码：

#Checkbox after url input
 # page.evaluate('''(selector) => {
    # const checkbox = document.querySelector(selector);
    # if (checkbox) {
    #     checkbox.checked = true;
    #     checkbox.dispatchEvent(new Event('change'));
    # }
    # }''', 'input[jsname="YPqjbf"][type="checkbox"]')
#Add button clicked
    # page.evaluate('''(selector) => {
    # const button = document.querySelector(selector);
    # if (button) {
    #     button.click();
    # }
    # }''', 'button[jsname="V67aGc"]')

    # page.get_by_text("All Courses - University of Rhode Island").click()
    # page.get_by_role("treeitem", name="Integrate calendar").click()
    
    
    
    
    #embedded code link
    # dynamic_selector = '[jsname="YPqjbf"]'
    # page.wait_for_selector(dynamic_selector, timeout=20000)
    # embed_code_element = page.locator(dynamic_selector).nth(4)
    # print(embed_code_element)
    # element_html = str(embed_code_element.input_value())
    # page.screenshot(path='screenshot.png')
    # print(element_html)
