我正在尝试使用 python playwright 编写脚本以登录网站，这是我的代码：

import json
import sys
import bs4
import urllib.parse

link = 'https://secure.libertycable.com/login.php'
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
    #browser = p.chromium.launch()
    context = browser.new_context(user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.114 Safari/537.36')
    page = context.new_page()
    page.goto(link)
    try:
        try:
            page.click('#close')
        except Exception as e:
            page.wait_for_timeout(1000)
        page.type('#user input[name="email"]', "xxxxx")
        page.type('#myInput input[name="password"]', "xxxxxxxxxxxx")
        page.close()
        context.close()
        browser.close()      
    except Exception as e:
        print("Error in playwright script.")
        page.close()
        context.close()
        browser.close()

这是页面源代码的一部分：

     <form class="form-group" id="login_form2" name="login_form2" method="post" action="do_login.php">\n                <input type="hidden" name="go_url" value="">\n                <div style="width:50%;">\n                <label>Email Address*:</label><br>\n                <input class="form-control" type="email" name="email" id="user" size="25" value="">\n                <label>Password*:</label><br><input class="form-control" type="password" name="password" id="myInput" size="25" value="">\n                    <span toggle="#password-field" class="fa fa-fw fa-eye field-icon toggle-password" title="View Password" onclick="passwordToggle()"></span>\n                </div>\n                <br clear="all">\n                <div class="btn btn-green" onclick="document.getElementById(\'login_form2\').submit();"><i class="fa fa-sign-in fa-fw"></i> Login</div>\n                <br><span class="text-muted">*Please Note: Email address and password are case sensitive!</span>\n                </form>\n                <br>\n                <p><a href="reset-password.php" class="blueText">Forgot Password?</a></p>\n

脚本转到页面，关闭具有 id #close 的弹出窗口，并且工作正常，但是当需要填写输入字段时，脚本什么也不做，有什么帮助吗？

user并且myInput是输入元素本身而不是父元素之一上的 ID。这意味着，使用这样的选择器适用于您的场景：

    page.type('input[name="email"]#user', "xxxxx")
    page.type('input[name="password"]#myInput', "xxxxxxxxxxxx")

它挂起的原因是它找不到元素。我建议按照Playwright 调试工具部分使用DEBUG=pw:api或PWDEBUG=1获取调试日志为什么它挂起 - 在你的情况下，它会告诉你找不到选择器。
