如何为Swiggy搜索输入框获取正确的Selenium定位器？

我尝试自动化Swiggy平台的食物搜索功能，但在操作搜索输入框时出现错误，用SelectorsHub找定位器也没解决，终端报错如下：

代码片段 #

from selenium import webdriver
import time

from selenium.webdriver import Keys
from selenium.webdriver.common.by import By

browser = webdriver.Chrome()
browser.get('https://google.com')
browser.maximize_window()

search = browser.find_element(By.XPATH, "//textarea[@id='APjFqb']")
search.send_keys("Swiggy")
search.send_keys(Keys.RETURN)

site = browser.find_element(By.PARTIAL_LINK_TEXT, "Swiggy")
site.click()

search_btn = browser.find_element(By.XPATH, "//span[normalize-space()='Search']")
search_btn.click()

search_food = (browser.find_element(By.CSS_SELECTOR, 'button[class*="SearchButton"]'))
search_food.click()

time.sleep(10)

错误信息 #

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//input[@placeholder='Search for restaurants and food']"}

• 补全等待机制：固定time.sleep()不稳定，改用Selenium显式等待，确保元素加载完成后再操作。
• 处理窗口切换：点击Swiggy链接会打开新标签页，必须切换到新窗口才能定位元素。
• 优化定位逻辑：原代码中点击SearchButton属于多余操作，点击搜索图标后直接定位输入框即可。

修改后的代码：

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
from selenium.webdriver import Keys

browser = webdriver.Chrome()
browser.get('https://google.com')
browser.maximize_window()

# 搜索Swiggy
search = WebDriverWait(browser, 10).until(
    EC.presence_of_element_located((By.XPATH, "//textarea[@id='APjFqb']"))
)
search.send_keys("Swiggy")
search.send_keys(Keys.RETURN)

# 点击Swiggy链接并切换到新窗口
site = WebDriverWait(browser, 10).until(
    EC.element_to_be_clickable((By.PARTIAL_LINK_TEXT, "Swiggy"))
)
site.click()
window_handles = browser.window_handles
browser.switch_to.window(window_handles[-1])

# 点击搜索按钮
search_btn = WebDriverWait(browser, 10).until(
    EC.element_to_be_clickable((By.XPATH, "//span[normalize-space()='Search']"))
)
search_btn.click()

# 定位搜索输入框并输入内容
search_input = WebDriverWait(browser, 10).until(
    EC.presence_of_element_located((By.XPATH, "//input[@placeholder='Search for restaurants and food']"))
)
search_input.send_keys("Pizza")
search_input.send_keys(Keys.RETURN)

# 可选择关闭浏览器
# browser.quit()
