selenium实现点击或回车搜索页面：以JD为例

记录一个实现搜索功能的爬虫

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.common.keys import Keys
# 创建WebDriver
driver = webdriver.Firefox()  # 打开网页  
driver.get("https://www.jd.com/?cu=true")  # 替换为你要搜索的网站地址  # 定位搜索框并输入关键词  
search_box_xpath = '//*[@id="key"]'  # 替换为实际的搜索框XPath  
search_box = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, search_box_xpath)))  
search_box.send_keys("替换为要搜索的关键词")  # 替换为要搜索的关键词  # 触发搜索
# 方法一：按下回车键触发搜索  
search_box.send_keys(Keys.RETURN)# 方法二：点击搜索按钮触发搜索（如果有搜索按钮的话）  
# search_button_xpath = "/html/body/div[1]/div[4]/div/div[2]/div/div[2]/button"  # 替换为实际的搜索按钮XPath  
# search_button = driver.find_element(By.XPATH, search_button_xpath)  
# search_button.click()  # 关闭浏览器（在完成所有操作后）  
# driver.quit()
