我读了很多关于应该安装哪些库来打印URL链接或打开web链接的文章，但我对应该做什么或安装什么感到困惑，因为它们不满足我的需求。我需要一种方法，如果我输入一个要搜索的句子，它会在输出中将URL下的描述打印为字符串：如图所示：我需要的示例
我使用IDLE(python 3.9 64位(。
使用Selenium控制真实web浏览器的示例代码。
首先打开浏览器并加载页面google.com
接下来，它将关闭弹出对话框，要求获取cookie
接下来，它将填充搜索字段并单击ENTER
最后用class="g"获取所有<div>，并搜索所有可能有文本的<span>。
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
query = 'what is the sound of elephant'
url = 'https://google.com/'
driver = webdriver.Firefox()
driver.get(url)
time.sleep(2)
# --- close popup dialog ---
items = driver.find_elements_by_xpath('//button[div[@role]]')
items[1].click()
time.sleep(2)
# --- fill input ---
items = driver.find_elements_by_xpath('//input[@maxlength]')
items[0].send_keys(query + Keys.ENTER)
time.sleep(2)
# --- get results ---
items = driver.find_elements_by_xpath('//div[@class="g"]') # absolute xpath
print('len(items):', len(items))
for item_number, item in enumerate(items):
print('n--- item:', item_number, '---n')
spans = item.find_elements_by_xpath('./div/div/div/div/span') # relative xpath
for number, s in enumerate(spans):
print('- span:', number, '-')
print(s.text.strip())
结果：
因为谷歌可以在网络浏览器(波兰语(中检测到我的语言设置，所以一些结果是波兰语(即日期(
