我要评论你可以使用 playwright 来获取当前页面的截图。以下是一个示例代码：
import os
import sys
from playwright.sync_api import sync_playwright
def find_chrome_executable():
"""
自动检测 chrome / chromium 在 windows / macos / linux 平台的常见安装位置。
找不到返回 none。
"""
if sys.platform.startswith("win"):
paths = [
os.path.expandvars(r"%programfiles(x86)%\google\chrome\application\chrome.exe"),
os.path.expandvars(r"%programfiles%\google\chrome\application\chrome.exe"),
os.path.expandvars(r"%localappdata%\google\chrome\application\chrome.exe"),
]
elif sys.platform.startswith("darwin"): # macos
paths = [
"/applications/google chrome.app/contents/macos/google chrome",
"/applications/chromium.app/contents/macos/chromium",
]
elif sys.platform.startswith("linux"):
paths = [
"/usr/bin/google-chrome",
"/usr/bin/google-chrome-stable",
"/usr/bin/chromium",
"/usr/bin/chromium-browser",
"/snap/bin/chromium",
]
else:
return none
for path in paths:
if os.path.exists(path):
return path
return none
def click_first_link_in_hotsearch_and_get_url():
chrome_path = find_chrome_executable()
if not chrome_path:
print("❌ 未找到本地 chrome，程序退出。")
return
print(f"✔ 使用本地 chrome：{chrome_path}")
with sync_playwright() as p:
# 不允许 fallback 用内置 chromium
browser = p.chromium.launch(executable_path=chrome_path, headless=true)
page = browser.new_page()
page.goto('https://www.baidu.com')
page.wait_for_load_state('load')
hotsearch_selector = '#s-hotsearch-wrapper'
page.wait_for_selector(hotsearch_selector)
hotsearch_element = page.query_selector(hotsearch_selector)
if hotsearch_element:
first_link = hotsearch_element.query_selector("a")
if first_link:
url = first_link.get_attribute('href')
print(f"第一个链接url：{url}")
page.goto(url)
page.wait_for_load_state('load')
screenshot_path = 'screenshot_after_click.png'
page.screenshot(path=screenshot_path)
print(f"截图已保存到 {screenshot_path}")
else:
print("热搜区未找到链接")
else:
print("页面上未找到热搜元素")
browser.close()
if __name__ == '__main__':
click_first_link_in_hotsearch_and_get_url()
在这个示例中，page.screenshot() 方法用于获取当前页面的截图，并将其保存到指定的文件路径（screenshot.png）。确保替换 ‘https://www.baidu.com’ 为你想要截图的实际网址。如果你希望在截图后不关闭浏览器，记得注释掉 browser.close() 部分。
注意：截图之前最好等待页面加载完成，以确保获取到完整的页面截图。在这个示例中，使用了 page.wait_for_load_state(‘load’) 来等待页面加载完成，但你可能需要根据实际情况调整等待的条件。
知识扩展
下面我们来看看如何利用playwright库在python中进行屏幕截图、截取全页面长图以及特定元素的截图。
捕获屏幕截图保存
page.screenshot(path="screenshot.png")
代码如下（示例）：
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch(headless=false, slow_mo=1000)
context = browser.new_context()
page = context.new_page()
page.goto("https://blog.csdn.net/weixin_44688529?spm=1010.2135.3001.5343")
print(page.title())
page.screenshot(path="screenshot.png")
截长图
page.screenshot(path="screenshot.png", full_page=true)
代码如下（示例）：
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch(headless=false, slow_mo=1000)
context = browser.new_context()
page = context.new_page()
page.goto("https://blog.csdn.net/weixin_44688529?spm=1010.2135.3001.5343")
print(page.title())
page.screenshot(path="screenshot.png", full_page=true)
截取单个元素
先定位到需要截图的元素，再截图保存
from playwright.async_api import playwright
from playwright.sync_api import sync_playwright
def run(playwright: playwright):
# 启动 chromium 浏览器
browser = p.chromium.launch(headless=false,slow_mo=1000)
context = browser.new_context()
# 打开一个标签页
page = context.new_page()
# 打开百度
page.goto("http://192.168.64.209:8008/#/login")
# 打印当前页面title
print(page.title())
page.locator(".s-canvas").screenshot(path="example.png")
