這篇文章主要為大家詳細(xì)介紹了python playwright實(shí)現(xiàn)獲取當(dāng)前頁(yè)面的截圖的相關(guān)方法,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以了解一下

你可以使用 Playwright 來(lái)獲取當(dāng)前頁(yè)面的截圖。以下是一個(gè)示例代碼：

import os
import sys
from playwright.sync_api import sync_playwright


def find_chrome_executable():
    """
    自動(dòng)檢測(cè) Chrome / Chromium 在 Windows / macOS / Linux 平臺(tái)的常見(jiàn)安裝位置。
    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:
        # 不允許 fallback 用內(nèi)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"第一個(gè)鏈接URL：{url}")

                page.goto(url)
                page.wait_for_load_state('load')

                screenshot_path = 'screenshot_after_click.png'
                page.screenshot(path=screenshot_path)

                print(f"截圖已保存到 {screenshot_path}")
            else:
                print("熱搜區(qū)未找到鏈接")
        else:
            print("頁(yè)面上未找到熱搜元素")

        browser.close()


if __name__ == '__main__':
    click_first_link_in_hotsearch_and_get_url()

在這個(gè)示例中，page.screenshot() 方法用于獲取當(dāng)前頁(yè)面的截圖，并將其保存到指定的文件路徑（screenshot.png）。確保替換 ‘https://www.baidu.com’ 為你想要截圖的實(shí)際網(wǎng)址。如果你希望在截圖后不關(guān)閉瀏覽器，記得注釋掉 browser.close() 部分。

注意：截圖之前最好等待頁(yè)面加載完成，以確保獲取到完整的頁(yè)面截圖。在這個(gè)示例中，使用了 page.wait_for_load_state(‘load’) 來(lái)等待頁(yè)面加載完成，但你可能需要根據(jù)實(shí)際情況調(diào)整等待的條件。

知識(shí)擴(kuò)展

下面我們來(lái)看看如何利用Playwright庫(kù)在Python中進(jìn)行屏幕截圖、截取全頁(yè)面長(zhǎng)圖以及特定元素的截圖。

捕獲屏幕截圖保存

page.screenshot(path="screenshot.png")

代碼如下（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")

截長(zhǎng)圖

page.screenshot(path="screenshot.png", full_page=True)

代碼如下（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)

截取單個(gè)元素

先定位到需要截圖的元素，再截圖保存

from playwright.async_api import Playwright
from playwright.sync_api import sync_playwright

def run(playwright: Playwright):
    # 啟動(dòng) chromium 瀏覽器
    browser = p.chromium.launch(headless=False,slow_mo=1000)
    context = browser.new_context()
    # 打開(kāi)一個(gè)標(biāo)簽頁(yè)
    page = context.new_page()
    # 打開(kāi)百度
    page.goto("http://192.168.64.209:8008/#/login")
    # 打印當(dāng)前頁(yè)面title
    print(page.title())
    page.locator(".s-canvas").screenshot(path="example.png")
