将 AgentCore 浏览器与剧作家一起使用

你可以将 Playwright 自动化框架与浏览器工具一起使用：

步骤 1：安装依赖关系

创建一个项目文件夹（如果你之前没有创建过）并安装所需的软件包：

mkdir agentcore-browser-quickstart
cd agentcore-browser-quickstart
python3 -m venv .venv
source .venv/bin/activate

安装所需的软件包：

pip install bedrock-agentcore playwright boto3 nest-asyncio

这些软件包提供：

第 2 步：使用 Playwright 控制浏览器

无需代理框架或 LLM 即可直接使用浏览器。当你想对浏览器自动化进行编程控制时，这很有用。Amazon Bedrock AgentCore 提供与 Playwright 的集成，实现浏览器自动化

异步剧作家示例

创建一个名为的文件direct_browser_playwright.py并添加以下代码：

from playwright.async_api import async_playwright, Playwright, BrowserType
from bedrock_agentcore.tools.browser_client import browser_session
import asyncio

async def run(playwright: Playwright):
    # Create and maintain a browser session
    with browser_session('us-west-2') as client:
        # Get WebSocket URL and authentication headers
        ws_url, headers = client.generate_ws_headers()

        # Connect to the remote browser
        chromium: BrowserType = playwright.chromium
        browser = await chromium.connect_over_cdp(
            ws_url,
            headers=headers
        )

        # Get the browser context and page
        context = browser.contexts[0]
        page = context.pages[0]

        try:
            # Navigate to a website
            await page.goto("https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/what-is-bedrock-agentcore.html")

            # Print the page title
            title = await page.title()
            print(f"Page title: {title}")

            # Keep the session alive for 2 minutes to allow viewing
            print("\n\nBrowser session is active. Check the AWS Console for live view.")
            await asyncio.sleep(120)

        finally:
            # Clean up resources
            await page.close()
            await browser.close()

async def main():
    async with async_playwright() as playwright:
        await run(playwright)

# Run the async function
if __name__ == "__main__":
    asyncio.run(main())

将 Playwright 示例与实时视图同步

或者，您可以将同步 API 与集成的实时取景服务器配合使用：

from playwright.sync_api import sync_playwright, Playwright, BrowserType
from bedrock_agentcore.tools.browser_client import browser_session
from browser_viewer import BrowserViewerServer
import time

def run(playwright: Playwright):
    # Create the browser session and keep it alive
    with browser_session('us-west-2') as client:
        ws_url, headers = client.generate_ws_headers()

        # Start viewer server
        viewer = BrowserViewerServer(client, port=8005)
        viewer_url = viewer.start(open_browser=True)

        # Connect using headers
        chromium: BrowserType = playwright.chromium
        browser = chromium.connect_over_cdp(
            ws_url,
            headers=headers
        )

        context = browser.contexts[0]
        page = context.pages[0]

        try:
            page.goto("https://amazon.com/")
            print(page.title())
            time.sleep(120)
        finally:
            page.close()
            browser.close()

with sync_playwright() as playwright:
    run(playwright)

运行脚本

执行任一脚本：

python direct_browser_playwright.py

预期产出

您应该看到打印的页面标题（例如，Page title: What is Amazon Bedrock AgentCore? - Amazon Bedrock AgentCore）。该脚本会使浏览器会话保持活动状态 2 分钟，然后再关闭。

两个例子：
