python playwright chromium.connect()怎么用

您好！关于您的问题，让我来为您解答一下：

在使用Python Playwright时，可以使用以下代码连接到Chromium：

from playwright.sync_api import Playwright, sync_playwright

def run(playwright: Playwright) -> None:
    with playwright.chromium.connect_over_websocket("ws://localhost:1234/devtools/browser") as browser: 
        page = browser.new_page() 
        page.goto("https://example.com") 

with sync_playwright() as playwright:
    run(playwright)

您需要将 "ws://localhost:1234/devtools/browser" 更改为适当的Chrome DevTools地址，以与Chromium进行通信。

希望这可以帮助您解决问题！如果您有任何其他问题，可以随时问我。

python playwright chromium以websocket方式启动为被连接方

好的，您的问题是关于如何使用Python Playwright以WebSocket方式启动Chromium作为被连接方。您可以使用以下代码：

from playwright.sync_api import Playwright, sync_playwright

def run(playwright: Playwright) -> None:
    browser = playwright.chromium.connect_over_websocket("wss://HOST:PORT/playwright")
    #使用WebSocket连接Chromium实例
    page = browser.new_context().new_page()
    #创建新页面
    page.goto('https://example.com')
    #进行页面导航
 
with sync_playwright() as playwright:
    run(playwright)

将代码中的“HOST”和“PORT”替换为WebSocket服务的主机和端口即可。这将使用Python Playwright连接WebSocket服务器并启动Chromium实例作为被连接方，然后创建一个新的页面并在其中导航到指定的URL。

python playwright连接debug浏览器

为了连接 debug 浏览器，首先需要安装 playwright 和浏览器的 debug 版本。然后使用以下代码进行连接：

from playwright.sync_api import Playwright, async_playwright

async def connect_to_browser() -> Playwright:
    async with async_playwright() as playwright:
        browser = await playwright.chromium.launch(headless=False) # 使用非 headless 模式启动浏览器
        context = await browser.new_context()
        page = await context.new_page()
        # 连接浏览器的 WebSocket 调试端口
        await page.goto("chrome://version")
        version = await page.textContent(".version")
        debugger_url = f"ws://{version.split(' ')[-1]}/devtools/browser/{page.context._connection._sessionId}"
        await context.close()
        return await playwright.chromium.connect_over_websocket(debugger_url=debugger_url, timeout=3000)

browser = connect_to_browser().result()

这段代码会启动一个非 headless 模式的 Chromium 浏览器，并在浏览器中输入 `chrome://version` 进入版本信息页面。然后通过解析页面上的版本号，得到浏览器的 WebSocket 调试端口地址，再通过 playwright 的 `connect_over_websocket` 方法连接到浏览器并返回浏览器对象。
