在Python中以交互模式运行剧作家
在Python中以交互模式运行剧作家
提问于 2022-08-07 13:22:05
我用剧作家用Python抓取页面。我知道如何使用脚本来做同样的事情，但我是以交互的方式尝试的。
from playwright.sync_api import Playwright, sync_playwright, expect
import time
def run(playwright: Playwright) -> None:
browser = playwright.chromium.launch(headless=False)
context = browser.new_context()
page = context.new_page()
page.goto("https://www.wikipedia.org/")
context.close()
browser.close()
with sync_playwright() as playwright:
run(playwright)我试图在交互模式下这样做，因为：
>>> from playwright.sync_api import Playwright, sync_playwright, expect
>>> playwright = sync_playwright()
>>> browser = playwright.chromium.launch(headless=False)但这给了我一个错误：
Traceback (most recent call last):
File "C:\Users\hpoddar\AppData\Local\Programs\Python\Python310\lib\idlelib\run.py", line 578, in runcode
exec(code, self.locals)
File "<pyshell#2>", line 1, in <module>

使用.start()方法：
>>> from playwright.sync_api import Playwright, sync_playwright, expect
>>> playwright = sync_playwright().start()
>>> browser = playwright.chromium.launch(headless=False)
>>> page = browser.new_page()或者，如果您只想要一个交互式浏览器，而不关心交互式shell，您也可以使用wait_for_timeout函数(只适用于Page对象)，并将超时设置为高值：
from playwright.sync_api import sync_playwright
with sync_playwright() as playwright:
browser = playwright.chromium.launch(headless=False)
page = browser.new_page()
page.wait_for_timeout(10000)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
