在 Playwright Python 中,你可以使用 `TimeoutError` 类来处理超时异常。如果你想将默认的超时时间从 30000 毫秒改为 10000 毫秒,可以在导入 `TimeoutError` 类时,使用 `as` 关键字给它起一个别名,然后在使用时传入超时时间,代码如下:
```python
from playwright.sync_api import Playwright, sync_playwright, TimeoutError as PlaywrightTimeoutError
with sync_playwright() as playwright:
browser = playwright.chromium.launch()
page = browser.new_page()
try:
# 设置超时时间为 10000 毫秒
page.wait_for_selector('button', timeout=10000)
except PlaywrightTimeoutError:
print('超时异常')
browser.close()
```
在上面的代码中,我们使用 `TimeoutError as PlaywrightTimeoutError` 将 `TimeoutError` 类起了一个别名 `PlaywrightTimeoutError`。然后在使用 `wait_for_selector()` 方法时,传入超时时间参数 `timeout=10000`,表示等待 `button` 元素出现的最长时间为 10000 毫秒。
如果在 10000 毫秒内 `button` 元素未出现,`wait_for_selector()` 方法将会抛出超时异常 `PlaywrightTimeoutError`,我们可以在 `try-except` 语句中捕获这个异常并进行处理。
