如何捕获所有控制台错误日志剧作家

Question

我尝试了所有这些，

page.on("console", lambda msg: print(f"error: {msg.text}") if msg.type == "error" else None)
page.on("console", lambda msg: print(msg.text))
page.on("pageerror", lambda exc: print(f"uncaught exception: {exc}"))

没有任何效果

终端输出

python main.py 
/home/xxx/.local/lib/python3.9/site-packages/trio/_core/_multierror.py:511: RuntimeWarning: You seem to already have a custom sys.excepthook handler installed. I'll skip installing Trio's custom handler, but this means MultiErrors will not show full tracebacks.
  warnings.warn(

在没有最低限度可重现的示例的情况下，使用示例场景代码来说明用法：

# Listen for all console logs
page.on("console", lambda msg: print(msg.text))

# Listen for all console events and handle errors
page.on("console", lambda msg: print(f"error: {msg.text}") if msg.type == "error" else None)




# Get the next console log
async with page.expect_console_message() as msg_info:
    # Issue console.log inside the page
    await page.evaluate("console.log('hello', 42, { foo: 'bar' })")
msg = await msg_info.value

# Deconstruct print arguments
await msg.args[0].json_value() # hello
await msg.args[1].json_value() # 42
