Detaches the CDPSession from the target. Once detached, the CDPSession object won't emit any events and can't be used to send messages.

异步

async def detach(self) -> None

CDPSession.detach

Detaches the CDPSession from the target. Once detached, the CDPSession object won't emit any events and can't be used to send messages.

on

同步

def on(self, event: str, f: Callable[..., NoneType]) -> None

支持的重载：

def on(self, event: Literal['close'], f: Callable[[ForwardRef('CDPSession')], ForwardRef('None')]) -> None
def on(self, event: str, f: Callable[..., NoneType]) -> None

Registers the function f to the event name event.

异步

def on(self, event: str, f: Callable[..., Optional[Awaitable[NoneType]]]) -> None

支持的重载：

def on(self, event: Literal['close'], f: Callable[[ForwardRef('CDPSession')], ForwardRef('Union[Awaitable[None], None]')]) -> None
def on(self, event: str, f: Callable[..., Optional[Awaitable[NoneType]]]) -> None

Registers the function f to the event name event.

once

同步

def once(self, event: str, f: Callable[..., NoneType]) -> None

支持的重载：

def once(self, event: Literal['close'], f: Callable[[ForwardRef('CDPSession')], ForwardRef('None')]) -> None
def once(self, event: str, f: Callable[..., NoneType]) -> None

The same as self.on, except that the listener is automatically removed after being called.

异步

def once(self, event: str, f: Callable[..., Optional[Awaitable[NoneType]]]) -> None

支持的重载：

def once(self, event: Literal['close'], f: Callable[[ForwardRef('CDPSession')], ForwardRef('Union[Awaitable[None], None]')]) -> None
def once(self, event: str, f: Callable[..., Optional[Awaitable[NoneType]]]) -> None

The same as self.on, except that the listener is automatically removed after being called.

remove_listener

同步

def remove_listener(self, event: Any, f: Any) -> None

Removes the function f from event.

异步

def remove_listener(self, event: Any, f: Any) -> None

Removes the function f from event.
