请教：ctx.socket.emit的第一个参数只能是字符串，为啥代码能用数组？ #470

const targetSockets = await Socket.find({ user: toUser?._id }); const targetSocketIdList = targetSockets?.map((socket) => socket.id) || []; if (targetSocketIdList.length) { ctx.socket.emit(targetSocketIdList, 'message', messageData); }

请教这里为啥能用数组？ ctx.socket.emit(targetSocketIdList, 'message', messageData);
