状态栏消息处理

代码实现：

class SapMessageType(enum.Enum):
    SUCCESS = "S"
    WARNING = "W"
    ERROR = "E"
    ABORT = "A"
    INFORMATION = "I"


class SapStatusMessage:

        self.message_as_popup = message_as_popup
        self.message_type = SapMessageType(message_type)
        self.message_text = message_text
        self.message_id = message_id
        self.message_number = message_number
        self.message_parameters = message_parameters


class SapStatusBar:

    def __new__(cls, *args, **kwargs):
        if not hasattr(cls, 'instance'):
            cls.instance = super().__new__(cls, *args, **kwargs)
        return cls.instance

    @staticmethod
    def get_message(session, status_bar):
        message = None
        if session and status_bar:
            try:
                bar = session.findById(status_bar)
                message_type = bar.MessageType.strip()
                if message_type:
                    message_as_popup = bar.MessageAsPopup
                    message_text = bar.Text.strip()
                    message_id = bar.MessageId.strip()
                    message_number = bar.MessageNumber.strip()
                    parameters = SAP_MESSAGES.get(message_id + message_number, [str(i) for i in range(8)])
                    message_parameters = {name: bar.MessageParameter(i).strip() for i, name in enumerate(parameters)}
                    message = SapStatusMessage(

            except Exception as _:
                pass
        return message
