验证SMPPLIB中发送的SMS，并获取pdu.message_id

Question

如果消息发送成功，我想验证PDU，然后获取pdu.message_id并将其存储在数据库中。

client.set_message_sent_handler(
    lambda pdu: sys.stdout.write('sent {} {}\n'.format(pdu.sequence, pdu.message_id))
)
client.set_message_received_handler(
    lambda pdu: sys.stdout.write('delivered {}\n'.format(pdu.receipted_message_id))
)

client.connect()
client.bind_transceiver(system_id='', password='')

parts, encoding_flag, msg_type_flag = smpplib.gsm.make_parts('Test message ID \n'+ msg_uuid.replace('-', '') +'\nTimestamp ' + str(datetime.now()) + '\n')

for part in parts:
    pdu = client.send_message(
        receipted_message_id=msg_uuid,

        source_addr_ton=smpplib.consts.SMPP_TON_INTL,
        source_addr_npi=smpplib.consts.SMPP_NPI_ISDN,

        source_addr='PyTestSMPP',

        dest_addr_ton=smpplib.consts.SMPP_TON_INTL,
        dest_addr_npi=smpplib.consts.SMPP_NPI_ISDN,

        destination_addr='0030...',
        short_message=part,

        data_coding=encoding_flag,
        esm_class=msg_type_flag,
        registered_delivery=True,
    )

我是Python的新手，不确定如何验证消息是否已发送。 以及如何使pdu.message_id超出此范围：

client.set_message_sent_handler(
        lambda pdu: sys.stdout.write('sent {} {}\n'.format(pdu.sequence, pdu.message_id))
)
