220) adding header information of message content, including message type, encryption type, total block number and current block number;
221) encapsulating the message content into a message object;
222) the intranet data transmission module sends the query result message to the extranet data transmission module, and returns to step 202).
3. The cross-network high-frequency data secure transmission method according to claim 2, characterized in that: when decoupling is carried out on transmission contents, a jdk self-contained serialization mode is selected, so that the specific type of the target object does not need to be known during serialization and deserialization, and the judgment of the object type is delayed to a specific use period for judgment.
4. The cross-network high-frequency data secure transmission method according to claim 3, characterized in that: when the query request object is small and the blocking requirement does not exist, blocking is not carried out, and the query request object is small, namely the queried result is smaller than the result of single transmission.
