6.4.1 Message Transmission
SAC
The initiator should ensure that the message is sent once and only once before receiving the message confirmation. In businesses that require high data accuracy, if you need to ensure the unique validity of the sending behavior, you can use the token mechanism (Token). If you need to ensure the unique authenticity of the data contained in the sent message, you can use idempotence. sexual mechanism. 6.4.2 Message confirmation
The logistics information interface system should have a synchronous or asynchronous reception of the message recipient's receipt information and communication abnormality compensation mechanism. Receipt information should include clear message status.
The cancellation status is divided into two types:
Accepted (Accepted), indicating that the recipient has recognized and accepted the information; Rejected (Rejected), indicating that the recipient does not recognize the information. 6.4.3 Message resend mechanism
The logistics information system should have a message resend mechanism. If the sender does not receive a confirmed message, it should perform a retry operation until a confirmed message is received, or it should judge If the number of retries has been exceeded and a delivery failure message is notified. 6.4.4 Message backup mechanism
When an error occurs, the system should automatically back up the file and the cause of the error, and place the file in a specific directory. 6.4.5 Error code publication
Clear error codes and status codes should be published, and the codes should not be ambiguous or confusing. The code should include but not be limited to system code and business code, and a clear distinction should be made. 6.5 Electronic data exchange

When transmitting interface messages, it should include but not Limited to the clear multi-layer structure of message header and message body. Message header
8.2
The message header is used to express the general information of the message, including but not limited to the following information: Message number: the message number used to determine the unique request identity, UUID can be used ;Business code: the business number code determined by the sender and receiver; Sender code: sender identification number; Receiver code: receiver identification number; Send time: the time when the interface message is sent, and its time format should comply with GB/ T7408 regulations. 8.3 The message body
should completely describe the specific business situation.

The system should use SSL technology to ensure the privacy of data transmission. It is recommended to use TLS1.2 and above. The sender can digest the transmitted information, use the private key to digitally sign and encrypt the digest, and send the signature and encryption results to the receiver together with the message.
9.2 Anti-computation tampering
The system should use PKI digital certificate cross-certification to digitally sign messages. It should ensure that data is not tampered with during transmission and achieve non-repudiation of message sending and receiving.
The receiver can use the public key for verification to ensure the integrity of the data. 9.3
Safety specifications
