[0049] In cross-border e-commerce declarations, there is a correspondence between message type and sending entity. For example, electronic orders are sent by e-commerce companies, payment vouchers are sent by payment companies, and logistics waybill information is sent by logistics companies.

[0050] Figure 1 This application illustrates a customs declaration method provided in an embodiment, the method comprising:

[0051] Step 101: In response to the order declaration request from the e-commerce platform, obtain the corresponding declaration configuration information of the target customs based on the order declaration request;

[0052] Step 102: Use the message type template and value mapping template to construct the declaration configuration information into a declaration message;

[0053] Step 103: Encrypt the declaration message and send it to the customs declaration system so that the customs declaration system can decrypt the declaration message and verify the declaration.

[0054] In one possible implementation, step 102 involves invoking a message type template and a value mapping template to construct a declaration message from the declaration configuration information, including:

[0055] A declaration configuration message is generated based on the declaration configuration information and the message type template; the message type template is specified by the target customs. Field preprocessing is performed on the declaration configuration message to obtain the preprocessed declaration configuration message. The preprocessed declaration configuration message is adjusted according to the business logic of the e-commerce platform to obtain the adjusted declaration configuration message. The adjusted declaration configuration message is merged with the value mapping template to generate the declaration message; the value mapping template is specified by the target customs.

[0056] In one possible implementation, the method further includes, before merging the adjusted declaration configuration message with the value mapping template:

[0057] Convert the adjusted declaration configuration message into a declaration configuration message in the format specified by the target customs; use the target customs-specified format parsing library to read the value mapping template and obtain the value mapping template in the format specified by the target customs.

[0058] In one possible implementation, the declaration configuration message undergoes field preprocessing to obtain a preprocessed declaration configuration message, including:

[0059] Adjust the declaration configuration message based on the target customs address length; perform character filtering and / or escaping on the adjusted declaration configuration message to obtain the preprocessed declaration configuration message.

[0060] In one possible implementation, the adjusted declaration configuration message is subjected to character filtering and / or escaping processing to obtain a preprocessed declaration configuration message, including:

[0061] By comparing the target customs's filtered character table, characters present in the filtered character table in the adjusted declaration configuration message are deleted; and / or, based on the escape mapping table, characters present in the escape mapping table in the adjusted declaration configuration message are escaped.

[0062] By preprocessing fields and adjusting business logic, we can improve data accuracy and reduce reporting problems caused by data errors.

[0063] In one possible implementation, the preprocessed declaration configuration message is adjusted according to the business logic of the e-commerce platform to obtain an adjusted declaration configuration message, including:

[0064] The preprocessed declaration configuration message is processed to generate an order identifier, confirm package details, and / or remove duplicate addresses, resulting in an adjusted declaration configuration message.

[0065] In one possible implementation, step 103, encrypting the declaration message and sending it to the customs declaration system, includes:

[0066] The declaration message is encrypted according to the encryption method specified by the target customs to obtain an encrypted message; the encrypted message is digitally signed to obtain a signed message; and the signed message is sent to the customs declaration system of the target customs.

[0067] The use of message type templates and value mapping templates to construct declaration messages allows for flexible adaptation to different customs requirements, ensuring data accuracy and consistency. Encrypted declaration messages protect sensitive information from unauthorized access or tampering during transmission, improving the accuracy and efficiency of customs declarations.

[0068] The methods provided in the embodiments of this application will be explained in detail below with reference to the accompanying drawings.

[0069] In the first stage, the corresponding customs template configuration information is obtained based on the order declaration requests from the e-commerce platform.

[0070] Step 1: Receive the order declaration request sent by the e-commerce platform; the order declaration request carries order information and logistics information, such as order number, product details, quantity, value, shipping location, destination, etc.

[0071] Step 2: Match the customs declaration corresponding to the order based on the order information and logistics information, and obtain the declaration configuration information of the target customs.

[0072] The customs code for the template declaration can be determined through built-in logic or by querying the database. Further, the database can be queried using order information and the customs code to find the corresponding customs declaration template configuration information. The declaration template configuration information includes: declaration form format, required fields, specific requirements, coding rules, etc.

[0073] Phase 2: Construct a thread class compatible with the old configuration based on the customs template configuration information.

[0074] Due to system upgrades or migrations, the physical location of class files in the file system has changed. Because of this change, all code referencing this class needs to be updated to reflect the new file path. This may involve modifying import statements, changing the classpath in configuration files, or specifying the new classpath directly in the code.

[0075] In the third stage, the aforementioned thread class is started, and the message type template and value mapping template are called to construct the declaration configuration information into a declaration message.

[0076] Step 1: Generate the declaration configuration message based on the declaration configuration information and message type template; the message type template is specified by the target customs.

[0077] The aforementioned message type template can be a CEB511 message. The CEB511 message type is an electronic waybill, a message format used in customs electronic data interchange for declaring logistics-related information. The message name will include the message type (e.g., CEB311 or CEB511), the sender's enterprise code (senderId), and a timestamp and serial number. The message structure typically includes a message header and specific business data. The message header may include a unique message ID (MessageID), message type (MessageType), enterprise organization code or unified social credit code (OrgCode), and transmitting enterprise code (CopCode), etc. Specific message formats and content may vary depending on the requirements of different customs authorities and different versions of data interchange standards. Therefore, in practice, it is necessary to refer to the latest customs data interchange specifications and guidelines.

[0078] Step 2: Perform field preprocessing on the declaration configuration message to obtain the preprocessed declaration configuration message.

[0079] Write functions to process fields according to configuration files or preset rules. Field configuration optimization includes data cleaning and validation processes to ensure data conforms to specific formats and business rules, ensuring message security and compatibility. Processing includes dynamically adjusting address field lengths, filtering special characters, and escaping, ensuring address fields comply with specific customs system restrictions.

[0080] Address length control: Defines maximum and minimum length limits, truncates addresses that exceed the length or pads addresses that are insufficient.

[0081] Special character filtering: Determine which characters are allowed and which are not, and remove or replace the disallowed characters.

[0082] Escape handling: For certain special characters, such as quotation marks and backslashes, escaping may be necessary to avoid parsing errors. Use appropriate escaping rules, such as replacing double quotation marks with \".

[0083] Other special processing: Depending on business needs, formatting, standardization, or regular expression matching may be required.

[0084] Step 3: Adjust the preprocessed declaration configuration message according to the business logic of the e-commerce platform to obtain the adjusted declaration configuration message.

[0085] Write logic processing functions for the e-commerce platform's business rules, including but not limited to order number mapping, package quantity processing, and address deduplication.

[0086] Order ID Mapping: Depending on the requirements of the e-commerce platform, it may be necessary to map the original order number to a new order number that conforms to a specific format. This may involve generating a unique identifier (UUID), adding a prefix or suffix, etc.

[0087] Package Counting: Determine how many packages should be generated for each order. This may depend on the quantity and type of goods, or logistics requirements. For single orders containing multiple packages, sub-orders or tracking numbers may need to be created.

[0088] Address deduplication: Addresses are standardized and validated using a Geographic Information System (GIS). GIS identifies and removes duplicate addresses, ensuring data accuracy and consistency.

[0089] Step 4: Convert the adjusted declaration configuration message into a declaration configuration message in the format specified by the target customs, such as the XML format required by customs.

[0090] Use regular expressions or string replacement methods to automatically escape all special characters, ensuring that all XML special characters are correctly escaped to avoid parsing errors. The steps for escaping XML special characters are as follows: Check if the string contains XML special characters; use the escaping rules described above to replace the special characters with their escape forms. You can use string replacement or regular expressions to achieve this escaping, ensuring that the escaped string can be correctly parsed by the XML parser.

[0091] Step 5: Use the target customs-specified format parsing library to read the value mapping template and obtain the value mapping template under the target customs-specified format.

[0092] Based on the template file's format (e.g., XML, JSON, CSV), the corresponding parser is used to parse the file content, mapping the parsed data structure to the data fields required for customs declaration. For example, an XML parsing library is used to read the template file and parse it into an operable XML DOM structure, loading the XML-formatted customs message template. If customs declaration requirements change, the value mapping template is updated promptly, and testing and verification are performed again.

[0093] Step 6: Combine the XML compatibility parameters from Step 4 and the XML template from Step 5, fill the parameters into the template, and generate the declaration message.

[0094] The template is combined with actual business parameters for logical integration and data binding to generate a standardized message structure. The XML template is traversed, placeholders are found and replaced with the processed parameter values, and then the actual business parameter values ​​are replaced with the placeholders. The business parameters are then populated into the XML template to generate a complete message.

[0095] Step 7: Encrypt the declaration message.

[0096] The declaration message is encrypted according to the encryption method specified by the target customs authority, resulting in an encrypted message. The encrypted message is then digitally signed, resulting in a signed message. The message content is further encrypted according to customs settings, such as the configuration of the authentication machine. Pre-configured customs authentication machine settings are read and applied, and an encryption algorithm is applied according to the configuration to obtain the encrypted message.

[0097] Based on configuration or user input, select the data format and encryption method to construct personalized messages, including different formats (such as JSON / XML), different encryption methods, and different signature verification methods. By calling a built-in or externally integrated signature service, digitally sign the encrypted message to generate a legally valid digitally signed message. For example, use a digital signature library (such as OpenSSL) to generate the signature.

[0098] In the fourth stage, the encrypted declaration message is sent to the customs system.

[0099] Step 1: Send the encrypted message to the designated interface or server address of the customs system using the selected protocol.

[0100] Based on the requirements and security standards of the customs system, choose either HTTP or FTP protocol for message transmission. Construct an appropriate request format according to the selected sending method. For HTTP, this might be a POST request; for FTP, it might be an upload command.

[0101] Step 2: After receiving the message, the customs system decrypts it.

[0102] Step 3: The customs system verifies the format of the decrypted message to ensure it conforms to customs message specifications. It then further reviews the message content according to preset rules and standards to determine whether the declaration is approved.

[0103] Step 4: If the customs system returns a result indicating that corrections are needed, make the corresponding adjustments based on the feedback. If the declaration is approved, receive the response information from the customs system and proceed with subsequent operations.

[0104] Phase 5: Store any results returned by the customs system and the contents of the declaration messages in the database.

[0105] Collect all necessary data from the customs system's responses, including but not limited to declaration status, error messages, and timestamps. Format the collected data into a database-appropriate format, such as JSON, XML, or key-value pairs. By storing the results returned by the customs system and the contents of the declaration messages in a database, import and export operations can be better managed and analyzed, while ensuring data persistence and traceability.

[0106] In summary, this application provides a customs declaration method that, in response to an order declaration request from an e-commerce platform, obtains the corresponding target customs declaration configuration information based on the order declaration request; constructs a declaration message from the declaration configuration information by calling a message type template and a value mapping template; encrypts the declaration message and sends it to the customs declaration system, enabling the customs declaration system to decrypt and verify the declaration. Using message type templates and value mapping templates to construct the declaration message flexibly adapts to the requirements of different customs authorities, ensuring data accuracy and consistency. Encrypting the declaration message protects sensitive information, preventing unauthorized access or tampering during transmission, thus improving the accuracy and efficiency of customs declaration.
