[0051] A method for dynamically acquiring exchange rates based on cross-border business, the method involving a business end, a scheduling end, a data end and a bank open platform, the method comprising:

[0052] S110, when the data end receives the task processing request sent by the scheduling end, the data end generates an acquisition instruction according to the task processing request, and sends the acquisition instruction to the bank open platform; wherein the bank open platform is used to obtain the daily exchange rates corresponding to all foreign currencies according to the acquisition instruction, and send the daily exchange rates corresponding to all foreign currencies to the data end;

When the data end receives the exchange rate acquisition request sent by the service end, the data end acquires target exchange rate data from the exchange rate data corresponding to each foreign exchange according to the exchange rate acquisition request, and sends the target exchange rate data to the service end.

[0055] In the embodiments of the present application, compared with the prior art that "manual maintenance of exchange rate data is inaccurate and untimely, which can easily lead to asset losses; different business scenarios require exchange rates of different dimensions, and manual maintenance workload is large and inefficient", the present application provides a solution of "a method for dynamically acquiring exchange rates based on cross-border business", specifically: "When the data end receives the task processing request sent by the scheduling end, the data end generates an acquisition instruction according to the task processing request, and sends the acquisition instruction to the bank open platform; wherein the bank open platform is used to obtain the daily exchange rate corresponding to all foreign currencies according to the acquisition instruction, and send the daily exchange rate corresponding to all foreign currencies to the data end; the data end performs persistent processing on the daily exchange rate corresponding to all foreign currencies to obtain the exchange rate data corresponding to each foreign exchange; when the data end receives the exchange rate acquisition request sent by the business end, the data end obtains the target exchange rate data from the exchange rate data corresponding to each foreign exchange according to the exchange rate acquisition request, and sends the target exchange rate data to the business end". Through the "data end", the problems of "inaccurate and untimely manual maintenance of exchange rate data, which can easily lead to capital loss; different business scenarios require exchange rates of different dimensions, and the workload of manual maintenance is large and inefficient" were solved, achieving the effect of "improving the accuracy and timeliness of exchange rate data; automatically pulling exchange rates reduces the cost of manual maintenance of exchange rate data; reducing customers' capital loss problems, reducing customer inquiries on exchange rate issues, and improving customer satisfaction".

[0056] Next, a method for dynamically acquiring exchange rates based on cross-border business in this exemplary embodiment will be further described.

[0057] It should be noted that foreign exchange refers to the flow of currencies between countries and the exchange of one country's currency into another country's currency to settle international creditor's rights and debts. It is the abbreviation of international exchange.

[0058] It should be noted that the spot purchase price refers to the price at which the bank buys the foreign currency spot from the customer, and is used when the customer converts the foreign currency spot he holds into RMB (settlement of foreign exchange).

[0059] It should be noted that the cash purchase price refers to the price at which a bank buys foreign currency cash from customers, and is used when customers exchange their foreign currency cash into RMB (exchange settlement).

[0060] It should be noted that the spot selling price refers to the price at which a bank sells foreign currency spot to a customer, and is used when a customer converts the RMB he holds into foreign currency spot (selling foreign exchange).

[0061] It should be noted that the cash selling price refers to the price at which a bank sells foreign currency cash to customers, and is used when customers exchange the RMB they hold into foreign currency cash (selling foreign exchange).

[0062] It should be noted that the Bank of China conversion price is a term in foreign exchange speculation. The Bank of China conversion price is equivalent to the benchmark price. If there is no benchmark price, the Bank of China converts the middle price by itself. The Bank of China conversion rate is the middle price used internally by the Bank of China and has no effect on general customers. It is mainly used for conversion between currencies during internal accounting, and is also used for internal closing of foreign exchange purchases to calculate the profit and loss of the business.

[0063] In one embodiment of the present invention, the step of acquiring the daily exchange rates corresponding to all foreign currencies according to the acquisition instruction, and sending the daily exchange rates corresponding to all foreign currencies to the data terminal includes:

[0064] The data terminal sends the acquisition instruction to the open interface of the bank open platform;

[0065] When the bank interface receives the acquisition instruction, the data terminal receives the daily exchange rates corresponding to all the foreign currencies sent by the bank open platform through the open interface.

[0066] It should be noted that the bank open platform refers to the Bank of China. The task scheduling system periodically triggers the master data system to obtain exchange rate data from the Bank of China interface and persist it in the system database.

[0067] As an example, the data end sends an acquisition instruction to the open interface of the Bank of China, and the open interface obtains the daily exchange rates corresponding to all foreign currencies according to the received acquisition instruction.

[0068] In a specific implementation, the exchange rate data is obtained from the Bank of China interface.

[0069] In one embodiment of the present invention, the step of performing persistent processing on the daily exchange rates corresponding to all the foreign currencies to obtain exchange rate data corresponding to each foreign currency includes:

[0070] When the data terminal receives the exchange rate of the day, the data terminal performs data preprocessing on the exchange rate of the day to generate processed data;

[0071] The data end determines the key fields of the processed data according to the processed data and a preset database;

[0072] The data end generates an information table for storing the key field in the preset database according to the key field;

[0073] The data end generates a database transaction according to the information table;

[0074] The data end writes the current day's exchange rate into the information table according to the database transaction to generate the exchange rate data.

[0075] It should be noted that after receiving the daily exchange rates of all foreign exchange currencies returned by the bank, the data end will first parse these daily exchange rates. The parsing process includes confirming whether the data is complete, accurate and in the expected format. At the same time, the data will be preliminarily sorted, such as classifying the daily exchange rates according to currency pairs (such as USD / RMB, EUR / RMB, etc.) for subsequent processing and storage.

[0076] It should be noted that the data terminal will establish a connection with the preset database. This preset database is specifically used to store exchange rate data, including historical exchange rate information and current exchange rate information. After connecting to the preset database, the data terminal will check the current status of the preset database, such as whether there is a mismatch in the table structure, whether the preset database connection is normal, and other issues, and prepare to write data to the preset database.

[0077] It should be noted that once the data end confirms that the data parsing and the preset database connection are correct, it will start writing the parsed processed data into the preset database. This process is usually implemented through SQL statements or the API provided by the preset database. At the same time, in order to optimize the subsequent data query speed, the data end will also create indexes for the processed data in the preset database, such as indexing by currency pairs, dates, and other fields.

[0078] It should be noted that after the processed data is written into the preset database, the data end will also perform data verification and consistency checks. This process includes checking whether the written processed data is consistent with the original data, whether there are problems such as data loss or duplication. If the processed data is found to be inconsistent or has problems, the data end will perform corresponding processing, such as re-requesting data, correcting erroneous data, etc.

[0079] It should be noted that when all processed data is successfully written to the preset database and has been verified and checked for consistency, the data end will mark the task as completed and record relevant log information. These log information include the task processing time, processing results, possible problems, etc., to facilitate subsequent troubleshooting and performance optimization.

[0080] As an example, after receiving the exchange rate of the day returned by the bank's open platform, the data end first performs data preprocessing. This includes verifying the integrity of the data, that is, checking whether there are missing exchange rates of the day, accuracy, that is, checking whether the exchange rate value is within a reasonable range, and format consistency, that is, ensuring that all data follows the same format standard; if errors or inconsistencies are found in the data preprocessing stage, the data end will perform data cleaning operations; data cleaning operations include correcting incorrect exchange rate values, deleting duplicate data records, or filling missing data; the data end maps the cleaned processed data to the corresponding fields in the preset database; this usually involves classifying the processed data according to key fields such as currency pairs and dates, and preparing to insert them into specific tables in the preset database; before actual data persistence, the data end needs to establish a connection with the preset database and start a database transaction. This ensures that if any errors occur during the data persistence process, all executed database operations can be rolled back to maintain data consistency; in the context of the database transaction, the data end writes the processed data to the corresponding table in the preset database. This is usually achieved by executing SQL INSERT or UPDATE statements. If the preset database supports batch insert operations, the data end may choose to insert multiple processing data at one time to improve efficiency. After the data is successfully persisted to the preset database, the data end may create indexes for the information tables in the preset database according to business needs to speed up subsequent data queries. In addition, other performance optimization measures for the preset database can also be considered, such as adjusting the table structure, optimizing query statements, etc. Finally, the data end will commit the database transaction and record the log information related to this data persistence operation. This log information may include the start time, end time, success or failure status, exchange rate data involved, etc. This information is very important for subsequent troubleshooting, performance monitoring, and auditing.

[0081] In a specific implementation, after receiving the daily exchange rate information corresponding to all foreign currencies from the open interface of the Bank of China, the data end first performs data verification; this includes checking the integrity of the data (ensuring that all expected exchange rate information has been received), accuracy (verifying whether the exchange rate value is within a reasonable range and has no abnormal fluctuations), and timeliness of the data (confirming that the data is the latest exchange rate of the day); if the data verification passes, the data end will preprocess the received exchange rate information. This may include data format conversion (such as converting data in JSON or XML format to a format acceptable to the database), data cleaning (removing unnecessary fields or information), and data mapping (mapping the exchange rate information to the corresponding fields in the database table structure); the data end establishes a connection with the database and prepares for data persistence operations. This includes selecting the correct database instance, confirming the validity of the database connection, and creating or updating the database table structure as needed (such as adding new exchange rate data columns, adjusting indexes, etc.). In the context of the database connection, the data end writes the preprocessed exchange rate information into the corresponding table of the database. This usually involves executing a SQL INSERT statement (for new data) or an UPDATE statement (for existing data that needs to be updated). To ensure the integrity and consistency of the data, the data end may use database transactions to manage this series of operations. After the exchange rate information is persisted, the data end may need to index the database table to improve the efficiency of subsequent data queries. This includes creating or updating indexes (such as indexes based on currency pairs, dates, and other fields), and performing necessary query optimizations (such as adjusting query statements, using caches, etc.). After the data persistence operation is completed, the data end will commit the database transaction to ensure that all changes have been successfully applied to the database. At the same time, the data end will record log information related to this data persistence operation, including the start time, end time, amount of data involved, success, etc. of the operation. These log information are crucial for subsequent troubleshooting, performance monitoring, and auditing. In some cases, the data end may also need to synchronize the newly persisted exchange rate data to other systems or components (such as the business end, cache system, etc.) and notify related systems or components to update the data. This can be achieved through message queues, API calls, or other synchronization mechanisms. Through the above steps, the data end can ensure that the daily exchange rate obtained from the Bank of China interface is accurately and efficiently persisted in the system database, providing reliable and timely exchange rate information support for the business end; through such a persistence processing process, the data end can ensure that the daily exchange rates corresponding to all foreign currencies are accurately stored in the database for subsequent query and use by the business end.
