}Since the bank exchange rate changes are not real-time, the API of this project does caching and the default is 300 seconds.
For example, the first time to get the dollar exchange rate, the API of this project needs to get the data from the third-party API, which may take 300ms, and the second time to get the dollar exchange rate within 300 seconds only takes 2-3ms.
