returned data packets, for example, XML, Vector, Hashtable, or Map can be returned. The returned data is of the Vector type, so step 1 is encapsulated. Assemble SQL statements and create a class (XMLCombine) independently. of course, there can also be multiple classes, such as SelectCombine and insertCombine. here we perform unified encapsulation. Database operations are encapsulated into a separate class, XMLExecuteSQL. All the preceding classes have a uniform export class, which is XMLUtils.

Then we can use it very simply, when we modify the Actions.js import axios from '
