- Configure the cloud database. Add the network permission to the entry/src/main/module.json5 file.
"requestPermissions": [ { "name": "ohos.permission.INTERNET" } ] - To use Cloud DB, you need to obtain user credentials through AuthProvider. You can use the access token API of Account Kit to customize an AuthProvider.
- In the service code, use the QuickStartDemo class of the Cloud DB zone created in AppGallery Connect to initialize DatabaseZone.
import { cloudDatabase } from '@kit.CloudFoundationKit'; let databaseZone = cloudDatabase.zone('QuickStartDemo'); - To use the database query method, use the BookInfo class to initialize DatabaseQuery.
import { BookInfo } from 'xx/BookInfo'; // xx is the path to the BookInfo file. let condition = new cloudDatabase.DatabaseQuery(BookInfo);
You can create databaseZone and condition objects, which will be used in each query, by referring to this section. The following code will not describe the creation process again.
