Managing Application Accounts

You can use the application account SDK to manage application accounts.

When an application is uninstalled, the account data of the application will be automatically deleted. When a local account is deleted, the account data of all applications of the local account will be automatically deleted.

Before You Start

Import the appAccount module.

   import { appAccount, BusinessError } from '@kit.BasicServicesKit';

Obtain an AppAccountManager instance.

   const appAccountManager = appAccount.createAppAccountManager();

Creating an Application Account

Create an application account for an application user.

Procedure

Specify the account name and optional parameters.

   let name: string = "ZhangSan";
   let options: appAccount.CreateAccountOptions = {
     customData: {
       age: '10'
     }
   };

Use createAccount to create an application account based on the specified parameters.

   try {
     await appAccountManager.createAccount(name, options);
     console.log('createAccount successfully');
   } catch (err) {
     console.log('createAccount failed, error: ' + JSON.stringify(err));
   }

Obtaining Application Account List

Procedure

Use getAllAccounts to obtain the application account list.

   appAccountManager.getAllAccounts().then((data: appAccount.AppAccountInfo[]) => {
       console.debug('getAllAccounts successfully, data: ' + JSON.stringify(data));
   }).catch((err: BusinessError) => {
       console.debug('getAllAccounts failed, error: ' + JSON.stringify(err));
   });

Accessing Account Credentials

Procedure

Specify the account name, credential type, and credential.

   let name: string = 'ZhangSan';
   let credentialType: string = 'PIN_SIX';
   let credential: string = 'xxxxxx';

Use getCredential to obtain the account credential.

   appAccountManager.getCredential(name, credentialType).then((data: string) => {
       console.log('getCredential successfully, data: ' + data);
   }).catch((err: BusinessError) => {
       console.log('getCredential failed, error: ' + JSON.stringify(err));
   });

Use setCredential to set the account credential.

   appAccountManager.setCredential(name, credentialType, credential).then(() => {
       console.log('setCredential successfully');
   }).catch((err: BusinessError) => {
       console.log('setCredential failed: ' + JSON.stringify(err));
   });

Accessing Custom Account Data

Procedure

Specify the account name and custom data.

   let name: string = 'ZhangSan';
   let key: string = 'age';
   let value: string = '12';

Use setCustomData to customize account data.

   appAccountManager.setCustomData(name, key, value).then(() => {
       console.log('setCustomData successfully');
   }).catch((err: BusinessError) => {
       console.log('setCustomData failed: ' + JSON.stringify(err));
   });

Use getCustomData to obtain the custom account data.

   appAccountManager.getCustomData(name, key).then((data: string) => {
       console.log('getCustomData successfully, data: ' + data);
   }).catch((err: BusinessError) => {
       console.log('getCustomData failed, error: ' + JSON.stringify(err));
   });

Accessing the Account Authentication Token

Procedure

Specify the account name, account owner, authorization type, and authentication token.

   let name: string = 'ZhangSan';
   let owner: string = 'com.example.accountjsdemo';
   let authType: string = 'getSocialData';
   let token: string = 'xxxxxx';

Use setAuthToken to set an authorization token for the specified authentication type.

   appAccountManager.setAuthToken(name, authType, token).then(() => {
       console.log('setAuthToken successfully');
   }).catch((err: BusinessError) => {
       console.log('setAuthToken failed: ' + JSON.stringify(err));
   });

Use getAuthToken to obtain the authentication token of the specified authentication type.

   appAccountManager.getAuthToken(name, owner, authType).then((data: string) => {
       console.log('getAuthToken successfully, data: ' + data);
   }).catch((err: BusinessError) => {
       console.log('getAuthToken failed, error: ' + JSON.stringify(err));
   });

Removing an Application Account

Remove the application account after the user logs out of the system.

Procedure

Use removeAccount to remove the application account.

   let name: string = 'Zhangsan';
   appAccountManager.removeAccount(name).then(() => {
       console.log('removeAccount successfully');
   }).catch((err: BusinessError) => {
       console.log('removeAccount failed, error: ' + JSON.stringify(err));
   });
