管理分布式账号(仅对系统应用开放)

OEM厂商可以通过@ohos.account.distributedAccount将自有账号与本地系统账号建立关联关系。

开发准备

  1. 申请权限:ohos.permission.MANAGE_DISTRIBUTED_ACCOUNTS。申请流程请参考:申请应用权限

  2. 导入分布式账号模块。

    import { distributedAccount, BusinessError } from '@kit.BasicServicesKit';
    
  3. 获取分布式账号的单实例对象。

    const distributedAccountAbility = distributedAccount.getDistributedAccountAbility();
    

在当前系统账号上登录绑定分布式账号

具体开发实例如下:

  1. 定义待登录的分布式账号信息。其中,登录场景下需将event指定为"Ohos.account.event.LOGIN"。

     let distributedInfo: distributedAccount.DistributedInfo = {
       name: 'ZhangSan',
       id: '12345',
       event: 'Ohos.account.event.LOGIN',
     };
    
  2. 调用setOsAccountDistributedInfo接口,将当前系统账号与指定分布式账号绑定到一起。

     await distributedAccountAbility.setOsAccountDistributedInfo(distributedInfo).then(() => {
       console.info('setOsAccountDistributedInfo successfully');
     }).catch((err: BusinessError) => {
       console.error(`setOsAccountDistributedInfo exception: code is ${err.code}, message is ${err.message}`);
       // ···
     });
    
  3. 在账号绑定之后,可以调用getOsAccountDistributedInfo接口查看分布式账号的登录信息。

     distributedAccountAbility.getOsAccountDistributedInfo().then((data: distributedAccount.DistributedInfo) => {
       console.info('distributed information: ' + JSON.stringify(data));
       // ···
     }).catch((err: BusinessError) => {
       console.error(`getOsAccountDistributedInfo exception: code is ${err.code}, message is ${err.message}`);
       // ···
     });
    

在当前系统账号上登出解绑分布式账号

具体开发实例如下:

  1. 定义待登出的分布式账号信息。其中,登录场景下需将event指定为"Ohos.account.event.LOGOUT"。

     let distributedInfo: distributedAccount.DistributedInfo = {
       name: 'ZhangSan',
       id: '12345',
       event: 'Ohos.account.event.LOGOUT',
     };
    
  2. 调用setOsAccountDistributedInfo接口,将指定的分布式账号与当前系统账号解绑。

     distributedAccountAbility.setOsAccountDistributedInfo(distributedInfo).then(() => {
       console.info('setOsAccountDistributedInfo successfully');
       // ···
     }).catch((err: BusinessError) => {
       console.error(`setOsAccountDistributedInfo exception: code is ${err.code}, message is ${err.message}`);
       // ···
     });
    

在指定的系统账号上登录绑定分布式账号

具体开发实例如下:

  1. 确定目标系统账号,并定义待登录的分布式账号信息。其中,登录场景下需将event指定为"Ohos.account.event.LOGIN"。

     let localId: number = 100;
     let distributedInfo: distributedAccount.DistributedInfo = {
       name: 'ZhangSan',
       id: '12345',
       event: 'Ohos.account.event.LOGIN',
     };
    
  2. 调用setOsAccountDistributedInfoByLocalId接口,将指定分布式账号与当前系统账号绑定。

     await distributedAccountAbility.setOsAccountDistributedInfoByLocalId(localId, distributedInfo).then(() => {
       console.info('setOsAccountDistributedInfoByLocalId successfully');
     }).catch((err: BusinessError) => {
       console.error(`setOsAccountDistributedInfoByLocalId exception: code is ${err.code}, message is ${err.message}`);
       // ···
     });
    
  3. 在账号绑定之后,可以调用getOsAccountDistributedInfoByLocalId接口查看分布式账号的登录信息。

     distributedAccountAbility.getOsAccountDistributedInfoByLocalId(localId)
       .then((data: distributedAccount.DistributedInfo) => {
       console.info('distributed information: ' + JSON.stringify(data));
       // ···
     }).catch((err: BusinessError) => {
       console.error(`getOsAccountDistributedInfoByLocalId exception: code is ${err.code}, message is ${err.message}`);
       // ···
     });
    

在指定系统账号上登出解绑分布式账号

具体开发实例如下:

  1. 确定目标系统账号,并定义待登出的分布式账号信息。其中,登录场景下需将event指定为"Ohos.account.event.LOGOUT"。

     let localId: number = 100;
     let distributedInfo: distributedAccount.DistributedInfo = {
       name: 'ZhangSan',
       id: '12345',
       event: 'Ohos.account.event.LOGOUT',
     };
    
  2. 调用setOsAccountDistributedInfoByLocalId接口,将指定的分布式账号与目标系统账号解绑。

     distributedAccountAbility.setOsAccountDistributedInfoByLocalId(localId, distributedInfo).then(() => {
       console.info('setOsAccountDistributedInfoByLocalId successfully');
       // ···
     }).catch((err: BusinessError) => {
       console.error(`setOsAccountDistributedInfoByLocalId exception: code is ${err.code}, message is ${err.message}`);
       // ···
     });
