# Account Subsystem ChangeLog

## cl.account_os_account.1 Change of Definition and Return Mode of Error Codes

To solve the issues that error code definitions of the account subsystem APIs were inconsistent and that the return mode of the error codes did not comply with relevant specifications of OpenHarmony, the following changes are made and take effect in API version 9 and later:

- Added the following unified error code definitions:
  - [Account Error Codes](https://gitee.com/openharmony/docs/blob/master/en/application-dev/reference/errorcodes/errorcode-account.md)
  - [App Account Error Codes](https://gitee.com/openharmony/docs/blob/master/en/application-dev/reference/errorcodes/errorcode-account.md)

- Returned an error code in either of the following ways, according to the API type:
  - Asynchronous API: An error message is returned via **AsyncCallback** or the **error** object of **Promise**. An error message related to the parameter type or quantity is returned via an exception.
  - Synchronous API: An error message is returned via an exception.

**Change Impacts**

The application developed based on earlier versions needs to adapt the method for returning API error information. Otherwise, the original service logic will be affected.

**Key API/Component Changes**

The mentioned changes involve the following APIs:
  - class AccountManager
    - activateOsAccount(localId: number, callback: AsyncCallback<void>): void;
    - removeOsAccount(localId: number, callback: AsyncCallback<void>): void;
    - setOsAccountConstraints(localId: number, constraints: Array<string>, enable: boolean, callback: AsyncCallback<void>): void;
    - setOsAccountName(localId: number, localName: string, callback: AsyncCallback<void>): void;
    - queryMaxOsAccountNumber(callback: AsyncCallback<number>): void;
    - queryAllCreatedOsAccounts(callback: AsyncCallback<Array<OsAccountInfo>>): void;
    - createOsAccount(localName: string, type: OsAccountType, callback: AsyncCallback<OsAccountInfo>): void;
    - createOsAccountForDomain(type: OsAccountType, domainInfo: DomainAccountInfo, callback: AsyncCallback<OsAccountInfo>): void;
    - queryOsAccountById(localId: number, callback: AsyncCallback<OsAccountInfo>): void;
    - getOsAccountProfilePhoto(localId: number, callback: AsyncCallback<string>): void;
    - setOsAccountProfilePhoto(localId: number, photo: string, callback: AsyncCallback<void>): void;
    - on(type: 'activate' | 'activating', name: string, callback: Callback<number>): void;
    - off(type: 'activate' | 'activating', name: string, callback?: Callback<number>): void;
    - isMainOsAccount(callback: AsyncCallback<boolean>): void;
    - queryOsAccountConstraintSourceTypes(localId: number, constraint: string, callback: AsyncCallback<Array<ConstraintSourceTypeInfo>>): void;
  - class UserAuth
    - constructor();
    - getVersion(): number;
    - getAvailableStatus(authType: AuthType, authTrustLevel: AuthTrustLevel): number;
    - getProperty(request: GetPropertyRequest, callback: AsyncCallback<ExecutorProperty>): void;
    - setProperty(request: SetPropertyRequest, callback: AsyncCallback<number>): void;
    - auth(challenge: Uint8Array, authType: AuthType, authTrustLevel: AuthTrustLevel, callback: IUserAuthCallback): Uint8Array;
    - authUser(userId: number, challenge: Uint8Array, authType: AuthType, authTrustLevel: AuthTrustLevel, callback: IUserAuthCallback): Uint8Array;
    - cancelAuth(contextID: Uint8Array): number;
  - class PINAuth
    - constructor();
    - registerInputer(inputer: IInputer): boolean;
    - unregisterInputer(authType: AuthType): void;
  - class UserIdentityManager
    - constructor();
    - openSession(callback: AsyncCallback<Uint8Array>): void;
    - addCredential(credentialInfo: CredentialInfo, callback: IIdmCallback): void;
    - updateCredential(credentialInfo: CredentialInfo, callback: IIdmCallback): void;
    - closeSession(): void;
    - cancel(challenge: Uint8Array): number;
    - delUser(token: Uint8Array, callback: IIdmCallback): void;
    - delCred(credentialId: Uint8Array, token: Uint8Array, callback: IIdmCallback): void;
    - getAuthInfo(callback: AsyncCallback<Array<EnrolledCredInfo>>): void;
  - interface IInputData
    - onSetData: (authSubType: AuthSubType, data: Uint8Array) => void;

**Adaptation Guide**

The following uses **activateOsAccount** as an example to illustrate the error information processing logic of an asynchronous API:

```ts
import account_osAccount from "@ohos.account.osAccount"
let accountMgr = account_osAccount.getAccountManager()
let callbackFunc = (err) => {
  if (err != null) {  // Handle the business error.
    console.log("account_osAccount failed, error: " + JSON.stringify(err));
  } else {
    console.log("account_osAccount successfully");
  }
}
try {
  accountMgr.activateOsAccount("100", callbackFunc);
} catch (err) {  // Process the error that is related to the parameter type.
  console.log("account_osAccount failed for incorrect parameter type, error: " + JSON.stringify(err));
}
try {
  accountMgr.activateOsAccount();
} catch (err) {  // Process the error that is related to the parameter quantity.
  console.log("account_osAccount failed for incorrect parameter number, error: " + JSON.stringify(err));
}
```

The following uses **registerInputer** as an example to illustrate the error information processing logic of a synchronous API:

```ts
import account_osAccount from "@ohos.account.osAccount"
let pinAuth = new account_osAccount.PINAuth()
try {
    pinAuth.registerInputer({})
} catch (err) {  // Process the error that is related to the parameter type.
  console.log("account_osAccount failed for incorrect parameter type, error: " + JSON.stringify(err));
}
try {
    pinAuth.registerInputer()
} catch (err) {  // Process the error that is related to the parameter quantity.
  console.log("account_osAccount failed for incorrect parameter number, error: " + JSON.stringify(err));
}
```
