## AuthenticatorCallback<sup>8+</sup>

Provides methods for managing the OAuth authenticator callback.

### onResult<sup>8+</sup>

onResult: (code: number, result: {[key: string]: any}) =&gt; void

Called back to send the authentication result.

**System capability**: SystemCapability.Account.AppAccount

**Parameters**
 | Name | Type | Mandatory | Description |
 | ------ | -------------------- | ---- | ------ |
 | code | number | Yes | Authentication result code. |
 | result | {[key: string]: any} | Yes | Authentication result. |

**Example**

  ```js
  const appAccountManager = account_appAccount.createAppAccountManager();
  var sessionId = "1234";
  appAccountManager.getAuthenticatorCallback(sessionId).then((callback) => {
      var result = {[account_appAccount.Constants.KEY_NAME]: "LiSi",
                    [account_appAccount.Constants.KEY_OWNER]: "com.example.ohos.accountjsdemo",
                    [account_appAccount.Constants.KEY_AUTH_TYPE]: "readAge",
                    [account_appAccount.Constants.KEY_TOKEN]: "xxxxxx"};
      callback.OnResult(account_appAccount.ResultCode.SUCCESS, result);
  }).catch((err) => {
      console.log("getAuthenticatorCallback err: "  + JSON.stringify(err));
  });
  ```

### onRequestRedirected<sup>8+</sup>

onRequestRedirected: (request: Want) =&gt; void

Called back to redirect an authentication request.

**System capability**: SystemCapability.Account.AppAccount

**Parameters**
 | Name | Type | Mandatory | Description |
 | ------- | ---- | ---- | ---------- |
 | request | Want | Yes | Request to be redirected. |

**Example**

  ```js
  class MyAuthenticator extends account_appAccount.Authenticator {
      addAccountImplicitly(authType, callerBundleName, options, callback) {
          callback.onRequestRedirected({
              bundleName: "com.example.ohos.accountjsdemo",
              abilityName: "com.example.ohos.accountjsdemo.LoginAbility",
          });
      }

      authenticate(name, authType, callerBundleName, options, callback) {
          var result = {[account_appAccount.Constants.KEY_NAME]: name,
                        [account_appAccount.Constants.KEY_AUTH_TYPE]: authType,
                        [account_appAccount.Constants.KEY_TOKEN]: "xxxxxx"};
          callback.onResult(account_appAccount.ResultCode.SUCCESS, result);
      }
  }
  ```

## Authenticator<sup>8+</sup>

Defines the OAuth authenticator base class.

### addAccountImplicitly<sup>8+</sup>

addAccountImplicitly(authType: string, callerBundleName: string, options: {[key: string]: any}, callback: AuthenticatorCallback): void

Implicitly adds an app account based on the specified authentication type and options. This method uses an asynchronous callback to return the result.

 | authType | string | Yes | Authentication type. |
 | callerBundleName | string | Yes | Bundle name of the authentication requester. |

 | callback | AuthenticatorCallback | Yes | Authenticator callback invoked to return the authentication result. |

### authenticate<sup>8+</sup>

authenticate(name: string, authType: string, callerBundleName: string, options: {[key: string]: any}, callback: AuthenticatorCallback): void

Authenticates an app account to obtain the OAuth access token. This method uses an asynchronous callback to return the result.

**System capability**: SystemCapability.Account.AppAccount

**Parameters**
 | Name | Type | Mandatory | Description |
 | ---------------- | --------------------- | ---- | --------------- |
 | name | string | Yes | App account name. |
 | authType | string | Yes | Authentication type. |
 | callerBundleName | string | Yes | Bundle name of the authentication requester. |
 | options | {[key: string]: any} | Yes | Options for the authentication. |
 | callback | AuthenticatorCallback | Yes | Authenticator callback invoked to return the authentication result. |

**Example**

  ```js
  class MyAuthenticator extends account_appAccount.Authenticator {
      addAccountImplicitly(authType, callerBundleName, options, callback) {
          callback.onRequestRedirected({
              bundleName: "com.example.ohos.accountjsdemo",
              abilityName: "com.example.ohos.accountjsdemo.LoginAbility",
          });
      }

      authenticate(name, authType, callerBundleName, options, callback) {
          var result = {[account_appAccount.Constants.KEY_NAME]: name,
                        [account_appAccount.Constants.KEY_AUTH_TYPE]: authType,
                        [account_appAccount.Constants.KEY_TOKEN]: "xxxxxx"};
          callback.onResult(account_appAccount.ResultCode.SUCCESS, result);
      }
  }

  export default {
      onConnect(want) {
