| 9200001  | The application is not an administrator application of the device. |
| 9200002  | The administrator application does not have permission to manage the device. |
| 201      | Permission verification failed. The application does not have the permission required to call the API. |

**示例：**

```ts
import { Want } from '@kit.AbilityKit';

let wantTemp: Want = {
  bundleName: 'com.example.myapplication',
  abilityName: 'EntryAbility',
};
let domainFilterRule: networkManager.DomainFilterRule = {
  "domainName": "www.example.com",
  "appUid": "9696",
  "action": networkManager.Action.DENY,
}

networkManager.addDomainFilterRule(wantTemp, domainFilterRule);
```

## networkManager.removeDomainFilterRule

removeDomainFilterRule(admin: Want, domainFilterRule?: DomainFilterRule): void

指定设备管理应用移除设备域名过滤规则。<br/>
移除规则后如果不存在[Action](#action)为ALLOW规则后，会将[addDomainFilterRule](#networkmanageradddomainfilterrule)添加的默认DENY规则清空。
