@ohos.enterprise.browser (Browser Management) (System API)

The browser module provides browser management, including setting, canceling, and obtaining browser policies.

NOTE

The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.

The APIs of this module can be used only in the stage model.

The APIs of this module can be called only by a device administrator application that is enabled.

This topic describes only the system APIs provided by the module. For details about its public APIs, see @ohos.enterprise.browser.

Modules to Import

import { browser } from '@kit.MDMKit';

browser.setPolicies

setPolicies(admin: Want, appId: string, policies: string, callback: AsyncCallback<void>): void

Sets the browsing policy for a specified browser. This API uses an asynchronous callback to return the result.

Required permissions: ohos.permission.ENTERPRISE_SET_BROWSER_POLICY

System capability: SystemCapability.Customization.EnterpriseDeviceManager

Parameters

Name	Type	Mandatory	Description
admin	Want	Yes	EnterpriseAdminExtensionAbility.
appId	string	Yes	Application ID, which is used to specify the browser.
policies	string	Yes	Policies to set. If this parameter is set to an empty string, the policies of the specified browser are canceled.
callback	AsyncCallback<void>	Yes	Callback invoked to return the result. If the operation is successful, err is null. Otherwise, err is an error object.

Error codes

For details about the error codes, see Enterprise Device Management Error Codes and Universal Error Codes.

ID	Error Message
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.
202	Permission verification failed. A non-system application calls a system API.
401	Parameter error. Possible causes: 1. Mandatory parameters are left unspecified; 2. Incorrect parameter types; 3. Parameter verification failed.

Example

import { Want } from '@kit.AbilityKit';
let wantTemp: Want = {
  bundleName: 'com.example.myapplication',
  abilityName: 'EntryAbility',
};
// Replace the value of appId with the specified application ID of the browser.
let appId: string = 'com.example.******_******/******5t5CoBM=';
let policies: string = '{"InsecurePrivateNetworkRequestsAllowed":{"level":"mandatory","scope":"machine","source":"platform","value":true},"LegacySameSiteCookieBehaviorEnabledForDomainList":{"level":"mandatory","scope":"machine","source":"platform","value":["[*.]"]}}';
browser.setPolicies(wantTemp, appId, policies, (err) => {
  if (err) {
    console.error(`Failed to set browser policies. Code is ${err.code}, message is ${err.message}`);
    return;
  }
  console.info('Succeeded in setting browser policies.');
});

browser.setPolicies

setPolicies(admin: Want, appId: string, policies: string): Promise<void>

Sets the browsing policy for a specified browser. This API uses an asynchronous promise to return the result.

Required permissions: ohos.permission.ENTERPRISE_SET_BROWSER_POLICY

System capability: SystemCapability.Customization.EnterpriseDeviceManager

Parameters

Name	Type	Mandatory	Description
admin	Want	Yes	EnterpriseAdminExtensionAbility.
appId	string	Yes	Application ID, which is used to specify the browser.
policies	string	Yes	Policies to set. If this parameter is set to an empty string, the policies of the specified browser are canceled.

Return value

Type	Description
Promise<void>	Promise that returns no value. An error object is thrown when the browser policy fails to be set.

Error codes

For details about the error codes, see Enterprise Device Management Error Codes and Universal Error Codes.

ID	Error Message
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.
202	Permission verification failed. A non-system application calls a system API.
401	Parameter error. Possible causes: 1. Mandatory parameters are left unspecified; 2. Incorrect parameter types; 3. Parameter verification failed.

Example

import { Want } from '@kit.AbilityKit';
import { BusinessError } from '@kit.BasicServicesKit';
let wantTemp: Want = {
  bundleName: 'com.example.myapplication',
  abilityName: 'EntryAbility',
};
// Replace the value of appId with the specified application ID of the browser.
let appId: string = 'com.example.******_******/******5t5CoBM=';
let policies: string = '{"InsecurePrivateNetworkRequestsAllowed":{"level":"mandatory","scope":"machine","source":"platform","value":true},"LegacySameSiteCookieBehaviorEnabledForDomainList":{"level":"mandatory","scope":"machine","source":"platform","value":["[*.]"]}}';
browser.setPolicies(wantTemp, appId, policies).then(() => {
  console.info('Succeeded in setting browser policies.');
}).catch((err: BusinessError) => {
  console.error(`Failed to set browser policies. Code is ${err.code}, message is ${err.message}`);
});

browser.getPolicies

getPolicies(admin: Want, appId: string, callback: AsyncCallback<string>): void

Obtains the policy of the specified browser. This API uses an asynchronous callback to return the result.

System capability: SystemCapability.Customization.EnterpriseDeviceManager

Parameters
