更新安全管控策略

场景介绍

Enterprise Data Guard Kit为应用提供下发管控策略的能力，相关策略会被分发到HarmonyOS系统中执行。

接口说明

详细接口说明可参考接口文档。

接口名	描述
updatePolicy(policy: string, callback: AsyncCallback<void>): void	使用Callback方式更新安全管控策略。
updatePolicy(policy: string): Promise<void>	使用Promise方式更新安全管控策略。

开发步骤

1. 导入模块。

   import { fileGuard } from '@kit.EnterpriseDataGuardKit';
   import { BusinessError } from '@kit.BasicServicesKit';

2. 初始化FileGuard对象guard，调用接口updatePolicy，更新安全管控策略。

   • 通过回调函数方式，更新安全管控策略。

     function updatePolicyCallback() {
       let guard: fileGuard.FileGuard = new fileGuard.FileGuard();
       let policy: string = '{' +
         '"net_intercept_toggle":1,' +
         '"default_policy":1,' +
         '"net_reject_cache_time":30,' +
         '"boundary":["10.0.0.0-10.255.255.255","172.16.0.0-172.31.255.255"],' +
         '"netsegment_trustlist":["10.0.0.0-10.255.255.255"],' +
         '"netsegment_blocklist":["172.16.0.0-172.31.255.255","192.168.0.0-192.168.255.255"],' +
         '"netsegment_update_type": 0,' +
         '"usb_intercept_toggle":1,' +
         '"smb_client_intercept_toggle":1,' +
         '"smb_server_intercept_toggle":1,' +
         '"new_file_audit_toggle":1,' +
         '"kia_variant_toggle":1,' +
         '"audit_filter_toggle":1,' +
         '"bluetooth_intercept_toggle":["bt_socket","bt_ble","bt_opp"],' +
         '"bluetooth_intercept_time":30,' +
         '"nearlink_intercept_toggle":["nearlink_ssap","nearlink_dataTransfer"],' +
         '"nearlink_intercept_time":30,' +
         '"trust_app_list":["ohos.app.hap.myapplication_BPch04bPYBrkJX8RAsmiGDbHFaG+BYvhkg4TK4fHQzJOL4VnoBCZU3boBBXGVEB+M/j0X2nnd7KVeyWuEORVxI2g="],' +
         '"Tag1":{' +
         '   "tag":"sensitive",' +
         '   "usb_intercept_toggle":1,' +
         '   "net_intercept_toggle":1,' +
         '   "boundary":["10.0.0.0-10.255.255.255"],' +
         '   "netsegment_trustlist":["10.0.0.0-10.255.255.255"],' +
         '   "netsegment_blocklist":["192.168.0.0-192.168.255.255"]' +
         '  }' +
         '}';
       guard.updatePolicy(policy, (err: BusinessError) => {
         if (err) {
           console.error(`Failed to update policy. Code: ${err.code}, message: ${err.message}.`);
         } else {
           console.info(`Succeeded in updating policy.`);
         }
       });
     }

   • 通过Promise方式，更新安全管控策略。

     function updatePolicyPromise() {
       let guard: fileGuard.FileGuard = new fileGuard.FileGuard();
       let policy: string = '{' +
         '"net_intercept_toggle":1,' +
         '"default_policy":1,' +
         '"net_reject_cache_time":30,' +
         '"boundary":["10.0.0.0-10.255.255.255","172.16.0.0-172.31.255.255"],' +
         '"netsegment_trustlist":["10.0.0.0-10.255.255.255"],' +
         '"netsegment_blocklist":["172.16.0.0-172.31.255.255","192.168.0.0-192.168.255.255"],' +
         '"netsegment_update_type": 0,' +
         '"usb_intercept_toggle":1,' +
         '"smb_client_intercept_toggle":1,' +
         '"smb_server_intercept_toggle":1,' +
         '"new_file_audit_toggle":1,' +
         '"kia_variant_toggle":1,' +
         '"audit_filter_toggle":1,' +
         '"bluetooth_intercept_toggle":["bt_socket","bt_ble","bt_opp"],' +
         '"bluetooth_intercept_time":30,' +
         '"nearlink_intercept_toggle":["nearlink_ssap","nearlink_dataTransfer"],' +
         '"nearlink_intercept_time":30,' +
         '"trust_app_list":["ohos.app.hap.myapplication_BPch04bPYBrkJX8RAsmiGDbHFaG+BYvhkg4TK4fHQzJOL4VnoBCZU3boBBXGVEB+M/j0X2nnd7KVeyWuEORVxI2g="],' +
         '"Tag1":{' +
         '   "tag":"sensitive",' +
         '   "usb_intercept_toggle":1,' +
         '   "net_intercept_toggle":1,' +
         '   "boundary":["10.0.0.0-10.255.255.255"],' +

         '  }' +
         '}';
       guard.updatePolicy(policy).then(() => {
         console.info(`Succeeded in updating policy.`);
       }).catch((err: BusinessError) => {
         console.error(`Failed to update policy. Code: ${err.code}, message: ${err.message}.`);
       });
     }
