-## Before You Start<a name="section965173113911"></a>
-1.  Install DevEco Studio and configure the development environment. For details, see  [Configuring the OpenHarmony SDK](configuring-openharmony-sdk.md).
-2.  Create a project as instructed in  [Creating an OpenHarmony Project](create-openharmony-project.md).
-    -   If you are using the JavaScript language, select  **Empty Ability**  for  **Template**  and  **JS**  for  **Language**.
-3.  Use the  [previewer](https://developer.harmonyos.com/en/docs/documentation/doc-guides/previewer-0000001054328973#EN-US_TOPIC_0000001056725592__section16523172216252)  or  [emulator](https://developer.harmonyos.com/en/docs/documentation/doc-guides/run_simulator-0000001053303709)  to run the project.
-Now you have created your first OpenHarmony project. You can continue the development by following instructions in  [Getting Started with JavaScript](start-with-js.md).

-# Getting Started with JavaScript<a name="EN-US_TOPIC_0000001168007068"></a>
-For best results, use the  [latest version of DevEco Studio](https://developer.harmonyos.com/en/develop/deveco-studio#download)  for your development.
-## Building the First Page<a name="section1754373063820"></a>
-1.  Add a  **Text**  and a  **Button**  component to the first page.
-    In the  **Project**  window, choose  **entry**  \>  **src**  \>  **main**  \>  **js**  \>  **default**  \>  **pages**  \>  **index**, open the  **index.hml**  file, and add the components.
-    ```
-    <!-- index.hml -->
-    <div class="container">
-        <!-- Add text. -->
-        <text class="text">
-            Hello World
-        </text>
-        <!-- Add a button, set its type to capsule, set button text to Next, and bind it to the launch event. -->
-        <button class="button" type="capsule" value="Next" onclick="launch"></button>
-    </div>
-    ```
-2.  Open the  **index.css**  file and set text and button styles.
-    ```
-    /* index.css */
-    .container {
-        flex-direction: column; /* Arrange container items vertically. */
-        justify-content: center; /* Center the items along the main axis of the container. */
-        align-items: center; /* Center the items along the cross axis of the container. */
-        width:100%;
-        height:100%;
-    }
-    /* Set the style for the component of the text class. */
-    .text{
-        font-size: 42px;
-    }
-    /* Set the style for the component of the button class. */
-    .button {
-        width: 240px;

-    // index.js
-    import router from '@system.router';
-    export default {
-      launch() {
-        router.push ({
-          uri:'pages/details/details', // Specify the page to be redirected to.
-        })
-      }
-    }
-    ```

-## How to Develop<a name="section123181432175110"></a>
-### **C++**<a name="section2016116181902"></a>
-In this example, you'll be instructed to register a listener for all system events that belong to the  **HIVIEWDFX**  domain.
 1.  Develop the source code.
-    -   Import the corresponding header file:
+    Import the **DemoListener.h** header file, which contains the **DemoListener** class for implementing the custom event callback.
-        hisysevent\_manager.h
+    ```
+    #ifndef DEMO_LISTENER_H
+    #define DEMO_LISTENER_H
-    -   Implement the callback API.
+    #include "hisysevent_subscribe_callback.h"
-        HiSysEventSubscribeCallBack::OnHandle\(const std::string& domain, const std::string& eventName, const int eventType, const std::string& eventDetail\)
+    #include <string>
-    -   Register a callback object.
+    class DemoListener : public OHOS::HiviewDFX::HiSysEventSubscribeCallBackNative {
+    public:
+        explicit DemoListener() : HiSysEventSubscribeCallBackNative() {}
+        void OnHandle(const std::string& domain, const std::string& eventName, const int eventType,
+            const std::string& eventDetail);
+        virtual ~DemoListener() {}
+        void OnServiceDied();
+    };
-        HiSysEventManager::AddEventListener\(std::shared\_ptr<HiSysEventSubscribeCallBack\> listener, std::vector<struct ListenerRule\>& rules\)
+    #endif DEMO_LISTENER_H
+    ```
+    Create the **DemoListener.cpp** file, and add the implementation logic of the custom event callback API in the **DemoListener** class.
    ```
-    // Register a listener for all system events that belong to the HIVIEWDFX domain.
+    #include "demo_listener.h"
-    #include "hisysevent_manager.h"
    #include <iostream>
-    namespace OHOS {
-    namespace HiviewDFX {
+    void DemoListener::OnHandle(const std::string& domain, const std::string& eventName,
-    // Implement the API for registering a listener for callback objects.
-    void HiSysEventToolListener::OnHandle(const std::string& domain, const std::string& eventName,
        const int eventType, const std::string& eventDetail)
    {
        std::cout << eventDetail << std::endl;
    }
-    void HiSysEventToolListener::OnServiceDied()
+    void DemoListener::OnServiceDied()
    {
        std::cout << std::string("service disconnect, exit") << std::endl;
        exit(0);
    }
-    } // namespace HiviewDFX
-    } // namespace OHOS
-    // Register a listener for callback objects.
-    auto toolListener = std::make_shared<HiSysEventToolListener>();
-    struct ListenerRule rule;
-    rule.ruleType = 1; // 1: default type
-    rule.domain = "HIVIEWDFX";
-    std::vector<struct ListenerRule> sysRules;
-    sysRules.push_back(rule);
-    HiSysEventManager::AddEventListener(toolListener, sysRules);
    ```
-2.  Modify the  **BUILD.gn**  file.
+    Call the **AddEventListener** API of the **HiSysEventManager** class to add a listener for system events.
-    In the  **BUILD.gn**  file, add the  **libhisyseventmanager**  library that depends on the** hisysevent\_native**  component.
    ```
-    external_deps = [ "hisysevent_native:libhisyseventmanager",  ]
+    auto demoListener = std::make_shared<DemoListener>();
+    // Add a ListenerRule object based on the event tag, with RuleType left unspecified (in this case, ruleType is defaulted to WHOLE_WORD).
+    ListenerRule tagRule("dfx");
+    // Add a ListenerRule object based on the event tag, with RuleType set as REGULAR.
+    ListenerRule regRule("dfx.*", RuleType::REGULAR);
+    // Add a ListenerRule object based on the event domain and event name, with RuleType set as PREFIX.
+    ListenerRule domainNameRule("HIVIEWDFX", "APP_USAGE", RuleType::PREFIX);
+    std::vector<ListenerRule> sysRules;
+    sysRules.push_back(tagRule);
+    sysRules.push_back(regRule);
+    sysRules.push_back(domainNameRule);
+    HiSysEventManager::AddEventListener(demoListener, sysRules);
    ```
+2.  Configure the **BUILD.gn** file.
+    In the **BUILD.gn** file, add the **libhisyseventmanager** library that depends on the **hisysevent\_native** component.
+    ```
+    external_deps = [ "hisysevent_native:libhisyseventmanager", ]
+    ```

+## Overview<a name="section315316685115"></a>
+If HiSysEvent logging is required for a component, you need to define a YAML file and [configure the YAML file path](#section123181432175135) in the **bundle.js** file. During compilation, the OpenHarmony compilation framework will use the Python compilation script to parse and verify all the YAML files configured in the **bundle.js** file. On completion, the compilation framework will summarize the configuration information in the YAML files and convert the information into a JSON file named **hisysevent.def**. After that, the compilation framework will put the JSON file to a specified path as the basis for the system to determine whether to log system events.
+### Basic Concepts<a name="section123181432175143"></a>
+Understanding the following concepts would be helpful for you in configuring HiSysEvent logging.
+- Event domain
+  Represents the domain to which an event belongs. It is specified by the **domain** field in the YAML file. For details, see [domain](#section123181432175123) in the example YAML file.
+- Event name
+  Indicates the events in an event domain. For details, see [EVENT\_NAMEA/EVENT\_NAMEB](#section123181432175123) in the example YAML file.
+- Parameter
+  Defines the key values in an event name. For details, see [__BASE/NAME1/NAME2](#section123181432175123) in the example YAML file.
+### Constraints<a name="section123181432175114"></a>
+- Each YAML file can contain only one event domain, and the domain name cannot be the same as that defined in other YAML files.
+- Zero or more event names can be defined for one event domain. The event names in the same event domain must be unique.
+- Multiple parameters can be defined for one event name. The parameters in the same event name must be unique. There must be one and only one parameter named **\__BASE** in each event name. See Table 1 for the fields of this parameter and Table 2 for the fields of other custom parameters.
+  **Table 1** Fields in the \__BASE parameter
+  | Field| Description|
+  | ----- | ----- |
+  | type | Indicates the type of the event. This field is mandatory. <br><br>Value:<ul><li>**FAULT**: fault </li><li>**STATISTIC**: statistics </li><li>**SECURITY**: security </li><li>**BEHAVIOR**: user behavior</li></ul> |
+  | level | Indicates the level of the event. This field is mandatory. <br><br>Value: <ul><li>**CRITICAL**: critical </li><li>**MINOR**: minor</li></ul> |
+  | tag | Indicates the tag of the event. This field is mandatory. <br><br>Rule:<ul><li>You can define a maximum of five tags,separated with a space. </li><li>A single tag can contain a maximum of 16 characters, including a to z, A to Z, and 0 to 9.</li></ul>|
+  | desc | Describes the event name. This field is mandatory. <br><br>Rule:<ul><li>The description contains 3 to 128 characters, including a to z, A to Z, 0 to 9, and underscores (&#95;).</li></ul>|
+  **Table 2** Description of custom parameters
+  | Field| Description|
+  | ----- | ----- |

+## Writing a YAML File<a name="section123181432175113"></a>
+### Writing Rules<a name="section123181432175133"></a>
+-   Event domain naming rules:
+    -   The name must start with a letter and can contain only uppercase letters, digits, and underscores (&#95;).
+    -   The name contains 1 to 16 characters.
+-   Event naming rules:
+    -   The name must start with a letter and can contain only uppercase letters, digits, and underscores (&#95;).
+    -   The name contains 1 to 32 characters.
+    -   The number of internal event names in an event domain cannot exceed 4096.
+-   Parameter naming rules:
+    -   The name must start with a letter and can contain only uppercase letters, digits, and underscores (&#95;).
+    -   The name contains 1 to 32 characters.
+    -   The number of parameters in an event domain cannot exceed 128.
+### Example<a name="section123181432175123"></a>
+-   In the example YAML file, the event domain name is **MODULEA**. The event domain contains two events named **EVENT\_NAMEA** and **EVENT\_NAMEB**.
+-   **EVENT\_NAMEA** is defined as a critical event of the fault type. The event contains the **NAME1** parameter of the string type, the **NAME2** parameter of the string type, and the **NAME3** parameter of the unsigned short integer type. Therefore, you can perform [real-time subscription](subsys-dfx-hisysevent-listening.md) to the event based on the event domain **MODULEA** and event name **EVENT\_NAMEA**.
+-   **EVENT\_NAMEB** is defined as a general event of the statistics type. The event contains the **NAME1** parameter of the unsigned short integer type and the **NAME2** parameter of the integer type. Because two event tags named **tag1** and **tag2** are defined for **EVENT\_NAMEB** in the **\__BASE** parameter, you can perform [real-time subscription](subsys-dfx-hisysevent-read.md) to the event based on the event domain **MODULEA** and event name **EVENT\_NAMEB**, or based on the event tag.

+### Compiling the YAML File<a name="section123181432175137"></a>
+-   Perform full compilation.
+    -   During full compilation of the system, the configuration in the YAML files of all components are summarized. After the compilation is complete, the **hisysevent.def** file will be generated in the specified directory.
+    ```
+    cd absolute path of the project's root directory
+    ./build --product-name <product name>
+    ```
+    -   To obtain the **hisysevent.def** file generated after full compilation, run the following command:
+    ```
+    cd absolute path of the project's root directory
+    find out -name hisysevent.def -type f
+    ```
+-   Single-file compilation:
+    You can also compile the YAML file of a single component by running the following commands:
+    ```
+    cd absolute path of the project's root directory
+    ./build/ohos/hisysevent/gen_def_from_all_yaml.py --yaml-list <yaml file list> --def-path <file store directory>
+    ```
+  **Table 3** Parameters for single-file compilation
+  | Parameter| Description|
+  | ------ | ------ |
+  | --yaml-list | Specifies the paths of the YAML files to be compiled. If there are multiple YAML file paths, separate each of them with a space.|
+  | --def-path | Specifies the path of the **hisysevent.def** file generated after compilation.|
+### Logging and Querying Events<a name="section123181432175139"></a>
+1.  Push the **hisysevent.def** file to the **/system/etc/hiview/** directory of the device by using the [hdc_std tool](subsys-toolchain-hdc-guide.md).
+2.  Trigger logging of the custom system events in the YAML file. Then, run [hisysevent -l](subsys-dfx-hisysevent-tool.md) to query historical system events to find out if the logging of the custom system events is successful.

-2. 进入配置工程界面，Project Type选择Application，Language选择eTS，其他参数根据实际需要设置即可。
-   ![zh-cn_image_0000001238853759](figures/zh-cn_image_0000001238853759.png)
-## 编写第一个页面
-1. 工程创建完成后，在"Project"窗口，点击entry &gt; src &gt; main &gt; ets &gt; default &gt; pages，打开index.ets文件。
-   ![zh-cn_image_0000001213883165](figures/zh-cn_image_0000001213883165.png)
-2. 第一个页面由Flex容器组件、Text组件和Button组件构成。在index.ets中编写并设置页面组件的属性和样式，示例代码如下所示：
-   ```
-   @Entry
-   @Component
-   struct Index {
-     build() {
-         //Flex容器组件
-         Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
-           //Text组件
-           Text('Hello World')
-             .fontSize(60)
-             .fontWeight(500)
-           //Button组件
-           Button('Next')
-             .fontSize(40)
-             .fontWeight(500)
-             .width(280)
-             .height(60)
-         }
-         //容器整体宽高
-         .width('100%')
-         .height('100%')
-       }
-   }
-   ```
-3. 使用[预览器](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/previewer-0000001054328973#ZH-CN_TOPIC_0000001056725592__section16523172216252)运行项目，效果如下图所示：
-   ![zh-cn_image_0000001168898456](figures/zh-cn_image_0000001168898456.png)
-## 创建第二个页面
-1. 在"Project"窗口，打开entry &gt; src &gt; main &gt; ets &gt; default，右键点击pages文件夹，选择NeweTS Page，命名为details，单击回车键。创建完成后，可以看到pages文件夹下的文件目录结构如下：
-   ![zh-cn_image_0000001214043107](figures/zh-cn_image_0000001214043107.png)
-2. 第二个页面由Flex容器组件、Text组件构成。在details.ets中编写并设置页面组件的属性和样式，示例代码如下所示：
-   ```
-   @Entry
-   @Component
-   struct Details {
-     build() {
-       //Flex容器组件
-       Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
-         //Text组件
-         Text('Hi there')
-           .fontSize(60)
-           .fontWeight(500)
-       }
-       //容器整体宽高
-       .width('100%')
-       .height('100%')
-     }
-   }
-   ```
-## 实现页面跳转
-1. 打开第一个页面的index.ets文件，导入router模块，页面路由router根据页面的uri来找到目标页面，从而实现跳转。示例代码如下：
-   ```
-   //导入router模块
-   import router from '@system.router';
-   @Entry
-   @Component
-   struct Index {
-     build() {
-       //Flex容器组件
-       Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
-         //Text组件
-         Text('Hello World')
-           .fontSize(60)
-           .fontWeight(500)
-         //Button组件
-         Button('Next')
-           .fontSize(40)
-           .fontWeight(500)
-           .width(280)
-           .height(60)
-           //点击Button实现页面跳转
-           .onClick(() => {        router.push({ uri: 'pages/details' })      })
-       }
-       //容器整体宽高
-       .width('100%')
-       .height('100%')
-     }
-   }
-   ```
-2. 再次使用[预览器](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/previewer-0000001054328973#ZH-CN_TOPIC_0000001056725592__section16523172216252)运行项目，效果如下图所示：

+## 场景介绍
+当应用申请的权限需要用户授权，即申请的权限为user_grant权限时，可以通过权限校验，判断当前调用者是否具备相应权限。
+## 接口说明
+接口的具体说明可以查阅[API参考](../reference/apis/js-apis-abilityAccessCtrl.md)
+| 接口名                                                       | 描述             |

+| verifyAccessToken(tokenID: number, permissionName: string): Promise&lt;GrantStatus&gt; | 校验应用是否授予权限，使用Promise方式异步返回结果。 |
+## 开发步骤
+对访问者进行权限校验的开发步骤为：
+1. 获取调用者的身份标识: tokenId
+2. 识别需要校验的权限: permissionNameUser
+3. 对当前调用者进行权限校验
+代码示例如下：
+```js
+  import {describe, beforeEach, afterEach, it, expect} from 'deccjsunit/index'
+  import abilityAccessCtrl from '@ohos.abilityAccessCtrl'
+  import bundle from '@ohos.bundle'
+  var permissionNameUser = "ohos.permission.ALPHA";
+  var bundleFlag = 0;
+  var tokenID = undefined;
+  var userID = 100;
+  var appInfo = await bundle.getApplicationInfo('ohos.acts.security.access_token.normal', bundleFlag, userID);
+  tokenID = appInfo.accessTokenId;
+  console.log("AccessTokenTest accessTokenId:" + appInfo.accessTokenId + ", name:" + appInfo.name
+      + ", bundleName:" + appInfo.bundleName)
+  var atManager = abilityAccessCtrl.createAtManager();
+  var result = await atManager.verifyAccessToken(tokenID, permissionNameUser);
+  if (result == abilityAccessCtrl.GrantStatus.PERMISSION_GRANTED) {
+      // 执行操作
+  } else {
+      // 申请动态授权，使用接口：requestPermissionsFromUser
+  }
+```
+> **说明：**

+# 访问控制开发指南
+## 功能简介
+ATM(AccessTokenManager)是OpenHarmony上基于AccessToken构建的统一的应用权限管理能力。
+当前，ATM模块对应用提供了权限校验功能，应用可以检查当前访问者是否具有所需的权限。
+## 基本概念
+当前，ATM提供的应用权限校验功能是基于统一管理的TokenID(Token identity)。
+- TokenID：32bits的设备内唯一标识符，用于标识每个应用的Accestoken信息。
+- Accestoken信息：主要包括应用身份标识APPID、用户ID、应用分身索引、应用APL(Ability Privilege Level)、应用权限信息等。
+## 约束与限制
+ - 应用不允许自定义权限，系统权限定义信息详见[权限定义信息](https://gitee.com/openharmony/resources/blob/master/systemres/main/config.json)
