+As described in [Permission Workflows](permission-workflows), you need to first apply for the required permissions for the app.
+
+- Applying for permissions
+
+   You need to [declare the required permissions](accesstoken-guidelines.md#declaring-permissions) in the configuration file.
 
-- For a system_grant permission, you need to [declare the permission](accesstoken-guidelines.md#declaring-permissions) in the configuration file. The permission will be pre-granted when the app is installed.
+- Authorizing permissions
 
-- For a user_grant permission, you need to [declare the permission](accesstoken-guidelines.md#declaring-permissions) in the configuration file and trigger user authorization through a dialog box during the running of the app.

-### Permission Authorization Process (user_grant)

 1. In the configuration file, declare the permissions required by the app. For details, see [Access Control Development](accesstoken-guidelines.md).
 
-2. Associate the object that requires the permissions in the app with the target permissions. In this way, the user knows the operations to be granted with the specified permissions.
+2. Associate the target objects in the app with the related permissions. This allows the users to know the operations that need user authorization.
 
-3. Check whether the user has granted the required permissions to the app when the app is running. If yes, the app can access the data or perform the operation. If the user has not granted the permissions to the app, display a dialog box requesting the user authorization when the app attempts to access the data.
+3. Use an API to dynamically trigger a dialog box requesting user authorization when the target object is accessed. The API first checks whether the user has granted the required permissions to the app. If yes, the app can access the data or perform the operation. Otherwise, a dialog box will be displayed to request user authorization.
 
-4. Check the user authorization result. Allow the next step only after the user has granted the permissions to the app.
+4. Check the user authorization result. Allow the subsequent operation only after the user has granted the permissions to the app.
 
 **Precautions**
 
 - Check the app's permission each time before the operation requiring the permission is performed.
-- To check whether a user has granted specific permissions to your app, use the [verifyAccessToken](../reference/apis/js-apis-abilityAccessCtrl.md) method. This method returns [PERMISSION_GRANTED](../reference/apis/js-apis-abilityAccessCtrl.md) or [PERMISSION_DENIED](../reference/apis/js-apis-abilityAccessCtrl.md). For details about the sample code, see [Access Control Development](accesstoken-guidelines.md).
-- Users must be able to understand and control the authorization of user_grant permissions. During the running process, the app requiring user authorization must proactively call the API to dynamically request the authorization. Then, the system displays a dialog box asking the user to grant the requested permission. The user will determine whether to grant the permission based on the running context of the app.
+- To check whether a user has granted specific permissions to an app, use the [verifyAccessToken](../reference/apis/js-apis-abilityAccessCtrl.md) method.

 - The permission authorized is not permanent, because the user may revoke the authorization at any time. Therefore, even if the user has granted the requested permission to the app, the app must check for the permission before calling the API controlled by this permission.
 
 ## ACL
 
 As described above, permission levels and app APLs are in one-to-one correspondence. In principle, **an app with a lower APL cannot apply for higher permissions by default**.

+# Permission Verification Guide
+
+## When to Use
+
+To protect sensitive data and eliminate security threads on core abilities, you can use the permissions in the [App Permission List](permission-list.md) to protect the related API from unauthorized calling. Each time before the API is called, a permission verification is performed to check whether the caller has the required permission.
+
+## Available APIs
+
+The table below lists only the API used in this guide. For more information, see [AbilityContext](../reference/apis/js-apis-ability-context.md).
+
+| API                                                      | Description                                            |
+| ------------------------------------------------------------ | --------------------------------------------------- |
+| verifyAccessToken(tokenID: number, permissionName: string): Promise<GrantStatus> | Checks whether an application process has the specified permission.|
+
+
+## Example
+
+The procedure is as follows:
+
+1. Obtain the caller's identity (**tokenId**).
+2. Determine the permission to verify, which is **ohos.permission.PERMISSION** in this example.
+3. Call **verifyAccessToken()** to perform a permission verification of the caller.
+4. Proceed based on the permission verification result.
+
+```js
+  import abilityAccessCtrl from '@ohos.abilityAccessCtrl'
+  import rpc from '@ohos.rpc'
+
+  class Stub extends rpc.RemoteObject {
+      onRemoteRequest(code, data, reply, option) {
+          let callerTokenId = rpc.IPCSkeleton.getCallingTokenId();
+          console.log("RpcServer: getCallingTokenId result: " + callerTokenId);
+          var atManager = abilityAccessCtrl.createAtManager();
+          var result = await atManager.verifyAccessToken(tokenID, "ohos.permission.PERMISSION");
+          if (result == abilityAccessCtrl.GrantStatus.PERMISSION_GRANTED) {
+            // Allow the caller to invoke the API provided by the app.
+          } else {
+            // Deny the caller's access to the API.
+          }
+          return true;
+      }
+  }
+
+```
+> **NOTE**<br>
+> You can use **getCallingTokenId** to obtain the caller's **tokenId**. For details, see [RPC](../reference/apis/js-apis-rpc.md#getcallingtokenid8).

+## Stage模型是否推荐用globalThis去获取Context
+
+适用于：OpenHarmony SDK 3.2.5.5版本，API9 Stage模型
+
+不推荐，Stage模型使用globalThis去获取Context是错误的使用方式。在Stage模型中，整个应用进程共用一个js虚拟机实例，其中可以运行多个Ability实例，共用一个global对象。在同一个js虚拟机内的不同的Ability中使用globalThis获取Context，存在被覆盖从而发生错误的风险。
+
+推荐使用方式参考：[Stage模型和Context详细介绍](../ability/context-userguide.md#stage%E6%A8%A1%E5%9E%8B%E5%92%8Ccontext%E8%AF%A6%E7%BB%86%E4%BB%8B%E7%BB%8D)。
+
+## 如何在应用A中去获取应用B的Hap包的安装路径
+
+适用于：OpenHarmony SDK 3..0以上版本， API9 Stage模型
+
+首先需要申请系统权限，具体参看文档：[自动化签名](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/ohos-auto-configuring-signature-information-0000001271659465)。导入bundle模块，通过调用bundle.getApplicationInfo()接口，通过包名获取应用信息。然后通过application.moduleSourceDirs获取应用存储路径。
+
+## 调用方使用startAbilityForResult，被调用方如何返回数据
+
+适用于：OpenHarmony SDK3.0, API9 Stage模型
+
+被调用方使用AbilityContext.terminateSelfWithResult方法，销毁被调用方ability，传递参数给startAbilityForResult回调函数，具体用法请参考[AbilityContext](../reference/apis/js-apis-ability-context.md#abilitycontextterminateselfwithresult)
+
+## FA卡片上架后在用户的服务中心展示时可否触发生命周期，从而实现用户没有打开过FA应用的情况下获取到用户的登录信息？

+
+服务卡片在添加卡片后就触发了oncreat()生命周期，在不启用app的情况下也可以显示相关的用户信息-静默登录，但服务卡片目前要在app安装之后手动添加。
+
+## 如何获取context
+
+适用于：OpenHarmony SDK 3.2.7.5版本, API9 Stage模型
+
+在MainAbility.ts文件中可以直接使用this.context获取context，在组件页面中可以使用getContext(this)获取context。
+
+## 访问控制管理模块abilityAccessCtrl中grantUserGrantedPermission方法在API8语法校验提示未定义
+
+适用于：OpenHarmony SDK 3.0版本, API8 FA模型
+
+当前SDK有fullSDK和publicSDK两个版本，IDE默认下载的是publicSDK。其中，publicSDK版本不会包含系统API，如果要用系统API，需要使用fullSDK。具体参考[full-SDK替换指南](../quick-start/full-sdk-switch-guide.md)。
+
+## public sdk支持哪几种ExtensionAbility（ServiceExtensionAbility、FormExtensionAbility、DataShareExtensionAbility）
+
+适用于：OpenHarmony SDK 3.2.5.6版本， API9 Stage模型
+
+上述ExtensionAbility 中，public sdk 仅可以使用FormExtensionAbility。ServiceExtensionAbility和DataShareExtensionAbility 为系统接口，需要使用full sdk。
+
+Public SDK : 面向应用开发者提供，不包含需要使用系统权限的系统接口。
+
+Full SDK : 面向OEM厂商提供，包含了需要使用系统权限的系统接口。

+## 如何实现如果文件不存在则创建文件
+
+适用于：OpenHarmony SDK 3.2.6.3版本，API9 Stage模型
+
+可以通过调用函数fileio.open(filePath, 0o100, 0o666)来实现，第二个参数0o100表示若文件不存在，则创建文件。使用该选项时必须指定第三个参数 mode。

+fileio中接口入参为path时只能是从context获取到的本应用沙箱路径，若要访问其他路径的数据，如公共数据图片视频等，需要通过数据所有者打开文件返回fd进行操作。
+
+比如向mediaLibrary请求读取/写入某文件，然后通过打开代表特定文件的URI后返回的fd进行操作，操作步骤如下：
+
+1. 通过媒体查询获取文件fileAsset对象；
+
+2. 通过fileAsset.open方法返回的fd；
+
+3. 将fd作为fileIo接口参数进行文件读写操作；
+
+## 如何解决文件的中文内容乱码

+TS语言的使用在生成器函数中存在以下限制：
+
+- 表达式仅允许在字符串(${expression})、if条件、ForEach的参数和组件的参数中使用；
+
+- 这些表达式中的任何一个都不能导致任何应用程序状态变量（\@State、\@Link、\@Prop）的改变，否则会导致未定义和潜在不稳定的框架行为；
+
+- 生成器函数内部不能有局部变量。
+
+上述限制都不适用于事件处理函数（例如onClick）的匿名函数实现。
+
+错误示例：
+
+  
+```
+build() {
+  let a: number = 1 // invalid: variable declaration not allowed
+  Column() {
+    Text('Hello ${this.myName.toUpperCase()}') // ok.

+  }
+});
+```
+
+## 如何将Resource资源对象转成string类型
+
+适用于：OpenHarmony SDK 3.2.3.5版本，API9 Stage模型
+
+通过\@ohos.resourceManager模块 resourceManager.getString()方法获取字符串。
+
+参考文档：[资源管理](../reference/apis/js-apis-resource-manager.md#getstring)
+
+## class全局静态变量无法使用的问题
+
+适用于：OpenHarmony SDK 3.2.3.5版本，API9 Stage模型
+
+Page和Ability打包后会对import的对象分别形成两个不同的闭包，即打包出两个Global对象。因此，所引用的静态变量并不是同一对象，所以无法通过class静态变量方式定义全局变量。建议使用AppStorage进行全局变量管理。
+
+参考文档：[应用程序的数据存储](../ui/ts-application-states-appstorage.md)
+
+## Stage模型下如何获取资源
+
+适用于：OpenHarmony SDK 3.2.3.5版本，API9 Stage模型
+
+Stage模型支持了通过context获取resourceManager对象的方式，再调用其内部获取资源的接口，无需再导入包，此方式FA模型不适用。
+
+示例：
+
+  
+```
+const context = getContext(this) as any
+context 
+  .resourceManager
+  .getString($r('app.string.entry_desc').id)
+  .then(value => {
+    this.message = value.toString()
+})
+```
+
+## 如何实现页面加载前从接口获取数据 
+
+适用于：OpenHarmony SDK 3.2.5.5版本，API9 Stage模型
+
+aboutToAppear函数中使用异步接口获取页面数据，使用\@State修饰变量，数据获取完成后根据变量自动刷新页面。
+
+  
+```
+@Entry
+@Component
+struct Test6Page {
+  // 数据获取成功，会自动刷新页面
+  @State message: string = 'loading.....'
+  aboutToAppear(){
+    // 模拟异步接口获取数据
+    setTimeout(()=>{
+      this.message = 'new msg'
+    },3000)
+  }
+  build() {
+    Row() {

+## 如何设置前置拍照
+
+适用于：OpenHarmony SDK 3.2.3.5版本，API9 Stage模型
+
+1. 设置相机位置camera.CameraPosition.CAMERA_POSITION_FRONT
+
+2. 根据相机位置和类型创建CameraInput实例
+
+参考文档：[相机管理](../reference/apis/js-apis-camera.md#%E7%9B%B8%E6%9C%BA%E7%AE%A1%E7%90%86)
+
+示例：
+
+```
+//默认设置后置相机,通过设置isFrontCamera来切换相机
+let cameraId
+let cameraInput
+for(let cameraIndex = 0; cameraIndex < this.cameraArray.length; cameraIndex++) {
+   let faceType = this.cameraArray[cameraIndex].cameraPosition
+   switch(faceType) {
+  case camera.CameraPosition.CAMERA_POSITION_FRONT://前置相机
+    if(this.isFrontCamera){
+   cameraId = this.cameraArray[cameraIndex].cameraId
+    }
+	   break
+	 case camera.CameraPosition.CAMERA_POSITION_BACK://后置相机
+	   if(!this.isFrontCamera){
+		 cameraId = this.cameraArray[cameraIndex].cameraId
+	   }
+	   break
+	 case camera.CameraPosition.CAMERA_POSITION_UNSPECIFIED:
+	 default:
+	   break
+   }
+}
+cameraInput = await this.cameraManager.createCameraInput(cameraId)熊文帅
+```
+
+## 如何进行图片剪切
+
+适用于：OpenHarmony 3.2.5.6版本，API9 Stage模型
+
+1. **通过传入的uri创建图片源实例ImageSource对象。**
+     
+   ```
+   let path = this.context.getApplicationContext().fileDirs + "test.jpg";
+   const imageSourceApi = image.createImageSource(path);
+   ```
+
+2. **设置解码参数，通过图片解码获取PixelMap图像对象，解码过程中同时支持图像处理操作。**
+   - 设置desiredSize支持按尺寸缩放，如果设置为全0，则不进行缩放。
+   - 设置desiredRegion支持按矩形区域裁剪，如果设置为全0，则不进行裁剪。
+   - 设置rotateDegrees支持旋转角度，以图像中心点顺时针旋转。
+        
+      ```
+      const decodingOptions = {
+        desiredSize: {
+        height:0,
+        width:0
+        },
+        //按矩形区域裁剪
+        desiredRegion: {
+        size: {
+         height:100,
+         width:100
+        },
+        x:0,
+        y:0
+        },
+        //旋转90度
+        rotate:90
+      }
+      imageSourceApi.createPixelMap(decodingOptions).then(pixelMap => {
+        this.handlePixelMap(pixelMap)
+      })
+      ```
+
+3. 解码完成获取到PixelMap对象后，可以进行后续处理，比如渲染显示等。
+
+## 如何申请设备上的媒体读写权限
+
+适用于：OpenHarmonySDK 3.2.5.5版本，API9 Stage模型
+
+1. 在module.json5配置文件中配置媒体读写权限ohos.permission.READ_MEDIA和ohos.permission.WRITE_MEDIA。
+   示例：
+
+     
+   ```
+   {
+     "module" : {
+       "requestPermissions":[
+         {
+           "name" : "ohos.permission.READ_MEDIA",
+           "reason": "$string:reason"
+         },
+         {
+           "name" : "ohos.permission.WRITE_MEDIA",
+           "reason": "$string:reason"
+         }
+       ]
+     }
+   }
+   ```
+
+2. 这两个权限的授权方式均为user_grant，因此需要调用requestPermissionsFromUser接口，以动态弹窗的方式向用户申请授权。
+     
+   ```
+   let permissions: Array<string> = ['ohos.permission.READ_MEDIA','ohos.permission.WRITE_MEDIA']
+   context.requestPermissionsFromUser(permissions).then((data) => {
+       console.log("Succeed to request permission from user with data: " + JSON.stringify(data))
+   }).catch((error) => {
+       console.log("Failed to request permission from user with error: " + JSON.stringify(error))
+   })
+   ```
+
+## MP4格式的视频为什么播放不了

+
+## Web组件加载h5页面，首次加载无法设置拼接UserAgent参数
+
+适用于：OpenHarmony SDK 3.2.6.5版本，API9 Stage模型
+
+默认UserAgent通过WebController获取。一个WebController对象只能控制一个Web组件，且必须在Web组件和WebController绑定后，才能调用WebController上的方法，因此在初次加载前设置默认UserAgent + 自定义字符串拼接，可采用此方式：
+
+1. 使用\@State定义初始userAgent，绑定到Web组件；
+
+2. 在web组件的onUrlLoadIntercept回调中，通过WebController获取默认userAgent，修改Web组件绑定的userAgent。
+   参考代码如下：
+
+     
+   ```
+   @Entry
+   @Component
+   struct Index {
+     private controller: WebController = new WebController()
+     @State userAgentPa: string = ''
