 # 跨端迁移

 ## 功能描述
 
 跨端迁移的主要工作是实现将应用当前任务（包括页面控件状态变量等）迁移到目标设备，能在目标设备上接续。主要功能包括：
 
 - 支持用户自定义数据存储及恢复。
-
 - 支持页面路由信息和页面控件状态数据的存储及恢复。
-
 - 支持应用兼容性检测。
-
-- 支持应用根据实际使用场景动态设置迁移状态（默认迁移状态为ACTIVE激活状态）。如编辑类应用在编辑文本的页面下才需要迁移，其他页面不需要迁移，则可以通过[setMissionContinueState](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextsetmissioncontinuestate10)进行控制。

+
+- 保存迁移数据：开发者可以将要迁移的数据通过键值对的方式保存在wantParam中。
+
+- 应用兼容性检测：开发者可以通过从wantParam中获取目标应用的版本号与本应用版本号做兼容性校验。开发者可以在触发迁移时从`onContinue`接口中`wantParam.version`获取到迁移目标端应用的版本号与迁移发起端应用版本号做兼容校验。
+
+- 迁移决策：开发者可以通过onContinue接口的返回值决定是否支持此次迁移，返回值信息见[接口说明](#接口说明)。
+
+  示例如下：
+
+  ```ts
+  import UIAbility from '@ohos.app.ability.UIAbility';
+  import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+
+  export default class EntryAbility extends UIAbility {
+    onContinue(wantParam: Record<string, Object>) {
+      console.info(`onContinue version = ${wantParam.version}, targetDevice: ${wantParam.targetDevice}`) // 准备迁移数据
+      let continueInput = '迁移的数据';

+
+5.在Stage模型中，应用在不同启动模式下将调用不同的接口，以恢复数据、加载界面。

+
+在目标端设备UIAbility中实现onCreate与onNewWant接口，恢复迁移数据。

+- onCreate实现示例
+   - 目标端设备上，在onCreate中根据launchReason判断该次启动是否为迁移LaunchReason.CONTINUATION。
+   - 开发者可以从want中获取保存的迁移数据。
+   - 完成数据恢复后，开发者需要调用restoreWindowStage来触发页面恢复：包括页面栈信息。
+     
+      ```ts
+      import UIAbility from '@ohos.app.ability.UIAbility';
+      import AbilityConstant from '@ohos.app.ability.AbilityConstant';

+        onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
+          console.info(`EntryAbility onCreate ${AbilityConstant.LaunchReason.CONTINUATION}`)
+          if (launchParam.launchReason == AbilityConstant.LaunchReason.CONTINUATION) {
+            // 将上述的保存的数据取出恢复
+            let continueInput = '';
+            if (want.parameters != undefined) {
+              continueInput = JSON.stringify(want.parameters.data);
+              console.info(`continue input ${continueInput}`)
+            }
+            // 将数据显示当前页面
+            this.context.restoreWindowStage(this.storage);
+          }
+        }
+      }
+      ```
+- 如果是单实例应用，需要额外实现onNewWant接口，实现方式与onCreate的实现相同。
+   - 在onNewWant中判断迁移场景，恢复数据，并触发页面恢复
+

+## 迁移功能可选配置
+
+### 1.动态配置迁移能力
+
+从API 10 起，提供了支持动态配置迁移能力的功能。即应用可以根据实际使用场景，在需要迁移功能时，设置开启应用迁移能力；在业务不需要迁移时，则可以关闭迁移能力。开发者可以通过调用[setMissionContinueState](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextsetmissioncontinuestate10)接口对迁移能力进行设置。默认状态下，可迁移应用的迁移能力为**ACTIVE**状态，即迁移能力开启，可以迁移。
+
+| 接口状态值                             | 含义                   |
+| :------------------------------------- | ---------------------- |
+| AbilityConstant.ContinueState.ACTIVE   | 应用当前可迁移能力开启 |
+| AbilityConstant.ContinueState.INACTIVE | 应用当前可迁移能力关闭 |
+
+**设置迁移能力的时机**
+
+迁移能力的改变可以根据实际业务需求和代码实现，发生在应用生命周期的绝大多数时机。本文介绍常用的几种配置方式。
+
+在ability的onCreate函数中调用接口，可以在应用创建时设置应用的迁移状态。
+
+```ts
+// EntryAbility.ets
+import UIAbility from '@ohos.app.ability.UIAbility';
+import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+import Want from '@ohos.app.ability.Want';
+export default class EntryAbility extends UIAbility {
+  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
+    // ...
+    this.context.setMissionContinueState(AbilityConstant.ContinueState.INACTIVE, (result) => {
+      console.info(`setMissionContinueState: ${JSON.stringify(result)}`);
+    });
+    // ...
+  }
+}
+```
+
+在页面的onPageShow函数中调用接口，可以设置单个页面出现时应用的迁移状态。
+
+```ts
+// PageName.ets
+import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+import common from '@ohos.app.ability.common'
+@Entry
+@Component
+struct PageName {
+  private context = getContext(this) as common.UIAbilityContext;
+  build() {
+    // ...
+  }
+  // ...
+  onPageShow(){
+  // 进入该页面时，将应用设置为可迁移状态
+    this.context.setMissionContinueState(AbilityConstant.ContinueState.ACTIVE, (result) => {
+      console.info('setMissionContinueState ACTIVE result: ', JSON.stringify(result));
+    });
+  }
+}
+```
+
+在某个组件的触发事件中设置应用迁移能力。如下例中，使用 **Button** 组件的 **onClick** 事件，触发迁移能力的改变。
+
+```ts
+// PageName.ets
+import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+import common from '@ohos.app.ability.common'
+@Entry
+@Component
+struct PageName {
+  private context = getContext(this) as common.UIAbilityContext;
+  build() {
+    // ...
+    Button() {
+      //...
+    }.onClick(()=>{
+    //点击该按钮时，将应用设置为可迁移状态
+      this.context.setMissionContinueState(AbilityConstant.ContinueState.ACTIVE, (result) => {
+        console.info('setMissionContinueState ACTIVE result: ', JSON.stringify(result));
+      });
+    })
+  }
+}
+```
+
+**保证迁移连续性**
+
+由于迁移加载时，目标端拉起的应用可能执行过自己的迁移状态设置命令（如：冷启动时目标端在onCreate中设置了 **INACTIVE** ；热启动时对端已打开了不可迁移的页面，迁移状态为 **INACTIVE** 等情况）。为了保证迁移过后的应用依然具有可以迁移回发起端的能力，应在 onCreate和onNewWant的迁移调用判断中，将迁移状态设置为 **ACTIVE** 。
+
+```ts
+// EntryAbility.ets
+import UIAbility from '@ohos.app.ability.UIAbility';
+import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+import Want from '@ohos.app.ability.Want';
+export default class EntryAbility extends UIAbility {
+  // ...
+  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
+    // ...
+    // 调用原因为迁移时，设置状态为可迁移，应对冷启动情况
+    this.context.setMissionContinueState(AbilityConstant.ContinueState.INACTIVE, (result) => {
+      console.info(`setMissionContinueState: ${JSON.stringify(result)}`);
+    });
+  }
+  onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam): void {
+    // ...
+    // 调用原因为迁移时，设置状态为可迁移，应对热启动情况
+    if (launchParam.launchReason == AbilityConstant.LaunchReason.CONTINUATION) {
+      this.context.setMissionContinueState(AbilityConstant.ContinueState.ACTIVE, (result) => {
+        console.info('setMissionContinueState ACTIVE result: ', JSON.stringify(result));
+      });
+    }
+  }
+  // ...
+}
+```
+
+
+
+### 2.按需迁移页面栈
+
+支持应用动态选择是否进行页面栈恢复（默认进行页面栈信息恢复）。如果应用不想使用系统默认恢复的页面栈，则可以设置不进行页面栈迁移，而需要在`onWindowStageRestore`设置迁移后进入的页面，参数定义见[SUPPORT_CONTINUE_PAGE_STACK_KEY](../reference/apis/js-apis-app-ability-wantConstant.md#wantconstantparams)。
+
+应用在发起端的页面栈中存在Index和Second路由，而在目标端恢复时不需要按照发起端页面栈进行恢复，需要恢复到指定页面。
+
+- 示例：应用迁移不需要自动迁移页面栈信息
+
+    ```ts
+    // EntryAbility.ets
+    import UIAbility from '@ohos.app.ability.UIAbility';
+    import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+    import wantConstant from '@ohos.app.ability.wantConstant';
+    import window from '@ohos.window';
+    export default class EntryAbility extends UIAbility {
+      // ...
+      onContinue(wantParam: Record<string, Object>) {
+        console.info(`onContinue version = ${wantParam.version}, targetDevice: ${wantParam.targetDevice}`);
+        wantParam[wantConstant.Params.SUPPORT_CONTINUE_PAGE_STACK_KEY] = false;
+        return AbilityConstant.OnContinueResult.AGREE;
+      }
+      // ...
+      onWindowStageRestore(windowStage: window.WindowStage) {
+          // 若不需要自动迁移页面栈信息，则需要在此处设置应用迁移后进入的页面
+        windowStage.loadContent('pages/Index', (err, data) => {
+          if (err.code) {
+            console.info('Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');
+            return;
+          }
+          console.info('Succeeded in loading the content. Data: %{public}s', JSON.stringify(data) ?? '');
+        });
+      }
+    }
+    ```
 
-   - 应用兼容性检测：开发者可以通过从wantParam中获取目标应用的版本号与本应用版本号做兼容性校验。开发者可以在触发迁移时从`onContinue`接口中`wantParam.version`获取到迁移接收端应用的版本号与迁移发起端应用版本号做兼容校验。
+### 3.按需退出
 
-   - 迁移决策：开发者可以通过onContinue接口的返回值决定是否支持此次迁移，返回值信息见[接口说明](#接口说明)。
+支持应用动态选择迁移成功后是否退出迁移发起端应用（默认迁移成功后退出迁移发起端应用）。如果应用不想让系统自动退出迁移发起端应用，则可以设置不退出，参数定义见[SUPPORT_CONTINUE_SOURCE_EXIT_KEY](../reference/apis/js-apis-app-ability-wantConstant.md#wantconstantparams)。
 
-     示例如下：
+- 示例：应用迁移设置不需要迁移成功后退出迁移发起端应用
 
-   ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility';
-   import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+    ```ts
+    import UIAbility from '@ohos.app.ability.UIAbility';
+    import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+    import wantConstant from '@ohos.app.ability.wantConstant';
+    export default class EntryAbility extends UIAbility {
+      // ...
+      onContinue(wantParam: Record<string, Object>) {
+        console.info(`onContinue version = ${wantParam.version}, targetDevice: ${wantParam.targetDevice}`);
+        wantParam[wantConstant.Params.SUPPORT_CONTINUE_SOURCE_EXIT_KEY] = false;
+        return AbilityConstant.OnContinueResult.AGREE;
+      }
+      // ...
+    }
+    ```
 
-   onContinue(wantParam : {[key: string]: any}) {
-       console.info(`onContinue version = ${wantParam.version}, targetDevice: ${wantParam.targetDevice}`)
-       let workInput = AppStorage.Get<string>('ContinueWork');
-       // set user input data into want params
-       wantParam["work"] = workInput // set user input data into want params
-       console.info(`onContinue input = ${wantParam["input"]}`);
-       return AbilityConstant.OnContinueResult.AGREE
-   }
-   ```
+## 验证指导
 
-5. 在目标端设备UIAbility中实现onCreate()与onNewWant()接口，恢复迁移数据。
-   - onCreate实现示例
-      - 目标端设备上，在onCreate中根据launchReason判断该次启动是否为迁移LaunchReason.CONTINUATION。
-      - 开发者可以从want中获取保存的迁移数据。
-      - 完成数据恢复后，开发者需要调用restoreWindowStage来触发页面恢复：包括页面栈信息。
-
-         ```ts
-         import UIAbility from '@ohos.app.ability.UIAbility';
-         import AbilityConstant from '@ohos.app.ability.AbilityConstant';
-         import distributedObject from '@ohos.data.distributedDataObject';
-
-         export default class EntryAbility extends UIAbility {
-             storage : LocalStorage;
-             onCreate(want, launchParam) {
-                 console.info(`EntryAbility onCreate ${AbilityConstant.LaunchReason.CONTINUATION}`)
-                 if (launchParam.launchReason == AbilityConstant.LaunchReason.CONTINUATION) {
-                     // get user data from want params
-                     let workInput = want.parameters.work
-                     console.info(`work input ${workInput}`)
-                     AppStorage.SetOrCreate<string>('ContinueWork', workInput)
-                     this.storage = new LocalStorage();
-                     this.context.restoreWindowStage(this.storage);
-                 }
-             }
-         }
-         ```
-   - 如果是单实例应用，需要额外实现onNewWant()接口，实现方式与onCreate()的实现相同。
-      - 在onNewWant()中判断迁移场景，恢复数据，并触发页面恢复
-
-         ```ts
-         export default class EntryAbility extends UIAbility {
-             storage : LocalStorage;
-             onNewWant(want, launchParam) {
-                 console.info(`EntryAbility onNewWant ${AbilityConstant.LaunchReason.CONTINUATION}`)
-                 if (launchParam.launchReason == AbilityConstant.LaunchReason.CONTINUATION) {
-                     // get user data from want params
-                     let workInput = want.parameters.work
-                     console.info(`work input ${workInput}`)
-                     AppStorage.SetOrCreate<string>('ContinueWork', workInput)
-                     this.storage = new LocalStorage();
-                     this.context.restoreWindowStage(this.storage);
-                 }
-             }
-         }
+为方便开发者验证已开发的可迁移应用，当前OpenHarmony提供了一个全局任务中心demo作为迁移的入口。下面介绍通过安装全局任务中心来验证迁移的方式。
 
-6. **可选配置：** 在应用支持迁移特性时，默认开启应用迁移状态开关，根据应用当前任务获取焦点/失去焦点通知周边的可信设备当前任务可流转/取消流转。若应用需要在特定场景下才通知周边设备可流转，则需要在应用打开时设置迁移状态为INACTIVE，在后续的业务流程中需要迁移时再设置迁移状态为ACTIVE。接口见[setMissionContinueState](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextsetmissioncontinuestate10)。
+### 1. 编译安装全局任务中心
 
-    - 示例：应用启动不需要流转
+#### **配置环境**
 
-        ```ts
-        import UIAbility from '@ohos.app.ability.UIAbility';
-        import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+public-SDK不支持开发者使用所有的系统API，例如：全局任务中心使用的[**@ohos.distributedDeviceManager**](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/reference/apis/js-apis-distributedDeviceManager.md)不包括在public_SDK中。因此为了正确编译安装全局任务中心，开发者需要替换full-SDK，具体操作可参见[替换指南](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/faqs/full-sdk-switch-guide.md)。
