+# IPC通信示例
+
+## 介绍
+
+本示例展示了如何使用[@ohos.rpc](https://gitcode.com/openharmony/docs/blob/master/zh-cn/application-dev/reference/apis-ipc-kit/js-apis-rpc.md) 相关接口，开发一个IPC客户端与服务端通信的完整示例。在此示例中仅演示如何传递字符串信息，若有除此之外接口的诉求，请自行参考接口文档中的示例代码。
+
+## 效果预览
+
+|客户端|服务端|
+|-------------------------|----------------------|
+|![](image/IPC_Client.png)|![](image/IPC_Stub.png)|
+
+使用说明：
+
+1. 点击 connectAbility 按钮进行连接服务端，获取到服务端的代理对象proxy，并在此时注册死亡监听，当服务端所在进程死亡时，会触发此监听，提示服务端已死亡，并断开连接服务端；
+2. 点击 sendRequest_string 按钮传递字符串信息至服务端，服务端会收到这次传递的字符串（'hello world'）,并返回字符串（'hello rpc'）到客户端，代表此次通信结束；
+3. 点击 disconnectAbility 按钮断开连接服务端。
+
+## 工程目录
+
+1. 客户端-IPC_Client

+|   |---ServiceExtAbility.ets   // 服务端实现    
+```
+
+以上工程目录中未进行说明的部分，是默认工程目录结构，并未进行修改。
+
+## 具体实现
+
+1. 创建ServiceExtensionAbility，实现服务端
+
+  ```ets
+    // 定义服务端
+    class Stub extends rpc.RemoteObject {
+      constructor(descriptor: string) {
+        super(descriptor);
+      }
+      onRemoteMessageRequest(code: number, data: rpc.MessageSequence, reply: rpc.MessageSequence, option: rpc.MessageOption): boolean | Promise<boolean> {
+        // 服务端Stub根据不同的请求code分别执行对应的处理流程
+        if (code == 1) {
+          let str = data.readString();
+          hilog.info(0x0000, 'testTag', 'IPCStub: stub receive str : ' + str);
+          // 服务端使用reply回传请求处理的结果给客户端
+          reply.writeString('hello rpc');
+          return true;
+        } else {
+          hilog.info(0x0000, 'testTag', 'IPCStub: stub unknown code: ' + code);
+          return false;
+        }
+      }
+    }
+
+    // 定义后台服务
+    export default class ServiceAbility extends ServiceExtensionAbility {
+      // ......
+
+       onConnect(want: Want): rpc.RemoteObject {
+         hilog.info(0x0000, 'testTag', 'IPCStub: onConnect');
+         // 返回Stub对象，客户端获取后便可以与ServiceExtensionAbility进行通信
+         return new Stub('IPCStubTest');
+       }
+
+      // ......
+    }
+  ```
+
+2. 客户端连接服务
+
+  ```ets
+    function connectAbility(context:common.UIAbilityContext) {
+      hilog.info(0x00000, 'testTag', 'IPCClient: begin to connect Ability');
+
+      let connect: common.ConnectOptions = {
+        onConnect: (elementName, remoteProxy) => {
+          hilog.info(0x00000, 'testTag', 'IPCClient: onConnect. elementName is :' + JSON.stringify(elementName));
+          proxy = remoteProxy;
+          // 客户端注册死亡监听
+          try {
+            proxy.registerDeathRecipient(deathRecipient, 0);
+            hilog.info(0x00000, 'testTag', 'IPCClient: registerDeathRecipient success');
+          }catch (err) {
+            let code = (err as BusinessError).code;
+            let message = (err as BusinessError).message;
+            hilog.error(0x0000, 'testTag', 'IPCClient: registerDeathRecipient failed, code is ' + code + ', message is ' + message);
+          }
+        },
+        onDisconnect: (elementName) => {
+          hilog.info(0x0000, 'testTag', 'IPCClient: onDisconnect. elementName is :' + JSON.stringify(elementName));
+          // 客户端移除死亡监听
+          try {
+            proxy?.unregisterDeathRecipient(deathRecipient, 0);
+            hilog.info(0x00000, 'testTag', 'IPCClient: unregisterDeathRecipient success');
+          }catch (err) {
+            let code = (err as BusinessError).code;
+            let message = (err as BusinessError).message;
+            hilog.error(0x0000, 'testTag', 'IPCClient: unregisterDeathRecipient failed, code is ' + code + ', message is ' + message);
+          }
+          proxy = undefined;
+        },
+        onFailed: (code: number) => {
+          hilog.info(0x0000, 'testTag', 'IPCClient: onFailed. code is :' + code);
+        },
+      }
+
+      try {
+        connectId = context.connectServiceExtensionAbility(want, connect);
+      }catch (err) {
+        let code = (err as BusinessError).code;
+        let message = (err as BusinessError).message;
+        hilog.error(0x0000, 'testTag', 'IPCClient: connectAbility failed, code is ' + code + ', message is ' + message);
+      }
+    }
+  ```
+
+3. 客户端发送字符串给服务端
+
+  ```ets
+    function sendString() {
+      hilog.info(0x00000, 'testTag', 'IPCClient: begin to send String');
+      let option = new rpc.MessageOption();
+      let data = rpc.MessageSequence.create();
+      let reply = rpc.MessageSequence.create();
+      // 在data里写入参数，以传递字符串为例
+      data.writeString('hello world');
+      if (proxy != undefined) {
+        proxy.sendMessageRequest(1, data, reply, option)
+          .then((result: rpc.RequestResult) => {
+            if (result.errCode != 0) {
+              hilog.error(0x0000, 'testTag', 'IPCClient: sendMessageRequest failed, errCode: ' + result.errCode);
+              return;
+            }
+            // 从result.reply里读取结果
+            let str = result.reply.readString();
+            hilog.info(0x0000, 'testTag', 'IPCClient: sendMessageRequest receive str: ' + str);
+          })
+          .catch((e: Error) => {
+            hilog.error(0x0000, 'testTag', 'IPCClient: sendMessageRequest failed, error is ' + JSON.stringify(e));
+          })
+          .finally(() => {
+            data.reclaim();
+            reply.reclaim();
+          })
+      }
+    }
+  ```
+
+4. 客户端断开连接服务
+
+  ```ets
+    function disconnectAbility(context: common.UIAbilityContext) {
+      hilog.info(0x00000, 'testTag', 'IPCClient: begin to disconnect Ability');
+      if (connectId != undefined) {
+        try {
+          context.disconnectServiceExtensionAbility(connectId);
+        }catch (err) {
+          let code = (err as BusinessError).code;
+          let message = (err as BusinessError).message;
+          hilog.error(0x0000, 'testTag', 'IPCClient: disconnectAbility failed, code is ' + code + ', message is ' + message);
+        }
+      }
+    }
+  ```
+
+## 相关权限
+
+不涉及
+
+## 依赖
+
+本示例中按键之间存在依赖关系，具体依赖如下：
+
+1. 服务端需保持在后台运行状态下，客户端才可以进行连接服务的操作（'connectAbility'）；
+2. 在连接服务成功的情况下，客户端才可进行发送信息的操作（'sendRequest_string'）；
+3. 在建立连接的情况下，客户端才可进行断连的操作（'disconnectAbility'）。
+
+
+## 约束与限制
+
+1. 本示例仅支持标准系统上运行，支持设备：RK3568。
+
+2. 本示例推荐使用DevEco Studio 5.0.2 Beta1 (Build Version: 5.0.7.100 构建 2025年1月16日)及以上版本编译运行。
+
+3. 本示例需要使用@ohos.app.ability.ServiceExtensionAbility，该模块仅对系统应用开放，业务使用时，需自行替换当前工程中的SDK为FULL SDK。使用Full SDK时需要手动从镜像站点获取，并在DevEcoStudio中替换，具体操作可参考[替换指南](https://gitcode.com/openharmony/docs/blob/master/zh-cn/application-dev/faqs/full-sdk-switch-guide.md) 。
+
+4. 本示例使用了ServiceExtensionAbility，需要在module.json5中进行相应的配置。如下：
+
+在服务端entry下的module.json5中配置如下字段：[module.json5](../IPC_Stub/entry/src/main/module.json5)，参考第48-54行。
+
+  ```
+  "extensionAbilities": [
+    {
+      "name": "ServiceAbility",
+      "srcEntry": "./ets/serviceextability/ServiceExtAbility.ets",
+      "type": "service",
+      "exported": true,
+      "description": "service"
+    }
+  ]
+  ```
+
+## 下载
+
+如需单独下载本工程及服务端，执行如下命令：
+
+  ```
+    git init
+    git config core.sparsecheckout true
+    echo IPC/IPC_sendMessage/ > .git/info/sparse-checkout
+    git remote add origin https://gitcode.com/harmonyos_samples/guide-snippets.git
+    git pull origin master
+  ``` 
+
+## 安装问题（9568344）
+
+因上述应用的module.json5中extensionAbilities字段中type属性为service，普通的安装方法会报错，需要按照以下方式进行安装：
+
+1. 注释module.json5中extensionAbilities字段
+
+![](image/comment.png)
+
+2. 获取app_signature
+
+ ```
+   hdc shell bm dump -n <bundleName> | findstr finger
+ ```
+
+![](image/app_signature.png)
+
+3. 添加白名单
+
+将rk设备的install_list_capability.json配置文件拉取到本地
+
+  ```
+   hdc shell mount -o rw,remount /
+   hdc file recv /system/etc/app/install_list_capability.json   ---rk的方式
+  ```
+
+![](image/recv_install_list_capability.png)
+
+在拉下来的json文件中添加不能安装成功的应用，格式如下：
+
+  ```
+   {
+     "install_list": [
+        {
+          ......
+        },
+        {
+          "bundleName": "应用包名",
+          "app_signature" : ["上面获取的app_signature"],
+          "allowAppUsePrivilegeExtension": true
+        }
+     ]
+   }
+  ```
+
+![](image/configure.png)
+
+4. 将修改后的白名单推送到设备上进行替换并重启
+
+  ```
+    hdc shell mount -o rw,remount /
+    hdc file send install_list_capability.json /system/etc/app/install_list_capability.json  
+    hdc shell chmod 777 /system/etc/app/install_list_capability.json 
+    hdc shell reboot
+  ```
+
+5. 取消module.json5中extensionAbilities的相关注释，重新安装hap包

+# IPC通信示例
+
+## 介绍
+
+本示例展示了如何使用[@ohos.rpc](https://gitcode.com/openharmony/docs/blob/master/zh-cn/application-dev/reference/apis-ipc-kit/js-apis-rpc.md) 相关接口，开发一个IPC客户端与服务端通信的完整示例。在此示例中仅演示如何传递字符串信息，若有传递除此之外接口的诉求，请自行参考接口文档中的示例代码。
+
+## 效果预览
+
+|客户端|服务端|
+|-----------------|----------------------|
+|![](image/RPC_Client.png)|![](image/RPC_Stub.png)|
+|![](image/getPermission.png)| |
+
+
+使用说明：
+
+1. 点击 getPermission 按钮进行获取允许多设备协同的权限；
+2. 点击 getDeviceId 按钮获取对端的设备信息；
+3. 点击 connectAbility 按钮进行连接服务端，获取到服务端的代理对象proxy，并在此时注册死亡监听，当服务端所在进程死亡时，会触发此监听，提示服务端已死亡，并断开连接服务端；
+2. 点击 sendRequest_string 按钮传递字符串信息至服务端，服务端会收到这次传递的字符串（'hello world'）,并返回字符串（'hello rpc'）到客户端，代表此次通信结束；
+3. 点击 disconnectAbility 按钮断开连接服务端。
+
+以上操作建立在双方设备组网的情况下进行。
+

+```
+
+以上工程目录中未进行说明的部分，是默认工程目录结构，并未进行修改。
+
+## 具体实现
+
+1. 创建ServiceExtensionAbility，实现服务端
+
+  ```ets
+    // 定义服务端
+    class Stub extends rpc.RemoteObject {
+      constructor(descriptor: string) {
+        super(descriptor);
+      }
+      onRemoteMessageRequest(code: number, data: rpc.MessageSequence, reply: rpc.MessageSequence, option: rpc.MessageOption): boolean | Promise<boolean> {
+        // 服务端Stub根据不同的请求code分别执行对应的处理流程
+        if (code == 1) {
+          let str = data.readString();
+          hilog.info(0x0000, 'testTag', 'RPC_Stub: stub receive str is ' + str);
+          // 服务端使用reply回传请求处理的结果给客户端
+          reply.writeString('hello rpc');
+          return true;
+        } else {
+          hilog.info(0x0000, 'testTag', 'RPC_Stub: stub unknown code, code is ' + code);
+          return false;
+        }
+      }
+    }
+
+    // 定义后台服务
+    export default class ServiceAbility extends ServiceExtensionAbility {
+      ......
+
+      onConnect(want: Want): rpc.RemoteObject {
+        hilog.info(0x0000, 'testTag', 'RPC_Stub: onConnect');
+        // 返回Stub对象，客户端获取后便可以与ServiceExtensionAbility进行通信
+        return new Stub('RPCStubTest');
+      }
+
+      ......
+    }
+  ```
+
+2. 获取允许多设备协同的权限（客户端服务端需要进行此操作）
+
+  ```ets
+    function getPermission(context:common.UIAbilityContext) {
+      hilog.info(0x00000, 'testTag', 'RpcClient: begin to requestPermissions');
+      try {
+        let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
+        atManager.requestPermissionsFromUser(context, ['ohos.permission.DISTRIBUTED_DATASYNC'], (err: BusinessError, data: PermissionRequestResult) => {
+          if (err) {
+            hilog.error(0x0000, 'testTag', 'RpcClient: registerDeathRecipient failed, code is '  + err.code + ', message is ' + err.message);
+          } else {
+            hilog.info(0x0000, 'testTag','RpcClient: requestPermissionsFromUser success, result is ' + JSON.stringify(data));
+            hilog.info(0x0000, 'testTag','RpcClient: requestPermissionsFromUser data permissions is ' + data.permissions);
+            hilog.info(0x0000, 'testTag','RpcClient: requestPermissionsFromUser data authResults is ' + data.authResults);
+            hilog.info(0x0000, 'testTag','RpcClient: requestPermissionsFromUser data dialogShownResults is ' + data.dialogShownResults);
+          }
+        });
+      }catch (err) {
+        let code = (err as BusinessError).code;
+        let message = (err as BusinessError).message;
+        hilog.error(0x0000, 'testTag', 'RpcClient: getPermission failed, code is  ' + code + ', message is ' + message);
+      }
+    }
+  ```
+
+3. 客户端获取对端设备信息
+
+  ```ets
+    function getDeviceId(){
+      hilog.info(0x00000, 'testTag', 'RpcClient: begin to getDeviceId');
+      try {
+        dmInstance = distributedDeviceManager.createDeviceManager('com.example.rpc_client');
+        hilog.info(0x0000, 'testTag', 'RpcClient: createDeviceManager success');
+        deviceList = dmInstance.getAvailableDeviceListSync();
+        hilog.info(0x0000, 'testTag', 'RpcClient: deviceList is' + JSON.stringify(deviceList));
+        if (deviceList.length !== 0) {
+          deviceId = deviceList[0].networkId;
+          hilog.info(0x0000, 'testTag', 'RpcClient: networkId is ' + deviceId);
+        }
+      }catch (err) {
+        let code = (err as BusinessError).code;
+        let message = (err as BusinessError).message;
+        hilog.error(0x0000, 'testTag', 'RpcClient: getDeviceId failed, code is  ' + code + ', message is ' + message);
+      }
+    }
+  ```
+
+4. 客户端连接服务
+
+  ```ets
+    function connectAbility(context:common.UIAbilityContext) {
+      hilog.info(0x00000, 'testTag', 'RpcClient: begin to connect Ability');
+      let want: Want = {
+        bundleName: 'com.example.rpc_stub',
+        abilityName: 'ServiceAbility',
+        deviceId: deviceId,
+      }
+
+      let connect: common.ConnectOptions = {
+        onConnect: (elementName, remoteProxy) => {
+          hilog.info(0x00000, 'testTag', 'RpcClient: onConnect. elementName is :' +  JSON.stringify(elementName));
+          proxy = remoteProxy;
+          // 客户端注册死亡监听
+          try {
+            proxy.registerDeathRecipient(deathRecipient, 0);
+            hilog.info(0x00000, 'testTag', 'RpcClient: registerDeathRecipient success');
+          }catch (err) {
+            let code = (err as BusinessError).code;
+            let message = (err as BusinessError).message;
+            hilog.error(0x0000, 'testTag', 'RpcClient: registerDeathRecipient failed, code is ' + code + ', message is ' + message);
+          }
+        },
+        onDisconnect: (elementName) => {
+          hilog.info(0x0000, 'testTag', 'RpcClient: onDisconnect. elementName is ' + JSON.stringify(elementName));
+          // 客户端移除死亡监听
+          try {
+            proxy?.unregisterDeathRecipient(deathRecipient, 0);
+            hilog.info(0x00000, 'testTag', 'RpcClient: unregisterDeathRecipient success');
+          }catch (err) {
+            let code = (err as BusinessError).code;
+            let message = (err as BusinessError).message;
+            hilog.error(0x0000, 'testTag', 'RpcClient: unregisterDeathRecipient failed, code is ' + code + ', message is ' + message);
+          }
+          proxy = undefined;
+        },
+        onFailed: (code: number) => {
+          hilog.info(0x0000, 'testTag', 'RpcClient: onFailed. code is :' + code);
+        },
+      }
+
+      try {
+        connectId = context.connectServiceExtensionAbility(want, connect);
+      }catch (err) {
+        let code = (err as BusinessError).code;
+        let message = (err as BusinessError).message;
+        hilog.error(0x0000, 'testTag', 'RpcClient: connectService failed, code is ' + code + ', message is ' + message);
+      }
+    }
+  ```
+
+5. 客户端发送字符串给服务端
+
+  ```ets
+    function sendString() {
+      hilog.info(0x00000, 'testTag', 'RpcClient: begin to send string');
+      let option = new rpc.MessageOption();
+      let data = rpc.MessageSequence.create();
+      let reply = rpc.MessageSequence.create();
+      // 在data里写入参数，以传递字符串为例
+      data.writeString('hello world');
+
+      if (proxy != undefined) {
+        proxy.sendMessageRequest(1, data, reply, option)
+          .then((result: rpc.RequestResult) => {
+            if (result.errCode != 0) {
+              hilog.error(0x0000, 'testTag', 'RpcClient: sendMessageRequest failed, errCode: ' + result.errCode);
+              return;
+            }
+            // 从result.reply里读取结果
+            let str = result.reply.readString();
+            hilog.info(0x0000, 'testTag', 'RpcClient: sendMessageRequest receiver, str: ' + str);
+          })
+          .catch((e: Error) => {
+            hilog.error(0x0000, 'testTag', `RpcClient: sendMessageRequest failed, error is ` + JSON.stringify(e));
+          })
+          .finally(() => {
+            data.reclaim();
+            reply.reclaim();
+          })
+      }
+    }
+  ```
+
+6. 客户端断开连接服务
+
+  ```ets
+    function disconnectAbility(context: common.UIAbilityContext) {
+      hilog.info(0x00000, 'testTag', 'RpcClient: begin to disconnect Ability');
+      if (connectId != undefined) {
+        try {
+          context.disconnectServiceExtensionAbility(connectId);
+        }catch (err) {
+          let code = (err as BusinessError).code;
+          let message = (err as BusinessError).message;
+          hilog.error(0x0000, 'testTag', 'pcClient: disconnectService failed, code is ' + code + ', message is ' + message);
+        }
+      }
+    }
+  ```
+
+## 相关权限
+
+ohos.permission.GET_BUNDLE_INFO
+
+ohos.permission.DISTRIBUTED_DATASYNC
+
+## 依赖
+
+本示例中按键之间存在依赖关系，具体依赖如下：
+
+1. 客户端和服务端需先进行获取权限的操作（'getPermission'）;
+2. 客户端获取权限后需先进行获取设备ID的操作（'getDeviceId'）；
+3. 在获取对应设备ID后，客户端才可以进行连接服务的操作（'connectAbility'）；
+2. 在连接服务成功的情况下，客户端才可进行发送信息的操作（'sendRequest_string'）；
+3. 在双方建立连接的情况下，客户端才可进行断连的操作（'disconnectAbility'）。
+
+## 约束与限制
+
+1. 本示例仅支持标准系统上运行，支持设备：RK3568。
+
+2. 本示例推荐使用DevEco Studio 5.0.2 Beta1 (Build Version: 5.0.7.100 构建 2025年1月16日)及以上版本编译运行。
+
+3. 本示例需要使用@ohos.app.ability.ServiceExtensionAbility，该模块仅对系统应用开放，业务使用时，需自行替换当前工程中的SDK为FULL SDK。使用Full SDK时需要手动从镜像站点获取，并在DevEcoStudio中替换，具体操作可参考[替换指南](https://gitcode.com/openharmony/docs/blob/master/zh-cn/application-dev/faqs/full-sdk-switch-guide.md) 。
+
+4. 本示例使用了ServiceExtensionAbility，需要在module.json5中进行相应的配置。如下：
+
+在服务端entry下的module.json5中配置如下字段：[module.json5](../IPC_Stub/entry/src/main/module.json5)，参考第48-54行。
+
+  ```
+  "extensionAbilities": [
+    {
+      "name": "ServiceAbility",
+      "srcEntry": "./ets/serviceextability/ServiceExtAbility.ets",
+      "type": "service",
+      "exported": true,
+      "description": "service"
+    }
+  ]
+  ```
+
+## 下载
+
+如需单独下载本工程及服务端，执行如下命令：
+
+  ```
+    git init
+    git config core.sparsecheckout true
+    echo IPC/RPC_sendMessage/ > .git/info/sparse-checkout
+    git remote add origin https://gitcode.com/harmonyos_samples/guide-snippets.git
+    git pull origin master
+  ``` 
+
+## 安装问题（9568344）
+
+因上述应用的module.json5中extensionAbilities字段中type属性为service，普通的安装方法会报错，需要按照以下方式进行安装：
+
+1. 注释module.json5中extensionAbilities字段
+
+![](image/comment.png)
+
+2. 获取app_signature
+
+ ```
+   hdc shell bm dump -n <bundleName> | findstr finger
+ ```
+
+![](image/app_signature.png)
+
+3. 添加白名单
+
+将rk设备的install_list_capability.json配置文件拉取到本地
+
+  ```
+   hdc shell mount -o rw,remount /
+   hdc file recv /system/etc/app/install_list_capability.json   ---rk的方式
+  ```
+
+![](image/recv_install_list_capability.png)
+
+在拉下来的json文件中添加不能安装成功的应用，格式如下：
+
+  ```
+   {
+     "install_list": [
+        {
+          ......
+        },
+        {
+          "bundleName": "应用包名",
+          "app_signature" : ["上面获取的app_signature"],
+          "allowAppUsePrivilegeExtension": true
+        }
+     ]
+   }
+  ```
+
+![](image/configure.png)
+
+4. 将修改后的白名单推送到设备上进行替换并重启
+
+  ```
+    hdc shell mount -o rw,remount /
+    hdc file send install_list_capability.json /system/etc/app/install_list_capability.json  
+    hdc shell chmod 777 /system/etc/app/install_list_capability.json 
+    hdc shell reboot
+  ```
+
+5. 取消module.json5中extensionAbilities的相关注释，重新安装hap包
+
