1. 参考网址：https://forum.openmediavault….

2. 创建应用GUI
   创建应用目录：/var/www/openmediavault/js/omv/module/admin/service/example
   创建菜单节点： Node.js

   ```

   // require("js/omv/WorkspaceManager.js")
   OMV.WorkspaceManager.registerNode({
   id: 'example',
   path: '/service',
   text: _('Example'),
   icon16: 'images/example.png',
   iconSvg: 'images/example.svg'
   });
   ```

   设置菜单节点图标
   var/www/openmediavault/images 内创建对应Node.js内的2张图片

   创建设置面板: Settings.js

   ```

   // require("js/omv/WorkspaceManager.js")
   // require("js/omv/workspace/form/Panel.js")
   Ext.define('OMV.module.admin.service.example.Settings', {
   extend: 'OMV.workspace.form.Panel',

   rpcService: 'Example',
   rpcGetMethod: 'getSettings',
   rpcSetMethod: 'setSettings',

   getFormItems: function() {
   return [{
   xtype: 'fieldset',
   title: _('General'),
   fieldDefaults: {
   labelSeparator: ''
   },
   items: [{
   xtype: 'checkbox',
   name: 'enable',
   fieldLabel: _('Enable'),
   checked: false
   },
   {
   xtype: 'numberfield',
   name: 'max_value',
   fieldLabel: _('Max value'),
   minValue: 0,
   maxValue: 100,
   allowDecimals: false,
   allowBlank: true
   }]
   }];
   }
   });

   OMV.WorkspaceManager.registerPanel({
   id: 'settings',
   path: '/service/example',
   text: _('Settings'),
   position: 10,
   className: 'OMV.module.admin.service.example.Settings'
   });
   ```

   刷新js缓存：

   ```

   source /usr/share/openmediavault/scripts/helper-functions && omv_purge_internal_cache
   ```

3. 创建shell脚本
   生成配置信息的脚本postinst 命令执行：/bin/sh postinst configure

   ```

   #!/bin/sh

   set -e

   . /etc/default/openmediavault
   . /usr/share/openmediavault/scripts/helper-functions

   case "$1" in
   configure)
   SERVICE_XPATH_NAME="example"
   SERVICE_XPATH="/config/services/${SERVICE_XPATH_NAME}"

   # 添加默认配置
   if ! omv_config_exists "${SERVICE_XPATH}"; then
   omv_config_add_element "/config/services" "${SERVICE_XPATH_NAME}"
   omv_config_add_element "${SERVICE_XPATH}" "enable" "0"
   omv_config_add_element "${SERVICE_XPATH}" "max_value" "0"
   fi

   # 以下2条命令用于安装包安装 直接执行可注释掉
   dpkg-trigger update-fixperms
   dpkg-trigger update-locale
   ;;

   abort-upgrade|abort-remove|abort-deconfigure)
   ;;

   *)
   echo "postinst called with unknown argument" >&2
   exit 1
   ;;
   esac

   #DEBHELPER#

   exit 0
   ```

   创建删除配置信息的shell脚本 postrm 执行命令：/bin/sh postrm purge

   ```

   #!/bin/sh

   set -e

   . /etc/default/openmediavault
   . /usr/share/openmediavault/scripts/helper-functions

   SERVICE_XPATH_NAME="example"
   SERVICE_XPATH="/config/services/${SERVICE_XPATH_NAME}"

   case "$1" in
   purge)
   if omv_config_exists ${SERVICE_XPATH}; then
   omv_config_delete ${SERVICE_XPATH}
   fi
   ;;

   remove)
   ;;

   upgrade|failed-upgrade|abort-install|abort-upgrade|disappear)
   ;;

   *)
   echo "postrm called with unknown argument \\`$1'" >&2
   exit 1
   ;;
   esac

   #DEBHELPER#

   exit 0
   ```

4. 创建rpc
   在目录/usr/share/openmediavault/engined/rpc创建example.inc

   ```

   <?php
   class OMVRpcServiceExample extends \OMV\Rpc\ServiceAbstract {

   public function getName() {
   return "EXAMPLE";
   }

   public function initialize() {
   $this->registerMethod("getSettings");
   $this->registerMethod("setSettings");
   }

   public function getSettings($params, $context) {
   // Validate the RPC caller context.
   $this->validateMethodContext($context, [
   "role" => OMV_ROLE_ADMINISTRATOR
   ]);
   // Get the configuration object.
   $db = \\OMV\\Config\\Database::getInstance();
   $object = $db->get("conf.service.example");
   // Remove useless properties from the object.
   return $object->getAssoc();
   }

   public function setSettings($params, $context) {
   // Validate the RPC caller context.
   $this->validateMethodContext($context, [
   "role" => OMV_ROLE_ADMINISTRATOR
   ]);
   // Validate the parameters of the RPC service method.
   $this->validateMethodParams($params, "rpc.example.setsettings");
   // Get the existing configuration object.
   $db = \\OMV\\Config\\Database::getInstance();
   $object = $db->get("conf.service.example");
   $object->setAssoc($params);
   $db->set($object);
   // Return the configuration object.
   return $object->getAssoc();
   }
   }
   ```

   创建对应的配置文件
   在usr\share\openmediavault\datamodels创建conf.service.example.json

   ```

   {
   "type": "config",
   "id": "conf.service.example",
   "title": "EXAMPLE",
   "queryinfo": {
   "xpath": "//services/example",
   "iterable": false
   },
   "properties": {
   "enable": {
   "type": "boolean",
   "default": false
   },
   "max_value": {
   "type": "integer",
   "minimum": 1,
   "maximum": 100,
   "default": 0
   }
   }
   }
   ```

   在usr\share\openmediavault\datamodels创建rpc.example.json

   ```

   [{
   "type": "rpc",
   "id": "rpc.example.setsettings",
   "params": {
   "type": "object",
   "properties": {
   "enable": {
   "type": "boolean",
   "required": true
   },
   "max_value": {
   "type": "integer",
   "minimum": 1,
   "maximum": 100,
   "required": true
   }
   }
   }
   }]
   ```

   运行命令重启omv服务：service openmediavault-engined restart

5. 创建shell脚本获取配置信息
   创建执行脚本 example 执行命令：omv-mkconf example

   ```

   #!/bin/sh

   set -e

   . /etc/default/openmediavault
   . /usr/share/openmediavault/scripts/helper-functions

   OMV_EXAMPLE_XPATH="/config/services/example"
   OMV_EXAMPLE_CONF="/tmp/example.conf"

   cat < ${OMV_EXAMPLE_CONF}
   enable = $(omv_config_get "${OMV_EXAMPLE_XPATH}/enable")
   max_value = $(omv_config_get "${OMV_EXAMPLE_XPATH}/max_value")
   EOF

   exit 0
   ```

   为了监听触发执行脚本，将脚本放在/usr/share/openmediavault/mkconf目录下
   脚本权限改为 chmod 755 example

6. 配置保存事件监听

   /usr/share/openmediavault/engined/module创建监听的example.inc

   ```

   <?php
   class OMVModuleExample extends \OMV\Engine\Module\ServiceAbstract
   implements \OMV\Engine\Notify\IListener {
   public function getName() {
   return "EXAMPLE";
   }

   public function applyConfig() {
   // 触发对应执行脚本
   $cmd = new \\OMV\\System\\Process("omv-mkconf", "example");
   $cmd->setRedirect2to1();
   $cmd->execute();
   }

   function bindListeners(\\OMV\\Engine\\Notify\\Dispatcher $dispatcher) {
   $dispatcher->addListener(OMV_NOTIFY_MODIFY,
   "org.openmediavault.conf.service.example", // 和rpc内的配置文件一致conf.service.example
   [ $this, "setDirty" ]);
   }
   }
   ```

   运行命令重启omv服务：service openmediavault-engined restart

7. 创建deb包 https://blog.csdn.net/gatieme…
