 # WantAgent开发指导
-### 简介
-wantAgent封装了一个指定行为的意图，可以通过wantAgent.trigger接口主动触发，也可以通过与通知绑定被动触发。
+### 场景简介
+WantAgent封装了一个行为意图信息，可以通过WantAgent.trigger接口主动触发，也可以通过与通知绑定被动触发。
 
-具体的行为包括：启动ability和发布公共事件。

 ### 接口说明
 | 接口名                                                                                          | 接口描述 |
 | ---------------------------------------------------------------------------------------------- | ----------- |
-| wantAgent.getWantAgentInfo(info: WantAgentInfo, callback: AsyncCallback\<WantAgent\>) | 创建wantAgent对象(callback) |
-| wantAgent.getWantAgent(info: WantAgentInfo): Promise\<WantAgent\>; | 创建wantAgent对象(promise) |
-| commonEvent.trigger(agent: WantAgent, triggerInfo: TriggerInfo, callback?: Callback\<CompleteData\>) | 触发wantAgent |
+| getWantAgentInfo(info: WantAgentInfo, callback: AsyncCallback\<WantAgent\>) | 以AsyncCallback形式创建WantAgent对象 |
+| getWantAgent(info: WantAgentInfo): Promise\<WantAgent\> | 以Promise形式创建WantAgent对象 |
+| trigger(agent: WantAgent, triggerInfo: TriggerInfo, callback?: Callback\<CompleteData\>) | 触发WantAgent |
 
 ### 开发步骤
 1. 导入WantAgent模块。
 
-```javascript
-import wantAgent from '@ohos.wantAgent';
-```
+   ```
+   import wantAgent from '@ohos.wantAgent';
+   ```
+   
+2. 创建拉起Ability的WantAgentInfo信息，详细的WantAgentInfo信息数据类型及包含的参数请见[WantAgentInfo文档](../reference/apis/js-apis-wantAgent.md#wantagentinfo)介绍。

+   ```
+   private wantAgentObj = null	//用于保存创建成功的wantAgent对象，后续使用其完成触发的动作。
+   
+   //wantAgentInfo
+   var wantAgentInfo = {
+       wants: [
+           {
+               deviceId: "",
+               bundleName: "com.example.test",
+               abilityName: "com.example.test.MainAbility",
+               action: "",
+               entities: [],
+               uri: "",
+               parameters: {}
+           }
+       ],
+       operationType: OperationType.START_ABILITY,
+       requestCode: 0,
+       wantAgentFlags:[WantAgentFlags.CONSTANT_FLAG]
+   }
+   ```
 
-```javascript
-private wantAgentObj = null	//用于保存创建成功的wantAgent对象，后续使用其完成触发的动作
+3. 创建发布公共事件的WantAgentInfo信息
 
-//wantAgentInfo
-var wantAgentInfo = {
-    wants: [
-        {
-            deviceId: "",
-            bundleName: "com.example.test",
-            abilityName: "com.example.test.MainAbility",
-            action: "",
-            entities: [],
-            uri: "",
-            parameters: {}
-        }
-    ],
-    operationType: OperationType.START_ABILITY,
-    requestCode: 0,
-    wantAgentFlags:[WantAgentFlags.CONSTANT_FLAG]
-}
-```
+   ```
+   private wantAgentObj = null	//用于保存创建成功的WantAgent对象，后续使用其完成触发的动作。
+   
+   //wantAgentInfo
+   var wantAgentInfo = {
+       wants: [
+           {
+               action: "event_name", // 设置事件名
+               parameters: {}
+           }
+       ],
+       operationType: OperationType.SEND_COMMON_EVENT,
+       requestCode: 0,
+       wantAgentFlags:[WantAgentFlags.CONSTANT_FLAG]
+   }
+   ```

-```javascript
-//创建wantAgent
-wantAgent.getWantAgent(wantAgentInfo, (err, wantAgentObj) => {

-        console.error("[WantAgent]getWantAgent err=" + JSON.stringify(err))
-    } else {
-        console.log("[WantAgent]getWantAgent success")
-        this.wantAgentObj = wantAgentObj
-    }
-})
-```
+   ```
+   //创建WantAgent
+   wantAgent.getWantAgent(wantAgentInfo, (err, wantAgentObj) => {
