# Action通讯模型 #

## Action通讯模型组成[¶][Link 1] ##

ROS中，节点与节点间通讯，提供了新的方式，就是Action通讯。

![format_png][]

Action通讯分为`Client端`和`Server端`，`Client端`负责给`Server端`发送指令，`Server`端接收到指令，根据自身的业务逻辑进行处理指令，处理过程中，可以反馈进度给为`Client端`，处理结束后将结构反馈给`Client端`。

![format_png 1][]

在Action通讯模型交互过程中，分为三个数据交互阶段：

*  `client端`请求阶段
 *  `server端`进度反馈阶段
 *  `server端`结果反馈阶段

对于`Client端`而言，可做的操作行为有两种:

*  发送指令请求
 *  取消指令请求

对于`Server`而言，可做的操作行为有：

*  响应进度信息
 *  响应结果信息

## Action交互过程中的专有名称[¶][Link 2] ##

### Goal 请求指令[¶][Link 3] ###

`client端`向`server端`发送请求时所带的数据，我们称之为Goal

### Feedback过程响应[¶][Link 4] ###

`server端`进度反馈阶段，反馈给`client端`的数据，我们称之为`Feedback`

### Result结果响应[¶][Link 5] ###

`server端`结果反馈阶段，反馈给`client端`的数据，我们称之为`Result`

### 设计艺术[¶][Link 6] ###

client端请求，server端响应，操作为异步的，通讯信息采用数据来规范，通过`Goal`，`Feedback`，`Result`规定了统一操作数据的规范。
