 The  **Request**  and  **Response**  classes define the requests and responses used for communication between the AI engine server and algorithm plug-ins. A request encapsulates the request content and input data of the caller. The plug-in returns the calculation result to the AI engine server through a response.
 
 [Table 3](#table16273647125120)  describes the attributes of the  **Request**  class.

 Request、Response是ai引擎服务端与算法插件进行通信的对象。Request封装了调用方的请求、输入数据等，而插件主要通过Response将运算之后的结果返回给AI引擎服务端。
 
 Request类的属性如下[表3](#table16273647125120)所示。
