 ## 神女授书（4）
 
-待定
+参照 [请求响应文档](https://www.emqx.com/zh/blog/mqtt5-request-response)，发送附带`ResponseTopic`，并订阅`ResponseTopic`
+，才能接收到响应结果
+
+### RequestPayload
 
 ```json lines
 {
+  // 发卡执行时间，单位秒
+  "action": 0,
+  // 等待时间，单位秒
+  "wait": 10
 }
 ```
 
+### ResponsePayload
+
+```json lines
+{
+  // 空卡设备数量
+  "empty": 0,
+  // 错误设备数量
+  "error": 0,
+  // 发卡是否成功，1为成功，0为失败
+  "out_ok": 0
+}
+```
+
+若`out_ok`，`empty`，`error`都为`0`，很有可能两台机器发卡口都被堵住了，需要人工处理。
+
+发卡口堵住不属于`error`，不会在`error`里计数体现。
