10. 保存上述配置
![554,295](https://img-blog.csdnimg.cn/20200326163750572.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

11．修改dht11_sample.c，修改头文件‘drv_gpio.h’为’board.h’, 删除static void read_temp_entry(void *parameter)和static int dht11_read_temp_sample(void)函数，将读取温湿度的流程放到mqtt_sample.c中
![524,295](https://img-blog.csdnimg.cn/20200326163819319.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

12．          修改mqtt_sample.c，添加DHT11读取温湿度，并通过Topic：/${ProductSN}/${DeviceSN}/upload/event  publish消息到Ucloud物联网云平台- 添加头文件
![522,295](https://img-blog.csdnimg.cn/20200326163916238.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

![30cb5d44e276505b1d4c053c8b25525da228db30.gif](https://oss-club.rt-thread.org/uploads/data-image-base64/30cb5d44e276505b1d4c053c8b25525da228db30.gif)

- 修改static int _publish_msg(void*client, msg_payload payload) 函数上报温湿度
![526,295](https://img-blog.csdnimg.cn/20200326163953991.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

- 在static void mqtt_test_thread(void)函数中添加DHT11温湿度读取代码
![522,295](https://img-blog.csdnimg.cn/20200326164039145.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

![30cb5d44e276505b1d4c053c8b25525da228db30.gif](https://oss-club.rt-thread.org/uploads/data-image-base64/30cb5d44e276505b1d4c053c8b25525da228db30.gif)

![526,295](https://img-blog.csdnimg.cn/20200326164051894.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

![30cb5d44e276505b1d4c053c8b25525da228db30.gif](https://oss-club.rt-thread.org/uploads/data-image-base64/30cb5d44e276505b1d4c053c8b25525da228db30.gif)

- 修改void mqtt_test_example (void)，并创建一个头文件声明该函数
![526,295](https://img-blog.csdnimg.cn/20200326164141782.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

![30cb5d44e276505b1d4c053c8b25525da228db30.gif](https://oss-club.rt-thread.org/uploads/data-image-base64/30cb5d44e276505b1d4c053c8b25525da228db30.gif)

![522,295](https://img-blog.csdnimg.cn/20200326164206853.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

**注：**mqtt_sample.c完成的工作包括：①监听MQTT Topic：/${ProductSN}/${DeviceSN}/upload/event ；②发送消息到MQTT Topic：/${ProductSN}/${DeviceSN}/upload/event。mqtt_sample.c中为了方便观察测试结果，使用的Topic同时具有发布&订阅权限，实际使用中建议参考【Topic管理】([https://docs.ucloud.cn/iot/uiot-core/console_guide/product_device/topic](https://docs.ucloud.cn/iot/uiot-core/console_guide/product_device/topic))分别定义发布、订阅权限的Topic用于上下行通信。  
       -在main函数中调用void mqtt_test_example (void)

![521,295](https://img-blog.csdnimg.cn/20200326164256887.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

13．编译并下载到目标开发板
![554,293](https://img-blog.csdnimg.cn/20200326164333471.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0ZJTExNT1JFYWQ=,size_16,color_FFFFFF,t_70)

14．打开UIoT物联网日志功能，可以查看上行消息

规则引擎转发到http server-       准备httpserver，本例使用golang写一个监听8900，path为receive的http server，并将收到的数据打印```-       package main

import (

"encoding/hex"

"fmt"

"io/ioutil"

"net/http"

)

func IndexHandler(w http.ResponseWriter, r *http.Request) {

s,_ := ioutil.ReadAll(r.Body)

//fmt.Println(time.Now().Local().String()+string(s))

hexdump := hex.Dump(s)

fmt.Print(hexdump)

}

func main() {

http.HandleFunc("/receive", IndexHandler)

http.ListenAndServe(":8900", nil)

}
 ```

-       配置规则引擎
