基于stm32f103zet6的bc260模块数据上传阿里云服务器的代码

您可以参考以下代码实现基于stm32f103zet6的bc260模块数据上传阿里云服务器：

#include <stdio.h>
#include "net.h"
#include "iot_import.h"
#include "iot_export.h"

/* 以下参数需根据实际情况填写 */
#define product_key      "your_product_key"
#define device_name      "your_device_name"
#define device_secret    "your_device_secret"
#define region           "cn-shanghai"          // 阿里云服务器地区
#define endpoint         "iot-as-http2.cn-shanghai.aliyuncs.com"  // 阿里云服务器域名

static int iotx_example_subdev_publish(void *param) {
    /* 建立MQTT连接 */
    mqtt_client_t mqtt_client = NULL;
    mqtt_connect_init_params_t mqtt_params = DEFAULT_MQTT_CONNECT_INIT_PARAMS;
    mqtt_params.client_id = "example_subdev_publish";
    mqtt_params.username = device_name;
    mqtt_params.password = device_secret;

    disconnect_params_t disconnect_params = DEFAULT_DISCONNECT_PARAMS;

    int rc = IOT_MQTT_Construct(&mqtt_client, endpoint, product_key, device_name, device_secret, &mqtt_params);
    IOT_TEST_CHECK(rc == 0, -1);

    /* 设置topic */
    const char *pub_topic = "/sys/"product_key"/"device_name"/thing/event/property/post";

    /* 组装json格式的消息 */
    char message[1024];
    memset(message, 0, 1024);
    int raw_data_size = snprintf(message, 1024, "{\"id\":123,\"version\":\"1.0\",\"params\":{\"Temperature\": %d, \"Humidity\":%d},\"method\":\"thing.event.property.post\"}", 25, 50);

    /* 发布消息 */
    rc = IOT_MQTT_Publish(mqtt_client, pub_topic, (uint8_t *) message, raw_data_size);
    IOT_TEST_CHECK(rc >= 0, -1);

    printf("example_subdev_publish Successfully: %d\n", raw_data_size);

    /* 断开MQTT连接 */
    IOT_MQTT_Destroy(&mqtt_client);

    return 0;
}

int main(int argc, char **argv) {
    /* 初始化网络 */
    IOT_OpenLog("iot");
    IOT_SetLogLevel(IOT_LOG_DEBUG);
    IOT_SetupConnInfo(region, product_key, device_name, device_secret);

    int rc = HAL_Init();
    IOT_TEST_CHECK(rc == 0, -1);

    rc = HAL_SleepMs(200);
    IOT_TEST_CHECK(rc == 0, -1);

    rc = HAL_Timer_Init();
    IOT_TEST_CHECK(rc == 0, -1);

    rc = network_init();
    IOT_TEST_CHECK(rc == 0, -1);

    /* 发布消息到阿里云服务器 */
    iotx_example_subdev_publish(NULL);
}

该代码通过MQTT协议实现数据上传阿里云服务器，其中包括建立MQTT连接、设置topic、组装json格式的消息、发布消息等步骤。其中，您需要填写与您的设备相关的参数，包括product_key、device_name、device_secret、region和endpoint等。
