AWS IoT SDK-主要的L#206错误订阅:-28(C代码) [英] AWS IoT SDK - main L#206 Error subscribing : -28 (C code)

问题描述

我正在尝试在本教程来自AWS IoT(AWS IoT嵌入式C SDK).

I am trying to run the example in this tutorial from AWS IoT (AWS IoT Embedded C SDK).

我的aws_iot_config.h文件具有以下配置:

My aws_iot_config.h file has the following configuration:

#define AWS_IOT_MQTT_HOST              "XXXXXXX.iot.us-east-2.amazonaws.com" ///< Customer specific MQTT HOST. The same will be used for Thing Shadow
#define AWS_IOT_MQTT_PORT              8883 ///< default port for MQTT/S
#define AWS_IOT_MQTT_CLIENT_ID         "c-sdk-client-id" ///< MQTT client ID should be unique for every device
#define AWS_IOT_MY_THING_NAME          "SM1" ///< Thing Name of the Shadow this device is associated with
#define AWS_IOT_ROOT_CA_FILENAME       "iotRootCA.pem" ///< Root CA file name
#define AWS_IOT_CERTIFICATE_FILENAME   "deviceCert.crt" ///< device signed certificate file name
#define AWS_IOT_PRIVATE_KEY_FILENAME   "deviceCert.key" ///< Device private key filename

这是我的政策:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iot:Connect",
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": "iot:Publish",
      "Resource": "arn:aws:iot:us-east-2:338639570104:topic/sm1"
    },
    {
      "Effect": "Allow",
      "Action": "iot:Subscribe",
      "Resource": "arn:aws:iot:us-east-2:338639570104:topic/sm1"
    }
  ]
}

运行subscribe_publish_sample示例时，出现以下错误:

When I run the subscribe_publish_sample example, I am getting the following error:

任何人都可以告诉我发生了什么事吗?我想念什么吗?

Can anyone show me what is happening? Am I missing something?

推荐答案

由于我没有找到与将数据从设备发送到AWS IoT的过程相关的良好且完整的教程，包括所有必要步骤，因此我尝试更改我以前用来执行的政策:

As I did not find out a good and complete tutorial related to process of sending data from a device to AWS IoT, including all the steps needed, I tried changing the policy I was using to:

{
  "Effect": "Allow",
  "Action": "iot:*",
  "Resource": "*"
}

尽管Resource上的通配符显然不是很好，但这是我使用的方式，因为其他策略均无效.

Though this wildcard on Resource apparently is not so good, it was the way I used, since the other policies were not working.
