向AWS IOT Shadows发送数据ESP8266时出现“无法设置尝试发送数据的SSL连接”错误消息

Question

我正在尝试发送一个测试值到AWS IOT Shadows，但是当我将它上传到我的设备时，它总是说"Cant Setup SSL ConnectionTrying to send Data“。请帮助我将此值发送给AWS IOT Shaodws！我已尝试将ARN更改为HTTPS端点ARN。并不断收到此错误消息。

#include <ESP8266WiFi.h>
#include <AmazonIOTClient.h>
#include <ESP8266AWSImplementations.h>

Esp8266HttpClient httpClient;
Esp8266DateTimeProvider dateTimeProvider;

AmazonIOTClient iotClient;
ActionError actionError;

const char* ssid = "xxx";
const char* password = "xxx";

void initWLAN()
{
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED)
  {
    delay(500);
  }
}

void initAWS()
{
  iotClient.setAWSRegion("ap-southeast-2");
  iotClient.setAWSEndpoint("amazonaws.com");
  iotClient.setAWSDomain("arn:aws:iot:ap-southeast-2:489747887701:thing/IoTTestDevice");
  iotClient.setAWSPath("/things/IoTTestDevice/shadow");
  iotClient.setAWSKeyID("the-id");
  iotClient.setAWSSecretKey("the-secret-key");
  iotClient.setHttpClient(&httpClient);
  iotClient.setDateTimeProvider(&dateTimeProvider);
}

void setup() {
  Serial.begin(115200);
  delay(10);
  Serial.println("begin");
  initWLAN();
  Serial.println("wlan initialized");
  initAWS();
  Serial.println("iot initialized");
}

void loop()
{
  char shadow[100];
  strcpy(shadow, "{\"state\":{\"reported\":{\"test_value1\":123, \"test_value2\":234}}}");

  Serial.println("Trying to send data");
  Serial.print(shadow);

  char* result = iotClient.update_shadow(shadow, actionError);
  Serial.print(result);

  delay(10000);
}

继续收到此错误消息。

12:31:04.295 -> can't setup SSL connectionTrying to send data

请帮帮我！谢谢

Answer 1

setAWSDomain()需要API终结点，而不是ARN。

Here is an example。

要查找API端点，请在控制台中选择设备，方法是进入IoT > Manage > Things > ThingName > Interact并找到HTTPS端点。

或者，您可以从AWS CLI使用describe-endpoint命令。

Answer 2

如上所述，需要使用您的端点更新以下行：

From:
iotClient.setAWSDomain("arn:aws:iot:ap-southeast-2:489747887701:thing/IoTTestDevice");

To:
iotClient.setAWSDomain("axxxxxxxxxxxxz-ats.iot.ap-southeast-2.amazonaws.com");

即使解决了这个问题，并假设您的esp8266主板版本大于2.3.0和低于2.6.0，您可能仍然会遇到相同的问题:-(

FWIW，esp8266 2.3.0主板版本将连接到aws iot，但应用程序崩溃出现了不同的问题(参考：https://github.com/esp8266/Arduino/issues/4811)。我还没能找到一个解决方案...还有谁成功了吗？
