使用Golang-AWS-SDK IoTDataPlane向AWS IoT發送HTTP POST

Question

我想通過HTTP使用AWS-SDK在golang中通過AWS IoT向MQTT主題發送消息，
當嘗試下面的代碼時，它是不成功的。 答復是：

ResourceNotFoundException: Not Found
status code: 404, request id: 3d2c0f11-09f6-4e86-94bf-ea877a30ebcd

以下是我使用的代碼：

package main


import (
        "github.com/aws/aws-sdk-go/aws"
        "github.com/aws/aws-sdk-go/aws/session"
        "github.com/aws/aws-sdk-go/service/iotdataplane"
        "fmt"
)


func main(){
svc := iotdataplane.New(session.New(), &aws.Config {Region: aws.String("us-west-2"), Endpoint: aws.String("https://YOUR_PREFIX.iot.us-west-2.amazonaws.com")})

params := &iotdataplane.PublishInput{
        Topic:   aws.String("mytopic"), // Required
        Payload: []byte("PAYLOAD"),
        Qos:     aws.Int64(0),
}
resp, err := svc.Publish(params)

if err != nil {
        // Print the error, cast err to awserr.Error to get the Code and
        // Message from an error.
        fmt.Println(err.Error())
        return
}

// Pretty-print the response data.
fmt.Println(resp)

我還驗證了我的AWS賬戶驗證了有效的憑據設置和策略。 以下是〜/ .aws / credentials中的aws憑據

[default]
aws_access_key_id = YOUR_ACCESS_KEY_ID
aws_secret_access_key = YOUR_SECRET_ACCESS_KEY

和政策附加到您的身份：

{
"Version": "2012-10-17",
"Statement": [
    {
        "Effect": "Allow",
        "Action": [
            "iot:*"
        ],
        "Resource": "*"
   }
]

}

我也試過Node.JS它的工作原理!! 以下是Node中的WORKING源以供參考：

var    AWS = require('aws-sdk');

AWS.config.update({region: 'us-west-2'});
var iotdata = new AWS.IotData({endpoint: 'YOUR_PREFIX.iot.us-west-2.amazonaws.com'});


var params = {
  topic: 'mytopic', /* required */
  payload: new Buffer('hello') || 'STRING_VALUE',
  qos: 0
};

iotdata.publish(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

對於Node JS工作，它需要在根文件夾中有適當的AWS.config文件。 像這樣：

accessKeyId = YOUR_ACCESS_KEY_ID
secretAccessKey = YOUR_SECRET_ACCESS_KEY

如果仍與任何人相關...請使用aws.Config中的Credentials * credentials.Credentials
