如果你使用lambda，SQS和一个事件源Map，那么你不需要手动从sqs中删除对象：When your function successfully processes a batch, Lambda deletes its messages from the queue
只需返回一个成功代码，消息就会自动从相关SQS队列中删除

您可以从其ARN（在事件中为EventSourceARN）重新构建队列URL。

package main

import (
    "context"
    "fmt"

    "github.com/aws/aws-lambda-go/events"
    "github.com/aws/aws-lambda-go/lambda"
    "github.com/aws/aws-sdk-go/aws/arn"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/sqs"
)

var client *sqs.SQS

func main() {
  client = sqs.New(session.Must(session.NewSessionWithOptions(session.Options{
        SharedConfigState: session.SharedConfigEnable,
    })))
    lambda.Start(Handle)
}

func Handle(ctx context.Context, event events.SQSEvent) {  
    for _, record := range event.Records {
        // Process message
        fmt.Printf(record.Body)

        // Rebuild Queue URL from ARN 
        queueArn, _ := arn.Parse(record.EventSourceARN)
        queueUrl := fmt.Sprintf("https://sqs.%v.amazonaws.com/%v/%v", queueArn.Region, queueArn.AccountID, queueArn.Resource)

        // Delete message from queue
        client.DeleteMessage(&sqs.DeleteMessageInput{
            QueueUrl:      &queueUrl,
            ReceiptHandle: &record.ReceiptHandle,
        })
    }
}

如果您使用的是非标准AWS分区（例如中国），您还需要更改URL的根域以匹配。
