aws python sdk send sns_golang使用aws lambda发送消息到sqs
lambda是amazon提供的无需管理服务器，可持续扩展，并且按量计费的函数即服务工具即Faas，目前支持 .NET, Go, Java, Nodejs, Python, Ruby语言
sqs(amazon simple queue service)是amazon提供的一种完全托管的消息队列服务，类似于rabbitmq, kafka等
目前需要通过lambda(消息生产者)->sqs(消息队列)->lambda(消息消费者) 来保证数据的可靠性
在此我们使用golang来发送消息到sqs，实现代码如下
package main
import (
"fmt"
"github.com/aws/aws-sdk-go/aws"
"github.com/aws/aws-sdk-go/aws/credentials"
"github.com/aws/aws-sdk-go/aws/session"
"github.com/aws/aws-sdk-go/service/sqs"
)
func main() {
SendToAwsSqs()
//SendToAwsSns()
}
// 发送消息到sqs
func SendToAwsSqs() {
// 区域
region := "cn-northwest-1"
// Initial credentials loaded from SDK's default credential chain. Such as
// the environment, shared credentials (~/.aws/credentials), or EC2 Instance
// Role. These credentials will be used to to make the STS Assume Role API.
sess := session.Must(session.NewSession())
// Create a SNS client with additional configuration
// 方式一: 使用文件证书位置默认为~/.aws/credentials
//svc := sqs.New(sess, aws.NewConfig().WithRegion(region))
// 方式二: 使用传参方式
creds := credentials.NewStaticCredentials(
"YourKeyId",
"YourKeySecret",
"",
)
svc := sqs.New(sess, &aws.Config{Credentials: creds, Region: aws.String(region)})
// sqs消息队列url
qURL := "YourSqsUrl"
result, err := svc.SendMessage(&sqs.SendMessageInput{
DelaySeconds: aws.Int64(10),
MessageAttributes: map[string]*sqs.MessageAttributeValue{
"Title": &sqs.MessageAttributeValue{
DataType: aws.String("String"),
StringValue: aws.String("The Fidding"),
},
"Author": &sqs.MessageAttributeValue{
DataType: aws.String("String"),
StringValue: aws.String("Fidding"),
},
"WeeksOn": &sqs.MessageAttributeValue{
DataType: aws.String("Number"),
StringValue: aws.String("6"),
},
},
MessageBody: aws.String("FIdding Hello World."),
QueueUrl: &qURL,
})
if err != nil {
fmt.Println("Error", err)
return
}
fmt.Println("Success", *result.MessageId)
}
执行后打印的结果为一串uuid
Success {
MD5OfMessageAttributes: "xxxxxx355ceb7658bcc4ac0xxxxxx",
MD5OfMessageBody: "xxxxxdb8be7251f5c91090xxxxxxx",
MessageId: "xxxxx-d81c-4499-b033-6b5axxxxxx"
}
说明消息已经成功发送到队列中了
