我正在尝试通过lambda发送publish sns命令，但不会发送 [英] I am trying to send a publish sns command via lambda however it will not send

问题描述

在过去的几天里，我一直在尝试发布sns，但是无论我编写什么代码，我都无法将其发送出去.请注意，我不是编码员，我只是为了好玩而已.

I have been trying for the past days to publish a sns however no matter what i code i just cant get it to send. Be aware i am not a coder, i just do this for fun.

我已经按照以下步骤设置了IAM策略和规则，并使用策略模拟器运行了它，效果很好.

I have set up an IAM policy and rule as below and ran it with the policy simulator and it works fine.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sns:Publish",
            "Resource": "arn:aws:sns:us-east-1:*******:CallBell"
        }
    ]
}

我在代码的开头有这个.

i have this at the beginning of my code.

var AWS = require("aws-sdk");
var sns = new AWS.SNS();

然后我将这部分代码包含在我的函数意图之内(这是一种Alexa技能)

I than have this part of the code within my function intent (this is an alexa skill)

console.log("Loading function");
sns.publish({
Message: 'Test', 
Subject: 'Test SNS From Lambda',
TopicArn: 'arn:aws:sns:us-east-1:*******:CallBell'
});
console.log("Message Sent");

这让我发疯，需要帮助，我检查了我的日志和加载"功能并发送了消息，但没有出现任何错误，但是我没有收到消息.请帮忙！

This is driving me nuts and need help, I check my log and the Loading function and Message sent and it doesn't give any error however i don't get my messages. Please help!!

推荐答案

如果您在VPC中设置lambda，则它不会路由您的SNS请求.删除VPC后，再试一次.如果您确实需要VPC，则可以在VPC中添加NAT服务，以使lambda能够访问Internet，如

If you set your lambda in a VPC, then it wont route your SNS request. Try again once you remove VPC. If you really need a VPC, you can add a NAT service in your VPC to enable your lambda to have internet access, as explained here.
