我正在尝试设置对 SNS 主题的订阅,我在 SNS UI 中添加了 HTTP 订阅,它被标记为“待确认”。我已经设置了我的端点来查找正确的 header (如下所示)并且它正在工作。我的问题是端点永远不会获得“ token ”,请参阅下面我的代码和日志的输出。

用于测试的 NodeJS(w/express 4.15)代码:

router.post('/', (req, res, next) => {
console.log('-----------------')
console.log(req.body)
console.log(req.headers)
console.log('-----------------')
if (req.get('x-amz-sns-message-type') == "SubscriptionConfirmation") {
SNS.confirmSubscription({ Token: req.body.Token, TopicArn: req.get('x-amz-sns-topic-arn') }, (err, finished) => {
if (err) console.log(err)
})
} else {
console.log(req.body)
}
})

来自 AWS 的 POST 请求

在上面,您会看到 req.body 是空的,并且设置了 header ,但没有包含 Token。有人可以指出我做错了什么吗?

最佳答案

您必须明确通知 express 对此端点使用文本解析。

试试这个:

    const express = require('express');
const router = express.Router();
const request = require('request');
var bodyParser = require('body-parser')


router.post('/',bodyParser.text(),handleSNSMessage);
module.exports = router;


var handleSubscriptionResponse = function (error, response) {
if (!error && response.statusCode == 200) {
console.log('Yess! We have accepted the confirmation from AWS');
}
else {
throw new Error(`Unable to subscribe to given URL`);
//console.error(error)
}
}
async function handleSNSMessage(req, resp, next) {

try {
let payloadStr = req.body
payload = JSON.parse(payloadStr)
console.log(JSON.stringify(payload))
if (req.header('x-amz-sns-message-type') === 'SubscriptionConfirmation') {
const url = payload.SubscribeURL;
await request(url, handleSubscriptionResponse)
} else if (req.header('x-amz-sns-message-type') === 'Notification') {
console.log(payload)
//process data here
} else {
throw new Error(`Invalid message type ${payload.Type}`);
}
} catch (err) {
console.error(err)
resp.status(500).send('Oops')
}
resp.send('Ok')
}

编辑:从 express v4.17.0 开始,您可以使用 express.text() 中间件本身,而不是 bodyParser.text()。看看this official doc

注意:我没有使用 app.use,因为这会影响我的所有其他端点。
