Javascript 测试Lambda函数时,index.handler未定义或未导出
我有一个JS脚本Javascript 测试Lambda函数时,index.handler未定义或未导出,javascript,amazon-web-services,aws-lambda,Javascript,Amazon Web Services,Aws Lambda,我有一个JS脚本index.JS,它接受一个变量输入ipAddress,但它给了我以下错误: { "errorType": "Runtime.HandlerNotFound", "errorMessage": "index.handler is undefined or not exported", "trace": [ "Runtime.HandlerNotFoun
index.JS
,它接受一个变量输入ipAddress
,但它给了我以下错误:
{
"errorType": "Runtime.HandlerNotFound",
"errorMessage": "index.handler is undefined or not exported",
"trace": [
"Runtime.HandlerNotFound: index.handler is undefined or not exported",

该脚本在本地工作:
> node index.js 158.140.127.123
Found ipAddress match
Bucket uploaded successfully at /blocklist-158.140.127.123
但在将zip导入Lambda时不是这样
更新:index.js内容:
// Usage: index.js x.x.x.x
'use strict';
const AWS = require('aws-sdk');
AWS.config.update({
region: "us-east-1"
});
// Get ipAddress from user argument (will eventually get input from sns)
var ipAddress = process.argv[2]
// Get geolocation from ipAddress
function getIpAddressGeo(ipAddress) {
const geoip = require('geoip-lite');
var geo = geoip.lookup(ipAddress);
return geo;
};
async function getIpMatchBool() {
const request = require('request');
const promise = require('promise');
var lookupUrl = "https://raw.githubusercontent.com/firehol/blocklist-ipsets/master/bi_sip_0_1d.ipset";
// This should only create a bucket if getIpMatchBool returns true
function createS3IpListing(ipAddress) {
var date = Date.now();
const s3 = new AWS.S3({
apiVersion: '2006-03-01',
accessKeyId: process.env.AWS_ACCESS_KEY,
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY
});
const bucketParams = {
Bucket: `blocklist-${ipAddress}`
};
s3.createBucket(bucketParams, function(err, data) {
if (err) {
console.log("Error", err);
} else {
console.log(`Bucket uploaded successfully at ${data.Location}`);
}
});
// createFile not returning - working on this now
const createFile = (geo = getIpAddressGeo()) => {
const fs = require('fs');
fs.readFile(date, (err, data) => {
if (err) throw err;
const params = {
Bucket: bucketParams.Bucket,
Key: date,
Body: JSON.stringify(data, geo)
};
s3.upload(params, function(s3Err, data) {
if (s3Err) throw s3Err
console.log(`File uploaded successfully at ${data.Location}`)
});
});
return createFile(geo)
};
};
// This RegEx does not account for the differance between 10 & 10.x.x.x - need to fix
var re = new RegExp(ipAddress.replace(/\./g, '\\.'), 'gi');
const issueRequest = () => {
return new promise(() => {
request(lookupUrl, function(error, response, body) {
if (!error && response.statusCode == 200) {
if (body.search(re) == -1) {
console.log("No ipAddress match");
} else {

}
}
})
});

getIpMatchBool(ipAddress)
我认为您不能通过process.arg访问变量。尝试将exports.handler与事件参数一起使用。默认情况下,lambda函数返回/执行处理程序。您可以找到文档您可以发布
index.js
的内容吗?您是否在index.js
文件中定义了处理程序
函数?@jellycsc刚刚用index.js更新了它contents@JohnRotenstein我不相信我有你必须出口处理程序。我认为这是必须的。我还尝试了以下的一些变体exports.handler=async function(event){return getIpMatchBool(ipAddress)}
和receive找不到模块“exports”
。。。真奇怪。尝试在GUI中修改一个空白lambda,而不是上传自己的lambda,看看它是否仍然抛出该错误。可能您没有正确导出它。只需修改现有模板,因为它已经正确定义了导出。
