[英]Unable to deploy the Node.js AWS Lambda function to Docker
我正在使用 Node.Js 開發 REST API。 我的技術棧是 AWS Lambda、API Gateway 和 RDS (MySQL)。 下面是我的代碼
角色.js
const mysql = require('mysql');
const con = mysql.createConnection({
host : "*****.rds.amazonaws.com",
user : "*****",
password : "*****",
port : 3306,
database : "******"
});
exports.lambdaHandler = (event, context, callback) => {
// allows for using callbacks as finish/error-handlers
context.callbackWaitsForEmptyEventLoop = false;
const sql = "select * from role";
con.query(sql, function (err, result) {
if (err) throw err;
var response = {
"statusCode": 200,
"headers": {
"Content-Type": "application/json"
},
"body": JSON.stringify(result),
"isBase64Encoded": false
};
callback(null, response)
});
};
exports.selectRoleByIDHandler = (event, context, callback) => {
const { id } = event.queryStringParameters;
console.log("id", id);
// allows for using callbacks as finish/error-handlers
context.callbackWaitsForEmptyEventLoop = false;
const sql = "select * from role where idRole = "+id;
con.query(sql, function (err, result) {
if (err) throw err;
var response = {
"statusCode": 200,
"headers": {
"Content-Type": "application/json"
},
"body": JSON.stringify(result),
"isBase64Encoded": false
};
callback(null, response)
});
};
下面是我的template.yaml

當我嘗試執行sam local invoke
,出現以下錯誤
Error: You must provide a function logical ID when there are more than one functions in your template. Possible options in your template: ['HelloWorldFunction', 'RoleFunction', 'SelectRolesByIDFunction']
現在,我有兩個問題。
看起來您正在嘗試通過適用於 Javascipt 的 AWS 開發工具包構建 Lambda 函數。 您是否看過AWS SDK for JavaScript V3 DEV Guide中的 AWS 示例。 關於如何使用 JS API 構建 Lambda 函數的端到端說明可以為您提供幫助。
請參閱此主題和 TOC 中的子主題:
我發現了這個問題,我不得不像sam local invoke HelloWorldFunction
一樣sam local invoke HelloWorldFunction
。 HelloWorldFunction
是我需要部署的函數名稱。
