Node JS中的Lambda函数在Visual Studio代码中使用SAM插件并尝试连接到PG实例

如何解决Node JS中的Lambda函数在Visual Studio代码中使用SAM插件并尝试连接到PG实例

嗨，我正在使用sam插件在vscode中运行lambda代码。节点js 12.x中使用的运行时。在本地postgresql实例中使用的数据库。通过SAM无法连接到数据库。我的代码正在安装了docker台式机的Windows 10笔记本电脑上运行。

'use strict';
var pg      = require('pg');
var connection = new pg.Client({
  host     : 'localhost',user     : 'postgres',password : 'admin',database : 'logtest'
});

module.exports.hello = (event,context,callback) => {
  
  connection.connect();

  connection.query('SELECT 1 + 1 AS solution',function (error,results,fields) {
    if (error) throw error;
    console.log('The solution is: ',results[0].solution);
    const response = {
      statusCode: 200,body: JSON.stringify({
        message: 'Go Serverless v1.0! Your function executed successfully!',solution: results[0].solution,}),};

    connection.end();

    callback(null,response);    
  });
};

我得到的错误是

我尝试使用docker.for.win.localhost和host.docker.internal而不是localhost，但是没有成功。
