Question

我正在尝试在 Windows 上使用 dockerized postgres + nodejs connction 做一个简单的入门练习。我跑了：

$ docker run -d --name dev-postgres -e POSTGRES_PASSWORD=testpw  -p 5432:5432 postgres      
701682e86a66f7efb81af2ebb3a92d442c52742d2cd3d008de690bf1fa73d896

然后使用 pg 库中的以下代码段：

const { Client } = require("pg");
const connectionString = "postgresql://postgres:testpw@localhost:5432/postgres";

const client = new Client({
  connectionString,
});
client.connect();

client.query("SELECT $1::text as message", ["Hello world!"], (err, res) => {
  console.log(err ? err.stack : res.rows[0].message); // Hello World!
  client.end();
});

但它崩溃了：

(node:8764) UnhandledPromiseRejectionWarning: error: password authentication failed for user "postgres"

我尝试了几种不同的方法来使配置正常工作，但还没有成功。任何人都可以发现我做错了什么吗？这是 Windows 的问题吗？我使用 exec bash 检查了 docker 容器，并且可以使用 psql 在容器内没有任何问题。感谢您的帮助！

明智之举 - 事实证明，在 Windows 上，如果您有另一个 postgres 实例在 5432 上运行，则会以这种方式失败。我的解决方案是简单地停止该实例。不幸的是，由于它是在系统启动时启动的后台进程，所以我花了一段时间才弄清楚它在那里。
