服务器不支持SSL连接node-postgres

Question

我正在尝试与本地 postgres 数据库建立连接并使用express 来执行api 端点。我不确定为什么会收到此错误。

//db.js

const { Pool } = require("pg");
const pg = require("pg");

require("dotenv").config(); //get credentials

pg.defaults.ssl = true;

const connectionString = process.env.NODE_ENV === "production"
  ? process.env.DATABASE_URL
  : `postgresql://${process.env.PG_USER}:${process.env.PG_PASS}@${process.env.PG_HOST}:${process.env.PG_PORT}/${process.env.PG_DATABASE}`;

const conn = new Pool({ 
  connectionString: connectionString,
  ssl: { rejectUnauthorized: false }
});

module.exports = conn;

//index.js

const express = require('express');
const app = express();
const pool = require("./db"); //stores super secret db info
const cors = require("cors");

const PORT = process.env.PORT || 5500;

app.use(cors());
app.use(express.json()); // => req.body
app.use(express.static('public'));

app.get("/apiv1/:tier", async (req, res) => {
    try {
        const { date, tier } = req.params;
        const allData = await pool.query(
            "SELECT * FROM previous WHERE tier=$1 ORDER BY DESC LIMIT 25;", 
            [tier]
            );
        const results = allData.rows;
        console.log(results)
        // const output = { "data": Object.fromEntries(
        //     results.map(
        //         item => [item.pokemon, item]
        //         ))
        //     };
        // res.json(output);
    } catch (error) {
        console.log(error.message);
    };
});

app.listen(PORT, () => {
    console.log(`Server running on port ${PORT}.`);
});

我的凭据有效，并且我的登陆页面已加载，但当我尝试转到

localhost:5500/apiv1/anything

时，我在控制台中收到错误页面和消息

The server does not support SSL connections

，但我已采取步骤允许 SSL 连接。

Answer 1

您的本地 postgreSQL 服务器似乎未启用 ssl。

在

db.js

中删除 ssl 选项，它应该可以工作：

const conn = new Pool({ 
  connectionString: connectionString,
  // ssl: { rejectUnauthorized: false } // remove this line
});

Answer 2

在你的 postgres uri 中使用

sslmode=disable

postgresql://user:pwd@localhost:5432/db?schema=public&sslmode=disable
