Linux - NodeJS、Express、PostgreSQL - 錯誤處理程序：用戶“root”的密碼驗證失敗

Question

編輯 -

成功！ 看來我應該有RTFM 。 使用環境變量似乎需要與手冊完全一致。

固定代碼：

# PostgreSQL Database Infomation
PGDATABASE_TEST = user_db
PGDATABASE = user_db
PGUSER = postgres
PGPASSWORD = password

# PostgreSQL Host and Port Infomation
PGHOST = localhost
PGPORT = 5432

我正在使用.env變量連接到 Postgres 數據庫。

通過 Postman 向 Express API 提交數據時，我收到一條錯誤消息，說明如下：

            throw new ErrorHandler(error.statusCode, error.message)
                  ^

ErrorHandler: password authentication failed for user "tito"
    at UserService.createUserAccount (/home/tito/Documents/GitHub/***/server/services/user.service.js:11:19)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)
    at async createUserAccount (/home/tito/Documents/GitHub/***/server/controllers/user.controller.js:11:18) {
  status: 'error',
  statusCode: undefined
}

如您所見，它使用我的操作系統用戶名而不是.env設置一個。 使用sudo運行節點時，出現root的身份驗證錯誤。

我的db.js ：

require("dotenv").config();
const { Pool } = require("pg");

// Check which Database to use. Live is safe.
const isProduction = process.env.NODE_ENV === 'PRODUCTION';
const database = process.env.NODE_ENV === 'TEST' ? process.env.PG_TEST_DATABASE : process.env.PG_DATABASE;

// Request to Database contructed
const connectionString = `postgresql://${process.env.PG_USER}:${process.env.PG_PASS}@${process.env.PG_HOST}:${process.env.PG_PORT}/${database}`;

// Setup Pool. 
const pool = new Pool ({
    connectionString: isProduction ? process.env.DATABASE_URL : connectionString,
    ssl: isProduction ? { rejectUnauthorized: false } : false
});

console.log(`Ready at : ${connectionString}`)

module.exports = {
    query: (text, params) => pool.query(text, params),
    end: () => pool.end()
}

我的.env ：

# Express API Port.
PORT = 5000

# Enviroment - TEST for local. PRODUCTION for live.
NODE_ENV = PRODUCTION

# PostgreSQL Database Infomation
PG_TEST_DATABASE = user_db
PG_DATABASE = user_db
PG_USER = postgres
PG_PASS = password

# PostgreSQL Host and Port Infomation
PG_HOST = localhost
PG_PORT = 5432

我的UserService ：

const {
    createUserAccount_DB
} = require("../db/user.db");
const { ErrorHandler } = require("../helpers/error")

class UserService {
    createUserAccount = async (user) => {
        try {
            return await createUserAccount_DB(user);
        } catch (error) {
            throw new ErrorHandler(error.statusCode, error.message)
        }
    }
}

module.exports = new UserService();

我的createUserAccount ：

const userService = require("../services/user.service");
const { ErrorHandler } = require("../helpers/error");

const createUserAccount = async (req, res) => {

    console.log("Create Account API Triggered");

    const { user_name, user_pass, user_email } = req.body;
    // const hashedPassword = hashedPassword(password);
     
    const user = await userService.createUserAccount({
        user_name,
        user_pass,
        user_email
    });

    res.status(201).json({
        status: "success",
        user,
    })
};
