Mongoose 身份验证错误：命令查找需要身份验证。但我做到了

Question

我正在尝试查找我知道存在的文档，因为我可以在管理控制台中看到它，这要归功于 mongo-express... 但是当我使用 Model.findOne( 时，它会吐出以下错误消息。我究竟做错了什么？ （主机名 'mongo' 是我的 docker 容器，它连接得很好，我可以在日志中看到它）

这是我的代码：

// This all works because the following events show success, and no error.
// So I know it's authing correctly on initial connection
-dbConnect.js-
"user strict"

import mongoose from "mongoose"

const connection = mongoose.createConnection( 
"mongodb://mongo:27017/dbName?authSource=admin", {
              useNewUrlParser: true,
              user: process.env.user,
              pass: process.env.pass,
              keepAlive: true,
            })
connection.on( "connected", () => {
  console.log( "MONGOOSE: connected" )  
})

connection.on( "close", () => {
  console.log( "MONGOOSE: connection close" )  
})

connection.on( "error", error => {
  console.log( "MONGOOSE: connection error", error )  
})

export default connection

-

-models/auth.js-
"use strict"

import mongoose from "mongoose"
import connection from "../dbConnect"

const xSchema = new mongoose.Schema(
  {
    id    : String,
    user  : String,
    pass  : String
  },
  { collection: "x" }
)
export const X = connection.model( "X", xSchema )

-

-controllers/auth.js-
import { X } from "../models/auth"
//Promise wrapper
X.findOne( { id: incommingId }, ( error, x ) => {
  //handler
})

我最终得到了这个错误

MongoError: command find requires authentication

Answer 1

答案简单而愚蠢。上面的一切都是正确的......留下未定义的环境变量。

显然 mongo 可以让您在未经授权的情况下进行连接，您无能为力。正确填充这些环境变量，一切都完美地移动了。
