MongoDB 用户 - 身份验证失败

Question

所以我想知道为什么我的所有 MongoDB 用户的身份验证都失败了。一切正常，直到我删除了一个用户，从那时起我的所有用户都被拒绝了。 我使用 Altas 并且我已将我的用户设置为 dbAdmin 并授予了所有权限，经过仔细检查，所以我在密码中没有打字错误，我设置了 IP 地址，确保我正确复制了 url 。 . 我正在尝试与 Nodejs 应用程序连接，这是我的代码：

const express = require("express");
const mongoose = require("mongoose");
const app = express();
// Connect to DB
const mongoURI =
    "mongodb+srv://MyUserName:<MyPassword>@cluster0.lbb8n.mongodb.net/<DbImUsing>?retryWrites=true&w=majority";
mongoose.connect(mongoURI, {
    useNewUrlParser: true,
    useUnifiedTopology: true,
});
// Route
app.set("view engine", "ejs");
app.get("/", (req, res) => {
    res.render("index");
});
// Endpoint
app.post("/shortUrls", (req, res) => {});
app.listen(process.env.PORT || 5000);

我收到的错误消息是：

Answer 1

尝试扩展连接

useNewUrlParser: true,
useCreateIndex: true,
useFindAndModify: false,
useUnifiedTopology: true,

还要检查您的 MongoDB 中的网络访问。

添加您当前的 IP 地址。

Answer 2

查看服务器日志以了解身份验证失败的原因。

如果您在免费或共享层 (m0/m2/m5)，日志不可用，您必须猜测。

由于您使用的是 SRV URI，请尝试明确指定身份验证源：

    "mongodb+srv://MyUserName:<MyPassword>@cluster0.lbb8n.mongodb.net/<DbImUsing>?retryWrites=true&w=majority&authSource=admin"
