如何修复：“MongoError：身份验证失败”@MongoDB Atlas答案

【问题标题】：how to fix: 'MongoError: authentication fail' @MongoDB Atlas如何修复：“MongoError：身份验证失败”@MongoDB Atlas
【发布时间】：2019-09-16 20:58:19
【问题描述】：

我正在连接到 MongoDB Atlas 并收到身份验证失败错误。

这是我的连接字符串：

mongodb://user:<password>@mongo-cluster-shard-00-00-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-01-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-02-ixqtu.mongodb.net:27017/test?ssl=true&replicaSet=mongo-cluster-shard-0&authSource=admin&retryWrites=true

这就是我得到的：

【问题讨论】：

用你自己设计的用户名和密码替换

标签： node.js mongodb mongoose keystonejs

【解决方案1】：

您必须将user 和password 放入您的连接URI 字符串中

 mongodb://***'your user':' here comes password '***@mongo-cluster-shard-00-00-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-01-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-02-ixqtu.mongodb.net:27017/test?ssl=true&replicaSet=mongo-cluster-shard-0&authSource=admin&retryWrites=true

例如

 mongodb://dbuser:dbpassword@mongo-cluster-shard-00-00-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-01-ixqtu.mongodb.net:27017,mongo-cluster-shard-00-02-ixqtu.mongodb.net:27017/test?ssl=true&replicaSet=mongo-cluster-shard-0&authSource=admin&retryWrites=true

【讨论】：

当我在连接字符串中使用我的凭据时出现此错误消息
插入你的 user 和 password 没有单引号 ' ' 我更新了它检查 @evil-cat

【解决方案2】：

问题是我将留在了连接字符串中。您必须删除它们才能进行身份验证。

【讨论】：

我已建议您同样检查我的答案，如果您的问题已解决，请将其标记为答案

【解决方案3】：

我在连接到新的 Atlas 数据库时遇到了类似的错误。即使我已经按照此处和文档中的说明正确设置了用户名和密码（显然我用正确的 MLAB 密码替换了 PASSWORD：

var mongoURI = 'mongodb+srv://heroku_3kcdl3j9:PASSWORD@cluster-3kcdl3j9.auof1.mongodb.net/heroku_3kcdl3j9?retryWrites=true&w=majority';

我已将我的数据库从 MLAB 迁移到 Atlas，成功地将正确的网络访问设置设置为 0.0.0.0 IP 地址。在 Heroku 中设置环境变量。但还是会出现这个错误：

【讨论】：

我也有同样的问题。我有多个组件，在 Google Kubernetes 上运行，都使用相同的环境变量连接到 MongoDB Atlas M10 数据库（从 mLab 迁移）。所有组件都连接成功，除了一个抛出 MongoError: Authentication failed 的组件。你知道如何解决这个问题吗？
我也有同样的问题。即使我复制并粘贴 URL，一个应用程序也无法连接另一个应用程序。

【解决方案4】：

我也遇到过这个问题。但一个小时后，我知道我使用了 process.env 变量作为用户名和密码。并且还在 .env 文件中声明了它们。但是我忘记在我的代码中配置 dotenv 包了。

所以请确保你没有犯这种愚蠢的错误。

【解决方案5】：

我遇到了类似的错误，就我而言，问题是我在“安全 -> 网络访问”页面的“IP 访问列表”中添加（列入白名单）错误的 IP 地址。
