当我连接到 mongo atlas 时会发生此错误，但是当我使用本地数据库时它工作正常。查看数据库连接图像和终端错误以获取更多信息。

数据库连接.ts

import mongoose from "mongoose";

export default async function dbConnect() {

    if (mongoose.connection.readyState >= 1) {
        return;
    }

    return mongoose.connect(process.env.MONGO_URL as string, {
        useNewUrlParser: true,
        useUnifiedTopology: true,
        useFindAndModify: false,
        useCreateIndex: true,
    });
}

这是我在下面遇到的错误

您可以在console.log(process.env.MONGO_URL)内部检查function dbConnect()以查看它是否未定义。

这是因为我对同样的错误消息有同样的问题

MongoError：身份验证失败

我dotenv在app.js文件中需要，但是当应用程序启动时，它将以bin/www文件开头。所以我把下面的代码放在bin/www文件中。

// Config
require('dotenv').config({
  path: './config/keys.env'
})

在dbConnection.js文件中，

// Connecting database
module.exports.connectDB = async () => {
  try {
    await mongoose
      .connect(process.env.MONGODB_URL, {
        useNewUrlParser: true,
        useUnifiedTopology: true,
        useFindAndModify: false,
        useCreateIndex: true,
      })
      .then(() => console.log("MongoDB connected..."));
  } catch (err) {
    console.error(err);
  }
};

令人惊讶的是，在那之后一切对我来说都很好。

所以你应该先检查。如果未定义，则表示您的env文件在bdConnect()执行后处理。
