我的代码有问题,我在其中使用了此代码应用程序.js:

const mongoose = require('mongoose'); 
const dotenv = require('dotenv');
dotenv.config()

mongoose.connect(process.env.MONGO_URL)
.then(() => console.log("DB connected!"));

mongoose.connection.on('error',function(err){
console.log("The error is: ");
});

env.txt:

MONGO_URL=mongodb+srv://blur:blur@nodeapi-pfnvf8.mongodb.net/test?retryWrites=true
PORT:8080

由于某种原因,它给了我这个奇怪的错误:

throw new MongooseError('The `uri` parameter to `openUri()` must be a ' +
^ MongooseError: The `uri` parameter to `openUri()` must be a string, got "undefined". Make sure the first parameter to `mongoose.connect()` or `mongoose.createConnection()` is a string.

有人可以帮我吗我读了一些帖子,但没有一个有帮助

最佳答案

当您未将 .env 文件保存在根文件夹中时,也会发生这种情况。
