[英]MongooseError: The `uri` parameter to `openUri()` must be a string, got "undefined"
我是 mongo 的新手,我尝试建立连接,但我收到一个我不知道如何解决的错误,错误如下:
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. did not connect
(node:21807) [MONGOOSE] DeprecationWarning: Mongoose: the `strictQuery` option will be switched back to `false` by default in Mongoose 7. Use `mongoose.set('strictQuery', false);` if you want to prepare for this change. Or use `mongoose.set('strictQuery', true);` to suppress this warning.
(Use `node --trace-deprecation ...` to show where the warning was created)
我的代码如下:
索引.js
/* MONGOOSE SETUP */
const PORT = process.env.PORT || 6001;
mongoose
.connect(process.env.MONGO_URL, {
useNewUrlParser: true,
useUnifiedTopology: true,
})
.then(() => {
app.listen(PORT, () => console.log(`Server Port: ${PORT}`));
})
.catch((error) => console.log(`${error} did not connect`));
.env 文件
MONGO_URL= 'mongodb+srv://User:Password@cluster0.is8ykod.mongodb.net/?retryWrites=true&w=majority'
PORT = 3001
我认为 MONGO_URL 不像字符串,但我不明白为什么,我已经尝试使用:
require('dotenv').config();
但收到此错误:
ReferenceError: require is not defined in ES module scope, you can use import instead
This file is being treated as an ES module because it has a '.js' file extension and '/Users/gianlca/Desktop/progetto/server/package.json' contains "type": "module". To treat it as a CommonJS script, rename it to use the '.cjs' file extension.
我不能像'.cjs'一样重命名它因为我在文件中的导入它们也开始不起作用
确保您在 URI 上指定了数据库名称。
URI 应该是:
mongodb+srv://User:Password@cluster0.is8ykod.mongodb.net/yourDataBaseName?retryWrites=true&w=majority
