这是我的代码：

const mongoose = require('mongoose');

const connectDB = async () => {
    const conn = await mongoose.connect(process.env.MONGO_URI,
        {
            useNewUrlParser: true,
            useCreateIndex: true,
            useFindAndModify: false,
            useUnifiedTopology: true
        });
    console.log(`MongoDB Connected: ${conn.connection.host}`);
};

module.exports = connectDB;
