我只是从我的数据库创建一个名为 Fruits 的数据库app.js，并使用 Mongoose 将数据库连接到 MongoDB。

const mongoose = require("mongoose");

mongoose.connect("mongodb://localhost:27017/fruitsDB", {useNewUrlParser: true});

mongoose.set('strictQuery', false);

const fruitSchema = new mongoose.Schema({
    name: String,
    rating: Number,
    review: String
});

const Fruit = mongoose.model("Fruit", fruitSchema);

const fruit = new Fruit({
    name: "Apple",
    rating: 7,
    review: "Taste Good"
});

fruit.save();

每当我尝试时node app.js，我都会收到DeprecationWarning。尽管我尝试使用mongoose.set('strictQuery', true);，但同样的错误仍然存​​在，如下所示：

(node:15848) [MONGOOSE] DeprecationWarning: Mongoose: the `strictQuery` option w

ictQuery', false);` …
