Node 和 MongoDB - 插入文档


要在数据库集合中插入文档,可以使用collection.insertOne()collection.insertMany()方法插入一个或多个文档。

database.collection("sampleCollection").insertOne(firstDocument, function(error, res) {
   if (error) throw error;
   console.log("1 document inserted");
});
database.collection("sampleCollection").insertMany(documents, function(error, res) {
   if (error) throw error;
   console.log("Documents inserted: " + res.insertedCount);
});

例子

尝试以下示例在 mongodb 集合中插入文档 -

将以下示例复制并粘贴为 mongodb_example.js -

const MongoClient = require('mongodb').MongoClient;
// Prepare URL
const url = "mongodb://localhost:27017/";
const firstDocument = {
   First_Name : 'Mahesh',
   Last_Name : 'Parashar',
   Date_Of_Birth: '1990-08-21',
   e_mail: 'mahesh_parashar.123@gmail.com',
   phone: '9034343345'
};
const documents = [{
   First_Name : 'Radhika',
   Last_Name : 'Sharma',
   Date_Of_Birth: '1995-09-26',
   e_mail: 'radhika_sharma.123@gmail.com',
   phone: '9000012345'
},
{
   First_Name : 'Rachel',
   Last_Name : 'Christopher',
   Date_Of_Birth: '1990-02-16',
   e_mail: 'rachel_christopher.123@gmail.com',
   phone: '9000054321'
},
{
   First_Name : 'Fathima',
   Last_Name : 'Sheik',
   Date_Of_Birth: '1990-02-16',
   e_mail: 'fathima_sheik.123@gmail.com',
   phone: '9000012345'
}
];
// make a connection to the database
MongoClient.connect(url, function(error, client) {
   if (error) throw error;
   console.log("Connected!");
   // Connect to the database
   const database = client.db('myDb');
   database.collection("sampleCollection").insertOne(firstDocument, function(error, res) {
      if (error) throw error;
      console.log("1 document inserted");
   });
   database.collection("sampleCollection").insertMany(documents, function(error, res) {
      if (error) throw error;
      console.log("Documents inserted: " + res.insertedCount);
   }); 
   // close the connection
   client.close();
});

输出

使用 Node 执行 mysql_example.js 脚本并验证输出。

node mongodb_example.js
Documents inserted: 3
1 document inserted
