azure cosmos db在mongodb.com中创建了集合

Question

当我使用均值堆栈练习一些基本的crud操作时，我创建了一个名为“test”的数据库，并在“视频”集合中，后来我开始学习Cosmos DB，在那里创建了数据库“cosmos-db-demo”，并将集合创建为“视频集合”。我能够将我的应用程序连接到 cosmos DB，但我惊讶地发现，当我执行后操作时，数据入到测试中

mongoose.connect（'mongodb：//cosmos-db-acc：[e-mail]:10255/?ssl=true

Answer 1

关于这个问题，我们不能在应用程序中定义数据库名和连接名来告诉应用程序连接哪个数据库和连接。关于如何实现它，请在您的连接字符串中添加db名称，并添加< code>{ collection:"

例如

< li >创建<代码>。环境文件

COSMODDB_USER = "<Azure Cosmos account's user name, usually the database account name>"
COSMOSDB_PASSWORD = "<Azure Cosmos account password, this is one of the keys specified in your account>"
COSMOSDB_HOST= "<Azure Cosmos Host name>"
COSMOSDB_PORT=10255

var mongoose = require("mongoose");
var env = require("dotenv").config();

//connect
mongoose
  .connect(
    "mongodb://" +
      process.env.COSMOSDB_HOST +
      ":" +
      process.env.COSMOSDB_PORT +
      "/" +
      "User" + //  tell the application to connect which databse
      "?ssl=true&replicaSet=globaldb",
    {
      auth: {
        user: process.env.COSMODDB_USER,
        password: process.env.COSMOSDB_PASSWORD,
      },
      useNewUrlParser: true,
      useUnifiedTopology: true,
      retryWrites: false,
    },
  )
  .then(() => console.log("Connection to CosmosDB successful"))
  .catch((err) => console.error(err));

// define model
const Family = mongoose.model(
  "Family",
  new mongoose.Schema(
    {
      lastName: String,
      parents: [
        {
          familyName: String,
          firstName: String,
          gender: String,
        },
      ],
      children: [
        {
          familyName: String,
          firstName: String,
          gender: String,
          grade: Number,
        },
      ],
      pets: [
        {
          givenName: String,
        },
      ],
      address: {
        country: String,
        state: String,
        city: String,
      },
    },
    { collection: "Familay" }, // tell the application to connect which connection
  ),
);

const family = new Family({
  lastName: "Volum",
  parents: [{ firstName: "Thomas" }, { firstName: "Mary Kay" }],
  children: [
    { firstName: "Ryan", gender: "male", grade: 8 },
    { firstName: "Patrick", gender: "male", grade: 7 },
  ],
  pets: [{ givenName: "Buddy" }],
  address: { country: "USA", state: "WA", city: "Seattle" },
});

family.save((err, saveFamily) => {
  console.log(JSON.stringify(saveFamily));
});
