如何通过名称访问MongoDB数据库；mongodb://127.0.0.1/testDatabase"

我想知道如何设置mongoDB数据库，以便我可以使用以下名称访问它：mongodb://127.0.0.1/testDatabase“

我什么也没找到，因为我不知道它的主题

谢谢

你能提供更多细节吗？您尝试访问MongoDB的方式和位置？是否要设置新的MongoDB数据库并连接到它？

  Connect to Mongodb Instance:
  In the following example, the URI connection string specifies connecting to a 
  MongoDB instance that is running on localhost using port 27017. 
  The myproject indicates the database to use. 
  If the database is omitted, the MongoClient uses the default test database:


  var MongoClient = require('mongodb').MongoClient
  , assert = require('assert');

 // Connection URL
 var url = 'mongodb://localhost:27017/myproject';

// Use connect method to connect to the server
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
console.log("Connected successfully to server");

db.close();
});
