从警告消息中我发现的内容有据可查here.

它说，将 server、replset 和 mongos 键的设置移动到对象的顶层.

// The options inside the `server` attributes are moved to its parents.
// Same happens to `replset` and `mongos`
// Change this
mongoose.connect( 'mongodb://localhost/db',
  {
    useMongoClient: true,
    server: {
      poolSize: 2
    },
    promiseLibrary: global.Promise
  }
);

// To this
mongoose.connect( 'mongodb://localhost/db',
  {
    useMongoClient: true,
    poolSize: 2,
    promiseLibrary: global.Promise
  }
);
