Question

我正在尝试创建一个带有aws-sdk的课程，我得到：

 Service must be constructed with `new` operator

以下是代码：

Class AWS {
    // constructor omitted 

    connect({client='ecs'}={})
        {
          let config =
            {
              accessKeyId: this.aws_access_key,
              secretAccessKey: this.aws_secret_key,
              region: this.region
            };

          try {
            switch (client) {
              case 'dynamodb': conn = aws.DYNAMODB(config); break;
              case 'ec2':      conn = aws.EC2(config);      break;
              case 'ecs':      conn = aws.ECS(config);      break;
              case 'elb':      conn = aws.ELBv2(config);    break;
            }
            return conn;
          }
          catch(err)
          {
            console.log(err.message);
          }
        }
}

以下是我如何称呼它......

var a = new AWS(
    {
      cluster: 'my-cluster',
      environment: 'dev',
      project: 'proj1',
      region: 'us-east-2',
      service: 'api-feed-validation'
    });
a.connect({client:'ecs'})

我不知道自己错过了什么......

new

应该是：

switch

这当然假设你所谓的某个地方：

conn = aws.DYNAMODB(config)

NodeJS：服务必须使用`new`运算符构造
