Question

我对boto自动化相对较新，并创建了一个脚本，使用python的boto API在AWS上设置自动缩放基础架构。

但是，我无法将我的VPC与我的负载均衡器创建相关联。以下代码返回格式错误的输入错误：

zoneStrings = 'eu-west-1a', 'eu-west-1b' #The availability zones of my VPC
elb_conn = boto.ec2.elb.connect_to_region('eu-west-1') #

lb_name = 'my-lb'
zones = zoneStrings
subnets = 'subnet-09519f50', 'subnet-9fa12dfa' #VPC subnets
ports= [(80, 80, 'http'), (443, 443, 'tcp')]
lb = elb_conn.create_load_balancer(lb_name, zones, subnets, ports)

完整错误是：

  Traceback (most recent call last):
  File "./test.py", line 70, in <module>
    lb = elb_conn.create_load_balancer(lb_name, zones, subnets, ports)
  File "/usr/local/lib/python2.7/dist-packages/boto/ec2/elb/__init__.py", line 243, in create_load_balancer
    params, LoadBalancer)
  File "/usr/local/lib/python2.7/dist-packages/boto/connection.py", line 1207, in get_object
    raise self.ResponseError(response.status, response.reason, body)
boto.exception.BotoServerError: BotoServerError: 400 Bad Request
<ErrorResponse xmlns="http://elasticloadbalancing.amazonaws.com/doc/2012-06-01/">

  </Error>
  <RequestId>12659703-a021-11e4-9488-1f8ceceab6a1</RequestId>
</ErrorResponse>

非常感谢任何见解。

boto文档指出create_load_balancer方法的参数顺序为：

名称
区
听众
子网
...

您似乎以不同的顺序提供它们。也许最安全的方法是使用关键字参数而不是依赖于位置顺序。所以：

lb = elb_conn.create_load_balancer(name=lb_name, zones=zones, subnets=subnets, listeners=ports)

这对你有用吗？
