获取未使用的负载均衡器列表

Question

我正在尝试列出未使用的负载均衡器（elb）。我正在尝试以下代码，并且会引发错误

'属性错误'：'str'对象没有属性'describe_instance_health（）'

import boto3

elb = boto3.client('elb')

allElbs = elb.describe_load_balancers()
print (allElbs)
for lb in allElbs:
    instances = lb.describe_instance_health()
    if len(instances)==0:
        print (lb)
    for instanceState in instances:
        if  instanceState.state == 'OutOfService':
            print (lb)

请帮助我解决这个问题。谢谢

Answer 1

以下。调用describe_load_balancers()将返回一个字典。在字典中，您可以找到磅的列表。参见here和here。

import boto3

elb = boto3.client('elb')

allElbs = elb.describe_load_balancers()
print (allElbs)
for lb in allElbs['LoadBalancerDescriptions']:
    instances = elb.describe_instance_health(lb['LoadBalancerName'])
    if len(instances)==0:
        print (lb)
    for instanceState in instances:
        if  instanceState.state == 'OutOfService':
            print (lb)
