我正试图获得的价值VersionLabel是php-v1,但我的代码不能正常工作,我不知道我做错了什么.

你能不能让我知道什么是错的,我怎么解析php-v1？

这是我的错误消息.

TypeError: the JSON object must be str, not 'dict'

这是我的代码.

#!/usr/bin/env python3

import boto3
import json

def get_label():
   try:
      env_name = 'my-env'
      eb = boto3.client('elasticbeanstalk')
      response = eb.describe_instances_health(
         EnvironmentName=env_name,
         AttributeNames=[
            'Deployment'
         ]
      )
      #print(response)
      data = json.loads(response)
      print(data['VersionLabel'])
   except:
      raise

if __name__ == '__main__':
   get_label()

这是我在print(response)调用AWS时得到的响应.

如何删除Route 53中的DNS记录？我按照文档,但我仍然无法使其工作.我不知道我在这里遗失了什么.

根据文档:

DELETE:删除具有Name,Type,SetIdentifier(用于延迟,加权,地理位置和故障转移资源记录集)和TTL(别名资源记录集除外)的现有资源记录集,其中TTL由您要将DNS查询路由到的AWS资源.

但我总是得到这个错误:

我正在使用asyncioPython 模块，但我不知道我的简单代码有什么问题。它不会异步执行任务。

#!/usr/bin/env python3    

import asyncio
import string    


async def print_num():
    for x in range(0, 10):
        print('Number: {}'.format(x))
        await asyncio.sleep(1)    

    print('print_num is finished!')    

async def print_alp():
    my_list = string.ascii_uppercase    

    for x in my_list:
        print('Letter: {}'.format(x))
        await asyncio.sleep(1)    

    print('print_alp is finished!')    


async def msg(my_msg):
    print(my_msg)
    await asyncio.sleep(1)    


async def main():
    await msg('Hello World!')
    await print_alp()
    await msg('Hello Again!')
    await print_num()    


if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())
    loop.close()

这是调用脚本时的输出：

Hello World!
Letter: A
Letter: B

我正在使用AWS的Boto3编写一个Python脚本来管理安全组.我创建了一个字典来获取组ID及其属性.我可以访问属性,sg-aaaaaaaa但当我试图访问时sg-bbbbbbbb,它总是抛出一个KeyError.

我是如何创建字典的

def get_rules(sg_ids, region):
    sg_rules = {}
    sg_rules['SecurityGroups'] = []
    ec2 = boto3.client('ec2', region_name=region)

    for sg_id in sg_ids:
        response = ec2.describe_security_groups(
            Filters=[
                {
                    'Name': 'group-id',
                    'Values': [
                        sg_id
                    ]
                }
            ]
        )
        data = response['SecurityGroups'][0]['IpPermissions']

        sg_rules['SecurityGroups'].append({sg_id: data})

    return sg_rules
