Python 解析boto3输出JSON

Python 解析boto3输出JSON,python,json,amazon-web-services,boto3,amazon-iam,Python,Json,Amazon Web Services,Boto3,Amazon Iam,我正在使用此代码获取IAM用户: #!/usr/bin/env python import boto3 import json client = boto3.client('iam') response = client.list_users( ) print response 并获得: {u'Users': [{u'UserName': 'ja', u'Path': '/', u'CreateDate': datetime

我正在使用此代码获取IAM用户:

    #!/usr/bin/env python


    import boto3
    import json


    client = boto3.client('iam')

    response = client.list_users(

    )

    print response
并获得:

{u'Users': [{u'UserName': 'ja', u'Path': '/', u'CreateDate': datetime.datetime(2018, 4, 6, 12, 41, 18, tzinfo=tzutc()), u'UserId': 'AIDAJXIHXCSI62ZQKLGZM', u'Arn': 'arn:aws:iam::233135199200:user/ja'}, {u'UserName': 'test', u'Path': '/', u'CreateDate': datetime.datetime(2018, 4, 7, 10, 55, 58, tzinfo=tzutc()), u'UserId': 'AIDAIENHQD6YWMX3A45TY', u'Arn': 'arn:aws:iam::233135199200:user/test'}], 'ResponseMetadata': {'RetryAttempts': 0, 'HTTPStatusCode': 200, 'RequestId': 'ebd600f0-3a52-11e8-bc50-d37153ae8ac5', 'HTTPHeaders': {'x-amzn-requestid': 'ebd600f0-3a52-11e8-bc50-d37153ae8ac5', 'date': 'Sat, 07 Apr 2018 11:00:44 GMT', 'content-length': '785', 'content-type': 'text/xml'}}, u'IsTruncated': False}
我保存了对JSON文件的响应

我只需要提取用户名,这样在这种情况下输出应该是2行:

ja
test
添加时

print response['Users'][0]['UserName']

仅获取名字,如果设置为
[]
,则语法不正确

无需转换为JSON。响应作为Python对象返回:

import boto3
client = boto3.client('iam')
response = client.list_users()

print ([user['UserName'] for user in response['Users']])
这将导致:

['ja', 'test']
或者,您可以使用:

for user in response['Users']:
  print (user['UserName'])
这导致:

ja
test

谢谢约翰,同时我找到了解决办法:
#/usr/bin/env python import boto3 import json client=boto3.client('iam')response=client.list_用户()范围内的i(0,len(response['users')):打印响应['users'][i]['UserName']
您还可以使用:
aws iam列表用户——查询用户[*]。UserName
