Python AWS Boto3 SAML 身份验证错误

Question

您好，我正在尝试查找端口 22 0.0.0.0/0 打开的所有 AWS EC2 实例。我有下面的代码，但仍然遇到下面的身份验证处理错误。看来 boto 无法识别我已通过身份验证。我一直在四处寻找，但找不到如何处理此错误。关于如何处理以下错误有什么想法吗？

import sys
import boto
from boto import ec2
from boto import sns
import os
import boto3


# Call the saml API Key Retreiver - Must be stored in C:\Temp
os.system('"C:/Temp/apikeyretriever_windows_386.exe"')

# Set Profile to SAML
session = boto3.session.Session(profile_name='saml')



connection = ec2.connect_to_region("us-east-1")
connSNS = boto.sns.connect_to_region("us-east-1")
sg = connection.get_all_security_groups('us-east-1')

listOfInstances = ""
messages = "Following Instances have port 22 open"


def getTag(instanceId):
    reservations = connection.get_all_instances(filters={'instance_id': instanceId})
    for r in reservations:
        for i in r.instances:
            return i.tags['Name']


try:

    for securityGroup in sg:
        for rule in securityGroup.rules:

            global instanceId;

            if (rule.from_port == '22' and rule.to_port == '22') and '0.0.0.0/0' in str(rule.grants):
                for instanceid in securityGroup.instances():
                    listOfInstances += "Instance Name : " + getTag(instanceId.split(':')[
                                                                       1]) + "\t State:" + instanceid.state + "\t SecurityGroup:" + securityGroup.name + "\n"

                    connSNS.publish(topic='sns-arn-endpoint', message=messages + "\n" + listOfInstances,
                                    subject='ProjectName : Server List with Port 22 Open')

except:
    print('Some Error occurred : ')
    print
    sys.exc_info()
    connSNS.publish(topic='sns-arn-endpoint', message=sys.exc_info(), subject='script ended with error')

错误信息:

您从堆栈跟踪中收到的错误消息看起来像是您的脚本找不到 STS token ，我假设 apikeyretriever_windows_386.exe 应该为您创建和存储该 token ，以登录 API在您的 AWS 凭证/配置文件中名为“saml”的配置文件下。
