python boto3参数验证错误 [英] python boto3 parameter validation error

问题描述

在这里，我编写了一个python程序来启动一个符合所有条件的实例.但是在执行程序时显示以下错误. botocore.exceptions.ParamValidationError:参数验证失败:参数InstanceIds的无效类型，值:i-012345678，类型:< type'str'> ;，有效类型:< type'list'> ;，< type'tuple'> .下面是我的代码:

Here I have written a python program to start an instance that matches all the conditions. But The following error is displayed while executing the program.botocore.exceptions.ParamValidationError: Parameter validation failed: Invalid type for parameter InstanceIds, value: i-012345678, type: <type 'str'>, valid types: <type 'list'>, <type 'tuple'> .Below is my code:

import boto3
ec2=boto3.client('ec2',region_name='ap-south-1')
a=ec2.describe_instances()
for i in a['Reservations']:
    for x in i['Instances']:
       if x['InstanceId']=="i-12345678" and x['State'['Name']=='stopped':
            n = x['InstanceId']
            ec2.start_instances(InstanceIds=n)`

推荐答案

错误本身是不言自明的.您必须传递实例ID的列表或元组，而不只是字符串.您可以在文档

The error itself is self-explanatory. You have to pass a list or tuple of instance ids rather than just string. You can see this in the docs

请参阅下面的更新代码.

See the updated code below.

import boto3
ec2=boto3.client('ec2',region_name='ap-south-1')
a=ec2.describe_instances()
for i in a['Reservations']:
    for x in i['Instances']:
       if x['InstanceId']=="i-12345678" and x['State'['Name']=='stopped':
            n = x['InstanceId']
            ec2.start_instances(InstanceIds=[n])`
