无法在 AWS Dynamodb 上运行示例代码。
我正在尝试运行他们在该网站上提供的 AWS 示例 python 代码。这是我的 python 文件:
from __future__ import print_function # Python 2/3 compatibility
import boto3
dynamodb = boto3.resource('dynamodb', region_name='us-west-2', endpoint_url="http://localhost:8000")
table = dynamodb.create_table(
TableName='Movies',
KeySchema=[
{
'AttributeName': 'year',
'KeyType': 'HASH' #Partition key
},
{
'AttributeName': 'title',
'KeyType': 'RANGE' #Sort key
}
],
AttributeDefinitions=[
{
'AttributeName': 'year',
'AttributeType': 'N'
},
{
'AttributeName': 'title',
'AttributeType': 'S'
},
],
ProvisionedThroughput={
'ReadCapacityUnits': 10,
'WriteCapacityUnits': 10
}
)
print("Table status:", table.table_status)
然后我在终端中运行 python 文件，出现以下错误:
File "MoviesCreateTable.py", line 32, in <module>
'WriteCapacityUnits': 10

请您参考如下方法:
当 Dynamodb 未运行时会发生这种情况。检查 localhost:8000/shell 以验证它正在运行。
确保所有 prerequisites满足文档中给出的条件。
Before you begin this tutorial, you need to do the following:
- Download and run DynamoDB on your computer. For more information, see Download and Run DynamoDB.
- Sign up for Amazon Web Services and create access keys. You need these credentials to use AWS SDKs. To create an AWS account, go to http://aws.amazon.com/, choose Create an AWS Account, and then follow the online instructions.
- Create an AWS credentials file. For more information, see Configuration in the Boto 3 documentation.
- Install Python 2.6 or later. For more information, see https://www.python.org/downloads.
