AWS DynamoDB Python连接错误

Question

无法在AWS Dynamodb上运行示例代码。

我想运行他们在那里提供的AWS示例python代码网站。这里是我的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) 

我然后我运行终端蟒蛇文件，我得到以下错误：

这发生在Dynamodb没有运行。检查localhost:8000/shell以验证它正在运行。

确保文档中给出的所有prerequisites都满足。

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 .
