Question

我尝试使用aws文档中的基本示例，通过如下启动dynamoDB。 java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb

它产生输出 Initializing DynamoDB Local with the following configuration: Port: 8000 InMemory: false DbPath: null SharedDb: true shouldDelayTransientStatuses: false CorsParams: *

示例python代码如下。

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)

但是我得到了输出：

Traceback (most recent call last):
  File "test.py", line 32, in <module>
    'WriteCapacityUnits': 10
  File "/home/janga/anaconda2/lib/python2.7/site-packages/boto3/resources/factory.py", line 520, in do_action
    response = action(self, *args, **kwargs)
  File "/home/janga/anaconda2/lib/python2.7/site-packages/boto3/resources/action.py", line 83, in __call__
    response = getattr(parent.meta.client, operation_name)(**params)
  File "/home/janga/.local/lib/python2.7/site-packages/botocore/client.py", line 251, in _api_call
    return self._make_api_call(operation_name, kwargs)
  File "/home/janga/.local/lib/python2.7/site-packages/botocore/client.py", line 537, in _make_api_call
    raise ClientError(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (503) when calling the CreateTable operation (reached max retries: 9): <HTML><TITLE>503 Service Unavailable</TITLE>
<H1>503 Service Unavailable</H1>
Failed to connect to server <B>localhost</B></HTML>

我无法在任何地方找到解决此问题的方法。我能想到的唯一原因是，我在一个在代理服务器后面运行的大学网络上。但我找不到任何解决办法。请帮忙。
