AWS CLI中的地图数据类型

问题描述

我正在尝试添加一条消息以在亚马逊AWS sqs中排队

i am trying to add a message to queue in amazon aws sqs

所以我尝试了这个

root~#  aws sqs send-message --queue-url "queue/url" --message-body "message with attribute" --message-attributes '{"Name": "somename", "Type":"String", "Value":"somevalue"}'

它给了我这个错误

'unicode' object has no attribute 'keys'

但是如果我从命令中删除了--message-attributes部分

but if i remove the --message-attributes part from the command

 root~#  aws sqs send-message --queue-url "queue/url" --message-body "message with attribute"

然后完美运行

http://docs.aws.amazon. com/cli/latest/reference/sqs/send-message.html

我想这是地图类型，如何以地图格式发送此参数

i guess that it is map type how can send this parameter in map format

--message-attributes (map)

推荐答案

您需要传递--message-attributes (map)数据结构，如{attr1 : {"DataType":"type1.option", "StringValue":val1}, attr2 : {"DataType":"typ2.option", "StringValue":val2}, ...}

You need to pass --message-attributes (map) data structre like {attr1 : {"DataType":"type1.option", "StringValue":val1}, attr2 : {"DataType":"typ2.option", "StringValue":val2}, ...}

因此您的示例如下:

$ aws sqs send-message --queue-url "queue/url"  --message-body "message with attribute" --message-attributes '{"somename" : { "DataType":"String", "StringValue":"somevalue"}}'
{
    "MD5OfMessageBody": "ZZZZ",
    "MD5OfMessageAttributes": "YYYY",
    "MessageId": "06524772-XXXX"
}

接收队列

$ aws sqs receive-message --queue-url "queue/url" --message-attribute-names somename
{
    "Messages": [
        {
            "Body": "message with attribute",
            "ReceiptHandle": "dummy==",
            "MD5OfBody": "ZZZZ",
            "MD5OfMessageAttributes": "YYYYS",
            "MessageId": "06524772-XXXX",
            "MessageAttributes": {
                "somename": {
                    "DataType": "String",
                    "StringValue": "somevalue"
                }
            }
        }
    ]
}
