测试从具有发送/接收消息权限到队列但未收到消息的 Cloud9 角色发送 SQS 消息

Question

I was using Cloud9 to assume a role to test on the dynamic permission to send message to a queue.

In cloud9, i assumed this role with the following permissions

{
"Version": "2012-10-17",
"Statement": [
    {
        "Sid": "VisualEditor0",
        "Effect": "Allow",
        "Action": [
            "sqs:DeleteMessage",
            "sqs:ReceiveMessage",
            "sqs:SendMessage",
            "sqs:GetQueueAttributes"
        ],
        "Resource": [
            "arn:aws:sqs:us-west-2:{accountID}:general-queue-abc",
            "arn:aws:sqs:eu-west-2:{accountID}:individual-queue-${insert-attribute-by-customer-name}"
        ]
    },
    {
        "Sid": "VisualEditor1",
        "Effect": "Allow",
        "Action": "sqs:ListQueues",
        "Resource": "*"
    }
]

}

After assuming and verifying the right role was assumed, i use cli to send message to the queue, it succeeded with the output

{
"MD5OfMessageBody": "dummyNumbers",
"MessageId": "dummyNumbers" }

Expected: SQS to show as 1 message received since the message sent request succeeded.

What I saw instead - Number Of Messages Sent increased but no Number Of Messages Received

But the queue shows message available

My command

aws sqs send-message --queue-url https://sqs.{REGION}.amazonaws.com/{AccountID}/individual-queue-{insert-attribute-by-customer-name} --message-body "I am sending a new message...."

Question:

• I thought my action was to send a message to SQS queue from Cloud9 after assuming the right permission access, and the queue was supposed to have 'Number of Message Received' since the queue-url i specified the message to send to is the same queue. I am confused with why no 'number of message received' when there's message available shown.
• there is no cloudwatch logs that are able to help me to understand anything
• does this means that the permission actually allows the message sent but there is some issue in the queue receiving the message? (For example access denied?)

thanks in advance

Answer 1

Sounds like you have sent 2 messages but haven't received (ie read from the queue) any. Try running the following to receive a message:

aws sqs receive-message --queue-url https://sqs.{REGION}.amazonaws.com/{AccountID}/individual-queue-{insert-attribute-by-customer-name}
