[英]aws-cli won't work with a variable I created in bash
I'm trying to write a bash script for creating an AWS SQS queue and then check that the queue is empty.我正在尝试编写一个 bash 脚本来创建 AWS SQS 队列,然后检查队列是否为空。 For that I created the following script that should return "null":
为此,我创建了以下应返回“null”的脚本:
aws sqs create-queue --queue-name MessagesQueue
queue_url=$(aws sqs list-queues --query QueueUrls[0])
queue_check=$(aws sqs get_queue_attributes --queue_url $queue_url --attribute-names ApproximateNumberOfMessages --query Attributes[0].ApproximateNumberOfMessages
And I receive this error message instead:我收到此错误消息:
An error occurred (InvalidAddress) when calling the GetQueueAttributes operation: The address "https://eu-west-3.queue.amazonaws.com/XXXXXXXXXXXX/MessagesQueue" is not valid for this endpoint.
But if I explicitly write the same address in the command instead of using $queue_url it works fine and returns 'null' as it should.但是,如果我在命令中明确写入相同的地址而不是使用 $queue_url 它工作正常并返回'null',因为它应该。
Why isn't it accepting $queue_url but accepts the same URL address if I explicitly write it?为什么它不接受 $queue_url 而是接受相同的 URL 地址,如果我明确写了它?
Edit : It seems like the aws-cli command reads the variable $queue_url
as the URL between single and double-quotes, and when I write it explicitly it reads the URL with no quotes so that's why it accepts it.编辑:似乎 aws-cli 命令读取变量
$queue_url
作为单引号和双引号之间的 URL,当我明确写入它时,它读取不带引号的 URL,这就是它接受它的原因。 How can I use the bash variable I created so the aws-cli reads it with no quotes?如何使用我创建的 bash 变量,以便 aws-cli 不带引号读取它?
Once I tried to run your code, part by part (started with aws sqs list_queues ), I have noticed:一旦我尝试逐步运行您的代码(从 aws sqs list_queues 开始),我注意到:
aws: error: argument operation: Invalid choice, valid choices are:
...
Invalid choice: 'list_queues', maybe you meant:
* list-queues
Try out list-queues instead list_queues and let know how it goes.尝试使用 list-queues 而不是 list_queues 并让我们知道它是如何进行的。
I solved it, I just had to remove the quotes from the output and I did it like this:我解决了它,我只需要从输出中删除引号,我是这样做的:
queue_url=$(aws sqs list-queues --query QueueUrls[0])
queue_url="${queue_url%\"}"
queue_url="${queue_url#\"}"
