我正在尝试使用 AWS CLI 在我的 CI 服务中的 CloudFront 上创建失效，以在部署时自动使文件失效。但是，CLI 返回一条成功消息，但引用的失效是一个月前的，并且没有创建新的失效。
我正在安装并启用云端:
pip install awscli
aws configure set preview.cloudfront true
aws configure set preview.create-invalidation true
然后我创建失效:
aws cloudfront create-invalidation --cli-input-json '{"DistributionId":"ABC123ABC123","InvalidationBatch":{"Paths":{"Quantity":1,"Items":["/index.html"]},"CallerReference":"codeship"}}'
响应示例，当我在美国东部时间 7 月 13 日下午 4 点运行此命令时:
{
"Invalidation": {
"Status": "Completed",
"InvalidationBatch": {
"Paths": {
"Items": [
"/index.html"
],
"Quantity": 1
},
"CallerReference": "codeship"
},
"Id": "1234567890",
"CreateTime": "2015-06-12T18:39:56.360Z"
},
"Location": "https://cloudfront.amazonaws.com/2015-04-17/distribution/ABC123ABC123/invalidation/1234567890"
}
当我登录到 CloudFront 时，我可以看到 6 月 12 日的一个失效，但昨天运行此命令时什么也没有。
我做错了什么吗？这个 CLI API 还能用吗？
最佳答案
看起来您在每次调用 CreateInvalidation 时都传递了相同的 CallerReference？ CallerReference 唯一标识特定的失效请求，因此 CloudFront 会为您提供使用该 CallerReference 的第一次失效的结果。来自documentation :
A value that you specify to uniquely identify an invalidation request. CloudFront uses the value to prevent you from accidentally resubmitting an identical request. Whenever you create a new invalidation request, you must specify a new value for CallerReference and change other values in the request as applicable. One way to ensure that the value of CallerReference is unique is to use a timestamp, for example, 20120301090000.
If you make a second invalidation request with the same value for CallerReference, and if the rest of the request is the same, CloudFront doesn't create a new invalidation request. Instead, CloudFront returns information about the invalidation request that you previously created with the same CallerReference.
If CallerReference is a value you already sent in a previous invalidation batch request but the content of any Path is different from the original request, CloudFront returns an InvalidationBatchAlreadyExists error.
