amazon-web-services - 当源是 S3 存储桶时，AWS CloudFront 返回 http 307

Question

我已经用一些文件创建了 s3 存储桶。我使用该 S3 存储桶作为源创建了 CloudFront 分配，并将状态更改为已部署。

当我为任何文件 curl CloudFront 时，我得到:

<Error><Code>TemporaryRedirect</Code><Message>Please re-send this request to the specified temporary endpoint. Continue to use the original request endpoint for future requests.</Message><Bucket>MY-BUCKET</Bucket><Endpoint>MY-BUCKET.s3-eu-west-1.amazonaws.com</Endpoint><RequestId>...</RequestId><HostId>...</HostId></Error>

当我为任何文件 curl 我的 S3 存储桶时，我会得到该文件内容。

我究竟做错了什么？如何强制 cloudfront 缓存文件，以便客户端不需要直接从 S3 获取数据？

Thx Matt Houser 从评论到我的第一篇文章!

当分发尚未完全准备好时，CloudFront 似乎缓存了我对文件的第一个请求(但当时它处于部署状态，所以要小心!)。我请求使缓存中的所有文件失效，这需要几分钟，但在失效完成后，所有文件都使用 CloudFront url 用 http 200 curl 。

在 Michael-sqlbot 发表评论后，问题变得清晰起来:

All buckets have at least two REST endpoint hostnames. In eu-west-1, they are example-bucket.s3-eu-west-1.amazonaws.com and example-bucket.s3.amazonaws.com. The first one will be immediately valid when the bucket is created. The second one -- sometimes referred to as the "global endpoint" -- which is the one CloudFront uses -- will not, unless the bucket is in us-east-1. Over a period of seconds to minutes, variable by location and other factors, it becomes globally accessible as well. Before that, the 307 redirect is returned. Hence, the bucket was not ready.
