如何格式化 URL 以从 Amazon S3 获取文件？
我在弄清楚如何从 Amazon S3 访问文件时遇到一些问题。假设文件所在的存储桶是 BUCKET_NAME，文件是 FILE_NAME 等。我尝试了以下两个 URL：
https://s3.amazonaws.com/BUCKET_NAME/FILE_NAME/
?Expires=EXPIRATION
&Signature=SIGNATURE
&SignatureVersion=2
&SignatureMethod=HmacSHA1
&AWSAccessKeyId=KEYID
但这给了我以下错误：
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
我也尝试过：
https://s3.amazonaws.com/BUCKET_NAME/
?Key=FILE_NAME
&Expires=EXPIRATION
&Signature=SIGNATURE
&SignatureVersion=2
&SignatureMethod=HmacSHA1
&AWSAccessKeyId=KEYID
但这会返回一个网页，其中包含给定存储桶中的所有文件（包括 FILE_NAME），而不是我想要的特定文件。我也尝试将 Action=GetObject 放入 URL 中，但这似乎没有改变任何东西。
找出哪种方法（如果有）是正确的方法以及我做错了什么会很有帮助。我已经研究亚马逊的文档有一段时间了，但我似乎无法整理出来。
I am having some trouble figuring out how to access a file from Amazon S3. Lets say that the bucket that the file lives in is BUCKET_NAME, the file is FILE_NAME, etc. I have tried the following two URLs:
https://s3.amazonaws.com/BUCKET_NAME/FILE_NAME/
?Expires=EXPIRATION
&Signature=SIGNATURE
&SignatureVersion=2
&SignatureMethod=HmacSHA1
&AWSAccessKeyId=KEYID
But this gives me the following error:
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
I have also tried:
https://s3.amazonaws.com/BUCKET_NAME/
?Key=FILE_NAME
&Expires=EXPIRATION
&Signature=SIGNATURE
&SignatureVersion=2
&SignatureMethod=HmacSHA1
&AWSAccessKeyId=KEYID
but this returns a webpage with a list of all of the files in the given bucket (including FILE_NAME), instead of the specific file I want. I have also tried throwing in Action=GetObject into the URL as well but that doesn't seem to change anything.
It would be helpful to find out which (if any) is the proper method and what I am doing wrong. I have been digging through Amazon's documentation for a while now but I can't seem to sort it out.

URL 格式
公共访问 URL 示例
https://store-files-in-s3.s3.ap-south-1.amazonaws.com/image-Fri+Mar+08+2024+17%3A45%3A07+GMT%2B0530+（印度+标准+Time).png
在上面的示例中键入：
image-Fri Mar 08 2024 17:45:07 GMT+0530（印度标准时间）.pngFormat of the Url
Example of public access URL
https://store-files-in-s3.s3.ap-south-1.amazonaws.com/image-Fri+Mar+08+2024+17%3A45%3A07+GMT%2B0530+(India+Standard+Time).png
Key in above example:
image-Fri Mar 08 2024 17:45:07 GMT+0530 (India Standard Time).png也许不是 OP 所追求的，但对于那些搜索 URL 以简单地访问 S3 上的可读对象的人来说，更像是：
https://.amazonaws.com//< ;key> 其中
s3-ap-southeast-2。单击 S3 GUI 中的项目以获取您的存储桶的链接。
Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:
https://<region>.amazonaws.com/<bucket-name>/<key>Where
<region>is something likes3-ap-southeast-2.Click on the item in the S3 GUI to get the link for your bucket.
正如 @stevebot 所说，执行以下操作：
https://.s3.amazonaws.com/ 我想补充的一件重要的事情是，您要么使您的存储桶对象可公开访问，或者您可以将自定义策略添加到您的存储桶策略中。该自定义策略可能允许来自您的网络 IP 范围或不同凭据的流量。
As @stevebot said, do this:
https://<bucket-name>.s3.amazonaws.com/<key>The one important thing I would like to add is that you either have to make your bucket objects all publicly accessible OR you can add a custom policy to your bucket policy. That custom policy could allow traffic from your network IP range or a different credential.
请注意，如果您位于不同的 AWS 分区，例如美国 GovCloud 或中国，那么您的 URL 模式将略有不同。
https://.s3-.amazonaws.com/ 适用于 GovCloud。中国类似于
https://.s3-.amazonaws.com.cn/ 。Note that if you're in a different AWS partition, such as US GovCloud or China then you'll have a slightly different URL pattern.
https://<bucket-name>.s3-<region-name>.amazonaws.com/<key>works for GovCloud.China is something like
https://<bucket-name>.s3-<region-name>.amazonaws.com.cn/<key>.日期是 08.03.23，当前格式化 url 的方法是这样的：
The date is 08.03.23 and the current way to format the url is this:
它实际上的表述更像是：
请参阅此处
Its actually formulated more like:
See here
文档此处，我将使用法兰克福地区作为例子。
有 2 种不同的 URL 样式：
但此网址不起作用：
该消息是明确的：
您尝试访问的存储桶必须使用指定的终端节点进行寻址。请将未来的所有请求发送到此端点。我可能正在谈论另一个问题，因为我没有收到
NoSuchKey错误，但我怀疑随着时间的推移，错误消息已变得更加清晰。Documentation here, and I'll use the Frankfurt region as an example.
There are 2 different URL styles:
But this url does not work:
The message is explicit:
The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.I may be talking about another problem because I'm not getting
NoSuchKeyerror but I suspect the error message has been made clearer over time.
