使用AWS CLI上传到S3时如何设置Content-Type? [英] How do I set Content-Type when uploading to S3 with AWS CLI?

问题描述

我正在尝试设置S3静态网站托管，但似乎在我的任何未在AWS控制台中设置Content-Type元数据字段的对象上返回403.我无法弄清楚如何使用AWS CLI工具执行此操作.

I'm trying to set up S3 static website hosting, but it appears to return 403 on any of my objects that don't have the Content-Type metadata field set in the AWS console. I cannot figure out how to do this with the AWS CLI tool.

使用--metadata选项似乎有效:

$ aws s3api put-object --bucket <bucket> --key foo.html --body foo.html --metadata Content-Type=text/html
{
    "ETag": "\"fd5ff7743e5ed1e1c304eb1c34e8e39f\""
}
$ aws s3api head-object --bucket <bucket> --key foo.html
{
    "AcceptRanges": "bytes",
    "ContentType": "binary/octet-stream",
    "LastModified": "Wed, 15 Apr 2015 06:39:48 GMT",
    "ContentLength": 189,
    "ETag": "\"fd5ff7743e5ed1e1c304eb1c34e8e39f\"",
    "Metadata": {
        "content-type": "text/html"
    }
}

但是该对象上的Content-Type字段在AWS控制台的元数据"部分中不可见，并且尝试在浏览器中访问文件时得到403.

But the Content-Type field on the object isn't visible in the "Metadata" section of the AWS console, and I get a 403 when trying to access the file in a browser.

使用--content-type选项也不起作用:

$ aws s3api put-object --bucket <bucket> --key foo.html --body foo.html --content-type text/html
{
    "ETag": "\"fd5ff7743e5ed1e1c304eb1c34e8e39f\""
}
$ aws s3api head-object --bucket <bucket> --key foo.html
{
    "AcceptRanges": "bytes",
    "ContentType": "text/html",
    "LastModified": "Wed, 15 Apr 2015 06:46:49 GMT",
    "ContentLength": 189,
    "ETag": "\"fd5ff7743e5ed1e1c304eb1c34e8e39f\"",
    "Metadata": {}
}

虽然似乎设置了某种特殊的ContentType属性，但AWS控制台中仍然没有Content-Type元数据字段，我也无法在浏览器中访问文件.

While it appears to set some sort of special ContentType property, there still isn't a Content-Type metadata field in the AWS console, nor can I access the file in a browser.

我也尝试过类似的命令(aws s3 cp，aws s3 sync)，但是没有运气.我已将存储桶策略设置为公开可读.

I've also tried similar commands (aws s3 cp, aws s3 sync), with no luck. I have the bucket policy set to publicly-readable.

推荐答案

第二个使用--content-type的示例是设置对象内容类型的方法.显示的JSON响应正在将HTTP响应中的Content-Type标头映射到ContentType键，但是它对应于对象的实际Content-Type标头.我确认使用--content-type时，控制台的元数据部分中确实显示了内容类型值.

Your second example with --content-type is the way to set content type for an object. The JSON response displayed is mapping the Content-Type header in the HTTP response to the ContentType key, but it corresponds to the actual Content-Type header of the object. I confirmed that the content type value does show up in the metadata section in the console when using --content-type.

$ aws s3api put-object --bucket bucket --key foo.json --body foo.json --content-type application/json --acl public-read

$ aws s3api head-object --bucket jamesls-test-sync --key foo.json
{
    "AcceptRanges": "bytes",
    "ContentType": "application/json",
    "LastModified": "Wed, 15 Apr 2015 17:18:58 GMT",
    "ContentLength": 0,
    "ETag": "\"d41d8cd98f00b204e9800998ecf8427e\"",
    "Metadata": {}
}

还使用curl，我们可以看到设置了内容类型标头:

Also using curl, we can see the content type header is set:

$ curl -I https://bucket.s3.amazonaws.com/foo.json
HTTP/1.1 200 OK
