Question

我正在尝试由邮递员向S3发出发布请求，但我收到了response code 403 - Forbidden。 CORS和政策是权利，我使用预先签名的网址：

url = _client.generate_presigned_post(Bucket=_BUCKET_NAME, Key=key,
    Fields={'acl': 'public-read', 'Content-Type': 'image/jpeg'},
    Conditions=[
        {'acl': 'public-read'},
        {'success_action_status': "201"},
        ['starts-with', '$key', ''],
        ['content-length-range', 0, 100000],
        {'x-amz-algorithm': 'AWS4-HMAC-SHA256'},
        {'Content-Type': 'image/jpg'}
       ],
    ExpiresIn=expiration)

邮递员的回复：

<?xml version="1.0" encoding="UTF-8"?>
<Error>
    <Code>AccessDenied</Code>
    <Message>Request has expired</Message>
    <Expires>1970-01-05T04:00:00Z</Expires>
    <ServerTime>2019-06-11T12:40:50Z</ServerTime>
    <RequestId>xxxxxxxxxxx</RequestId>
    <HostId>xxxxxxxxxxxxx</HostId>
</Error>

我的问题出在水桶的政策上。我修复了将Resource更改为"arn:aws:s3:::mi-stagging"的{{1}}

将发布请求过期至S3
