推荐答案

下面的（基于以上问题的答案，我发现上的 http://www.ec2studio.com/articles/s3.html ）：

Here's what worked for me with the AWS SDK and MVC 3 (based on the answers above and what I found on http://www.ec2studio.com/articles/s3.html):

public ActionResult GetS3Object(string bucket, string key)
{
    string accessKeyID = ConfigurationManager.AppSettings["AWSAccessKey"];
    string secretAccessKeyID = ConfigurationManager.AppSettings["AWSSecretKey"];
    using (AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID))
        {
        GetPreSignedUrlRequest request = new GetPreSignedUrlRequest()
            .WithBucketName(bucket)
            .WithKey(key)
            .WithExpires(DateTime.Now.Add(new TimeSpan(7, 0, 0, 0)));
        return Redirect(client.GetPreSignedURL(request));
        }
}
