创建到期链接S3或托管的Cloudfront含量的ASP.NET(Creating expiring

任何人有创建使用ASP.NET的到期签署的URL的例子吗？ 我使用的是探索LitS3或ThreeSharp在我的项目，并没有看到任何具体的方法在任何这些项目的做到这一点。 谢谢。

Answer 1:

下面是与AWS SDK和MVC 3为我工作（基于以上问题的答案，我上找到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));
        }
}

Answer 2:

使用亚马逊的.NET SDK就可以得到preSignedUrl

using (AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client("your access key ID", "you secret key"))
            {
                GetPreSignedUrlRequest getPreSignedUrl = new GetPreSignedUrlRequest().WithBucketName(bucketName);
                getPreSignedUrl.Key = key;
                getPreSignedUrl.Expires = DateTime.Now.AddSeconds(60);
            }

Answer 3:

发现这个 （中提到的这个线程在AWS论坛）类库在Amazon S3中生成签署的网址。 如果任何人有任何其他建议/方法来尝试，让我知道。

编辑：ThreeSharp有我一直在寻找的功能。 从ThreeSharpConsoleSample应用：

      using (UrlGetRequest request = new UrlGetRequest("mytestbucket", "mytestfile.txt"))
            {
                request.ExpiresIn = 60 * 10000;
                using (UrlGetResponse response = service.UrlGet(request))
                {
                    Console.WriteLine("Try this url in your web browser (it will only work for 60 seconds)\n");
                    string url = response.StreamResponseToString();
                    Console.WriteLine(url);
                }
            }
            Console.WriteLine("\npress enter >");
            Console.ReadLine();
