亚马逊S3上传与公共权限 [英] Amazon S3 upload with public permissions

问题描述

我使用的是亚马逊的C＃SDK，并试图要上传的文件，但默认情况下它已受限制的权限。我想予以公布，但我似乎无法找出如何做到这一点作为上载部分。

我斗是公开的，但是当我上传新文件中使用下面的code，我上传的文件是不公开的。

有没有人面前做到这一点？

 公共类S3Uploader
{
    私人字符串awsAccessKeyId;
    私人字符串awsSecretAccessKey;
    私人字符串bucketName;
    私人Amazon.S3.Transfer.TransferUtility transferUtility;

    公共S3Uploader（字符串bucketName）
    {
        this.bucketName = bucketName;
        this.transferUtility =新Amazon.S3.Transfer.TransferUtility（XXXXXXXXXXXXXXXXXX，XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX）;

    }

    公共无效UploadFile（字符串文件路径，字符串toPath）
    {
        AsyncCallback的回调=新的AsyncCallback（uploadComplete）;
        transferUtility.BeginUpload（文件路径，bucketName，toPath，回调，空）;
    }

    私人无效uploadComplete（IAsyncResult的结果）
    {
        VAR X =结果;
    }
}
 

解决方案

找到了，需要使用 TransferUtilityUploadRequest ：

 公共类S3Uploader
{
    私人字符串awsAccessKeyId;
    私人字符串awsSecretAccessKey;
    私人字符串bucketName;
    私人Amazon.S3.Transfer.TransferUtility transferUtility;

    公共S3Uploader（字符串bucketName）
    {
        this.bucketName = bucketName;
        this.transferUtility =新Amazon.S3.Transfer.TransferUtility（XXXXXXXXXXXXXXXXXX，XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX）;

    }

    公共无效UploadFile（字符串文件路径，字符串toPath）
    {
        AsyncCallback的回调=新的AsyncCallback（uploadComplete）;
        VAR uploadRequest =新TransferUtilityUploadRequest（）;
        uploadRequest.FilePath =文件路径;
        uploadRequest.BucketName =my_s3_bucket;
        uploadRequest.Key = toPath;
        uploadRequest.AddHeader（X-AMZ-ACL，大众阅读）;
        transferUtility.BeginUpload（uploadRequest，回调，空）;
    }

    私人无效uploadComplete（IAsyncResult的结果）
    {
        VAR X =结果;
    }
}
 

I'm using the Amazon C# SDK and trying to upload a file, but by default it has restricted permissions. I would like to make it publicly available, but I can't seem to find out how to do it as part of the upload.

My bucket is public, but when I upload a new file using the code below, the file I upload is not public.

Has anyone had to do this before?

public class S3Uploader
{
    private string awsAccessKeyId;
    private string awsSecretAccessKey;
    private string bucketName;
    private Amazon.S3.Transfer.TransferUtility transferUtility;

    public S3Uploader(string bucketName)
    {
        this.bucketName = bucketName;
        this.transferUtility = new Amazon.S3.Transfer.TransferUtility("XXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");

    }

    public void UploadFile(string filePath, string toPath)
    {
        AsyncCallback callback = new AsyncCallback(uploadComplete);
        transferUtility.BeginUpload(filePath, bucketName, toPath, callback, null);
    }

    private void uploadComplete(IAsyncResult result)
    { 
        var x = result;
    }
}

解决方案

Found it, need to use a TransferUtilityUploadRequest:

public class S3Uploader
{
    private string awsAccessKeyId;
    private string awsSecretAccessKey;
    private string bucketName;
    private Amazon.S3.Transfer.TransferUtility transferUtility;

    public S3Uploader(string bucketName)
    {
        this.bucketName = bucketName;
        this.transferUtility = new Amazon.S3.Transfer.TransferUtility("XXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX");

    }

    public void UploadFile(string filePath, string toPath)
    {
        AsyncCallback callback = new AsyncCallback(uploadComplete);
        var uploadRequest = new TransferUtilityUploadRequest();
        uploadRequest.FilePath = filePath;
        uploadRequest.BucketName = "my_s3_bucket";
        uploadRequest.Key = toPath;
        uploadRequest.AddHeader("x-amz-acl", "public-read");
        transferUtility.BeginUpload(uploadRequest, callback, null);
    }

    private void uploadComplete(IAsyncResult result)
    { 
        var x = result;
    }
}
