如何使用AWS SDK for ASP.NET将文件上载到特定文件夹？ – 我能够通过指定存储桶名称(request.WithBucketName)来上传文件,但我希望能够将文件上传到存储桶本身的特定文件夹.
public bool UploadFileToS3(string uploadAsFileName,Stream ImageStream,S3CannedACL filePermission,S3StorageClass storageType,string toWhichBucketName)
{
try
{
client = Amazon.AWSClientFactory.CreateAmazonS3Client(MY_AWS_ACCESS_KEY_ID,MY_AWS_SECRET_KEY);
PutObjectRequest request = new PutObjectRequest();
request.WithKey(uploadAsFileName);
request.WithInputStream(ImageStream);
request.WithBucketName(toWhichBucketName);
request.CannedACL = filePermission;
request.StorageClass = storageType;
client.PutObject(request);
client.Dispose();
}
catch
{
return false;
}
return true;
}
希望这段代码能帮到你.
解决方法
要将文件添加到存储桶中的文件夹,您需要更新PutObjectRequest的Key以在文件名前包含该文件夹.
public bool UploadFileToS3(string uploadAsFileName,string toWhichBucketName)
{
try
{
using(client = Amazon.AWSClientFactory.CreateAmazonS3Client(MY_AWS_ACCESS_KEY_ID,MY_AWS_SECRET_KEY))
{
PutObjectRequest request = new PutObjectRequest();
request.WithKey( "folder" + "/" + uploadAsFileName );
request.WithInputStream(ImageStream);
request.WithBucketName(toWhichBucketName);
request.CannedACL = filePermission;
request.StorageClass = storageType;
client.PutObject(request);
}
}
catch
{
return false;
}
return true;
}
This post讨论将文件上传到文件夹.他们正在使用TransferUtilityUploadRequest,但它应该与PutObjectRequest一起使用.滚动到相关示例的底部.
This post显示了如何在不向其上传文件的情况下创建文件夹.
希望这有用
