Uploading objects with presigned URLs - Amazon Simple Storage Service
AWSDocumentationAmazon Simple Storage Service (S3)User Guide


UPLOADING OBJECTS WITH PRESIGNED URLS

PDFRSS



You may use presigned URLs to allow someone to upload an object to your Amazon
S3 bucket. Using a presigned URL will allow an upload without requiring another
party to have AWS security credentials or permissions. A presigned URL is
limited by the permissions of the user who creates it. That is, if you receive a
presigned URL to upload an object, you can upload an object only if the creator
of the URL has the necessary permissions to upload that object.

When someone uses the URL to upload an object, Amazon S3 creates the object in
the specified bucket. If an object with the same key that is specified in the
presigned URL already exists in the bucket, Amazon S3 replaces the existing
object with the uploaded object. After upload, the bucket owner will own the
object.

For general information about presigned URLs, see Working with presigned URLs.

You can create a presigned URL for uploading an object without writing any code
by using AWS Explorer for Visual Studio. You can also generate a presigned URL
programmatically by using the AWS SDKs.

If you're using Visual Studio, you can generate a presigned URL without writing
any code by using AWS Explorer in the AWS Toolkit for Visual Studio. For more
information, see Using Amazon S3 from AWS Explorer in the AWS Toolkit for Visual
Studio User Guide.

For instructions on installing AWS Explorer, see Installing and setting up the
AWS Toolkit for Visual Studio in the AWS Toolkit for Visual Studio User Guide.

 1. Choose a bucket in the Amazon S3 view and open the context menu
    (right-click).

 2. Choose Create presigned URL, and then set the expiration date and time.

 3. Choose PUT to specify that this presigned URL will be used for uploading an
    object.

 4. Choose the Generate button.

 5. To copy the URL to the clipboard, choose Copy.

 6. To use this URL you can send a PUT request with the curl command. Include
    the path to your file you specified when creating your URL and the presigned
    URL itself.
    
    curl -X PUT -T "/path/to/file" "presigned URL"
    
    


USING AWS EXPLORER FOR VISUAL STUDIO

If you're using Visual Studio, you can generate a presigned URL without writing
any code by using AWS Explorer in the AWS Toolkit for Visual Studio. For more
information, see Using Amazon S3 from AWS Explorer in the AWS Toolkit for Visual
Studio User Guide.

 1. Choose a bucket in the Amazon S3 view and open the context menu
    (right-click).

 2. Choose Create presigned URL, and then set the expiration date and time.

 3. Choose PUT to specify that this presigned URL will be used for uploading an

 4. Choose the Generate button.

 5. To copy the URL to the clipboard, choose Copy.

 6. To use this URL you can send a PUT request with the curl command. Include
    the path to your file you specified when creating your URL and the presigned
    URL itself.
    
    curl -X PUT -T "/path/to/file" "presigned URL"
    
    

For examples of using the AWS SDKs to generate a presigned URL for uploading an
object, see Create a presigned URL for Amazon S3 by using an AWS SDK.

When you use the AWS SDKs to generate a presigned URL, the maximum expiration
time is 7 days from the time of creation.

NOTE

For all AWS Regions launched after March 20, 2019 you need to specify the
endpoint-url and AWS Region with the request. For a list of all the Amazon S3
Regions and endpoints, see Regions and Endpoints in the AWS General Reference.
