Making requests using the REST API - Amazon Simple Storage Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Making requests using the REST API

This section contains information on how to make requests to Amazon S3 endpoints by using the REST API. For a list of Amazon S3 endpoints, see Regions and Endpoints in the Amazon General Reference.

Constructing S3 hostnames for REST API requests

Amazon S3 endpoints follow the structure shown below:

s3.Region.amazonaws.com.cn

Amazon S3 access points endpoints and dual-stack endpoints also follow the standard structure:

  • Amazon S3 access pointss3-accesspoint.Region.amazonaws.com.cn

  • Dual-stacks3.dualstack.Region.amazonaws.com.cn

For a complete list of Amazon S3 Regions and endpoints, see Amazon S3 endpoints and quotas in the Amazon Web Services General Reference.

Virtual hosted‐style and path‐style requests

When making requests by using the REST API, you can use virtual hosted–style or path-style URIs for the Amazon S3 endpoints. For more information, see Virtual hosting of buckets.

Example Virtual hosted–Style request

Following is an example of a virtual hosted–style request to delete the puppy.jpg file from the bucket named examplebucket in the US West (Oregon) Region. For more information about virtual hosted-style requests, see Virtual-hosted–style requests.

DELETE /puppy.jpg HTTP/1.1 Host: examplebucket.s3.us-west-2.amazonaws.com.cn Date: Mon, 11 Apr 2016 12:00:00 GMT x-amz-date: Mon, 11 Apr 2016 12:00:00 GMT Authorization: authorization string

Example Path-style request

Following is an example of a path-style version of the same request.

DELETE /examplebucket/puppy.jpg HTTP/1.1 Host: s3.us-west-2.amazonaws.com.cn Date: Mon, 11 Apr 2016 12:00:00 GMT x-amz-date: Mon, 11 Apr 2016 12:00:00 GMT Authorization: authorization string

Currently, Amazon S3 supports both virtual-hosted–style and path-style URL access in all Amazon Web Services Regions. However, path-style URLs will be discontinued in the future. For more information, see the following Important note.

For more information about path-style requests, see Path-style requests.

Important

Update (September 23, 2020) – To make sure that customers have the time that they need to transition to virtual-hosted–style URLs, we have decided to delay the deprecation of path-style URLs. For more information, see Amazon S3 Path Deprecation Plan – The Rest of the Story in the Amazon News Blog.

Making requests to dual-stack endpoints by using the REST API

When using the REST API, you can directly access a dual-stack endpoint by using a virtual hosted–style or a path style endpoint name (URI). All Amazon S3 dual-stack endpoint names include the region in the name. Unlike the standard IPv4-only endpoints, both virtual hosted–style and a path-style endpoints use region-specific endpoint names.

Example Virtual hosted–Style dual-stack endpoint request

You can use a virtual hosted–style endpoint in your REST request as shown in the following example that retrieves the puppy.jpg object from the bucket named examplebucket in the US West (Oregon) Region.

GET /puppy.jpg HTTP/1.1 Host: examplebucket.s3.dualstack.us-west-2.amazonaws.com.cn Date: Mon, 11 Apr 2016 12:00:00 GMT x-amz-date: Mon, 11 Apr 2016 12:00:00 GMT Authorization: authorization string

Example Path-style dual-stack endpoint request

Or you can use a path-style endpoint in your request as shown in the following example.

GET /examplebucket/puppy.jpg HTTP/1.1 Host: s3.dualstack.us-west-2.amazonaws.com.cn Date: Mon, 11 Apr 2016 12:00:00 GMT x-amz-date: Mon, 11 Apr 2016 12:00:00 GMT Authorization: authorization string
