Other SDKs

If AWS S3 officially doesn't support the language you're using, you can adopt the following strategies to integrate with RustFS:

1. Direct HTTP Interface Requests (Based on S3 API Protocol)

The S3 protocol is a standard RESTful API. You can encapsulate access logic yourself using any language that supports HTTP requests (such as C, Rust, Lua, Erlang).

Key points include

• Signature Algorithm: Implement AWS Signature Version 4 signing (complex)
• Construct Correct Headers and Canonical Requests
• Use HTTPS/HTTP clients to send requests

👉 Recommend referring to signature implementations from open source projects, for example:

• https://docs.aws.amazon.com/general/latest/gr/sigv4-signed-request-examples.html

2. Call CLI Tools or Intermediate Services from Existing SDKs

If you don't want to implement signing yourself, you can:

2.1. Use AWS CLI tools supported by existing languages

For example, call through Shell:

aws s3 cp local.txt s3://mybucket/myfile.txt --endpoint-url http://rustfs.local:9000

Or write a simple relay service using Node.js/Python SDK, and your language calls this service for upload/download.

2.2. Set up a Proxy (e.g., Flask, FastAPI, Express)

Let clients that don't support S3 call your wrapped HTTP API:

POST /upload -> Service internally calls SDK to upload objects to RustFS
GET /presigned-url -> Generate presigned URLs for frontend/client use

3. Look for Third-Party Community SDKs

Although AWS doesn't have official SDKs, some language communities have developed unofficial S3 clients. For example:

• Haskell: amazonka-s3
• Rust: rusoto (deprecated) or aws-sdk-rust
• OCaml: Possibly implement through cohttp
• Delphi: Commercial libraries supporting S3 protocol

Community SDK stability varies greatly; evaluate activity, documentation, and compatibility before use.

4. Delegate Core Upload Logic to Platform Hosting

For example:

• Delegate frontend (Web/Mobile) upload tasks to browser or app execution (using presigned URLs)
• Backend uses Node.js/Python/Go proxy to implement upload logic

Summary Recommendations

Scenario	Recommended Solution
Need full control/embedded environment	Implement Signature V4 self-signing
Weak language support but has Shell	Call uploads through AWS CLI
Can deploy relay service	Build S3 API gateway using Python/Node
Frontend uploads	Use presigned URLs
