Amazon and redirects

[tmikaeld]

When I used an EU region for Amazon, it did a 301 redirect response which was followed automatically in Deno but since you only accept 200 response, I'm not sure if it should be a setting or not?

Can you give me some more details? Which method are you using - getObject ? Is this an authenticated or unauthenticated request? What configuration of the bucket is resulting in a redirect? (this?) Is it redirecting to another key in the same bucket, or to an external URL?

I think it's a little involved to handle this situation, as if it's an external URL it doesn't make sense to treat it as an Amazon request. But if it's redirecting to another key on the same bucket, a whole new request has to be generated and signed; presumably simply getting the new URL won't work without authentication.

Sorry, I should have sent an example from the start.

import { S3Client } from "https://deno.land/x/[email protected]/mod.ts";

// Connecting to a local MinIO server:
const s3client = new S3Client({
  endPoint: "s3.amazonaws.com",
  region: "eu-central-1",
  accessKey: "secret",
  secretKey: "Secret",
  bucket: "test",
  pathStyle: true,
});

await s3client.getObject("test.txt");

Gives:

error: Uncaught (in promise) Error: Unexpected response code from the server (expected 200, got 301 Moved Permanently).
        throw new errors.ServerError(
              ^
    at Client.makeRequest (https://deno.land/x/[email protected]/client.ts:270:15)
    at async Client.getPartialObject (https://deno.land/x/[email protected]/client.ts:388:12)
    at async file:///home/tests/server.ts:14:1

The redirect URL is just the same URL, so not sure why it's even replying with 301...

Ah @tmikaeld I see now. I believe you just need to change the endPoint setting to s3.eu-central-1.amazonaws.com and then it won't be redirecting you.

You are correct sir, now it works! Thanks 👍
