Upload data to DO Spaces using a TCP connection

Posted March 26, 2019 1.4k views

I was hoping to find out there was any way to upload data to DigitalOcean Spaces using a TCP connection. I am currently getting a 302 Found error when I attempt to connect to my Spaces using a TCP connection.

Greetings!

TCP traffic should be fine. The 302 code is a redirect. I suspect you may be connecting over http rather than https. Make sure the URL you’re connecting to is https. If that is the case and you’re still seeing this, let us know the full error you’re getting from your application, as well as more information about what you are using to connect, and we may have more insight.

Thank you. We are using https. We have been able to connect using TCP but we get the 302 code error when we try to upload a data file. Should we still be using the AWS3 protocols when attempting to upload data using TCP? Is there a way to check data logs for Spaces? Perhaps those logs have some additional details on what we are doing wrong.

    The 302 code isn’t so much an error but is actually an http redirect. It’s interesting that you’re seeing this with the https call. We are mostly compatible with S3 protocol, but not fully 1:1 compatible (just mostly). You can read more about that here:

    https://developers.digitalocean.com/documentation/spaces/

    I tried to look up some information on espressif but didn’t get far as to how that correlates. If you can provide more about the function/call or the full underlying request being made to our API from it, that may open up more insight.

      When we run the following code through Postman

      PUT /example2.txt HTTP/1.1
      Host: SPACESID.sfo2.digitaloceanspaces.com
      Content-Type: text/plain
      Host: SPACES      ID.sfo2.digitaloceanspaces.com

      We get the following error back after 2 minutes or so when we use the following http request:

        Interesting. I assume the SPACES_ID is a replacement for privacy, given the public space. It might be a good idea to run this by our support team so that they can pass back to you their findings from logs on our side, just to make sure this is covered. Of course, anyone else in our community is welcome to weigh in if they’ve dealt with this, but I’d love for you to get the answer.

        You can open a ticket with our team here:
        https://cloudsupport.digitalocean.com/s/

        They are a bit backed up right now, but working to handle the tickets as quickly as possible.

In case it is helpful, we are trying to upload data files using Espressif
