If you're using Swarm without the Gateway proxy, you must add the "--post301 --location-trusted" curl options. You do not need to pass user credentials with Swarm.

If you need to write an unnamed object you must input the file via stdin and use " |
This also works, but unless you're using "-T" curl will load the entire file into memory.

InfoYou can specify multiple files, but remember these files will use the Gateway spool directory. |
...
The URL is only the bucket (or a subdirectory-like path), the object name will be based on the filename uploaded. |
This type of upload will result in objects that are either a single object (replicated as policy.replicas) or EC (see Working with Large Objects) depending on factors such as the file size and EC settings. Whether a file is uploaded with Transfer-encoding: chunked can also influence how it's written.
SCSP

Multipart (
...
Parallel Write)
This is useful for uploading large files. You "initiate" the upload, then upload each part of the file , then and make a "complete" request. See Multipart Write Example.
This type of upload always results in an EC object, even if the final object is smaller than the EC minimum setting.
S3
...
Multipart Upload
The S3 protocol is only supported via Gateway but the implementation of S3 multipart uses Swarm SCSP multipart (parallel writes) and behaves similarly. The s3cmd utility provides a good way to do a multipart upload, but rclone is faster because it uploads the parts in parallel. If your bucket allows "anonymous" writes, you can use "curl".
