NeoFS HTTP Protocol Gateway

NeoFS HTTP Protocol Gateway bridges NeoFS internal protocol and HTTP standard.

  • you can download one file per request from NeoFS Network
  • you can upload one file per request into the NeoFS Network

Notable make targets

dep          Check and ensure dependencies
image        Build clean docker image
dirty-image  Build diry docker image with host-built binaries
fmts         Run all code formatters
lint         Run linters
version      Show current version

Install

go get -u github.com/nspcc-dev/neofs-http-gate

File uploading behaviors

  • you can upload on file per request
  • if FileName not provided by Header attributes, multipart/form filename will be used instead

Configuration
