Fixes after review
- It's confusing. If there is no difference, I suggest having the route named after the protocol verb or resulting handler. So it should be either post or upload.
- Don't you find that it would be more understandable without else ifs?
- Why do we need a temporary file here?
- etc

NeoFS HTTP Gate

NeoFS HTTP Gate is example of tool that provides basic interactions with NeoFS.

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

Notable make targets

  Usage:

    make <target>

  Targets:

    deps      Check and ensure dependencies
    dev       Build development docker images
    help      Show this help prompt
    image     Build docker image
    publish   Publish docker image
    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

# Flags

  -h, --help                       show help
  -v, --version                    show version
      --key string                 "generated" to generate key, path to private key file, hex string or wif (default "generated")
      --verbose                    debug gRPC connections

# Environments:

HTTP_GW_KEY=string                           - "generated" to generate key, path to private key file, hex string or wif (default "generated")
HTTP_GW_CONNECT_TIMEOUT=Duration             - timeout for connection
HTTP_GW_REQUEST_TIMEOUT=Duration             - timeout for request
HTTP_GW_REBALANCE_TIMER=Duration             - time between connections checks
HTTP_GW_LISTEN_ADDRESS=host:port             - address to listen connections
HTTP_GW_PEERS_<X>_ADDRESS=host:port          - address of NeoFS Node
HTTP_GW_PEERS_<X>_WEIGHT=float               - weight of NeoFS Node
HTTP_GW_PPROF=bool                           - enable/disable pprof (/debug/pprof)
HTTP_GW_METRICS=bool                         - enable/disable prometheus metrics endpoint (/metrics)
HTTP_GW_LOGGER_FORMAT=string                 - logger format
