HTTP Rest Server

[shikokuchuo]

Experimental

Permits evaluation of arbitrary R expressions submitted to an API endpoint.

Client-neutral, supporting any HTTP client.

Run server in a new session:

Rscript -e 'nanonext::server("http://127.0.0.1:5555/api/rest")'

Query using command line curl:

curl -X POST http://127.0.0.1:5555/api/rest -d 'format(Sys.time())'

Query from within R:

ncurl("http://127.0.0.1:5555/api/rest", method = "POST", data = "format(Sys.time())")

res <- ncurl(
  "http://127.0.0.1:5555/api/rest",
  convert = FALSE,
  method = "POST",
  data = "data.frame(random = nanonext::random(3))"
)
unserialize(res$data)

Result is returned as a string where possible supporting non-R clients e.g. command line curl.
Otherwise as a binary R-serialized object, which may be consumed by an R client.

TO-DO:

• 1. Parse-error handling
• 2. Consider other return formats
