verb-POST function

HTTP verb info: POST

The POST method is used to submit an entity to the specified resource, often causing a change in state or side effects on the server.

The POST method

If one or more resources has been created on the origin server as a result of successfully processing a POST request, the origin server SHOULD send a 201 (Created) response containing a Location header field that provides an identifier for the primary resource created (Section 7.1.2 https://datatracker.ietf.org/doc/html/rfc7231#section-7.1.2) and a representation that describes the status of the request while referring to the new resource(s).

Examples

## Not run:

x <- HttpClient$new(url = "https://hb.opencpu.org")

# a named list
x$post(path='post', body = list(hello = "world"))

# a string
x$post(path='post', body = "hello world")

# an empty body request
x$post(path='post')

# encode="form"
res <- x$post(path="post",
  encode = "form",
  body = list(
    custname = 'Jane',
    custtel = '444-4444',
    size = 'small',
    topping = 'bacon',
    comments = 'make it snappy'
  )
)
jsonlite::fromJSON(res$parse("UTF-8"))

# encode="json"
res <- x$post("post",
  encode = "json",
  body = list(
    genus = 'Gagea',
    species = 'pratensis'
  )
)
jsonlite::fromJSON(res$parse())
