Send a DELETE request.

DELETE(url = NULL, config = list(), ..., body = NULL,
  encode = c("multipart", "form", "json", "raw"), handle = NULL)

Arguments

url

the url of the page to retrieve

config

Additional configuration settings such as http authentication (authenticate()), additional headers (add_headers()), cookies (set_cookies()) etc. See config() for full details and list of helpers.

...

Further named parameters, such as query, path, etc, passed on to modify_url(). Unnamed parameters will be combined with config().

body

One of the following:

  • FALSE: No body. This is typically not used with POST, PUT, or PATCH, but can be useful if you need to send a bodyless request (like GET) with VERB().

  • NULL: An empty body

  • "": A length 0 body

  • upload_file("path/"): The contents of a file. The mime type will be guessed from the extension, or can be supplied explicitly as the second argument to upload_file()

  • A character or raw vector: sent as is in body. Use content_type() to tell the server what sort of data you are sending.

  • A named list: See details for encode.

encode

If the body is a named list, how should it be encoded? Can be one of form (application/x-www-form-urlencoded), multipart, (multipart/form-data), or json (application/json).

For "multipart", list elements can be strings or objects created by upload_file(). For "form", elements are coerced to strings and escaped, use I() to prevent double-escaping. For "json", parameters are automatically "unboxed" (i.e. length 1 vectors are converted to scalars). To preserve a length 1 vector as a vector, wrap in I(). For "raw", either a character or raw vector. You'll need to make sure to set the content_type() yourself.

handle

The handle to use with this request. If not supplied, will be retrieved and reused from the handle_pool() based on the scheme, hostname and port of the url. By default httr requests to the same scheme/host/port combo. This substantially reduces connection time, and ensures that cookies are maintained over multiple requests to the same host. See handle_pool() for more details.

Value

A response() object.

RFC2616

The DELETE method requests that the origin server delete the resource identified by the Request-URI. This method MAY be overridden by human intervention (or other means) on the origin server. The client cannot be guaranteed that the operation has been carried out, even if the status code returned from the origin server indicates that the action has been completed successfully. However, the server SHOULD NOT indicate success unless, at the time the response is given, it intends to delete the resource or move it to an inaccessible location.

A successful response SHOULD be 200 (OK) if the response includes an entity describing the status, 202 (Accepted) if the action has not yet been enacted, or 204 (No Content) if the action has been enacted but the response does not include an entity.

If the request passes through a cache and the Request-URI identifies one or more currently cached entities, those entries SHOULD be treated as stale. Responses to this method are not cacheable.
