PUT: Send PUT request to server.


Send PUT request to server.


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



the url of the page to retrieve


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().


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.


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.


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.
