gun:request(3)

Name

gun:request - Perform the given request

Description

request(ConnPid, Method, Path, Headers, Body)
    -> request(ConnPid, Method, Path, Headers, Body, #{})

request(ConnPid, Method, Path, Headers, Body, ReqOpts)
    -> StreamRef

ConnPid   :: pid()
Method    :: binary()
Path      :: iodata()
Headers   :: gun:req_headers()
Body      :: iodata()
ReqOpts   :: gun:req_opts()
StreamRef :: gun:stream_ref()

Perform the given request.

This is a general purpose function that should only be used when other method-specific functions do not apply.

The function request/5,6 sends the entire request, including the request body, immediately. It is therefore not possible to use gun:data(3) after that. You should provide a content-type header. Gun will set the content-length header automatically.

Arguments

ConnPid

The pid of the Gun connection process.

Method

Method to be used for the request.

Path

Path to the resource.

Headers

Additional request headers.

Body

Request body.

ReqOpts

Request options.

Return value

A reference that identifies the newly created stream is returned. It is this reference that must be passed in subsequent calls and will be received in messages related to this new stream.

Changelog

• 2.0: Implicit body detection has been removed. The body must now be provided either directly (even if empty) or using gun:headers(3).
• 1.0: Function introduced.

Examples

StreamRef = gun:request(ConnPid, <<"PUT">>,
    "/lang/fr_FR/hello",
    [{<<"content-type">>, <<"text/plain">>}],
    <<"Bonjour !">>).
