gun:headers - Initiate the given request

Description

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

headers(ConnPid, Method, Path, Headers, ReqOpts)
    -> StreamRef

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

Initiate the given request.

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

The function headers/4,5 initiates a request but does not send the request body. It must be sent separately using gun:data(3).

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.
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: Function introduced.

Examples
