  {:ok, HTTPoison.Response.t | HTTPoison.AsyncResponse.t} |
  {:error, HTTPoison.Error.t}

Issues an HTTP request with the given method to the given url.

This function is usually used indirectly by get/3, post/4, put/4, etc

Args:

method - HTTP method as an atom (:get, :head, :post, :put, :delete, etc.)
url - target url as a binary string or char list
body - request body. See more below
headers - HTTP headers as an orddict (e.g., [{"Accept", "application/json"}])
options - Keyword list of options

Body:

binary, char list or an iolist
{:form, [{K, V}, ...]} - send a form url encoded
{:file, "/path/to/file"} - send a file
{:stream, enumerable} - lazily send a stream of binaries/charlists

Options:

:timeout - timeout to establish a connection, in milliseconds. Default is 8000
:recv_timeout - timeout used when receiving a connection. Default is 5000
:stream_to - a PID to stream the response to
:async - if given :once, will only stream one message at a time, requires call to stream_next
:proxy - a proxy to be used for the request; it can be a regular url or a {Host, Port} tuple
:proxy_auth - proxy authentication {User, Password} tuple
:ssl - SSL options supported by the ssl erlang module
:follow_redirect - a boolean that causes redirects to be followed
:max_redirect - an integer denoting the maximum number of redirects to follow
:params - an enumerable consisting of two-item tuples that will be appended to the url as query string parameters

Timeouts can be an integer or :infinity

This function returns {:ok, response} or {:ok, async_response} if the request is successful, {:error, reason} otherwise.

Examples

request(:post, "https://my.website.com", "{\"foo\": 3}", [{"Accept", "application/json"}])

request!(method, url, body \\ "", headers \\ [], options \\ [])

request!(atom, binary, body, headers, Keyword.t) :: HTTPoison.Response.t

Issues an HTTP request with the given method to the given url, raising an exception in case of failure.

request!/5 works exactly like request/5 but it returns just the response in case of a successful request, raising an exception in case the request fails.

start()

Starts HTTPoison and its dependencies.

start(type, args)

Called when an application is started.

This function is called when an application is started using Application.start/2 (and functions on top of that, such as Application.ensure_started/2). This function should start the top-level process of the application (which should be the top supervisor of the application’s supervision tree if the application follows the OTP design principles around supervision).

start_type defines how the application is started:

:normal - used if the startup is a normal startup or if the application is distributed and is started on the current node because of a failover from another node and the application specification key :start_phases is :undefined.
{:takeover, node} - used if the application is distributed and is started on the current node because of a failover on the node node.
{:failover, node} - used if the application is distributed and is started on the current node because of a failover on node node, and the application specification key :start_phases is not :undefined.

start_args are the arguments passed to the application in the :mod specification key (e.g., mod: {MyApp, [:my_args]}).

This function should either return {:ok, pid} or {:ok, pid, state} if startup is successful. pid should be the PID of the top supervisor. state can be an arbitrary term, and if omitted will default to []; if the application is later stopped, state is passed to the stop/1 callback (see the documentation for the c:stop/1 callback for more information).

use Application provides no default implementation for the start/2 callback.

Callback implementation for Application.start/2.

stream_next(resp)

stream_next(HTTPoison.AsyncResponse.t) ::
  {:ok, HTTPoison.AsyncResponse.t} |
  {:error, HTTPoison.Error.t}

Requests the next message to be streamed for a given HTTPoison.AsyncResponse.

See request!/5 for more detailed information.
