HTTPoison v1.4.0 HTTPoison

The HTTP client for Elixir.

The HTTPoison module can be used to issue HTTP requests and parse HTTP responses to arbitrary urls.

iex> HTTPoison.get!("https://api.github.com")
%HTTPoison.Response{status_code: 200,
                    headers: [{"content-type", "application/json"}],
                    body: "{...}"}

It’s very common to use HTTPoison in order to wrap APIs, which is when the HTTPoison.Base module shines. Visit the documentation for HTTPoison.Base for more information.

Under the hood, the HTTPoison module just uses HTTPoison.Base (as described in the documentation for HTTPoison.Base) without overriding any default function.

See request/5 for more details on how to issue HTTP requests

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: see type HTTPoison.Request

Options: see type HTTPoison.Request

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, any, headers, Keyword.t) ::
  HTTPoison.Response.t |
  HTTPoison.AsyncResponse.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.

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.
