HTTPoison

Summary
Types
Functions

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.

Args:

method - HTTP method as an atom (:get, :head, :post, :put, :delete, etc.)
url - target url as a binary string or char list

headers - HTTP headers as an orddict (e.g., `[{:Accept, "application/json"}]`)
options - orddict of options

Options:

:timeout - the timeout (in milliseconds) of the request
:stream_to - a PID to stream the response to

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