HTTPoison v1.6.2 HTTPoison View Source

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.)
