@spec request(HTTPoison.Request.t()) ::
  {:ok,
   HTTPoison.Response.t()
   | HTTPoison.AsyncResponse.t()
   | HTTPoison.MaybeRedirect.t()}
  | {:error, HTTPoison.Error.t()}

Issues an HTTP request using an HTTPoison.Request struct.

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

Redirect handling

If the option :follow_redirect is given, HTTP redirects are followed internally by hackney when the method is :get or :head and the response's status_code is 301, 302 or 307, and when the method is :post and the status_code is 303. Redirects are resolved up to :max_redirect hops and the final response is returned.

As of hackney 4.0 redirects are resolved inside hackney, so a HTTPoison.MaybeRedirect is no longer returned. The struct is retained only for backward compatibility.

Examples

request = %HTTPoison.Request{
  method: :post,
  url: "https://my.website.com",
  body: "{\"foo\": 3}",
  headers: [{"Accept", "application/json"}]
}

  {:ok,
   HTTPoison.Response.t()
   | HTTPoison.AsyncResponse.t()
   | HTTPoison.MaybeRedirect.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: 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.

@spec request!(HTTPoison.Request.t()) ::
  HTTPoison.Response.t()
  | HTTPoison.AsyncResponse.t()
  | HTTPoison.MaybeRedirect.t()

Issues an HTTP request an HTTPoison.Request struct. exception in case of failure.

request!/1 works exactly like request/1 but it returns just the response in case of a successful request, raising an exception in case the request fails.

@spec request!(method(), binary(), any(), headers(), Keyword.t()) ::
  HTTPoison.Response.t()
  | HTTPoison.AsyncResponse.t()
  | HTTPoison.MaybeRedirect.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.

Starts HTTPoison and its dependencies.

@spec 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.
