redirect-handling

Redirect handling

If the option :follow_redirect is given, HTTP redirects are automatically follow if the method is set to :get or :head and the response's status_code is 301, 302 or 307.

If the method is set to :post, then the only status_code that get's automatically followed is 303.

If any other method or status_code is returned, then this function returns a returns a {:ok, %HTTPoison.MaybeRedirect{}} containing the redirect_url for you to re-request with the method set to :get.

examples

Examples

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