  HTTPoison.AsyncResponse.t

Issues a HEAD request to the given url, raising an exception in case of failure.

If the request does not fail, the response is returned.

See request!/5 for more detailed information.

Link to this function init(state) View Source

Invoked when the server is started. start_link/3 or start/3 will block until it returns.

args is the argument term (second argument) passed to start_link/3.

Returning {:ok, state} will cause start_link/3 to return {:ok, pid} and the process to enter its loop.

Returning {:ok, state, timeout} is similar to {:ok, state} except handle_info(:timeout, state) will be called after timeout milliseconds if no messages are received within the timeout.

Returning {:ok, state, :hibernate} is similar to {:ok, state} except the process is hibernated before entering the loop. See c:handle_call/3 for more information on hibernation.

Returning :ignore will cause start_link/3 to return :ignore and the process will exit normally without entering the loop or calling c:terminate/2. If used when part of a supervision tree the parent supervisor will not fail to start nor immediately try to restart the GenServer. The remainder of the supervision tree will be (re)started and so the GenServer should not be required by other processes. It can be started later with Supervisor.restart_child/2 as the child specification is saved in the parent supervisor. The main use cases for this are:

  • The GenServer is disabled by configuration but might be enabled later.
  • An error occurred and it will be handled by a different mechanism than the Supervisor. Likely this approach involves calling Supervisor.restart_child/2 after a delay to attempt a restart.

Returning {:stop, reason} will cause start_link/3 to return {:error, reason} and the process to exit with reason reason without entering the loop or calling c:terminate/2.

Callback implementation for GenServer.init/1.

  {: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:

  • binary, char list or an iolist
  • {:form, [{K, V}, ...]} - send a form url encoded
  • {:file, "/path/to/file"} - send a file
  • {:stream, enumerable} - lazily send a stream of binaries/charlists

Options:

  • :timeout - timeout to establish a connection, in milliseconds. Default is 8000
  • :recv_timeout - timeout used when receiving a connection. Default is 5000
  • :stream_to - a PID to stream the response to
  • :async - if given :once, will only stream one message at a time, requires call to stream_next
  • :proxy - a proxy to be used for the request; it can be a regular url or a {Host, Port} tuple
  • :proxy_auth - proxy authentication {User, Password} tuple
  • :ssl - SSL options supported by the ssl erlang module
  • :follow_redirect - a boolean that causes redirects to be followed
  • :max_redirect - an integer denoting the maximum number of redirects to follow
  • :params - an enumerable consisting of two-item tuples that will be appended to the url as query string parameters

Timeouts can be an integer or :infinity

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"}])
Link to this function request!(method, url, body \\ "", headers \\ [], options \\ []) View Source 
request!(atom, binary, any, headers, Keyword.t) :: HTTPoison.Response.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.

Link to this function start() View Source

Starts HTTPoison and its dependencies.

Link to this function stream_next(resp) View Source 
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.

See request!/5 for more detailed information.
