discourse_elixir v0.2.0 DiscourseElixir

This is a Discourse client for Elixir that builds upon HTTPoison.Base.

This module is primarily intended to allow for the creation and management of Discourse users. More functionality may be added, though it is not a priority.

Functions

create_user(name, email, password)
create_user(string, string, string) ::
  {:ok, map | string} |
  {:error, map | HTTPoison.Error.t}

Issues a POST request to create a user with the provided params.

If successful, returns {:ok, body}. If Discourse doesn’t create the user due to a username or email already being taken, or the password not being valid, returns some variation of {:error, %{errors: %{"email" => [], "password" => ["is too short (minimum is 10 characters)"], "username" => ["must be unique"]}}} If HTTPoison throws an error, returns {:error, reason}

create_user!(name, email, password)
create_user!(string, string, string) ::
  map |
  string |
  HTTPoison.Error.t

Issues a POST request to create a user with the provided params, raising an error if the request fails.

This function works the same way as create_user/3 but only returns the response when the request is successful. If the request fails, an error is raised.

Issues a DELETE request to the given url.

Returns {:ok, response} if the request is successful, {:error, reason} otherwise.

Issues a GET request to the given url.

Returns {:ok, response} if the request is successful, {:error, reason} otherwise.

request(method, url, body \\ "", headers \\ [], options \\ [])
request(atom, binary, body, headers, Keyword.t) ::
  {:ok, HTTPoison.Response.t | HTTPoison.AsyncResponse.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:

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

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, Proxy} 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"}])
request!(method, url, body \\ "", headers \\ [], options \\ [])
request!(atom, binary, body, 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.

start()

Starts HTTPoison and its dependencies.

stream_next(async_response)

Requests the next message to be streamed for a given HTTPoison.AsyncResponse.

See request!/5 for more detailed information.

user(username)
user(string) ::
  {:ok, map | string} |
  {:error, HTTPoison.Error.t}

Issues a GET request for the given user, returning the full response body or that the user doesn’t exist.

If successful, returns {:ok, %{user: %{"foo" => "bar", ...}, user_badges: []}} or {:ok, "User not found"} If an error is raised, returns {:error, reason}

user!(username)
user!(string) :: map | string | HTTPoison.Error.t

Issues a GET request for the given user, returning the full response body or that the user doesn’t exist, and raising an error if the request fails.

This function works the same as user/1 but only returns the body when the request is successful. If the request fails, an error is raised.

user_id(username)
user_id(string) ::
  {:ok, integer | string} |
  {:error, HTTPoison.Error.t}

Issues a GET request for the given user, returning the user’s id or that the user doesn’t exist

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

user_id!(username)
user_id!(string) :: integer | string | HTTPoison.Error.t

Issues a GET request for the given user, returning the user’s id or that the user doesn’t exist, and raising an error if it fails.

This function works the same as user_id/1 but only returns value when there is a successful request. If the request fails, an error is raised.
