ex_metra v0.1.0 ExMetra.Web
This is the module that interacts with the Metra JSON API. It uses HTTPoison as the base in order to make the actual calls. It will use the same functions as HTTPoison. Because of the fact that it uses the @endpoint as the base of the url, it will only be able to be used to call the Metra API. Do not use this if you are looking to make calls to other websites or services. Do note that basic authorization will already be present in the web calls so it is not necessary to add the headers when making a request. Because Basic Authorization is already included it is important to set the necessary values in your config.exs. The following values must be present in your config.exs for any web calls to be successful:
config :ex_metra,
access_key: “
Usage: ExMetra.Web.get(url)

Processes the request headers before the actual web call. This is a callback from the HTTPoison.Base. It adds basic authorization into the headers so that it isn’t needed to be entered in any other get calls using this module. It only adds to the headers and does not remove any extra header values so it will not affect any headers that are actually passed in
Processes the url before the actual web call. This is a callback from the HTTPoison.Base. It is used in order to prepend the base url common to all API calls
Issues a PUT request to the given url
Issues a PUT request to the given url, raising an exception in case of failure
Issues an HTTP request with the given method to the given url
Issues an HTTP request with the given method to the given url, raising an exception in case of failure
Starts HTTPoison and its dependencies

request(atom(), binary(), any(), 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 listbody
- request body. See more belowheaders
- 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 tostream_next

tuple:ssl
- SSL options supported by thessl
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}

request is successful, {:error, reason}
otherwise.
Examples
request(:post, "https://my.website.com", "{\"foo\": 3}", [{"Accept", "application/json"}])
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.
Starts HTTPoison and its dependencies.
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
.
