mercury v0.1.1 Mercury
A simple wrapper for the Mercury Web Parser API, powered by HTTPoison.
The Mercury Parser extracts the bits that humans care about from any URL you give it. That includes article content, titles, authors, published dates, excerpts, lead images, and more.
To use, just run:
{:ok, response} = Mercury.parse(url)
# -- OR --
%{body: body} = Mercury.parse!(url)

Issues an HTTP request with the given method to the given url.
This function is usually used indirectly by get/3

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 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
sslerlang module *
:follow_redirect- a boolean that causes redirects to be followed *

:infinityThis 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!(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.
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
.
