CookieJar

Installation

The package can be installed by adding cookie_jar to your list of dependencies in mix.exs:

def deps do
  [{:cookie_jar, "~> 1.0"}]
end

Usage

1. Add alias (optional)

alias CookieJar.HTTPoison, as: HTTPoison

2. Get a cookie jar

{:ok, jar} = CookieJar.new

Alternatively, you can use a permenent cookie jar by starting one as part of your supervision tree:

def start(_type, _args) do
  children = [
  {CookieJar.Server, name: MyApp.CookieJar},
  ...

Then you can use MyApp.CookieJar as the application-wide jar.

3. Shove the jar into all http calls

- HTTPoison.get("https://example.com/api/call")
+ HTTPoison.get(jar, "https://example.com/api/call")

4. Profit (cookies imprisoned) All cookies from "Set-Cookie:" response headers are now stored in the jar and will be automatically sent back through "Cookie:" request headers. CookieJar respect the following attributes in the cookies:

• Domain: To limit abuses, CookieJar only allows Domain to be set to the current hostname of the request or its immediate parent domain.
• Path: A cookie can limit the sending back to part of the path tree in the request
• Secure: A secure cookie can only be set by https responses and used by https requests
• Max-Age: A cookie can specify its max age

All other attributes are silently ignored.
