OAuther is a library to authenticate using the OAuth 1.0 protocol.
Add the :oauther dependency to your mix.exs file:
defp deps do
[{:oauther, "~> 1.1"}]
endThen, run mix deps.get in your shell to fetch the dependencies.
The example below shows the use of hackney HTTP client for interacting with the Twitter API. Protocol parameters are transmitted using the HTTP "Authorization" header.
creds = OAuther.credentials(consumer_key: "dpf43f3p2l4k3l03", consumer_secret: "kd94hf93k423kf44", token: "nnch734d00sl2jdk", token_secret: "pfkkdhi9sl3r4s00")
#=> %OAuther.Credentials{
#=> consumer_key: "dpf43f3p2l4k3l03",
#=> consumer_secret: "kd94hf93k423kf44",
#=> method: :hmac_sha1,
#=> token: "nnch734d00sl2jdk",
#=> token_secret: "pfkkdhi9sl3r4s00"
#=> }
params = OAuther.sign("post", "https://api.twitter.com/1.1/statuses/lookup.json", [{"id", 485086311205048320}], creds)
