Usage
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)
#=> [
#=> {"oauth_signature", "ariK9GrGLzeEJDwQcmOTlf7jxeo="},
#=> {"oauth_consumer_key", "dpf43f3p2l4k3l03"},
#=> {"oauth_nonce", "L6a3Y1NeNwbU9Sqd6XnwNU+pjm6o0EyA"},
#=> {"oauth_signature_method", "HMAC-SHA1"},
#=> {"oauth_timestamp", 1517250224},
#=> {"oauth_version", "1.0"},
#=> {"oauth_token", "nnch734d00sl2jdk"},
#=> {"id", 485086311205048320}
#=> ]
{header, req_params} = OAuther.header(params)
#=> {{"Authorization",
#=> "OAuth oauth_signature=\"ariK9GrGLzeEJDwQcmOTlf7jxeo%3D\", oauth_consumer_key=\"dpf43f3p2l4k3l03\", oauth_nonce=\"L6a3Y1NeNwbU9Sqd6XnwNU%2Bpjm6o0EyA\", oauth_signature_method=\"HMAC-SHA1\", oauth_timestamp=\"1517250224\", oauth_version=\"1.0\", oauth_token=\"nnch734d00sl2jdk\""},
#=> [{"id", 485086311205048320}]}
:hackney.post("https://api.twitter.com/1.1/statuses/lookup.json", [header], {:form, req_params})
#=> {:ok, 200, [...], #Reference<0.0.0.837>}
