Crystal Lang Digest Auth

Build Status

Communicate with servers that implement digest auth.

Installation

  1. Add the dependency to your shard.yml:
   dependencies:
     digest-auth:
       github: spider-gazelle/digest-auth
  1. Run shards install

Usage

require "http/client"
require "digest-auth"

# New client per-connection, this keeps track of nonce count
digest_auth = DigestAuth.new

uri = URI.parse "http://foo.com/posts?id=30&limit=5"

# if you expect digest auth use a head request to get the challenge header
client = HTTP::Client.new uri
response = client.head uri.full_path
response.status_code # => 401

challenge = response.headers["WWW-Authenticate"]
uri.user = "username"
uri.password = "password"

# Generate the auth header, need to indicate if talking to IIS
auth_header = digest_auth.auth_header(uri, challenge, "get", iis: false)

# Make the request
response = client.get uri.full_path, HTTP::Headers{ "Authorization" => auth_header }
response.status_code # => 200

# Make a second request while the connection is still open
uri.path = "/posts/30"
auth_header = digest_auth.auth_header(uri, challenge, "post", iis: false)
response = client.post uri.full_path, HTTP::Headers{ "Authorization" => auth_header }, body: "hello!"
response.status_code # => 201

or using .before_request

require "http/client"
require "digest-auth"

digest_auth = DigestAuth.new
uri = URI.parse "http://foo.com/"

client = HTTP::Client.new uri
response = client.head uri.full_path
response.status_code # => 401

challenge = response.headers["WWW-Authenticate"]
uri.user = "username"
uri.password = "password"

client.before_request do |request|
  req_path = URI.parse request.resource
  uri.path = req_path.path
  uri.query = req_path.query
  auth_header = digest_auth.auth_header(uri, challenge, request.method, iis: false)
  request.headers["Authorization"] = auth_header
end

client.get "/"
client.post "/some_path", body: "hello!"
