Hash Login Example Usage (this is the recommended login technique)¶ ↑

hash = {
    :hosts => [
      # First connect is to remotehost1
      {:login => "login1", :passcode => "passcode1", :host => "remotehost1", :port => 61612, :ssl => true},
      # First failover connect is to remotehost2
      {:login => "login2", :passcode => "passcode2", :host => "remotehost2", :port => 61613, :ssl => false},

    ],
    # These are the default parameters and do not need to be set
    :reliable => true,                  # reliable (use failover)
    :initial_reconnect_delay => 0.01,   # initial delay before reconnect (secs)
    :max_reconnect_delay => 30.0,       # max delay before reconnect
    :use_exponential_back_off => true,  # increase delay between reconnect attpempts
    :back_off_multiplier => 2,          # next delay multiplier
    :max_reconnect_attempts => 0,       # retry forever, use # for maximum attempts
    :randomize => false,                # do not radomize hosts hash before reconnect
    :connect_timeout => 0,              # Timeout for TCP/TLS connects, use # for max seconds
    :connect_headers => {},             # user supplied CONNECT headers (req'd for Stomp 1.1+)
    :parse_timeout => 5,                # receive / read timeout, secs
    :logger => nil,                     # user suplied callback logger instance
    :dmh => false,                      # do not support multihomed IPV4 / IPV6 hosts during failover
    :closed_check => true,              # check first if closed in each protocol method
    :hbser => false,                    # raise on heartbeat send exception
    :stompconn => false,                # Use STOMP instead of CONNECT
    :usecrlf => false,                  # Use CRLF command and header line ends (1.2+)
    :max_hbread_fails => 0,             # Max HB read fails before retry.  0 => never retry
    :max_hbrlck_fails => 0,             # Max HB read lock obtain fails before retry.  0 => never retry
    :fast_hbs_adjust => 0.0,            # Fast heartbeat senders sleep adjustment, seconds, needed ...
                                        # For fast heartbeat senders.  'fast' == YMMV.  If not
                                        # correct for your environment, expect unnecessary fail overs
    :connread_timeout => 0,             # Timeout during CONNECT for read of CONNECTED/ERROR, secs
  }

  # for client
  client = Stomp::Client.new(hash)

  # for connection
  connection = Stomp::Connection.new(hash)

Positional Parameter Usage¶ ↑

client = Stomp::Client.new("user", "pass", "localhost", 61613)
client.publish("/queue/mine", "hello world!")
client.subscribe("/queue/mine") do |msg|
  p msg
end

Stomp URL Usage¶ ↑

# Stomp URL :
A Stomp URL must begin with 'stomp://' and can be in one of the following forms:

stomp://host:port
stomp://host.domain.tld:port
stomp://login:passcode@host:port
stomp://login:[email protected]:port

e.g. c = Stomp::Client.new(urlstring)

Failover + SSL Example URL Usage¶ ↑

options = "initialReconnectDelay=5000&randomize=false&useExponentialBackOff=false"

# remotehost1 uses SSL, remotehost2 doesn't
client = Stomp::Client.new("failover:(stomp+ssl://login1:passcode1@remotehost1:61612,stomp://login2:passcode2@remotehost2:61613)?#{options}")

client.publish("/queue/mine", "hello world!")
client.subscribe("/queue/mine") do |msg|
  p msg
end
