Overview

Instances of this class represent a REST connection to a JSS API.

For most cases, a single connection to a single JSS is all you need, and this is ruby-jss’s default behavior.

If needed, multiple connections can be made and used sequentially or simultaneously.

Using the default connection

When ruby-jss is loaded, a not-yet-connected default instance of JSS::APIConnection is created and stored in the constant JSS::API. This connection is used as the initial ‘active connection’ (see below) so all methods that make API calls will use it by default. For most uses, where you’re only going to be working with one connection to one JSS, the default connection is all you need.

Before using it you must call its #connect method, passing in appropriate connection details and credentials.

Example:

require 'ruby-jss'
JSS.api.connect server: 'server.address.edu', user: 'jss-api-user', pw: :prompt
# (see {JSS::APIConnection#connect} for all the connection options)

a_phone = JSS::MobileDevice.fetch id: 8743

# the mobile device was fetched through the default connection

Using Multiple Simultaneous Connections

Sometimes you need to connect simultaneously to more than one JSS. or to the same JSS with different credentials. ruby-jss allows you to create as many connections as needed, and gives you three ways to use them:

  1. Making a connection ‘active’, after which API calls go thru it automatically

    Example:

    a_computer = JSS::Computer.fetch id: 1234

# the JSS::Computer with id 1234 is fetched from the active connection
# and stored in the variable 'a_computer'

    NOTE: When ruby-jss is first loaded, the default connection (see above) is the active connection.

  2. Passing an APIConnection instance to methods that use the API

    Example:

    a_computer = JSS::Computer.fetch id: 1234, api: production_api

# the JSS::Computer with id 1234 is fetched from the connection
# stored in the variable 'production_api'. The computer is
# then stored in the variable 'a_computer'

  3. Using the APIConnection instance itself to make API calls.

    Example:

    a_computer = production_api.fetch :Computer, id: 1234

# the JSS::Computer with id 1234 is fetched from the connection
# stored in the variable 'production_api'. The computer is
# then stored in the variable 'a_computer'

See below for more details about the ways to use multiple connections.

NOTE: Objects retrieved or created through an APIConnection store an internal reference to that APIConnection and use that when they make other API calls, thus ensuring data consistency when using multiple connections.

Similiarly, the data caches used by APIObject list methods (e.g. JSS::Computer.all, .all_names, and so on) are stored in the APIConnection instance through which they were read, so they won’t be incorrect when you use multiple connections.

Making new APIConnection instances

New connections can be created using the standard ruby ‘new’ method.

If you provide connection details when calling ‘new’, they will be passed to the #connect method immediately. Otherwise you can call #connect later.

production_api = JSS::APIConnection.new(
  name: 'prod',
  server: 'prodserver.address.org',
  user: 'produser',
  pw: :prompt
)

# the new connection is now stored in the variable 'production_api'.

Using the ‘Active’ Connection

While multiple connection instances can be created, only one at a time is ‘the active connection’ and all APIObject-based access methods in ruby-jss will use it automatically. When ruby-jss is loaded, the default connection (see above) is the active connection.

To use the active connection, just call a method on an APIObject subclass that uses the API.

For example, the various list methods:

all_computer_sns = JSS::Computer.all_serial_numbers

# the list of all computer serial numbers is read from the active
# connection and stored in all_computer_sns

Fetching an object from the API:

victim_md = JSS::MobileDevice.fetch id: 832

# the variable 'victim_md' now contains a JSS::MobileDevice queried
# through the active connection.

The currently-active connection instance is available from the JSS.api method.

Making a Connection Active

Only one connection is ‘active’ at a time and the currently active one is returned when you call JSS.api or its alias JSS.active_connection

To activate another connection just pass it to the JSS.use_api method like so:

JSS.use_api production_api
# the connection we stored in 'production_api' is now active

To re-activate to the default connection, just call

JSS.use_default_connection

Connection Names:

As seen in the example above, you can provide a ‘name:’ parameter (a String or a Symbol) when creating a new connection. The name can be used later to identify connection objects.

If you don’t provide one, the name is ‘:disconnected’ until you connect, and then ‘user@server:port’ after connecting.

The name of the default connection is always :default

To see the name of the currently active connection, just use JSS.api.name

JSS.use_api production_api
JSS.api.name  # => 'prod'

JSS.use_default_connection
JSS.api.name  # => :default

Creating, Storing and Activating a connection in one step

Both of the above steps (creating/storing a connection, and making it active) can be performed in one step using the JSS.new_api_connection method, which creates a new APIConnection, makes it the active connection, and returns it.

 production_api2 = JSS.new_api_connection(
   name: 'prod2',
   server: 'prodserver.address.org',
   user: 'produser',
   pw: :prompt
 )

JSS.api.name  # => 'prod2'

All methods that use the API can take an ‘api:’ parameter which contains an APIConnection object. When provided, that APIconnection is used rather than the active connection.

For example:

prod2_computer_sns = JSS::Computer.all_serial_numbers, api: production_api2

# the list of all computer serial numbers is read from the connection in
# the variable 'production_api2' and stored in 'prod2_computer_sns'

prod2_victim_md = JSS::MobileDevice.fetch id: 832, api: production_api2

# the variable 'prod2_victim_md' now contains a JSS::MobileDevice queried
# through the connection 'production_api2'.

Using the APIConnection itself to make API calls.

Rather than passing an APIConnection into another method, you can call similar methods on the connection itself. For example, these two calls have the same result as the two examples above:

prod2_computer_sns = production_api2.all :Computer, only: :serial_numbers
prod2_victim_md = production_api2.fetch :MobileDevice, id: 832

Here are the API calls you can make directly from an APIConnection object. They behave practically identically to the same methods in the APIObject subclasses, since they just call those methods, passing themselves in as the APIConnection to use.

Low-level use of APIConnection instances.

For most cases, using APIConnection instances as mentioned above is all you’ll need. However to access API resources that aren’t yet implemented in other parts of ruby-jss, you can use the methods #get_rsrc, #put_rsrc, #post_rsrc, & #delete_rsrc documented below.

For even lower-level work, you can access the underlying RestClient::Resource inside the APIConnection via the connection’s #cnx attribute.

APIConnection instances also have a #server attribute which contains an instance of Server q.v., representing the JSS to which it’s connected.

#my_distribution_point(refresh = false) ⇒ JSS::DistributionPoint

Get the DistributionPoint instance for the machine running this code, based on its IP address. If none is defined for this IP address, use the result of master_distribution_point

Parameters:

  • refresh (Boolean) (defaults to: false) —

    should the distribution point be re-queried?

Returns:

end

#my_network_segments ⇒ Array<Integer>

Find the current network segment ids for the machine running this code

Returns:

  • (Array<Integer>) —

    the NetworkSegment ids for this machine right now.

  network_segments_for_ip JSS::Client.my_ip_address
end

#network_ranges(refresh = false) ⇒ Hash{Integer => Range}

All NetworkSegments in this jss as IPAddr object Ranges representing the Segment, e.g. with starting = 10.24.9.1 and ending = 10.24.15.254 the range looks like:

<IPAddr: IPv4:10.24.9.1/255.255.255.255>..#<IPAddr: IPv4:10.24.15.254/255.255.255.255>

Using the #include? method on those Ranges is very useful.

Parameters:

  • refresh (Boolean) (defaults to: false) —

    should the data be re-queried?

Returns:

  • (Hash{Integer => Range}) —

    the network segments as IPv4 address Ranges

  end
  @network_ranges
end

#network_segments_for_ip(ip) ⇒ Array<Integer>

Find the ids of the network segments that contain a given IP address.

Even tho IPAddr.include? will take a String or an IPAddr I convert the ip to an IPAddr so that an exception will be raised if the ip isn’t a valid ip.

Parameters:

  • ip (String, IPAddr) —

    the IP address to locate

  • refresh (Boolean) —

    should the data be re-queried?

Returns:

  • (Array<Integer>) —

    the ids of the NetworkSegments containing the given ip
