Overview

Initialize an instance of the Client class. You pass in the service name and optionally hash arguments specifying how the client should access the SoftLayer API.

The following symbols can be used as hash arguments to pass options to the constructor:

  • :username - a non-empty string providing the username to use for requests to the client

  • :api_key - a non-empty string providing the api key to use for requests to the client

  • :endpoint_url - a non-empty string providing the endpoint URL to use for requests to the client

If any of the options above are missing then the constructor will try to use the corresponding global variable declared in the SoftLayer Module:

  • $SL_API_USERNAME

  • $SL_API_KEY

  • $SL_API_BASE_URL

The client class maintains an (optional) default client. The default client will be used by many methods if you do not provide an explicit client.

Constructor Details

#initialize(options = {}) ⇒ Client

Clients are built with a number of settings:

  • :username - The username of the account you wish to access through the API

  • :api_key - The API key used to authenticate the user with the API

  • :enpoint_url - The API endpoint the client should connect to. This defaults to API_PUBLIC_ENDPOINT

  • :user_agent - A string that is passed along as the user agent when the client sends requests to the server

If these arguments are not provided then the client will try to locate them using other sources including global variables, and the SoftLayer config file (if one exists)

#service_named(service_name, service_options = {}) ⇒ Object

Returns a service with the given name.

If a service has already been created by this client that same service will be returned each time it is called for by name. Otherwise the system will try to construct a new service object and return that.

If the service has to be created then the service_options will be passed along to the creative function. However, when returning a previously created Service, the service_options will be ignored.

If the service_name provided does not start with ‘SoftLayer_’ that prefix will be added

Raises:

  • (ArgumentError)
