Current REST API

Account

• To create account:
  • POST http://localhost:3000/users/setup {"email": "a@b.com","username":"admin","password": "00000000"}
• To login:
  • POST http://localhost:3000/users/login (Header contains Authorization: Basic <base64 encode of username:password)

Services

Services may requested by selector. A service selector is an object with the following fields:

• (optional) string `id`: accept only a service with a given id;
• (optional) string array of string `tags`: accept only services with all the tags in the array;
• (optional) object or array of objects `getters` (see GetterSelector): accept only services with channels matching all the selectors in this array;
• (optional) object or array of objects `setters` (see SetterSelector): accept only services with channels matching all the selectors in this array.

Generally, except for (de)assigning tags, using an id is considered a bad idea, as this ties the application to a specific device, and this will fail if the device is replaced (consider that this is equivalent to using an IP address instead of a domain name).

List of Services

Example with 1 selector:

• Get services with tag "location: kitchen" and channel kind "OvenTemperature"
  • GET http://localhost:3000/api/v1/services { tags: "location: kitchen", setters: { kind: "OvenTemperature" } }

Example with 2 selectors:

• Get services with tag "location: kitchen" or "location: entrance":
  • GET http://localhost:3000/api/v1/services [{ tags: "location: kitchen" }, {tags: "location: entrance"}]

As a shortcut, providing no argument will locate all services:

• Get all services:
  • GET http://localhost:3000/api/v1/services

Tags

• Assign Tags to a service
  • POST http://localhost:3000/api/v1/services/tags {"services": selector(s), "tags": tag(s)}

• Remove Tags of a service
  • DELETE http://localhost:3000/api/v1/services/tags {"services": selector(s), "tags": tag(s)}

• Example
  • POST http://localhost:3000/api/v1/services/tags {"services":[{"id":"thinkerbell-root-service"}],"tags":["Living Room"] }

Channels

Channels are designed to be used by selector.

A selector is an object with the following fields:

• (optional) string id: accept only a channel with a given id;
• (optional) string `service`: accept only channels of a service with a given id;
• (optional) string|array of string `tags`: accept only channels with all the tags in the array;
• (optional) string|array of string `service_tags`: accept only channels of a service with all the tags in the array;
• (optional) string|object `kind` (see ChannelKind): accept only channels of a given kind.

While each field is optional, at least one field must be provided.

Generally, except for (de)assigning tags, using an id is considered a bad idea, as this ties the application to a specific device, and this will fail if the device is replaced (consider that this is equivalent to using an IP address instead of a domain name).

Fetching

• Fetch values from all channels matching any of the selectors
  • PUT http://localhost:3000/api/v1/channels/get selector(s)

Example:

• • PUT http://localhost:3000/api/v1/channels/get [{"tags": "location: entrance", kind: "OpenClosed"}

Sending

• Send one values to all channels matching any of the selectors:

   PUT http://localhost:3000/api/v1/channels/set {"select": selector(s), "value": value}

or

• Send a bunch of values to all channels matching any of the selectors:

   PUT http://localhost:3000/api/v1/channels/set [{"select": selector(s), "value": value}, {"select": selector(s), "value: value}, ...]

See http://fxbox.github.io/taxonomy/doc/foxbox_taxonomy/values/enum.Value.html for the full documentation on values.

Example (with CURL)

The following snippet displays "Hello world" on all the devices that support Log, in particular the console.

   curl -X PUT http://localhost:3000/api/v1/channels/set -d '{"select":{"kind":"Log"},"value":{"String":"Hello, world"}}'

Tags

• Assign Tags to a channel
  • POST http://localhost:3000/api/v1/channels/getter/tags {"getter": selector(s), "tags": tag(s)}
  • POST http://localhost:3000/api/v1/channels/setter/tags {"setter": selector(s), "tags": tag(s)}

• Remove Tags of a channel
  • DELETE http://localhost:3000/api/v1/channels/getter/tags {"getter": selector(s), "tags": tag(s)}
  • DELETE http://localhost:3000/api/v1/channels/setter/tags {"setter": selector(s), "tags": tag(s)}

  • POST http://localhost:3000/api/v1/services {"setters":[{"kind":{"adapter":"Adapter","kind":"snapshot","type": "Json", "vendor":"DLink"} }]}

Recipe

A recipe is a set of *rules*.

Each rule is triggered when *all* its *conditions* are true. A condition is specified by a set of channels to watch and a range of values that make it true - the condition becomes true once *any* of the channels it watches provides a value that fits the range.

Once a rule is triggered, it *executes*. An execution sends one value to a set of channels.

Once a rule is triggered, it won't be triggered again until at least one of the conditions has become false and true again.

Format:

 {
   rules: one or more of {
     conditions: one or more of {
       source: one or more of Selectors (see section on channels)
       kind: see documentation of channel kinds
       range: see documentation of ranges
       duration: (optional) floating point number of seconds
     }
     execute: one or more of {
       destination: one or more Selectors (see section on channels)
       kind: see documentation of channel kinds
       value: see documentation of values
     }
   }
 }

• Send Recipe

To Be Documented: Use channel selector {"kind": "AddThinkerbellRule"}.

• List available Recipes

To Be Documented: Use service selector {"getters": {"kind": "ThinkerbellRuleSource"}}}.
