Stsplatform

This gem allows you to use the STS Platform API, including the community version WoTKit.

Dependencies

• Ruby > 2.2.1

Installation

Add this line to your application's Gemfile:

gem 'stsplatform'

And then execute:

$ bundle

Or install it yourself as:

$ gem install stsplatform

Getting Started

Require the stsplatform gem. Make sure to install it To install from source run: "bundle exec rake install" to install from RubyGems run : "gem install stsplatform"

require 'stsplatform'

Create an STS Platform client:

c = STSPlatform::Client.new()

Print a sensor hosted in the platform:

s = STSPlatform::Sensors.new(c, 'calderonroberto.demo')
res = s.get()
puts res.data

Print some data (last data point):

To acccess data from a sensor create a data object that uses the sensor object

d = STSPlatform::Data.new(s)
res = d.get({beforeE:1})
puts res.data

Using the Library

All methods rely on the Client Class. The parameter CONF is not required, but allows you to configure your client to specify your credentials and url of the STS Platform instance you want to access. By default the client will use the community edition of the STS Platform (WoTKit):

A common configuration object is:

CONF = {
  url:"http://wotkit.sensetecnic.com/api",
  auth:{key_id:YOURKEYID,key_password:YOURKEYPASSWORD}
  }

You can then instantiate your client like this:

c = STSPlatform::Client.new(CONF)

To access resources you build them hierarchically. A sensor lives in an STS Platform Server:

c = STSPlatform::Client.new(CONF)
s = STSPlatform::Sensors.new(c, 'SENSORNAME')

Sensor data lives in a Sensor:

c = STSPlatform::Client.new(CONF)
s = STSPlatform::Sensors.new(c, 'SENSORNAME')
d = STSPlatform::Data .new(s)

And so on. Each element that uses the Client class can access GET, POST, PUT and DELETE methods. These methods take parameters and return a STSPlatformResponse object containing "data" and "code". Data is the parsed response from the STS Platform server. Code is a string response code from the STS Platform server:

c = STSPlatform::Client.new(CONF)
s = STSPlatform::Sensors.new(c, 'SENSORNAME')
d = STSPlatform::Data .new(s)
response = d.get({parameter:parametervalue})

puts response.code
puts response.data

Supported Resources

To get started first require the library

require 'stsplatform'

Configuring the Client

By default the library does not need a configuration to access public sensors. You can configure the client to use a different STS Platform URL (in this case the free version 'WoTKit'). You can also configure it to use a username and password or a valid key_id and key_password:

conf = {
  url:"http://wotkit.sensetecnic.com/api",
  #auth:{key_id:YOURKEYID,key_password:YOURKEYPASSWORD}
  #auth:{username:USERNAME,password:PASSWORD}
  }
client = STSPlatform::Client.new(conf)

Get Sensors

c = STSPlatform::Client.new(config)
s = STSPlatform::Sensors.new(c, SENSOR_NAME)
puts s.get().data

Get Data

c = STSPlatform::Client.new(config)
s = STSPlatform::Sensors.new(c, SENSOR_NAME)
d = STSPlatform::Data.new(s)
puts d.get({beforeE:1}).data

Publish Data

c = STSPlatform::Client.new(config)
s = STSPlatform::Sensors.new(c, SENSOR_NAME)
d = STSPlatform::Data.new(s)
puts d.post({value:100}).code #print response code
puts d.get({beforeE:1}).data

Get Sensor Fields

c = STSPlatform::Client.new(config)
s = STSPlatform::Sensors.new(c, SENSOR_NAME)
fs = STSPlatform::Fields.new(s)
puts fs.get().data
f = STSPlatform::Fields.new(s, "value")
puts f.get().data

Organizations

c = STSPlatform::Client.new(config)
o = STSPlatform::Orgs.new(c, 'sensetecnic')
puts o.get().data

Development

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

• To install this gem onto your local machine, run bundle exec rake install.
• To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
