erlangRestHttpService

HTTP server with REST API to store measures written in erlang

yaws.conf should be modified like this to work (of course you should modify paths to your environment):

ebin_dir = /var/git/httpRestService/ebin
ebin_dir = /var/git/httpRestService/lib/ebin/jiffy

In server configuration (<server name>) have to be line:

appmods = \<pathName,httpRestService\>

(service will be available at adres: http://name/pathName/measures )

Operations:

GET

• for "measures" - returns list of measurers
• for "measures/measurerName" - returns measures of this measurer (it's possible to do this: "measures/measurerName?limit=X (ie. limit=10) to return last X of measures)

POST

• for "measures" it allows to add new measurer to database. Fields:
  • name - administrator login
  • password - administrator password
  • measurer - measurer name
  • measurerPassword - measurer password

PUT

• for "measures/measurerName" allows to add new measure; can be used "application/x-www-form-urlencoded" or "application/json". For both fields are:
  • password - measurer password
  • timestamp - timestamp of measure
