posting sensor data to Rails app - Raspberry Pi Forums

how can post sensor data rails app via rpi? (preferably using ruby or javascript )

not sure if makes difference planning use mcp3008 analog-to-digital converter.

write in javascript node.js. sending data server via http post request easy as:

code: select all

var request = require('request'); var myjsonobject = { x: 1,  y: 666, z: 42};  request({     url: "http://josiahchoi.com/myjson",     method: "post",     json: true,   // <--very important!!!     body: myjsonobject }, function (error, response, body){     console.log(response); });
