jQuery posting valid json in request body

by

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you’re sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don’t have the JSON object, use json2.js which will add it in.

What’s currently happening is since you have processData: false, it’s basically sending this: ({"command":"on"}).toString() which is [object Object]…what you see in your request.
