API - Getting current registers values

---

To get a list of all registers, you must perform a GET request on the URL like this: http://192.168.1.1/api/registers.

In the headers, it is necessary to pass API key. For example:

X-WH-APIKEY: F3C74230818DA487BB2017CE5D0290F4DABCAFD7

In the request headers, you must pass the connection IDs (IDs). Register values ​​will be returned only from those connections whose ID are specified in the X-WH-CONNS header. ID should be separated by comma, without spaces. This allows you to request not all registers, but only a part.

Example:

X-WH-CONNS: 1,2

In this example, register values for the ID=1 and ID=2 will be returned.

Also, in the headers, you must specify the desired data exchange format. Currently, only the JSON format is supported.

Accept: application/json
Content-Type: application/json

Example of the response:

{
  "1": {
    "r": "1",
    "v": "-1",
    "s": "i"
  },
  "2": {
    "r": "2",
    "v": "-1",

    "r": "3",
    "v": "-1",
    "s": "i"
  },
  "4": {
    "r": "4",
    "v": "1422600498",

    "s": "u"
  },
  "9": {
    "r": "9",
    "v": "0",
    "s": "u"
  }
}

The format of the returned data is as follows:
Returns the object, where the property names are register IDs. And the properties themselves are yet another objects.
Each object has three properties: r, v, s.

'r' is the register ID. For example, 10
'v' is the value of the register at the current time or '-1' if the value does not work.
's' is the state of the register that matched it at the specified time. Unknown = u, Disabled = d, Normal = n, Warning = w, Alert = a, Incorrect = i.
