JSON format

Device families VT855i, VT960i, VT855t support API requests in JSON format.

When accessing the server, you need to specify the CGI program to which the request is being sent. For general queries, this is "engine.htm". Thus, the full path will be http://192.168.0.193/engine.htm.

To exchange messages in JSON format, the MIME content type must be specified in the POST request header as 'Content-Type: application/json'.

Input requests should have the following format:

{
  "auth":{
    "name":"guest", 
    "p":"guest", 
    "h":"35675e68f4b5af7b995d9205ad0fc43842f16450"
  }
}

Here "auth" is the querytype name of the request type.

Next come the "key:value" parameter pairs corresponding to the request type. You can see the names of these fields in the API description.

Response messages have the following format:

{
  "user":{
    "id":"1",
    "k":"123456789",
    "name":"guest",
    "sread":"all,",
    "swrite":"all,",
    "cread":"",
    "cwrite":"",
    "gread":"all,",
    "gwrite":"all,",
    "mail":"",
    "phone":""
  }
}

Here "user" corresponds to the tag name for the XML structures defined in the API. Next follow are "key:value" parameter pairs.

Not all requests in JSON format are supported yet. As far as possible, we will fill in these gaps.
