8.2. JSON access
8.2.1. JSON login (encrypted password)
The encrypted login sequence is similar to the XML access:
Step 1:
Request
http://192.168.1.100/current_state.json
Reply (login required):
{
"CurrentState": { "LoginKey": "65156" }
}
Step 2:
Request (password is sent as a parameter)
http://192.168.1.100/current_state.json?pw=28237099263eabfd88626124a822c64c
Reply (password is O’K, login accepted):
{
"CurrentState": {
"DigitalInput": [
{"Name": "DIn1", "Value": "1"},
…
}
Password encryption algorithm to be implemented in custom application is
available upon request.
8.2.2. JSON login (non-encrypted password)
The password should be passed as non-encrypted parameter with the request:
http://192.168.1.100/current_state.json?pw=admin
Getting the
“LoginKey”
in the answer means only that the provided password is
wrong or the login session has been expired.
If there is no data traffic between the custom application and the
SmartDEN IP-32IN for time, specified by
Session Timeout
parameter,
the session "times out" and a new login is required.
8.2.3. Retrieving current state in JSON format
When logged, the custom application can get current measurements requesting
the
current_state.json
page. The reply contains a page in JSON format (Fig. 54).
