• Function Description

    Real-time data of all monitoring points is actively pushed by the server. Clients can control the opening of one or more monitoring groups. After opening, when data changes in the enabled group (changes that exceed the dead zone setting), the server actively pushes it to the client. The push function depends on the SignalR library.

Creating a SignalR Connection

  • Request URL

    URL:SignalR URL obtained from the FGate listExplanation of terms

    querystring: at={token}&cid={X-FBox-ClientId}

    Field Type Description
    token string Access token obtained from the login interface
    X-FBox-ClientId string See Appendix One

    SignalR Service Hub Name: clientHub

Note
1、The token is valid for approximately two hours. 401 indicates token expiration. For new parameters, you need to re-call the login interface to get the access_token.

​ For old parameters, you need to refresh the access_token by re-logging in with the refresh_token. The refresh_token is valid for 30 days.
​ 2、Java demo and C# SDK handle token refresh and Signalr reconnection issues. If not using the demo, you need to handle this process in the program.

​ 3、 Signalr should maintain a long connection, develop with singletons.
