How to use execHttpRequestAction and it complete functionality

Answered
Permanently deleted user

Hi

I am using Event in the application through APIs while exploring documents I came across the "execHttpRequestAction" event type. Is it possible to add an event that will send Notification to my server through HTTP URL provided while creating Events like push notification. It will be very helpful if we can receive a notification on our server as if the camera goes online or motion detected.

If it is possible can you please share sample payload.

    Hi Vishal,

    The execHttpRequestAction event type corresponds to Do HTTP request action in "Camera rules..." window of Nx Desktop.

    You can read more about configuring camera rules in the built-in Nx user manual of Nx Desktop.

    For more details, let me first explain the general idea and schema and afterwards the method of how to make the solution automated.
    Let's assume, you want to feed motion detection event on a camera with ID "camera1" to your middleware.

    Here is the manual procedure.

    1. Create a type 1 rule.
    When: Motion on Camera.
    At: camera1
    Action: Do HTTP Request.
    HTTP URL: the URL for api/createEvent API for triggering Generic Event.
    For example,
    http://127.0.0.1:7001/api/createEvent?source=camera1&caption=caption1&description=desctription1

    2. Create a type 2 rule.
    This is supposed to be a rule for processing Generic event, triggered by Type 1 rule.
    In our example it should be configured similar to
    When: Generic Event
    Source contains: camera1
    Caption contains: caption1
    Description contains: description1
    Action: Do HTTP Request.
    The "HTTP URL" and "HTTP content" should contain your middleware specific code. In order to pass values insert into you code
    {event.source}
    {event.caption}
    {event.description}

    In our example,
    {event.source}=camera1
    {event.caption}=caption1
    {event.description}=description1

    You could refer to https://support.networkoptix.com/hc/en-us/community/posts/360031203493-Surpress-temporarily-actions-showOnAlarmLayout-and-showNotification-for-a-specific-camera
    for detailed example of configuring Generic rule and Do HTTP Request action.

    To make configuration easier you probably want to make a script for creating these types of rules, which would comprise such steps.

    1. Identify cameras, the rules have to be created for.
    - you could insert special symbols to camera name
    - you could read cameras from a config files (camera names or ip addresses or camera ID)

    2. Determine camera ID by calling /ec2/getCamerasEx and parsing the output and filtering the camera based on the data of step 1.

    3. Create rules type 1 and type 2
    - call getEventRules for checking already existing rules
    - to avoid duplicates you could put some tags in the "comment:" field.
    - create/update rules by calling saveEventRule

    Of course, while automating the stage Stage 1. Create a type 1 rule. via API you can right away put the code of the request to your middleware to HTTP URL and HTTP Content fields, and avoid stage 2. Create a type 2 rule, because from  /ec2/getCamerasEx you know all information on camera needed to build specific HTTP request parameters.

    Thanks Andrey Terentyev

    But I want to receive a notification on my custom server on which I am integrating Network Optix through APIs. I want to know if there is any method in which I gave an API to Event Rule and whenever motion is detected it will hit given API with the post or put method and send details in the request body.

    Hello Vishal,
     
    > I want to know if there is any method in which I gave an API to Event Rule and whenever motion is detected it will hit given API with the post or put method and send details in the request body.
    You create a rule: the motion detection event triggers "Do HTTP Request" action, http URL and request body of which can be defined by you in tune with your API  of your custom server.
    Nx Server: Motion detection -> "Do HTTP Request" action -> http  API request -> your custom server.

    That is exactly what I've described. Please, read the recent post and try to do step by step in Nx Desktop.

    Hi Andrey,

    I created a generic event and configured the 'http post' action with following HTTP content as below:

    {
        "name": {event.source},
        "description": {event.description}
    }
     
    This did not work. Can you help me in getting the post content correct?

    It works now. I have not made any changes as such. Were there any updates recently?

    Hi Vamsi,

    Andrey is currently on vacation, so I will be monitoring the forum instead of him for some time. It would be easier for me to answer your question if I knew which software version did you use when the issue was present and which version you're using now.

    Could you please share this info? Thank you.

    Hi Maxim,

    I had one version on windows (4.1.0.31398) and one in ubuntu(4.0.0.29987). None of the systems had never been updated as per the 'about info'.

    Now I am using ubuntu only. I shall get back in case of any issue.

    Please confirm if this feature works on above mentioned windows version too.

    No updates since the release.

    I'd recommend you upgrade to the latest v4.1 release.
