WebSocket Service

A web socket server application. The application listen to the default web socket port and get a connection from a web socket client.

I'm using the following chrome extension for the test:

https://chrome.google.com/webstore/detail/simple-websocket-client/pfdhoblngboilpfeibdedpjgfnlcodoo?hl=en

The application receive a json payload as described below and validate the json schema.

In case of successful validation, a json response will be sent back to the client with the same batch_id as was received in the input json.

In case of failure in one of the validations rule a json response will be sent back to the client with the error description.

Upon a request to the client, both request and response json files logged in a local directory.

The request payload will have the following Structure:

{
    "action": {
         "method": "traffilog_task_1_http",
         "parameters": {
             "batch_id": 10,
             "vehicle_id": 1234578,
             "timestamp": "2020-11-15T15:50:38.000"
        }
    }
}

Json schema validations:

Parameter name	Type	Mandatory	Description
method	String (100)	TRUE
batch_id	Number	TRUE
vehicle_id	Number	FALSE
Timestamp	Date time	TRUE	Cannot be a future date

The response body will have the following structure:

{
    "action": {
        "method ": "traffilog_task_1_http",
        "response": {
            "batch_id": 10,
            "status": "OK",
            "description": "SUCCESS"
        }
    }
}

{
    "action": {
        "method ": "traffilog_task_1_http",
        "response": {
            "status": "ERROR",
            "description": "Missing Mandatory Field"
        }
    }
}

"description" field:

This field return one of the following error types in case of error:

• Missing Mandatory Field
• Validation Error
