Create a "registry" website

[cmaneu]

In step 1, attendees will register their Azure Functions to the proctor's registry. We need a small web page to allows them to auto register.

Data Storage Let's store it in an Azure Table Storage. PartitionKey : event code (like devfestnantes19) RowKey : deviceId from IoT Hub Device Registry callbackUrl : an HTTP/s URL of the attendee Azure Function

Interface

• A Combobox with the list of devices, and in parenthesis the status (Connected or not). Get these infos by calling the IoT Device Registry It should be Azure.Devices nuget.
• an input field for entering the callback url
• a button to save it
• a button to send a test message to the callback url (from the backend).

No need for AJAX, if an MVC web app is easier.

Features

• List devices
• Set a callback URL (can set an empty URL, or have a "clear" button)
• Send a test message

About the test message I'll confirm Thursday morning the JSON schema, but just send a dummy JSON by doing an HTTP Post request to the specified URI. The JSON will look like this :

{
    "deviceId": "device-24",
    "temperature": 23.4,
    "pressure": 1004.9,
    "humidity": 52.7
}

(P1 or P2): You should also display the result of that request. The response format should like this:

{
    "state": "running/idle",
    "led": 
    {
        "r": 255,
        "g": 0,
        "b": 0
    }
}

The ComboBox, the input field and the Save button are implemented and deployed. It reads the list of devices from the IoT Hub registry and populate a DropDownList. It also reads the previously saved callback urls. When the user selects a device in the DropDownList, if there is a previously saved callback url for this device, it is displayed in the input field. When the user clicks on the Save button, the callback url is written to a table storage. If there is a previsous callback url, it is replaced.
