Azure Functions how to add application settings to bindings

Question

I'm trying to add some custom binding using my app settings for my Azure Function. I need to receive only string a string from my settings.

I would like to get simpleValue from my settings.

{
   "bindings": [
    {
      "name": "someValue",
      "type": "stringSetting",
      "connection": "simpleValue",
      "direction": "in"
    }
  ],
  "disabled": false
}

and the get it in Run method:

static void GetOrders(TraceWriter log, string someValue)
{
    log.Info(someValue);
}

Is it even possible. Maybe there is other way to do it?

Answer 1

App Settings configurations can be referred in binding json as %MY_CUSTOM_CONFIG% - enclosed within percent symbols.

Note that the connection property of triggers and bindings is a special case and automatically resolves values as app settings, without percent signs. https://docs.microsoft.com/en-us/azure/azure-functions/functions-triggers-bindings

Answer 2

I already found the solution. Just add:

using System.Configuration;

and add this line to code with the key ("simpleValue") value:

ConfigurationManager.AppSettings["simpleValue"]
