Azure Function Environment Variable
Environment Variable helps you to store any custom settings for your Azure Function. This is the main purpose of the Environment Variable.
You can configure or manage these custom settings in the Application Settings of the Azure Function App. To reach out to this option, You can log in to the Azure Portal, navigate to your Azure Function App, and click on the Configuration from the left side menu on your Azure Function App page. Now you can find the option Application settings.
We can use the GetEnvironmentVariable() to access the value of the Environment Variable.
Example
If we will see an example below is the MyNewHTTPNewFunction Azure Function, where we have used the GetEnvironmentVariable method.
[FunctionName("MyNewHTTPNewFunction
")]
public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
ILogger log, ExecutionContext context)
{
log.LogInformation("MyNewHTTPNewFunction processed a request.");
log.LogInformation(GetEnvironmentVariable("MY_PRODUCT_NAME"));
var NewSetting = Environment.GetEnvironmentVariable("MyNewSetting", EnvironmentVariableTarget.Process);
return Task.FromResult(req.CreateResponse(HttpStatusCode.OK, new { setting= NewSetting }));
Now, in your local.settings.json file of your Azure Function, you should mention “MY_PRODUCT_NAME” and the value for this key. GetEnvironmentVariable(“MY_PRODUCT_NAME”) retrieves the value for this key, which is “Your Product name” in this case.
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "dotnet",
"MY_PRODUCT_NAME": "Your Product Name"
}
}
