消息未从 Azure Function 添加到 Azurite 队列

Question

Following the documentation below I trying to create an azure function which adds a message to a queue.

https://docs.microsoft.com/en-us/azure/azure-functions/functions-add-output-binding-storage-queue-vs?tabs=in-process#add-an-output-binding

The code gets triggered and executes with out an error, but I could not see any message in the Azure Storage Explorer Queue.

I added Azurite Storage account to my local Storage Explorer. But the queue does not get created and the message is not getting added.

AzureWebJobsStorage is set to "UseDevelopmentStorage=true".

How do I test this locally in the storage explorer? What are the steps and what all do I need?

I tried to reproduce the issue by following steps:

1. Created Azure Functions (Stack: .Net Core 3.1 - Http Trigger) in Visual Studio.
2. Installed this package Microsoft.Azure.WebJobs.Extensions.Storage through Nuget Package Solution to the Project.
3. Added the Output Queue binding to the Task static method like:

public static async Task<IActionResult> Run( [HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = null)] HttpRequest req, [Queue("outqueue"), StorageAccount("AzureWebJobsStorage")] ICollector<string> msg, ILogger log)

Added the code which writes the passed parameter in the function URL to the output queue (before parsing the response message code):

if (!string.IsNullOrEmpty(name))
    {
    // Add a message to the output collection.
    msg.Add(string.Format("Name passed to the function: {0}", name));
    }

Now the full code looks is:

local.settings.json

{
    "IsEncrypted": false,
    "Values": {
        "AzureWebJobsStorage": "UseDevelopmentStorage=true",
        "FUNCTIONS_WORKER_RUNTIME": "dotnet"
    }
}

5. Run the function locally and copy the function URL that comes in the console to the browser along with parameters like: http://localhost:7071/api/Function1?name=HariKrishna Then it should be displayed in the browser as Hello, HariKrishna. This HTTP triggered function executed successfully. Hello, HariKrishna. This HTTP triggered function executed successfully.

6. Go to the Storage Explorer > Expand Queues and refresh it ( right-click on queues and click refresh ) to see the queue created by functions runtime while a function is running and refresh the output queue also to see the messages as you can the console output, browser output and Queue messages in below screenshot:
