How to Create Blob Output Bind with Queue Trigger Azure Function

Question

While Passing Blob name into Azure Function, it won't able to trigger while adding message to Queue

Not Working

#r "Newtonsoft.Json"
using System;
using Newtonsoft.Json;

public static void Run(string myQueueItem, 
 Stream outputBlob, 
ILogger log)
{
    log.LogInformation($"C# Queue trigger function processed: {myQueueItem}");
    dynamic data = JsonConvert.DeserializeObject(myQueueItem);
    log.LogInformation($"We got a new Queue Request Type: {data.MessageType}");
    if(data.MessageType == "Create Blob")
    {
        //  outputBlob = data.Message;
    }
    // outputBlob = "";
    string blobFileName = "tettet.script";
}

Working

I want the File To be created as the queue message contain in body section.

Also need to assign the Blob File Name from Queue Object as parameter.(uploadedscript/{blobFileName})

A side note: Recommendation is to not use script version (.csx) of Functions but start right with pre-compiled Functions. Sooner or later you will end up there anyway ;-) stackoverflow.com/a/51404225/1537195 — silent

Use the code as below:

using System;

public static void Run(string myQueueItem,out string outputBlob,ILogger log)
{
    log.LogInformation($"C# Queue trigger function processed: {myQueueItem}");

    outputBlob=myQueueItem;
}

And the function.json:

{
  "bindings": [
    {
      "name": "myQueueItem",
      "type": "queueTrigger",
      "direction": "in",
      "queueName": "queue",
      "connection": "AzureWebJobsStorage"
    },
    {
      "type": "blob",
      "name": "outputBlob",
      "path": "container/{queueTrigger}",
      "connection": "AzureWebJobsStorage",
      "direction": "out"
    }
  ]
}
