I have a activity function that should store message in Blob storage.I can overwrite a file in blob storage but i need to store data in different name.how to do that? Azure function doesn't support dynamic binding in nodejs.

You want to define your own blob name or a random name like sys.randGuid is acceptable?Jerry Liu– Jerry Liu2018-11-15 09:09:06 +00:00Commented Nov 15, 2018 at 9:09

i have used "path" : "azureblob/{rand-guid}" it gives a unique name. but is there a way to specify the name? @JerryLiuNafis Islam– Nafis Islam2018-11-15 09:23:03 +00:00Commented Nov 15, 2018 at 9:23

Find one workaround, see whether it's useful.
Along with blob output binding, there's an activity trigger to receive message msg, we can put self-defined blob name in msg for blob binding path to consume.
In your orchestrator function which calls Activity function
yield context.df.callActivity("YourActivity", {'body':'messagecontent','blobName':'myblob'});
Then Activity function code should be modified
context.bindings.myOutputBlob = context.bindings.msg.body;
And its function.json can use blobName as expected
{
"bindings": [
{
"name": "msg",
"type": "activityTrigger",
"direction": "in"
},
{
"name":"myOutputBlob",
"direction": "out",
"type": "blob",
"connection": "AzureWebJobsStorage",
"path": "azureblob/{blobName}"
}
],
"disabled": false
}
