  14. value: "myqueue"
  15. # - name: ttlInSeconds
  16. # value: "60"

encodeBase64NOutputIf enabled base64 encodes the data payload before uploading to Azure storage queues. Default false.true, false
endpointNInput/OutputOptional custom endpoint URL. This is useful when using the Azurite emulator or when using custom domains for Azure Storage (although this is not officially supported). The endpoint must be the full base URL, including the protocol (http:// or https://), the IP or FQDN, and optional port.http://127.0.0.1:10001 or https://accountName.queue.example.com

Azure Active Directory (Azure AD) authentication

The Azure Storage Queue binding component supports authentication using all Azure Active Directory mechanisms. See the docs for authenticating to Azure to learn more about the relevant component metadata fields based on your choice of Azure AD authentication mechanism.

Binding support

This component supports both input and output binding interfaces.

This component supports output binding with the following operations:

  • create

Specifying a TTL per message

Time to live can be defined on queue level (as illustrated above) or at the message level. The value defined at message level overwrites any value set at queue level.

To set time to live at message level use the metadata section in the request body during the binding invocation.

The field name is ttlInSeconds.

Example:

  1. curl -X POST http://localhost:3500/v1.0/bindings/myStorageQueue \
  2. -H "Content-Type: application/json" \
  3. -d '{
  4. "data": {
  5. "message": "Hi"
  6. },
  7. "metadata": {
  8. "ttlInSeconds": "60"
  9. },
  10. "operation": "create"
  11. }'
