Binding support

This component supports output binding with the following operations:

Create object

To perform a create object operation, invoke the binding with a POST method and the following JSON body:

  "operation": "create",
  "data": "YOUR_CONTENT"


Saving to a random generated UUID file

curl -d "{ \"operation\": \"create\", \"data\": \"Hello World\" }" http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "create", "data": "Hello World" }' http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

Saving to a specific file

curl -d "{ \"operation\": \"create\", \"data\": \"Hello World\", \"metadata\": { \"key\": \"my-key\" } }" http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "create", "data": "Hello World", "metadata": { "key": "my-key" } }' http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

Metadata information

Object key

By default, the Alicloud OSS output binding will auto-generate a UUID as the object key. You can set the key with the following metadata:

    "data": "file content",
    "metadata": {
        "key": "my-key"
    "operation": "create"
