 Reverse App requesting means plugins can access App data in Dify. This module supports both streaming and non-streaming App calls.

​
Endpoints Type:

  • For Chatbot/Agent/Chatflow type applications, they are all chat-type applications, having the same input and output parameters, thus can be uniformly viewed as a Chat Interface.
  • For Workflow applications, they occupy a separate Workflow Interface.
  • For Completion (text generation) applications, they occupy a separate Completion Interface.
Note: Plugins can only access Apps within the same Workspace as the plugin.

​
Requesting Chat Interface Entry Point

​
Entry

self.session.app.chat

​
Endpoint Specification

def invoke(
    self,
    app_id: str,
    inputs: dict,
    response_mode: Literal["streaming", "blocking"],
    conversation_id: str,
    files: list,
) -> Generator[dict, None, None] | dict:
    pass
When response_mode is streaming, the interface returns Generator[dict], otherwise returns dict. For specific interface fields, refer to ServiceApi return results.

​
Example

We can request a Chat type App in an Endpoint and directly return the results: 
import json
from typing import Mapping
from werkzeug import Request, Response
from dify_plugin import Endpoint

class Duck(Endpoint):
    def _invoke(self, r: Request, values: Mapping, settings: Mapping) -> Response:
        """
        Invokes the endpoint with the given request.
        """
        app_id = values["app_id"]
        def generator():
            response = self.session.app.workflow.invoke(
                app_id=app_id, inputs={}, response_mode="streaming", files=[]
            )
            for data in response:
                yield f"{json.dumps(data)} <br>"
        return Response(generator(), status=200, content_type="text/html")
