1. Is this request related to a challenge you're experiencing? Tell me about your story.

Create an Agent and then publish it. The front-end accesses the Agent through APIs. The code example is as follows:

curl -X POST 'http://ip:port/v1/chat-messages' \
--header 'Authorization: Bearer {api_key}' \
--header 'Content-Type: application/json' \
--data-raw '{
  "inputs": {},
  "query": "What are the specs of the iPhone 13 Pro Max?",
  "response_mode": "streaming",
  "conversation_id": "",
  "user": "abc-123",
  "files": [
      {
        "type": "image",
      "transfer_method": "remote_url",
      "url": "https://cloud.dify.ai/logo/logo-site.png"
    }
  ]
}'

Note that the user parameter with the value of abc-123 is attached when sending messages. I need to obtain this parameter in the Agent prompt and pass it to the Agent's tools for data permission control. Currently, the user parameter can be viewed in the access logs, but how can this parameter be retrieved during business processing?

extent analysis

TL;DR

The user parameter needs to be retrieved from the API request and passed to the Agent's tools for data permission control during business processing.

Guidance

  • Review the API endpoint http://ip:port/v1/chat-messages to determine how to access the user parameter from the request body.
  • Investigate the Agent's API documentation to find a suitable method for passing the user parameter to the Agent's tools.
  • Consider modifying the Agent's code to extract the user parameter from the request context or headers.
  • Verify that the user parameter is correctly passed to the Agent's tools by checking the Agent's logs or debugging output.

Example

No code example is provided as the issue lacks specific details about the Agent's implementation and API.

Notes

The solution may depend on the specific implementation of the Agent and its API, which is not provided in the issue.

Recommendation

Apply a workaround by modifying the Agent's code to extract the user parameter from the request context or headers, as the issue implies a need for custom implementation.
