🚀3. Consume Microservice

3.1 Consume Upload API

Once document preparation microservice for Elasticsearch is started, user can use below command to invoke the microservice to convert the document to embedding and save to the database.

curl -X POST \
    -H "Content-Type: application/json" \
    -d '{"path":"/path/to/document"}' \
    http://localhost:6011/v1/dataprep

3.2 Consume get_file API

To get uploaded file structures, use the following command:

curl -X POST \
    -H "Content-Type: application/json" \
    http://localhost:6011/v1/dataprep/get_file

Then you will get the response JSON like this:

[
  {
    "name": "uploaded_file_1.txt",
    "id": "uploaded_file_1.txt",
    "type": "File",
    "parent": ""
  },
  {
    "name": "uploaded_file_2.txt",
    "id": "uploaded_file_2.txt",
    "type": "File",
    "parent": ""
  }

    -d '{"file_path": "https://www.ces.tech/.txt"}' \
    http://localhost:6011/v1/dataprep/delete_file

# delete file
curl -X POST \
    -H "Content-Type: application/json" \
    -d '{"file_path": "uploaded_file_1.txt"}' \
    http://localhost:6011/v1/dataprep/delete_file

# delete all files and links
