How to dump http "content-type: application/json;" in fastapi?

In FastAPI, you can define the content type of the response using the Response class. To dump content in json format with content type application/json, you can do the following:

from fastapi import FastAPI, Response
import json

app = FastAPI()

@app.get("/json_response")
async def create_json_response():
    data = {"key": "value"}
    response = Response(content=json.dumps(data), media_type="application/json")
    return response

In the above example, we create a simple FastAPI application with a GET endpoint that returns a JSON response. We use the Response class to create a response object, passing the JSON data as content and setting the media type to application/json. This way, we can ensure that the content type of the response is set to application/json.
