To return an image and JSON in one response in FastAPI, you can create a response that contains both the image and JSON data. Below is an example of how you can achieve this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
from fastapi import FastAPI, Response
from fastapi.responses import StreamingResponse
import json
app = FastAPI()
@app.get("/image-json")
async def get_image_json():
# Get the image data
image_data = open("image.jpg", "rb").read()
# Create a JSON response
json_data = {"message": "This is a JSON response"}
# Create a combined response with the image and JSON data
response_data = {
"image": image_data,
"json": json_data
}
# Return a StreamingResponse with the combined data
return StreamingResponse(content=json.dumps(response_data), media_type="application/json")
|
In this example, we first read the image data from a file and create a JSON response. We then combine the image and JSON data into a dictionary and convert it to a JSON string. Finally, we return a StreamingResponse with the combined data and set the media type to "application/json".
When you make a request to the "/image-json" endpoint, you will receive a response containing both the image and JSON data.
