如何在fastapi中同时返回image和json？

from fastapi import FastAPI
from fastapi.responses import JSONResponse
from fastapi.responses import FileResponse

app = FastAPI()

@app.get("/image_and_json")
async def get_image_and_json():
    # 读取图像文件
    image_file = "path/to/image.jpg"
    
    # 构建JSON数据
    json_data = {
        "message": "Hello, World!",
        "data": {
            "key": "value"
        }
    }
    
    # 返回图像和JSON
    return {
        "image": FileResponse(image_file, media_type="image/jpeg"),
        "json": JSONResponse(content=json_data)
    }

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)
