FastAPI 返回图像

记录一下，我在网上找了好久都不太管用

from fastapi import FastAPI
from fastapi import FastAPI, File, UploadFile, Response
from fastapi.responses import StreamingResponse



#  返回图片
@app.post("/downloadfile2/")
async def download_files_stream():
    file_like = open('as.png', mode="rb")
    return StreamingResponse(file_like, media_type="image/jpg")
