FastAPI 接受 POST 上传文件并保存本地，python

设置文件路径

读取成二进制数据,然后写入文件

import os
 
import uvicorn
from fastapi import FastAPI, File, UploadFile
 
app = FastAPI()
 
 
@app.post("/file/upload")
async def upload(file: UploadFile = File(...)):
    fn = file.filename
    save_path = f'./file/'
    if not os.path.exists(save_path):
        os.mkdir(save_path)
 
    save_file = os.path.join(save_path, fn)
 
    f = open(save_file, 'wb')
    data = await file.read()
    f.write(data)
    f.close()
 
    return {"msg": f'{fn}上传成功', 'length': len(data)}
 
 
if __name__ == '__main__':
    uvicorn.run(app=app, host="0.0.0.0", debug=True)
