1. 创建 FastAPI 应用并编写文件上传接口 from fastapi import FastAPI, File, UploadFile from typing import List import shutil app = FastAPI() @user.post("/uploadfile/") async def upload_file(file: UploadFile = File(...)): if not os.path.exists("uploads"): os.makedirs("uploads") # 获取...
app=FastAPI()@app.post("/upload/")asyncdefupload_file(file:UploadFile=File(...),description:str=Form(...)):try:content=awaitfile.read()# 可以在这里进行文件处理return{"filename":file.filename,"description":description,"content_type":file.content_type}finally:awaitfile.close()@app.get("/"...
from fastapi import FastAPI, File, UploadFile # 方法一:上传的文件会存在内存中,适合小型文件 async def create_file(file: Annotated[bytes, File()]): return {"file_size": len(file)} # 方法二:UploadFile async def create_upload_file(file: UploadFile): return {"filename": file.filename} # ...

在这个示例中,我们首先定义了一个上传文件的路由函数 upload_file,当用户上传文件时,我们首先将文件保存到服务器上,然后创建一个异步任务 process_file,用于处理上传的文件。在 process_file 函数中,我们模拟了一个 IO 操作,然后将处理后的文件保存到服务器上。

from fastapi import FastAPI, File, UploadFile app = FastAPI() @app.post("/uploadfile/") async def upload_file(file: UploadFile = File(...)): return {"filename": file.filename} 在这个例子中,当用户上传文件时,FastAPI会将文件信息存储在UploadFile对象中。UploadFile具有几个有用的属性和方法,如fi...
