FastApi 文件上传upload

需要使用的Python包：fastapi和uvicorn。

import time
import uvicorn
from fastapi import FastAPI, File, UploadFile

app = FastAPI()


@app.post("/file_upload")
async def file_upload(file: UploadFile = File(...)):
    start = time.time()
    try:
        res = await file.read()
        with open(file.filename, "wb") as f:
            f.write(res)
        return {
    
    "message": "success", 'time': time.time() - start, 'filename': file.filename}
    except Exception as e:
        return {
    
    "message": str(e), 'time': time.time() - start, 'filename': file.filename}


if __name__ == '__main__':
    uvicorn.run(app=app, host="127.0.0.1", port=8000, workers=1)

客户端代码示例

import requests
url = "http://127.0.0.1:8000/file_upload"
path = "C:\\Users\\omegaxyz\\Desktop\\pic.jpeg"
files = {
    
    'file': open(path, 'rb')}
r = requests.post(url, files=files)
print(r.url)
print(r.text)
