这对我有用：

curl -F "file=@image.jpg" http://localhost:5000/

@很重要，否则您将遇到一个HTTP错误400（服务器无法理解请求）。我还删除了 -X POST位，因为这是不必要的。

The '@' is important, otherwise you end up with an http error 400 (server could not understand request). I've also dropped the "-X POST" bit as it's unnecessary.

我的烧瓶视图：

from PIL import Image

@app.route("/", methods=["POST"])
def home():
    img = Image.open(request.files['file'])
    return 'Success!'
