如何为 flask_cors 设置 Access-Control-Max-Age?

How to set Access-Control-Max-Age for flask_cors?

在我的烧瓶应用程序中,我需要设置Access-Control-Max-Age。它的正确语法是什么?

from flask import Flask, send_from_directory
from flask_cors import CORS, cross_origin
app = Flask(__name__,static_folder='./build') 
CORS(app)

参考:https://flask-cors.readthedocs.io/en/latest/api.html

看看 flask_cors.CORS 部分,max_age 部分。

max_age (timedelta, integer, string or None)

The maximum time for which this CORS request maybe cached. This value is set as the Access-Control-Max-Age header.

根据文档,您可能需要使用此参数初始化 CORS

CORS(app, max_age=3600)
