python flask 实现跨域问题 flask-cors

• 1. 首先先引入库
• 2. 配置
• • 2.1全局配置
  • 2.2单行路由配置

pip install flask-cors

使用 CORS函数 配置全局路由

from flask import Flask, request
from flask_cors import CORS

app = Flask(__name__)
CORS(app, supports_credentials=True)

使用 @cross_origin 来配置单行路由
from flask import Flask, request
from flask_cors import cross_origin

app = Flask(name)

@app.route(’/’)
@cross_origin(supports_credentials=True)
def hello():
name = request.args.get(“name”, “World”)
return f’Hello, {name}!’
