flask通过一个装饰器解决跨域问题

from flask import Flask, make_response
import json
from functools import wraps

app = Flask(__name__)


def add_allow_origin(name):
    def mid(func):
        @wraps(func)
        def inner(*args, **kwargs):
            resp = func(*args, **kwargs)
            resp = make_response(resp)
            resp.access_control_allow_origin = name
            return resp
        return inner
    return mid


@app.route('/')
@add_allow_origin('*')
def index():
    reponse = json.dumps(dict(
        name='zhao',
        age=12
    ))
    return reponse


@app.route('/12')
@add_allow_origin("http://localhost:63342")
def index_():
    reponse = json.dumps(dict(
        name='zhafsado',
        age=12
    ))
    return reponse

    app.run(debug=True, host='0.0.0.0')
