flask-解决跨域问题flask_cors插件

flask后端框架用flask_cors来解决跨域问题

import json

from flask import  Flask,render_template
from flask_cors import CORS   ###########
app=Flask(__name__)

@app.route('/')
def index():
    # return  render_template('index.html')
    return  'hello'

@app.route('/product/getBaseCategoryList')
def getBaseCategoryList():
    return json.dumps({'name':'zh3','age':18})

@app.route('/user')
def getUser():
    return json.dumps({'name':'zh3','age':18})


CORS(app,resources=r'/*')  #设置所有接口都允许被跨域访问

if(__name__=='__main__'):
    app.run()
