现在web开发已经进入前后端分离的阶段
后端往往只需要吐api数据就ok
一般纯的api接口需要考虑跨域访问问题
下面是简单的跨域访问装饰器在flask中的实现
from functools import wraps
from flask import make_response
def allow_cross_domain(fun):
@wraps(fun)
def wrapper_fun(*args, **kwargs):
rst = make_response(fun(*args, **kwargs))
rst.headers['Access-Control-Allow-Origin'] = '*'
rst.headers['Access-Control-Allow-Methods'] = 'PUT,GET,POST,DELETE'
allow_headers = "Referer,Accept,Origin,User-Agent"
rst.headers['Access-Control-Allow-Headers'] = allow_headers
return rst
return wrapper_fun
@app.route('/hosts/')
@allow_cross_domain
def domains():
pass
