Flask跨域

Flask跨域

当前后端分离写的时候,不同的服务器访问会导致跨域问题,有以下两种解决办法

1.用flask_cors

pip install flask_cors

from flask_cors import CORS
CORS(app, supports_credentials=True)

2.设置Access-Control-Allow-Origin

@api.after_request
def add_header(response):
 	response.headers['Access-Control-Allow-Origin'] = '*'
	response.headers['Access-Control-Allow-Headers'] = 'Content-Type,Authorization'
	return response
