蓝图的跨域是用了flask-cors库中的CORS, 此方法跨域只处理装饰器式的路由, restful是继承Resource的所以该跨域并不能生效两种方案根据需求选择
方案一(蓝图的跨域直接使用CORS库即可)
from flask_cors import CORS
app = Flask(__name__)
CORS(app, supports_credentials=True)
if __name__ == "__main__":
app.run()
方案二(restful的跨域使用中间件请求后处理头信息)
from flask import make_response
app = Flask(__name__)
@app.after_request
def restful_cros(reshead):
resp = make_response(reshead)
# 项目所需的其他头信息此处都可以添加
resp.headers['Access-Control-Allow-Origin'] = '*'
resp.headers['Access-Control-Allow-Methods'] = 'GET,POST,PUT,DELETE'
resp.headers['Access-Control-Allow-Headers'] = 'x-requested-with,content-type'
return reshead
if __name__ == "__main__":
app.run()
