    This topic created in 1980 days ago, the information mentioned may be changed or developed.

    想让每个 resp 都按照这样的三段式返回:

    {
        "data": xxx,
        "msg": xxx,
        "code": xxx
    }
    

    现在想的是用装饰器,这样可以实现视图函数的返回都按照这个来;但是有一些框架返回的东西没有办法按照这个 schema 返回,想问还有什么更好的办法吗?

    import json
    from flask import Flask, Response


    class MyResponse(Response):
    def __init__(self, response, **kwargs):
    response = json.dumps({'data': 'xxx', 'msg': 'xxx', 'code': 'xxx'})
    return super(MyResponse, self).__init__(response, **kwargs)


    app = Flask(__name__)
    app.response_class = MyResponse


    @app.route('/')
    def index():
    return 'I will be overrided'
