comment—utils—output.py

from flask import make_response, current_app from flask_restful.utils import PY3 from json import dumps# todo 将字典格式的响应数据转化为json格式的响应数据 def output_json(data, code, headers=None):"""Makes a Flask response with a JSON encoded body"""#todo 此处添加自己定义的json格式规则，把返回给前端的数据做一个封装，以便于前端可以使用统一的规则解析数据if 'message' not in data:data = {# 'message':'OK','code': 200, # 自动的将状态200封装到json中'data': data}settings = current_app.config.get('RESTFUL_JSON', {})# If we're in debug mode, and the indent is not set, we set it to a# reasonable value here. Note that this won't override any existing value# that was set. We also set the "sort_keys" value.if current_app.debug:settings.setdefault('indent', 4)settings.setdefault('sort_keys', not PY3)# always end the json dumps with a new line# see https://github.com/mitsuhiko/flask/pull/1262#todo 将字典转化为jsondumped = dumps(data, **settings) + "\n"resp = make_response(dumped, code)resp.headers.extend(headers or {})return resp

使用：在资源视图中（创建蓝图的py文件中）定义

user_api.representation('aplication/json')(output_json)
