python - flask-restful 中文返回的响应变成了 unicode literal

问题描述

问 题

下面的示例代码，运行在 Python 2.7 环境

pip install flask-restful flask

# -*- coding:utf-8 -*-
from flask import Flask
from flask_restful import Api, Resource, reqparse, marshal_with, fields

class Greetings(Resource):
    def get(self, message=None):
        message = '中文한국어'
        greeting = 'You have received a message: {0}'.format(message) if message else 'zzzzzzz......'
        return greeting, 200

app = Flask(__name__)

api = Api(app)

api.add_resource(Greetings, '/radio/', '/radio/<message>')


if __name__ == '__main__':
    app.run(port=8000,debug=True)

这是运行的结果：

? Discuq@iDocker: ~ => curl  http://127.0.0.1:8000/radio/ 
"You have received a message: \u4e2d\u6587\ud55c\uad6d\uc5b4"

期望得到的结果是：

? Discuq@iDocker: ~ => curl  http://127.0.0.1:8000/radio/ 
"You have received a message: 中文한국어"

解决方案

指定 RESTFUL_JSON 配置项：

app = Flask(__name__)
app.config.update(RESTFUL_JSON=dict(ensure_ascii=False))
