1、使用 jsonify 返回 ASCII 码

使用 jsonify 返回中文时，出现如下乱码（其实是 ASCII 码）

解决：

为 flask 添加如下代码

flask_app.config['JSON_AS_ASCII'] = False

完整代码如下：

# -*- coding:utf-8 -*-

from flask import Flask

from flask_cors import CORS

from api.MovieAPI import movies

# initiate a flask object

flask_app = Flask(__name__, template_folder="templates", static_folder="static")

# support cross domain access

CORS(flask_app, supports_credentials=True)

# register blueprint

flask_app.register_blueprint(movies, url_prefix="/movies")

# don't use json as ascii

flask_app.config['JSON_AS_ASCII'] = False

# set json sort key to false

flask_app.config['JSON_SORT_KEYS'] = False

if __name__ == '__main__':

    flask_app.run(host='0.0.0.0', port=8082)

2、返回 json 中文乱码

如果发现加上 1 中的代码后，仍然出现乱码，如下：

也是由于直接使用 jsonify 返回时，没有 Content-Type 的 Headers

解决：

使用 flask response 方式返回，并且设置 Content-Type 的值

response = make_response(jsonify(json_string))
response.headers['Content-Type'] = 'application/json;charset=UTF-8'

修改前：

# -*- coding:utf-8 -*-
from flask import jsonify
from flask import make_response

def result_success(data):

    json_result = {

        "status": "200",

        "msg": "request success",

        "data": data,

    }

    return jsonify(json_result)

def result_failed(msg, code='400'):

    json_result = {

        "status": code,

        "msg": msg,

    }

    return jsonify(json_result)

修改后：

# -*- coding:utf-8 -*-
from flask import jsonify
from flask import make_response

JSON_RESPONSE_CONTENT_TYPE = 'application/json;charset=UTF-8'

def _custom_response(json_string):

    response = make_response(jsonify(json_string))

    response.headers['Content-Type'] = JSON_RESPONSE_CONTENT_TYPE

    return response

def result_success(data):

    success_dict = {

        "status": "200",

        "msg": "request success",

        "data": data

    }

    return _custom_response(success_dict)

def result_failed(msg, code='400'):

    fail_dict = {

        "status": code,

        "msg": msg,

    }

    return _custom_response(fail_dict)
