python flask开发网页中文显示异常解决

from flask import Flask, jsonify
import json
import config
from flask import Response

app = Flask(__name__)

#配合@app.route("/")，进行请求结束时执行操作的装饰器 也可以实现中文显示
@app.after_request
def after_request(response):
    if response.content_type == 'application/json':
        response.data = json.dumps(json.loads(response.data.decode('utf-8')), ensure_ascii=False)
        response.content_type = 'application/json;charset=utf-8'
    return response

@app.route("/")
def index():
    data = {
        'key': '这是一个中文测试项'
    }
    return jsonify(data)

#after_request 作用到index函数，后续/2 、/3路径的测试不需要after_request 装饰器即可

#强制转化 ok 强制json.dumps转化可以
@app.route('/2')
def get_user2():
    data = {"code": 404, "msg": "用户不存在"}
    return Response(
        json.dumps(data, ensure_ascii=False),
        mimetype='application/json; charset=utf-8'
    )

#not OK，手动添加response.headers["Content-Type"]  不起作用

@app.route('/3')
def get_user3():

    response = jsonify({"code": 404, "msg": "用户不存在"})
    response.headers["Content-Type"] = "application/json; charset=utf-8"

    return response

if __name__ == '__main__':

    app.run(debug=True,port=5006)
