from flask import jsonify

@app.route("/index")
def index():
    data = {"name":"zeng", "age":23}
    return jsonify(data)

import json

@app.route("/index")
def index():
    data = {"name":"zeng", "age":23}
    json_str = json.dumps(data)
    return json, 200, {"Content-Type": "application/json"}

import json

@app.route("/index")
def index():
    data = {"name":"zeng", "age":23}
    json_str = json.dumps(data)
    resp = make_response(json_str)
    resp.headers["Content-Type"] = "application/json"
    return resp
