Question

我有一个简单的烧瓶应用程序运行，在用户输入后发布一些数据。目前，它在json.dump字典中显示此数据，但我试图让它显示如下：

Name:     yyy
Shack:    yyy
Status:   yyy
Payments: vvv

我已经看到了一些与jsonify和其他json方法有关的问题，但我似乎无法让它们发挥作用。代码：

from flask import Flask, request, Response, render_template
import json
import sys
import numpy as np

app = Flask(__name__)

app.config['DEBUG'] = True

path = '/home/username/ishack/'
if path not in sys.path:
    sys.path.append(path)

client_db = np.genfromtxt('/home/username/ishack/client_db.csv', delimiter=',', dtype=None, names=True)



@app.route('/')
def form():
    return render_template('form_page.html')


@app.route('/address', methods=['POST'])
def display_info():
    address = request.form['address']
    ind = np.where(client_db['Shack'] == address)[0]
    res = {'Name': client_db[ind]['Name'][0],
            'Shack': client_db[ind]['Shack'][0],
            'Status': client_db[ind]['Status'][0],
            'Payments': client_db[ind]['Payments'][0]}
    return Response(json.dumps(res), mimetype='application/json')


if __name__ == '__main__':
    app.run(host="0.0.0.0", port=5000)

更改响应以呈现具有所需格式的页面。您无法对纯JSON响应进行样式化。

@app.route('/address', methods=['POST'])
def display_info():
    address = request.form['address']
    ind = np.where(client_db['Shack'] == address)[0]
    res = {'Name': client_db[ind]['Name'][0],
            'Shack': client_db[ind]['Shack'][0],
            'Status': client_db[ind]['Status'][0],
            'Payments': client_db[ind]['Payments'][0]}
    return render_template("address_page.html", address=res)

<强> address_page.html ：

<table>
{% for key,value in address.items() %}
    <tr>
        <td>{{key}}:</td><td>{{value}}</td>
    </tr>
{% endfor %}
</table>

在pythonanywhere中显示flask json数据
