【问题描述】：
我正在尝试从 API 解析一些数据，然后通过 Flask Web 应用程序剥离并仅显示所需的信息。这似乎是我学习的一个很好的用例，构建一个本质上充当 API 接口的 Flask Web 应用程序。
这是我开始使用的脚本：
# !/usr/bin/env python
from __future__ import print_function
from functools import wraps
from flask import Flask, Response, request, jsonify, render_template, Request, json
from flask_bootstrap import Bootstrap
import time
import acos_client as acos
app = Flask(__name__)
app.config['SECRET_KEY'] = 'topsecret!'
bootstrap = Bootstrap(app)
c = acos.Client('1.2.3.4', acos.AXAPI_21, 'admin', 'password')
def get_sl1():
result = {}
sl1 = c.slb.virtual_server.all()
result['x'] = sl1['virtual_server_list'][0]
result['y'] = sl1['virtual_server_list'][0]['vport_list'][0]
return (sl1, result)
@app.route('/', methods=['GET','POST'])
def index():
sl1, sl1_dict = get_sl1()
return render_template('srvlist.html', x=sl1_dict['x'], y=sl1_dict['y'], sl1=sl1)
if __name__ == '__main__':
app.run(host='0.0.0.0', debug=True)
主要是理解我取回并存储为“sl1”的数据：

"stats_data": 1,

}
],
"stats_data": 1
}
]
}
我的 Flask 模板如下所示：
{% extends "bootstrap/base.html" %}
{% import "bootstrap/wtf.html" as wtf %}
{% block title %}A10 Server List{% endblock %}
{% block navbar %}
<nav class="navbar navbar-inverse" role="navigation">
<div class="container">
<a class="navbar-brand" href="{{ url_for('index') }}">A10 Server List</a>
</div>
</nav>
{% endblock %}
{% block content %}
<div class="container">
<div class="row">
<div class="col">
{% for row in x %}
<tr>
<td><b>VIP Name: {{ row['name'] }}</td></b>
<td><b>VIP Address: {{ row['address'] }}</b></td>
</tr><br><BR>
{% endfor %}
{% for row in y %}
<tr>
<td>VPort Name: {{ row['vport_name'] }}</td>
<td>Service Group: {{ row['service_group'] }}</td>
<td>Port: {{ row['port'] }}</td>
</tr><BR>
{% endfor %}
</div>
</div>
</div>
{% endblock %}
我期望得到以下结果：
VIP Name: VS_01 VIP Address: 10.10.10.1
VPort Name: IMAP.SITE.COM_143 Service Group: SG.IMAP.SITE.COM_143 Port: 143
VPort Name: IMAP.SITE.COM_993 Service Group: SG_IMAP.SITE.COM_993 Port: 993
VIP Name: VS_02 VIP Address: 10.10.10.2
VPort Name: LAB_25 Service Group: SG_LAB_25 Port: 25
然而我得到的只是空白：
VIP Name: VIP Address:
VIP Name: VIP Address:
VPort Name: Service Group: Port:
VPort Name: Service Group: Port:
VPort Name: Service Group: Port:
显然，由于各种嵌套的字典列表，我无法正确访问数据。
我认为这应该是相当接近和可行的，只是没有正确解析数据。
任何帮助将不胜感激。
