我正在尝试获取开关接口的最后输入时间并通过 flask 将其发布到 html 但即使我设法获得了列表，我也无法将其推送到 html。
我的错误是什么？
import logging
from netmiko import ConnectHandler
from contextlib import redirect_stdout
from flask import Flask, render_template
import logging
app = Flask(__name__)
@app.route('/')
# Enable debug logging for Netmiko and write to a file
def index():
logging.basicConfig(filename='netmiko.log', level=logging.DEBUG)
device = {
'device_type':'cisco_ios_telnet',
'ip': '10.10.20.250',
'username': 'admin',
'password': 'cisco',
'port':23,
}
with ConnectHandler(**device) as net_connect:
# Enter enable mode
net_connect.enable()
# Send "show interfaces" command and get output
show_output = net_connect.send_command('show interfaces')
net_connect.disconnect()
interfaces_list = []
for line in show_output.splitlines():
if line.startswith('Gigabit'):
# extract the interface name
interface_name = line.split()[0]
# extract the last input time
if line.startswith(' Last input '):
last_input_time = line.split(' Last input ')[1].split(',')[0]
interfaces_list.append(f"{interface_name} - Last input {last_input_time}")
else:
continue
return render_template('index.html', interfaces=interfaces_list)
if __name__ == '__main__':
app.run(debug=True)
这是我的 html 代码（在模板下保存为 index.html）
<!DOCTYPE html>
<html>
<head>
<title>Show Interfaces</title>
</head>
<body>
<table>
<thead>
<tr>
<th>Interface</th>
<th>Last Input</th>
</tr>
</thead>
<tbody>
{% for interface in interfaces %}
<tr>
<td>{{ interface.interface }}</td>
<td>{{ interface.last_input }}</td>
</tr>
{% endfor %}
</tbody>
</table>
</body>
</html>
对于那些不知道show interfaces的输出是什么的人，我会给你这个例子
