Question

我有登录设备的代码。我可以从循环中的设备打印通知。但是我只能从列表中的最后一个设备返回“不打印”数据。如何从循环中的所有设备返回所有数据？

From flask import Flask, jsonify, request

导入netmiko 从netmiko.ssh_autodetect导入SSHDetect 从netmiko.ssh_exception导入NetMikoTimeoutException 导入时间

'app = Flask（名称）

@ app.route（'/ firewall'，Methods = ['GET'，'POST'，'DELETE']）

def防火墙（）：

# Authentication
headers = request.headers
auth = headers.get("xxxxx")
if auth == 'xxxx':

    data = request.get_json(force=True)
    fw_a = data["DeviceAddressList"]
    src_a = data['SourceAddressList']
    src_p = data['SourcePortList']
    dst_a = data['DestinationAddressList']
    dst_p = data['DestinationPortList']
    policy = data["PolicyAllow"]
    p_col = data['Protocol']
    p_show = data['show']
    p_push = data['push']
    config = data['config']

    # Juniper Normalize the data for command line interface
    juniper_command = '"({})"'.format('|'.join(src_a + src_p + dst_a + dst_p))

else:

返回jsonify（{“ message”：“ ERROR：未经授权”}），401

代码示例：遍历ips，获取要为每个ip返回的值，并将其推入dict中。将字典返回给函数“防火墙”的调用者

SecondProperty
