Python 获取JSON数据的特定值

我使用以下代码从RESTCONF HTTPS请求中获取JSON数据

https_request = 'https://' + host + '/restconf/data/' + operation
headers = {'Content-type': 'application/yang-data+json', 'Accept': 'application/yang-data+json'}
r = requests.get(https_request, auth=(user, password), headers=headers, verify=False)
print r.json()

我得到的数据是：

{
    "Cisco-IOS-XE-native:Tunnel": {
        "name": 0,
        "bandwidth": {
            "kilobits": 256
        },
        "ip": {
            "address": {
                "primary": {
                    "address": "10.10.1.1",
                    "mask": "255.255.255.252"
                }
            }
        },
        "load-interval": 30,
        "Cisco-IOS-XE-tunnel:tunnel": {
            "source": "GigabitEthernet1",
            "destination": {
                "ipaddress-or-host": "10.2.1.3"
            }
        }
    }
}

基本上，我希望函数返回字段的

“带宽”

值，即

256

。我尝试了以下方法，但没有成功

capacity = r.json()['Cisco-IOS-XE-native:Tunnel']['bandwidth']

试试这个：

j={
    "Cisco-IOS-XE-native:Tunnel": {
        "name": 0,
        "bandwidth": {
            "kilobits": 256
        },
        "ip": {
            "address": {
                "primary": {
                    "address": "10.10.1.1",
                    "mask": "255.255.255.252"
                }
            }
        },
        "load-interval": 30,
        "Cisco-IOS-XE-tunnel:tunnel": {
            "source": "GigabitEthernet1",
            "destination": {
                "ipaddress-or-host": "10.2.1.3"
            }
        }
    }
}
print(j['Cisco-IOS-XE-native:Tunnel']['bandwidth'])

这将返回：

{'kilobits': 256}

对于256：

print(j['Cisco-IOS-XE-native:Tunnel']['bandwidth']['kilobits'])

---

r.json（）['Cisco-IOS-XE-native:Tunnel']['bandwidth']['kilobits']

？当你说“它没有工作”时，你能更具体一点吗？例如，描述您的期望以及它抛出的异常将更有帮助。在您的情况下，您没有检索到确切的所需密钥。@knh190我忘记添加

['kilobits']

值。有了你的回答，它成功了！谢谢！
