Python json响应中的访问字段

我试图从一个API请求中提取一个特定字段，稍后我将在另一个任务中使用该字段。基本上需要自动化这个请求，这样我才能跟上远程机器的时间戳

我可以使用我创建的脚本获取json列表：

from datetime import datetime
from requests.auth import HTTPBasicAuth
import requests
import json

response = requests.get("https://$hostname/api/profiler/1.13/reporting/timestamps.json", verify=False, auth=HTTPBasicAuth("$username", "$password"))

time = response.json()

print(json.dumps(time, indent=4, sort_keys=True))

以下是回应：

[
    {
        "data_resolution": "min",
        "datasource": "TRAFFIC",
        "end_time": 1591793520,
        "start_time": 0
    },
    {
        "data_resolution": "day",
        "datasource": "TRAFFIC",
        "end_time": 1591743600,
        "start_time": 0
    },
    {
        "data_resolution": "15mins",
        "datasource": "SERVICE",
        "end_time": 1591793100,

        "datasource": "TRAFFIC",
        "end_time": 1591793520,
        "start_time": 0
    },

        "data_resolution": "5mins",
        "datasource": "TRAFFIC",
        "end_time": 1591793400,

        "start_time": 0
    },
    {
        "data_resolution": "hour",
        "datasource": "TRAFFIC",
        "end_time": 1591790400,

        "datasource": "TRAFFIC",
        "end_time": 1591793100,
        "start_time": 0
    },
    {
        "data_resolution": "min",
        "datasource": "FDS_TRAFFIC",
        "end_time": 1591793520,
        "start_time": 1587220140
    },
    {
        "data_resolution": "5mins",
        "datasource": "FDS_TRAFFIC",
        "end_time": 1591793400,
        "start_time": 1587219900
    },
    {
        "data_resolution": "hour",
        "datasource": "FDS_TRAFFIC",
        "end_time": 1591790400,
        "start_time": 1587218400
    }
]

我需要提取这个精确的字段（特别是结束时间字段）：

我似乎无法提取该字段。

解决方案是迭代json响应：

list

之后：

time=response.json（）

试试这个：

[i['end_time'] for i in time if i['data_resolution']=='flow' and i['datasource']=='TRAFFIC']

谢谢各位，我就是这样做的。谢谢@Doc

from datetime import datetime
from requests.auth import HTTPBasicAuth
import requests
import json

response = requests.get("https://10.65.170.112/api/profiler/1.13/reporting/timestamps.json", verify=False, auth=HTTPBasicAuth("admin", "admin"))

time = response.json()


**for t in time:
    end_time = (time[3]["end_time"])**


print(end_time)

为了解决这个问题，您对

json

做了哪些研究？您得到的json是一个列表，因此python列表的所有逻辑都适用。因此，第一个条目是时间[0]，最后一个条目是时间[-1]。您可以使用

在时间中为t:

迭代所有值。对于第一个条目的

end\u time

，您有

time[0]['end\u time']

。您可以迭代所有条目Quick noob question，这也会给我值吗？使用带有用户名的@symbol，如@AlexandreAmaralBednell，向用户发送消息。还有，我不明白你的问题。解释一下。

[i['end_time'] for i in time if i['data_resolution']=='flow' and i['datasource']=='TRAFFIC']

from datetime import datetime
from requests.auth import HTTPBasicAuth
import requests
import json

response = requests.get("https://10.65.170.112/api/profiler/1.13/reporting/timestamps.json", verify=False, auth=HTTPBasicAuth("admin", "admin"))

time = response.json()


**for t in time:
    end_time = (time[3]["end_time"])**


print(end_time)
