Extract Json Data with Python

Question

My Jason Data looks like this:

    {
    "componentId": "SD1:1100047938",
    "componentType": "Device",
    "name": "WR50MS15-7938 (WR 33)",
    "product": "SB 5000TL",
    "productTagId": 9037,
    "pvPower": 886,
    "serial": "1100047938",
    "specWhOutToday": 3.0909803921568626,
    "specWhOutYesterday": 2.924313725490196,
    "state": 307,
    "totWhOutToday": 15764,
    "totWhOutYesterday": 14914
}

How could i only extract:

"state" to a separate file
"pv-power" to a sperate file ?

Thanks !

    url = "https://172.16.63.100/api/v1/overview/Plant:1/devices?todayDate=2022-10-17T12%3A53%3A16.746Z"

payload={}
headers = {
  'Authorization': 'Bearer eyJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE2NjYwMTU0MzMsInN1YiI6Ik1iYWNobCIsInVpZCI6Ijc1YmNkNTM2LTFhOTYtNDQ4My05MjQxLWZkNjY5Zjk3M2Y5OCIsImV4cCI6MTY2NjAxOTAzM30.bMMAsD8iPrAXDp7fbnwYL3Y8lj4Ktok3tU9NHZkYq8s'
}

response = requests.request("GET", url, headers=headers, data=payload, verify=False)

#print(response.text)

data = json.loads(response.text)

with open('data.json', 'w') as f:
    data = json.dump(data, f, indent = 2)

This is my Code for gathering the JSON Data.

I need to exctract the above mentioned Values.

Answer 2

After you run data = json.loads(response.text) , the json is loaded into your data variable as a python dictionary.
So state = data.state and pvPower = data.pvPower should give the info you’re after.

I’m not exactly sure what you want to do with that information, as far as extracting to a separate file. But, json.dump() does output data to a json file.

import requests
import json
import urllib3
import sys
import requests

urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

fehler = '"state": 35'
urltoken = "https://172.16.63.100/api/v1/token"
urldaten = "https://172.16.63.100/api/v1/overview/Plant:1/devices?todayDate=2022-10-17T12%3A53%3A16.746Z"
urlaktuell = "https://172.16.63.100/api/v1/widgets/gauge/power?componentId=Plant%3A1&type=PvProduction"

data = {
    "grant_type": "password",
    "username": "...",
    "password": "...",
}

response = requests.post(urltoken, data, verify=False)

#print(response.json())

data = json.loads(response.text)

with open('/usr/lib/nagios/plugins/check_DataManager/token.txt', 'w') as f:
    data = json.dump(data, f, indent = 2)

with open('/usr/lib/nagios/plugins/check_DataManager/token.txt') as json_file:
    data1 = json.load(json_file)

token = data1["access_token"]

payload={}
headers = {'Authorization': 'Bearer ' + token }

response = requests.request("GET", urldaten, headers=headers, data=payload, verify=False)


data = json.loads(response.text)

with open('/usr/lib/nagios/plugins/check_DataManager/info.txt', 'w') as f:
    data = json.dump(data, f, indent = 2)



if fehler in open('/usr/lib/nagios/plugins/check_DataManager/info.txt').read():
    print("Mindestens ein Wechselrichter hat einen Fehler!")
    exit(1)

else:
    print("Alle Wechselrichter Online!")
    exit(0)


payload={}
headers = {'Authorization': 'Bearer ' + token }

response = requests.request("GET", urlaktuell, headers=headers, data=payload, verify=False)

aktuell = json.loads(response.text)

daten = aktuell["value"]

print("Aktuelle Leistung:", 0.001*daten , "KWh")

I now managed to do all i wanted like this 🙂
Well at first it ignores all Certificate Warnings i have been getting from my SMA Monitoring Device.

Then it gathers the Bearer Access token an stores it into an .txt file

After this is sends a request for json data to urldaten and urlaktuell. This Data is then stored in info.txt and ertrag.txt 🙂 In this Files it checks if there is a faulty Inverter stored 🙂
