get values from json request-CodePudding

i have this json response

2022-02-08 14:01:56,048 sdc-web-sockets-pp /moe.com/SMART/logs/srf/srf-web-sockets.log: 2022-02-08 14:01:50,308 srf-web-sockets-pp-1 INFO [null:-1] (executor-thread-19) Op16 - Station : id-00003:vdeURRi8v8evU8AZWEnIwtbrucvjdeZyJL42, MessageId: a8a3e920-88e7-11ec-8f9b-c904565fadef, request message: {"action":"Boot","messageId":"a8d3r920-88e7-11ec-8f9b-c9074d5fadef","type":"CALL","uniqueId":"a8a3e920-88e7-11ec-8f9b-c9074d5fadef","payload":"{"Vendor":"vendorname","PointModel":"pointname","PointSerialNumber":"123456789","firmwareVersion":"1.1.1.8"}"}

I need to get the specific vars.

ex:

vendname=vendorname

model= pointname

modelsn= 123456789

firmversion=1.1.1.8

Can someone help me get these values from the request?

this is what i have so far

def getvalboot(e):
        jsrqs = e.widget.get("1.0", "end-1c")
        if "BOOT" in jsrqs.upper():
            j1,j2ff = jsrqs.split(r"payload")
            j2f = j2ff.replace("\\", "")
            j2a = j2f[3:]
            size = len(j2a)
            j2 = j2a[:size - 2]
            stud_obj = json.loads(j2)
            print("1: ",stud_obj['Vendor'])

Ok, this works but im pretty sure there is a better way to do this, any idea?

CodePudding user response：

You could use the json libary wich comes defualt in built inn with python. The json libary can be used to convert the json file to a dictionary.

import json

f = open(r"file path", "r")
jsonf = f.read()
dict = json.loads(jsonf)
f.close()

CodePudding user response：

It is harder to help when you don't share a bit of code for context.

Assuming we have a context like this:

message = some_api_call()

I would try this:

data = message['payload'] #message is a dictionary and we'd like to access the payload/data

vendname = data['Vendor']
model = data['PointModel']
modelsn = data['PointSerialNumber']
firmversion = data['firmwareVersion']

I don't like the idea of creating a variable for each info, but since it is a small bit of code and we only have one row of data returned, it might not be relevant to discuss that.
