I am working with a python library for a certain api service. And in order to connect to their account, they use the json file.
This is how the API connection looks like.
api = VoximplantAPI('credentials.json')
credentials.json
{
"account_email": "my email",
"account_id": "ac_id",
"key_id": "key_id",
"private_key": "private"
}
I removed the values.
I have a question, how can I add dynamic variables to json so that I can take values from Django settings, for example using Jinja. I have been looking for an answer for several hours, but I have not found an answer.
Json in python is technically Dictionary, so you can update the same way you update dictionary
For example,
a = {"a": 123}
b = {"b": 456}
And by writing a.update(b) you will get in response
{"a": 123, "b": 456}
The same way loop through all the data you wan to add in json
For example,
final_json = {
"account_email": "my email",
"account_id": "ac_id",
"key_id": "key_id",
"private_key": "private"
}
users = User.objects.filter(name="test")
temp_dict = {}
count = 1
for user in users:
temp_dict.update({f"first_name{count}": user.first_name})
count += 1
And then update your final_json by
final_json.update(temp_dict)
You will get your json as:
{
"account_email": "my email",
"account_id": "ac_id",
"key_id": "key_id",
"private_key": "private",
"first_name1": "value_1",
"first_name2": "value_2",
..

This question already has answers here:
Azure Function - Python - ServiceBus Output Binding - Setting Custom Properties
(2 answers)
Closed 8 months ago.
I'm using an Azure Function (Python) to send a message to a Service Bus topic whenever a file lands in blob storage following a similar set up to that outlined here.
In particular, in order to send the message I have this in the JSON file:
{
"type": "serviceBus",
"direction": "out",
"connection": "AzureServiceBusConnectionString",
"name": "msg",
"queueName": "outqueue"
}
and in init.py file I have msg.set(input_msg) where input_msg is a JSON string, the output of doing json.dumps(list(reader)) on a CSV string.
When this message is picked up by the topic and subscriptions it has content type set to text/plain, whilst I'd like this to be application/json as mentioned here.
Is there a way to set this, for instance when I do msg.set, is there a way to specify the content type?
Full code:
init.py
def get_json_content_from_csv(csv_content: str) -> str:
reader = csv.DictReader(io.StringIO(csv_content))
json_content = json.dumps(list(reader))
return json_content
def main(event: func.EventGridEvent, msg: func.Out[str]):
data = event.get_json()
url = data["url"]
input_blob = BlobClient.from_blob_url(url, DefaultAzureCredential())
csv_content = input_blob.download_blob(encoding='UTF-8').readall()
json_content = get_json_content_from_csv(csv_content)
msg.set(json.dumps(json_content))
function.json
{
"bindings": [
{
"type": "eventGridTrigger",
"name": "event",
"direction": "in"
},
{
"type": "serviceBus",
"direction": "out",
"connection": "AzureServiceBus",
"name": "msg",
"topicName": "dev-iris-service-bus-topic"
}
]
}
According to this github issue for the Python SDK:
Cannot set Service Bus Message ContentType - Github Issue
The github issue response points to the docs here to set the contentType property on the message class

I have below JSON response coming from API, in which 104 and 2 are dynamically changing and I have these values already set in environmental varibales, e.g. {location_id} = 2, {account_id} = 104
Can anyone help on how to parse JSON and get the location object based on environment variable value for location id in postman tests section
{
"104": {
"2": [
{
"FirstName": "John",
"LastName": "McClain",
"Phone": "1234567890"
}
],
"3": [
{
"FirstName": "Rita",
"LastName": "Maria",
"Phone": "3092432345"
}
]
}
}
This is a very horrible and flaky way to 'test' the values from the response JSON in the question. This assumes that the environment vars that were set in the previous request were account_id = 104 and location_id = 3. This does a hardcoded check to see that the FirstName property in that object, equals 'Rita'.
pm.test('Get the values', () => {
var jsonData = pm.response.json()[pm.environment.get('account_id')][pm.environment.get('location_id')]
pm.expect(jsonData[0].FirstName).to.equal('Rita')
})
It's difficult to tell what you actually want to do with the data and this test isn't something that I would use but if you just wanted an insight into how you would parse the data based on some environment vars this is at least a starting point.
If more information is provided, I will update my answer to reflect this.
I have a following Json data to post.
{
"id": 1,
"name": "Zypher",
"price": 12.50,
"tags": [{
"tag": 1,
"tagName": "X"
},
{
"tag": 2,
"tagName": "Y"
},
{
"tag": 2,
"tagName": "Z"
}]
}
My Jmeter Test Plan is as following,
- Test Plan
- Thread Group
- Http Request Defaults
- Http Cookie Manager
- Simple Controller
- CSV Data Set Config (Sheet_1)
- Http Header Manager
- Http Request (The hard coded json was provided here as body data)
Every thing works fine. Now I want to use csv to parametrised my Json.
Sheet_1:
id,name,price
1,Zypher,12.50
I modified json with these 3 parameters and its works for me. Now I want to parametrise detail portion. I have no idea how to do this.
All I want to keep my json like this,
{
"id": ${id},
"name": ${name},
"price": ${price},
"tags": [
{
"tag": ${tag},
"tagName": ${tagName}
}]
}
How could I dynamically make json array tags for details portion from csv data? I want it to be looped as row provided in csv file.
Updated csv
id,name,price,tag,tagname
1,Zypher,12.50,7|9|11,X|Y|Z
It would be great in this format
id,name,price,tag
1,Zypher,12.50,7:X|9:Y|11:Z
tag has two properties dividing by :
You can do it using JSR223 PreProcessor and Groovy language, something like:
Given you have the following CSV file structure:
id,name,price,tag
1,Zypher,12.50,X|Y|Z
And the following CSV Data Set Config settings:
Add JSR223 PreProcessor as a child of the HTTP Request sampler and put the following code into "Script" area:
import groovy.json.JsonBuilder
def json = new JsonBuilder()
def tagsValues = vars.get("tags").split("\\|")
class Tag {int tag; String tagName }
List<Tag> tagsList = new ArrayList<>()
def counter = 1
tagsValues.each {
tagsList.add(new Tag(tag: counter, tagName: it))
counter++
}
json {
id Integer.parseInt(vars.get("id"))
name vars.get("name")
price Double.parseDouble(vars.get("price"))
tags tagsList.collect { tag ->
["tag" : tag.tag,
"tagName": tag.tagName]
}
}
sampler.addNonEncodedArgument("",json.toPrettyString(),"")
sampler.setPostBodyRaw(true)
Remove any hard-coded data from the HTTP Request sampler "Body Data" tab (it should be absolutely blank)
Run your request - JSON payload should be populated dynamically by the Groovy code:
References:
Parsing and producing JSON - Groovy
Groovy Is the New Black
Update:
for CSV format
id,name,price,tag
1,Zypher,12.50,7:X|9:Y|11:Z
Replace the below Groovy code:
List<Tag> tagsList = new ArrayList<>()
def counter = 1
tagsValues.each {
tagsList.add(new Tag(tag: counter, tagName: it))
counter++
}
with
List<Tag> tagsList = new ArrayList<>();
tagsValues.each {
String[] tag = it.split("\\:")
tagsList.add(new Tag(tag: Integer.parseInt(tag[0]), tagName: tag[1]))
}
I'm trying to pull JSON from a Yahoo API to get the conversion rate of USD to SEK. However, I can't seem to get the JSON converted to a Hash, it shows "query" as being the only key since JSON comes in as one string.
The JSON request returns:
{"query":{"count":1,"created":"2016-12-04T13:06:00Z","lang":"en-us","results":{"rate":{"id":"USDSEK","Name":"USD/SEK","Rate":"9.1900","Date":"12/2/2016","Time":"9:59pm","Ask":"9.2000","Bid":"9.1900"}}}}
My code is as follow:
require 'net/http'
require 'json'
url = 'https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.xchange%20where%20pair%20in%20(%22USDSEK%22)&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback='
uri = URI(url)
response = Net::HTTP.get(uri)
json_hash= JSON.parse(response)
puts json_hash["Rate"]
the puts statement returns 'nil'
I've tried following an example from this site, however I do not yield the same results based on the way my data is being brought as his is being statically entered.
*Note I am not using 'ostruct', trying simply with json.
Thank you for any insight.
As you can see, the field you are looking for is into an inner hash. Try
puts json_hash["query"]["results"]["rate"]["Rate"]
Have you check the structure of your json?
{
"query": {
"count": 1,
"created": "2016-12-04T13:06:00Z",
"lang": "en-us",
"results": {
"rate": {
"id": "USDSEK",
"Name": "USD/SEK",
"Rate": "9.1900",
"Date": "12/2/2016",
"Time": "9:59pm",
"Ask": "9.2000",
"Bid": "9.1900"
}
}
}
}
To fetch the rate key you should do something like:
json_hash["query"]["results"]["rate"]
Compare that with json above to understand your problem.
I am building python backend for SPA (Angular) using MongoDB.
Here is what I use: Python 3.4, MongoDB 3, Flask, flask-mongoengine and flask-restful
Now I receive the following JSON from my backend:
[
{
"_id": {
"$oid": "55c737029380f82fbf52eec3"
},
"created_at": {
"$date": 1439129906376
},
"desc": "Description.....",
"title": "This is title"
},
etc...
]
And I want to receive something like that:
[
{
"_id": "55c737029380f82fbf52eec3",
"created_at": 1439129906376,
"desc": "Description.....",
"title": "This is title"
},
etc...
]
My code for now:
from flask import json
from vinnie import app
from flask_restful import Resource, Api
from vinnie.models.movie import Movie
api = Api(app)
class Movies(Resource):
def get(self):
movies = json.loads(Movie.objects().all().to_json())
return movies
api.add_resource(Movies, '/movies')
Model:
import datetime
from vinnie import db
class Movie(db.Document):
created_at = db.DateTimeField(default=datetime.datetime.now, required=True)
title = db.StringField(max_length=255, required=True)
desc = db.StringField(required=True)
def __unicode__(self):
return self.title
What is the best way to format convenient JSON for front-end?
If you are confident you want to get rid of all the similar cases, then you can certainly write code that matches that pattern. For example:
info = [
{
"_id": {
"$oid": "55c737029380f82fbf52eec3"
},
"created_at": {
"$date": 1439129906376
},
"desc": "Description.....",
"title": "This is title"
},
#etc...
]
def fix_array(info):
''' Change out dict items in the following case:
- dict value is another dict
- the sub-dictionary only has one entry
- the key in the subdictionary starts with '$'
In this specific case, one level of indirection
is removed, and the dict value is replaced with
the sub-dict value.
'''
for item in info:
for key, value in item.items():
if not isinstance(value, dict) or len(value) != 1:
continue
(subkey, subvalue), = value.items()
if not subkey.startswith('$'):
continue
item[key] = subvalue
fix_array(info)
print(info)
This will return this:
[{'title': 'This is title', 'created_at': 1439129906376, 'desc': 'Description.....', '_id': '55c737029380f82fbf52eec3'}]
Obviously, reformatting that with JSON is trivial.
I found a neat solution to my problem in flask-restful extension which I use.
It provides fields module.
Flask-RESTful provides an easy way to control what data you actually render in your response. With the fields module, you can use whatever objects (ORM models/custom classes/etc.) you want in your resource. fields also lets you format and filter the response so you don’t have to worry about exposing internal data structures.
It’s also very clear when looking at your code what data will be rendered and how it will be formatted.
Example:
from flask_restful import Resource, fields, marshal_with
resource_fields = {
'name': fields.String,
'address': fields.String,
'date_updated': fields.DateTime(dt_format='rfc822'),
}
class Todo(Resource):
#marshal_with(resource_fields, envelope='resource')
def get(self, **kwargs):
return db_get_todo() # Some function that queries the db
