I am trying to extract a specific part of the JSON but I keep on getting errors.
I am interested in the following sections:
"field": "tag",
"value": "Wian",
I can extract the entire filter section using:
for i in range(0,values_num):
dedata[i]['filter']
But if I try to filter beyond that point I just get errors.
Could someone please assist me with this?
Here is the JSON output style:
{
"mod_time": 1594631137499,
"description": "",
"id": 82,
"name": "Wian",
"include_custom_devices": true,
"dynamic": true,
"field": null,
"value": null,
"filter": {
"rules": [
{
"field": "tag",
"operand": {
"value": "Wian",
"is_regex": false
},
"operator": "~"
}
],
"operator": "and"
}
}
You are probably trying to access the data in rules but since its an array, you have to specifically access that array by getting the [0] index.
You could simplistically just use .get('<name>') as shown below:
dedata['filter']['rules'][0].get('field'))
Likewise for value:
dedata[i]['filter']['rules'][0]['operand'].get('value')
comment out the for loop and try without it and [i] and see if it works

I am being returned information from an API that I would like to access in Python. I would like to access the "position" element. I have tried the following code to no avail:
"position": response['response'][0]['id'],
This seems to give me either a key Error or an Attribute Error. Can anyone give me some help with this?
You should do this instead:
position = response["response"][0][0]["position"]
print(position) # 1
In a program I am working on, I use ArcCloud's music fingerprinting service. after uploading the data I need identified, I am given back this piece of data:
re = ACRCloudRecognizer(config)
data = (re.recognize_by_file('audio_name.mp3', 0))
>>>data
'{"metadata":{"timestamp_utc":"2020-05-18 23:00:59","music":[{"label":"NoCopyrightSounds","play_offset_ms":125620,"duration_ms":326609,"external_ids":{},"artists":[{"name":"Culture Code & Regoton"}],"result_from":1,"acrid":"a53ea40c6a8b4a6795ac3d799f6a4aec","title":"Waking Up","genres":[{"name":"Electro"}],"album":{"name":"Waking Up"},"score":100,"external_metadata":{},"release_date":"2014-05-25"}]},"cost_time":5.5099999904633,"status":{"msg":"Success","version":"1.0","code":0},"result_type":0}\n'
I think it's a list, but I am unable to figure out how to navigate nor grab specific information from it. I'm unsure how they set up the information, and what patterns to look for. Ideally, I would like to create a print function that would print the title, artists, and album.
Any help is much appreciated!
Formatting the JSON makes it more legible

Looks like you're looking for .metadata.music.title (presumably), but only if .status.code is 0
First of all, I am not getting a proper error reponse on the web platform as well (https://jsonschemalint.com). I am using jsonschema in python, and have a proper json schema and json data that works.
The problem I'd like to solve is the following: Before we deliver JSON files with example data, we need to run them through SoapUI to test if they are proper, as we are dealing with huge files and usually our devs may make some errors in generating them, so we do the final check.
I'd like to create a script to automate this, avoiding SoapUI. So after googling, I came across jsonschema, and tried to use it. I get all the proper results,etc, I get errors when I delete certain elements as usual, but the biggest issues are the following:
Example :
I have a subsubsub object in my JSON schema, let's call it Test1, which contains the following :
**Schema**
{
"exname":"2",
"info":{},
"consumes":{},
"produces":{},
"schemes":{},
"tags":{},
"parameters":{},
"paths":{},
"definitions":{
"MainTest1":{
"description":"",
"minProperties":1,
"properties":{
"test1":{
"items":{
"$ref":"#//Test1"
},
"maxItems":10,
"minItems":1,
"type":"array"
},
"test2":{
"items":{
"$ref":"#//"
},
"maxItems":10,
"minItems":1,
"type":"array"
}
}
},
"Test1":{
"description":"test1des",
"minProperties":1,
"properties":{
"prop1":{
"description":"prop1des",
"example":"prop1exam",
"maxLength":10,
"minLength":2,
"type":"string"
},
"prop2":{
"description":"prop2des",
"example":"prop2example",
"maxLength":200,
"minLength":2,
"type":"string"
},
"prop3":{
"enum":[
"enum1",
"enum2",
"enum3"
],
"example":"enum1",
"type":"string"
}
},
"required":[
"prop3"
],
"type":"object"
}
}
}
**Proper example for Test1**
{
"Test1": [{
"prop1": "TestStr",
"prop2": "Test and Test",
"prop3": "enum1"
}]
}
**Improper example that still passes validation for Test1**
{
"test1": [{
"prop1": "TestStr123456", [wrong as it passes the max limit]
"prop2": "Test and Test",
"prop3": " enum1" [wrong as it has a whitespace char before enum1]
}]
}
The first issue I ran across is that enum in prop3 isn't validated correctly. So, when I use " enum1" or "enumruwehrqweur" or "literally anything", the tests pass. In addition, that min-max characters do not get checked throughout my JSON. No matter how many characters I use in any field, I do not get an error. Anyone has any idea how to fix this, or has anyone found a better workaround to do what I would like to do? Thank you in advance!
There were a few issues with your schema. I'll address each of them.
In your schema, you have "Test1". In your JSON instance, you have "test1". Case is important. I would guess this is just an error in creating your example.
In your schema, you have "Test1" at the root level. Because this is not a schema key word, it is ignored, and has no effect on validation. You need to nest it inside a "properties" object, as you have done elsewhere.
{
"properties": {
"test1": {
Your validation would still not work correctly. If you want to validate each item in an array, you need to use the items keyword.
{
"properties": {
"test1": {
"items": {
"description": "test1des",
Finally, you'll need to nest the required and type key words inside the items object.
Here's the complete schema:
{
"properties": {
"test1": {
"items": {
"description": "test1des",
"minProperties": 1,
"properties": {
"prop1": {
"description": "prop1des",
"example": "prop1exam",
"maxLength": 10,
"minLength": 2,
"type": "string"
},
"prop2": {
"description": "prop2des",
"example": "prop2example",
"maxLength": 200,
"minLength": 2,
"type": "string"
},
"prop3": {
"enum": [
"enum1",
"enum2",
"enum3"
],
"example": "enum1",
"type": "string"
}
},
"required": [
"prop3"
],
"type": "object"
}
}
}
}
I've a nested json structure, I'm using objectpath (python API version), but I don't understand how to select and filter some information (more precisely the nested information in the structure).
EG.
I want to select the "description" of the action "reading" for the user "John".
JSON:
{
"user":
{
"actions":
[
{
"name": "reading",
"description": "blablabla"
}
]
"name": "John"
}
}
CODE:
$.user[#.name is 'John' and #.actions.name is 'reading'].actions.description
but it doesn't work (empty set but in my JSON it isn't so).
Any suggestion?
Is this what you are trying to do?
import objectpath
data = {
"user": {
"actions": {
"name": "reading",
"description": "blablabla"
},
"name": "John"
}
}
tree = objectpath.Tree(data)
result = tree.execute("$.user[#.name is 'John'].actions[#.name is 'reading'].description")
for entry in result:
print entry
Output
blablabla
I had to fix your JSON. Also, tree.execute returns a generator. You could replace the for loop with print result.next(), but the for loop seemed more clear.
import objectpath import *
your_json = {"name": "felix", "last_name": "diaz"}
# This json path will bring all the key-values of your json
your_json_path='$.*'
my_key_values = Tree(your_json).execute(your_json_path)
# If you want to retrieve the name node...then specify it.
my_name= Tree(your_json).execute('$.name')
# If you want to retrieve a the last_name node...then specify it.
last_name= Tree(your_json).execute('$.last_name')
I believe you're just missing a comma in JSON:
{
"user":
{
"actions": [
{
"name": "reading",
"description": "blablabla"
}
],
"name": "John"
}
}
Assuming there is only one "John", with only one "reading" activity, the following query works:
$.user[#.name is 'John'].actions[0][#.name is 'reading'][0].description
If there could be multiple "John"s, with multiple "reading" activities, the following query will almost work:
$.user.*[#.name is 'John'].actions..*[#.name is 'reading'].description
I say almost because the use of .. will be problematic if there are other nested dictionaries with "name" and "description" entries, such as
{
"user": {
"actions": [
{
"name": "reading",
"description": "blablabla",
"nested": {
"name": "reading",
"description": "broken"
}
}
],
"name": "John"
}
}
To get a correct query, there is an open issue to correctly implement queries into arrays: https://github.com/adriank/ObjectPath/issues/60
I have a json file with the following example json entry:
{
"title": "Test prod",
"leafPage": true,
"type": "product",
"product": {
"title": "test product",
"offerPrice": "$19.95",
"offerPriceDetails": {
"amount": 19.95,
"text": "$19.95",
"symbol": "$"
},
"media": [
{
"link": "http://www.test.com/cool.jpg",
"primary": true,
"type": "image",
"xpath": "/html[1]/body[1]/div[1]/div[3]/div[2]/div[1]/div[1]/div[1]/div[1]/a[1]/img[1]"
}
],
"availability": true
},
"human_language": "en",
"url": "http://www.test.com"
}
I can post via python script this to my test server perfectly when I use:
"text": entry.get("title"),
"url": entry.get("url"),
"type": entry.get("type"),
However I cannot get the following nested item to upload the values, how do I structure the python json call to get a nested python json entry?
Ive tried the below without success, I need to have it as .get because there are different fields currently in the json file and it errors out without the .get call.
"Amount": entry.get("product"("offerPrice"))
Any help on how to structure the nested json entry would be very much appreciated.
You need to do:
"Amount": entry.get("product", {}).get("offerPrice")
entry.get("product", {}) returns a product dictionary (or an empty dictionary if there is no product key).
