Karate -- JSON Response Parsing - json

Below is the JSON response I receive when I am hitting a particular web service:
[
{
"sId" : "0001",
"sName" : "abc1",
"sPlace" : "abc11"
}, {
"sId" : "0002",
"sName" : "abc2",
"sPlace" : "abc12"
}, {
"sId" : "0003",
"sName" : "abc3",
"sPlace" : "abc13"
}, {
"sId" : "0004",
"sName" : "abc4",
"sPlace" : "abc14"
}
]
I don't know which index has my expected values (I need to validate multiple values after identifying which has sId == '0003'), this is dynamic. Don't want to user hard coded value.
And match response.[3].sId == '0003'
because this will be changed next time.
I have two questions regarding this:
How can I pass response to java code and get the array index which having sId == '0003' so that I can use this index to validate?
How can I pass a variable value as an array index in response?
The code below is not working.
def ind = Java.type('karate.Utility.FindIndex')
response.['#ind'].sId == '0003'

karate uses json-path which allows writing conditions to read data from JSON.
example:
* def sId = "0003"
* def sValue = karate.jsonPath(response, "$[?(#.sId == '" + sId + "')]")
* match sValue[0] == {"sId" : "0003","sName" : "abc3","sPlace" : "abc13"}
now if there is a match in sId on the response JSON array, all such matches will be returned.
No need to do * match sValue[0].sId == "0003" as this is your filter
criteria

Groovy: json get value of id based on child value

I have a json as below:
[
{
"id":6619137,
"oid":"6fykq37gm60x",
"key":{
"key":"6619137"
},
"name":"Prod",
"planKey":{
"key":"PDP"
},
"environments":[
{
"id":6225923,
"key":{
"key":"6619137-6225923"
},
"name":"Production",
"deploymentProjectId":6619137,
}
],
},
{
"id":6619138,
"oid":"6fykq37gm60y",
"key":{
"key":"6619138"
},
"name":"QA",
"planKey":{
"key":"QDP"
},
"environments":[
{
"id":6225924,
"key":{
"key":"6619138-6225924"
},
"name":"QA",
"deploymentProjectId":6619138,
}
],
},
]
I can use the below code to extract the value of id and environments.id based on the name value. projectID will give 6619137 and environmentID will give 6225923
def e = json.planKey.find{it.name=='Prod'}
def projectID = e.id
def environmentID = e.environments[0].id
However, when I try to extract the value of id and environments.id based on the plankey.key value (e.g. PDP or QDP), using the same format above returns me an error of java.lang.NullPointerException: Cannot get property 'id' on null object at Script60.run(Script60.groovy:52)
def e = json.planKey.find{it.planKey=='{key=PDP}'}
def projectID = e.id
def environmentID = e.environments[0].id
Is there a way I can get the projectID with the plankey key value?
Think of your JSON object as a key/value map with multiple levels. There is no such item as
json.find{it.planKey=='{key=PDP}'}
However, you can find with values at any level, like this:
def e = json.find{it.planKey.key == "PDP"}
If you have a structure where planKey may not exist, or it doesn't always have key, that's a bit different, but from your question it sounds like that's not the case here.
EDIT: correcting syntax based on comment below.

Is there a way to randomize the jsonPath array number in get[] myJson?

I have a list of values that I can use for the title field in my json request. I would like to store a function in the common.feature file which randomizes the title value when a scenario is executed.
I have attempted using the random number function provided on the commonly needed utilities tab on the readme. I have generated a random number successfully, the next step would be using that randomly gernerated number within the jsonpath line in order to retrieve a value from my data list which is in json.
* def myJson =
"""
{
"title" : {
"type" : "string",
"enum" : [
"MR",
"MRS",
"MS",
"MISS"
[...]
]
}
}
"""
* def randomNumber = random(3)
* def title = get[0] myJson.title.enum
* print title```
The code above works but I would like to randomize the number within the get[0]. How is this possible in Karate?
I'm not sure of what you want, but can't you just replace 0 by randomNumber in get[randomNumber] myJson.title.enum ?

Retrieving dictionary keys with pre-fixed parent keys using python

I am trying to list all keys with parent keys from a dictionary using python 3. How can I achieve this goal?
Here is so far I did using a recursive function (so that I can use this with any depth of dictionaries).
Here, if I do not use header_prefix, I get all the keys without parent keys. However, when I use header_prefix, it keeps adding parent keys incorrectly to the keys. Basically, I cannot reset header_prefix in the appropriate location.
from pprint import pprint
#%%
data = {
"AWSTemplateFormatVersion": "2010-09-09" ,
"Description": "Stack for MyProject 01",
"Resources": {
"elb01": {
"Type": "AWS::ElasticLoadBalancing::LoadBalancer",
"Properties": {
"CrossZone" : "false",
"HealthCheck" : {
"Target" : "TCP:80",
"Interval" : "20"
},
"ConnectionSettings": {
"IdleTimeout": "120"
}
}
},
"lc01": {
"Type": "AWS::AutoScaling::LaunchConfiguration" ,
"Properties": {
"ImageId" : "ami-01010105" ,
"InstanceType" : "t2.medium"
}
},
"asg01": {
"Type" : "AWS::AutoScaling::AutoScalingGroup",
"Properties" : {
"HealthCheckGracePeriod" : 300,
"HealthCheckType" : "EC2"
}
}
}
}
pprint(data)
#%%
def get_headers(json_data, headers, header_prefix):
for key, value in json_data.items():
if type(value) == dict:
header_prefix = header_prefix + key + '.'
get_headers(value,headers,header_prefix)
else:
headers.append(header_prefix+key)
return(headers)
#%%
header_list = []
prefix = ''
data_headers = get_headers(data, header_list, prefix)
pprint(data_headers)
From the above code, I get the following output:
['AWSTemplateFormatVersion',
'Description',
'Resources.elb01.Type',
'Resources.elb01.Properties.CrossZone',
'Resources.elb01.Properties.HealthCheck.Target',
'Resources.elb01.Properties.HealthCheck.Interval',
'Resources.elb01.Properties.HealthCheck.ConnectionSettings.IdleTimeout',
'Resources.elb01.lc01.Type',
'Resources.elb01.lc01.Properties.ImageId',
'Resources.elb01.lc01.Properties.InstanceType',
'Resources.elb01.lc01.asg01.Type',
'Resources.elb01.lc01.asg01.Properties.HealthCheckGracePeriod',
'Resources.elb01.lc01.asg01.Properties.HealthCheckType']
My expected output is like below:
['AWSTemplateFormatVersion',
'Description',
'Resources.elb01.Type',
'Resources.elb01.Properties.CrossZone',
'Resources.elb01.Properties.HealthCheck.Target',
'Resources.elb01.Properties.HealthCheck.Interval',
'Resources.elb01.Properties.ConnectionSettings.IdleTimeout',
'Resources.lc01.Type',
'Resources.lc01.Properties.ImageId',
'Resources.lc01.Properties.InstanceType',
'Resources.asg01.Type',
'Resources.asg01.Properties.HealthCheckGracePeriod',
'Resources.asg01.Properties.HealthCheckType']
It seems to be a scoping issue. When you modify header_prefix inside the if statement, it modifies it in the function scope and so for all iterations of the loop, leading to the incorrect version being passed to get_headers in later iterations of the loop
In short:
Change
header_prefix = header_prefix + key + '.'
get_headers(value,headers,header_prefix)
To
pfx = header_prefix + key + '.'
get_headers(value,headers,pfx)
This way a new local variable will be created and passed, rather than the header_prefix being updated within the function scope.
(any variable name that's not used within the get_headers function will do

How to get sum of nested JSON elements in Long format using scala and play?

I have nested JSON like -
"disks" : [ {
"name" : "v2.16",
"diskAggregate" : "aggr0",
"diskRPM" : 15000,
"totalSizeBytes" : 1077477376,
"vendorId" : "NETAPP ",
"usedBytes" : 1070071808,
"diskType" : "FCAL",
"uuid" : "4E455441:50502020:56442D31:3030304D:422D465A:2D353230:32353836:30303030:00000000:00000000",
"portName" : "FC:A ",
"raidGroup" : "rg0"
},
{
"name" : "v4.16",
"diskAggregate" : "aggr0",
"diskRPM" : 15000,
"totalSizeBytes" : 1077477376,
"vendorId" : "NETAPP ",
"usedBytes" : 1070071808,
"diskType" : "FCAL",
"uuid" : "4E455441:50502020:56442D31:3030304D:422D465A:2D353230:32353633:34333030:00000000:00000000",
"portName" : "FC:B ",
"raidGroup" : "rg0"
}]
I want to get addition 'totalSizeBytes' from above list of objects.
I used following code to get it -
val storageDevices = "above given json".toList
val totalCapacity = storageDevices.foldLeft(0) {
case (sumOfAllDevices, storageDevice) =>
val sumOfTotalBytesOnStorageDevice = storageDevice.disks.foldLeft(0) {
case (totalBytesOnDevice, disk) =>
totalBytesOnDevice + disk.usedBytes.getOrElse(0).toString.toInt
}
sumOfAllDevices + sumOfTotalBytesOnStorageDevice
// Logger.info("dss"+sumOfTotalBytesOnStorageDevice.toString.toInt)
}
This code gives me total capacity in Integer format. But as there are too many objects in disks array, the totalCapacity will get exceed int. So I wanted to convert it to Long while doing addition.
I want following output-
"totalCapacity": [
{
"name": "192.168.20.22",
"y": 123456789
}
]
How do I convert it to Long to get exact sum of all 'totalBytesAvailable' from array/list???
Cast zero values as 0L (by default assumed Int), both in foldLeft(0L) and in getOrElse(0L), so the compiler will enforce arithmetic additions on Long.

Query json data on MongoDB

I have a rather complex structure on my json and I cannot find how to query it to get the rows I am interested in. Here is a sample of my data:
{
"_id" : ObjectId("5282bf9ce4b05216ca1b68f8"),
"authorID" : ObjectId("5282a8c3e4b0d7f4f4d07b9a"),
"blogID" : "7180831558698033600",
"blogs" : {
"$" : {
"posts" : [
[
{
"author" : {
"displayName" : "mms",
...
...
...
}}}
So, I am interested in finding all json entries that have the author displayName equal to "mms".
My collection name is bz so, a find all query would be: db.dz.find()
What criteria do I have to put inside the find() to only get json document with author displayName equal to mms?
Any ideas?
Thank you in advance!
Suppose you have replaced field name "$" with "dollarSign".
Then db.dz.find({"blogs.dollarSign.posts.author.displayName": "mms"}) will fetch whole documents according to your requirements.
