I'm new to groovy. I'm trying to split the values in json object in groovy but i cant seem to find a solution. Please find the sample code below
def inputFile = new File("C:\\graph.json")
def InputJSON = new JsonSlurper().parseFile(inputFile,'UTF-8')
InputJSON.each{println it}
def names = InputJSON.graph;
def name
for (int kk=0;kk<4;kk++)
{
name=names.JArray1[kk]
run.put(name.runid, name.rundetails);
println "test::"+name.runid+"--------------"+name.rundetails
}
graph.json
{
"graph": {
"JArray1": [
{
"runid": 1,
"rundetails":{
"01_Home":0.231,
"02_Login":0.561}
}
]
}
}
name.rundetails contains the below values
[01_Home:0.231, 02_Login:0.561]
I would like to split and add it as key and value in Hashmap like below format
Key:01_Home Value:0.231
Key:02_Login Value:0.561
How would i do that any advise on this would be helpful. Thanks in advance.
import groovy.json.*
def inputFile = new StringReader('''
{
"graph": {
"JArray1": [{
"runid": 1,
"rundetails": {
"01_Home": 0.231,
"02_Login": 0.561
}
}
]
}
}
''')
def json = new JsonSlurper().parse(inputFile)
json.graph.JArray1.each{run->
println "runid = ${run.runid}"
// at this point `run.rundetails` is a map like you want
println "details = ${run.rundetails}"
}
As I understand you need collection like:
[[Key:01_Home, Value:0.231], [Key:02_Login, Value:0.561]]
Then you may do:
println InputJSON.graph
.JArray1
.rundetails
.collectEntries{it}
.collect{[Key: it.key, Value: it.value]}

new to groovy and coding in general. Trying to do the following:
(I have looked at many previous Q&As in stackoverflow but none of the solutions I found seem to work)
I have the following JSON from which I need to get a list/string of supplier names i.e. output should be something like : "supplier 1, supplier 2, supplier 3"
[
{
"id":217564,
"created-at":"2020-01-22T08:59:57+00:00",
"state":"submitted",
"supplier":
{
"name":"supplier 1"
}
},
{
"id":217565,
"created-at":"2020-01-22T09:00:00+00:00",
"state":"submitted",
"supplier":
{
"name":"supplier 2"
}
},
{
"id":217566,
"created-at":"2020-01-22T09:00:48+00:00",
"state":"submitted",
"supplier":
{
"name":"supplier 3"
}
}
]
I used the following groovy script to print out all the supplier names in a list:
import groovy.json.*;
#CustomScriptAction(
input = ['json_response'],
output = 'suppliers'
)
def CustomScriptAction14()
{
def object = new JsonSlurper().parseText(json_response.toString())
def suppliers = "No suppliers"
if(object != null && !object.isEmpty())
{
for(def i =0; i<object.size();i++)
{
suppliers = RString.of(object[i].'supplier'.name.toString());
}
}
return suppliers
}
I got the output: "supplier 3"
The issue is that this script is only giving me the last supplier in the loop instead of iterating through the entire loop and printing out all the suppliers. So I tried a different script:
import groovy.json.*;
#CustomScriptAction(
input = ['json_response'],
output = 'suppliers'
)
def CustomScriptAction14()
{
def object = new JsonSlurper().parseText(json_response)
def suppliers = object.findAll { it.value instanceof List }
.values()
.flatten()
.collect { [it.'supplier'.'name'] }
}
return suppliers
But with this I get a blank response.
What am I doing wrong?
Well this ended up working:
import groovy.json.*;
#CustomScriptAction(
input = ['json_response'],
output = 'suppliers'
)
def customScript()
{
def jsonSlurper = new JsonSlurper()
def object = jsonSlurper.parseText(json_response.toString())
suppliers = RString.of(object.'supplier'.'name'.toString())
}
I have a json file containing contact info grouped by city. I want to parse the json and create a list of names and numbers but after fiddling for an hour or so, I can't get this to work in groovy.
def json = '''{
"date":"2018-01-04T22:01:02.2125",
"boston": [
{
"name":"bob",
"phone":"242 123123",
"ext":"12",
"email":"bob#boston.com"
},
{
"name":"alice",
"phone":"212-123-345",
"ext":"1",
"email":"alice#boston.com"
}
],
"chicago": [
{
"name":"charlie",
"phone":"313-232-545",
"ext":"14",
"email":"charlie#chicago.com"
},
{
"name":"denise",
"phone":"414-123-546",
"ext":"9",
"email":"denise#chicago.com"
}
]
}'''
I have tried a few variations on the following theme but they all failed so far.
parsedjson = slurper.parseText(json)
phonelist = []
parsedjson.each{phonelist.add([it['name'],it['phone']])}
It's tricky with the json you have, as you need to look for the values which are lists... You can do this with a findAll, so given the json:
def json = '''{
"date":"2018-01-04T22:01:02.2125",
"boston": [
{
"name":"bob",
"phone":"242 123123",
"ext":"12",
"email":"bob#boston.com"
},
{
"name":"alice",
"phone":"212-123-345",
"ext":"1",
"email":"alice#boston.com"
}
],
"chicago": [
{
"name":"charlie",
"phone":"313-232-545",
"ext":"14",
"email":"charlie#chicago.com"
},
{
"name":"denise",
"phone":"414-123-546",
"ext":"9",
"email":"denise#chicago.com"
}
]
}'''
You can import the JsonSlurper and parse the json as you currently do:
import groovy.json.JsonSlurper
def parsedjson = new JsonSlurper().parseText(json)
Then;
def result = parsedjson.findAll { it.value instanceof List } // Find all entries with a list value
.values() // Get all the lists
.flatten() // Merge them into a single list
.collect { [it.name, it.phone] } // grab the name and phone for each
I am just two days old to groovy, I need to parse a json file with below structure. My actual idea is I need to run a set of jobs in different environments based on different sequences, so I came up with this format of json as a input file to my groovy
{
"services": [{
"UI-Service": [{
"file-location": "/in/my/server/location",
"script-names": "daily-batch,weekly-batch,bi-weekly-batch",
"seq1": "daily-batch,weekly-batch",
"seq2": "daily-batch,weekly-batch,bi-weekly-batch",
"DEST-ENVT_seq1": ["DEV1", "DEV2", "QA1", "QA2"],
"DEST-ENVT_seq2": ["DEV3", "DEV4", "QA3", "QA4"]
}]
}, {
"Mobile-Service": [{
"file-location": "/in/my/server/location",
"script-names": "daily-batch,weekly-batch,bi-weekly-batch",
"seq1": "daily-batch,weekly-batch",
"seq2": "daily-batch,weekly-batch,bi-weekly-batch",
"DEST-ENVT_seq1": ["DEV1", "DEV2", "QA1", "QA2"],
"DEST-ENVT_seq2": ["DEV3", "DEV4", "QA3", "QA4"]
}]
}]
}
I tried below script for parsing the json
def jsonSlurper = new JsonSlurper()
//def reader = new BufferedReader(new InputStreamReader(new FileInputStream("in/my/location/config.json"),"UTF-8"))
//def data = jsonSlurper.parse(reader)
File file = new File("in/my/location/config.json")
def data = jsonSlurper.parse(file)
try{
Map jsonResult = (Map) data;
Map compService = (Map) jsonResult.get("services");
String name = (String) compService.get("UI-Service");
assert name.equals("file-location");
}catch (E){
println Exception
}
I need to first read all the services (UI-service, Mobile-Service, etc..) then their elements and their value
Or you could do something like:
new JsonSlurper().parseText(jsonTxt).services*.each { serviceName, elements ->
println serviceName
elements*.each { name, value ->
println " $name = $value"
}
}
But it depends what you want (and you don't really explain in the question)
Example for reading from JsonParser object:
def data = jsonSlurper.parse(file)
data.services.each{
def serviceName = it.keySet()
println "**** key:${serviceName} ******"
it.each{ k, v ->
println "element name: ${k}, element value: ${v}"
}
}
other options:
println data.services[0].get("UI-Service")["file-location"]
println data.services[1].get("Mobile-Service").seq1
I am quite new to Groovy and I am parsing a JSON file with following code:
void getItemData()
{
def jsonSlurper = new JsonSlurper()
def reader = new BufferedReader(new InputStreamReader(new FileInputStream("data.json"),"UTF-8"));
data = jsonSlurper.parse(reader);
data.TESTS.each{println it.MEMBER_ID}
}
And I am getting printed properly the value of MEMBER_ID.
I want to Parameterize the above function like:
void getItemData(String item)
{
...
}
so that I can call this function with the desired item I want. For example: I want the MEMBER_ADDRESS. I want to call the function like:
getItemData("MEMBER_ADDRESS")
Now How I should change the statement:
data.TESTS.each{println it.MEMBER_ID}
I tried with
it.${item}
and some other ways not working.
Please teach me how to do it.
My JSON file is like below:
{
"TESTS":
[
{
"MEMBER_ID": "my name",
"MEMBER_ADDRESS": "foobarbaz",
}
]
}
Those here from google, looking for an answer to parse JSON File.
void getItemData(String item) {
def jsonSlurper = new JsonSlurper()
def data = jsonSlurper.parseText(new File("data.json").text)
println data.TESTS.each{ println it["$item"] }
}
getItemData("MEMBER_ADDRESS")
You need to add quotes around ${item} like:
import groovy.json.*
void getItemData(String item) {
def jsonSlurper = new JsonSlurper()
def reader = new BufferedReader(new InputStreamReader(new FileInputStream("/tmp/json"),"UTF-8"))
data = jsonSlurper.parse(reader)
data.TESTS.each { println it."$item" }
}
getItemData("MEMBER_ADDRESS")
I have been experimenting with the groovy Jsonbuilder as you can see below trying to look at different ways to build JSON objects and arrays. After things started to make sense, I tried expanding to what is shown below. The question I have is, why does "content" show up in the json pretty string output? I actually have another json object displaying this.class information in json string outputs.
Any ideas? I'm new to this, so it could definitely be an obvious one.
def tt = ["test", "test1"]
def jjj = "jason"
def js3 = new groovy.json.JsonBuilder()
def js2 = new groovy.json.JsonBuilder(tt);
js3 hello: "$jjj", "$jjj": tt
def js4 = new groovy.json.JsonBuilder()
def result = js4([sdn: js3, openflow: js2, type: 3])
println js4.toPrettyString();
outputs:
{
"sdn": {
"content": {
"hello": "jason",
"jason": [
"test",
"test1"
]
}
},
"openflow": {
"content": [
"test",
"test1"
]
},
"type": 3
}
The problem can be restated as...
why does this:
import groovy.json.*
def js3 = new JsonBuilder(["test", "test1"])
def js4 = new JsonBuilder(js3)
println js4.toString()
print:
{"content":["test","test1"]}
and this:
import groovy.json.*
def js3 = new JsonBuilder(["test", "test1"])
def js4 = new JsonBuilder(js3.content)
println js4.toString()
prints this (?) :
["test","test1"]
The short answer is that JsonBuilder has a member named content, which represents the payload. When one JsonBuilder absorbs another, we want to replace the payload, and not nest it. This line is the way to replace the payload:
def js4 = new JsonBuilder(js3.content)
Ultimately, this stems from the fact that JsonBuilder.toString() (code here) calls JsonOutput.toJson(object) (code here).
An exercise for the reader is to experiment with:
class MyBuilder {
def content
}
def myB = new MyBuilder(content: ["test", "test1"])
println JsonOutput.toJson(myB)
println JsonOutput.toJson(myB.content)
