I have below response from an API get call.
How do i read the value of dummyId and testcontactId. Below is the sample response:
{
"pageCount":1,
"pageIndex":0,
"pageSize":200,
"totalCount":1,
"dto":{
"data":[
{
"callDuration":"0:00:07",
"dummyId":20,
"testcontactId":"3002",
"id":54
}
],
"columns":[
{
"fieldName":"test1",
"displayName":"test Id",
"show":true,
"sortable":true,
"fieldType":"string",
"order":1
}
]
}
}
I can't place a comment to ask what language you're using, Here is how you'd do it in JavaScript
Parse your API Result to a Object with var data = JSON.parse() JSON.parse()
Then you can just go data.dto.data[0].dummyId
Since dto.data is an array, You can just use the indexes to access each option.
if you need to find specific values, You might want to take a look at Array.find
In the future, Please add a tag with your programming language and things you've tried.

I am trying to get data using GDC portal api. As it is shown in GDC API, to send an HTTP GET request, we need to have a format similar to:
https://api.gdc.cancer.gov/files?filters=%7B%22op%22%3A%22and%22%2C%22content%22%3A%5B%7B%22op%22%3A%22in%22%2C%22content%22%3A%7B%22field%22%3A%22cases.submitter_id%22%2C%22value%22%3A%5B%22TCGA-CK-4948%22%2C%22TCGA-D1-A17N%22%2C%22TCGA-4V-A9QX%22%2C%22TCGA-4V-A9QM%22%5D%7D%7D%2C%7B%22op%22%3A%22%3D%22%2C%22content%22%3A%7B%22field%22%3A%22files.data_type%22%2C%22value%22%3A%22Gene%20Expression%20Quantification%22%7D%7D%5D%7D&format=tsv&fields=file_id,file_name,cases.submitter_id,cases.case_id,data_category,data_type,cases.samples.tumor_descriptor,cases.samples.tissue_type,cases.samples.sample_type,cases.samples.submitter_id,cases.samples.sample_id,analysis.workflow_type,cases.project.project_id,cases.samples.portions.analytes.aliquots.aliquot_id,cases.samples.portions.analytes.aliquots.submitter_id&size=1000
Which is a format from json payload as:
{
"filters":{
"op":"and",
"content":[
{
"op":"in",
"content":{
"field":"cases.submitter_id",
"value":[
"TCGA-CK-4948",
"TCGA-D1-A17N",
"TCGA-4V-A9QX",
"TCGA-4V-A9QM"
]
}
},
{
"op":"=",
"content":{
"field":"files.data_type",
"value":"Gene Expression Quantification"
}
}
]
},
"format":"tsv",
"fields":"file_id,file_name,cases.submitter_id,cases.case_id,data_category,data_type,cases.samples.tumor_descriptor,cases.samples.tissue_type,cases.samples.sample_type,cases.samples.submitter_id,cases.samples.sample_id,analysis.workflow_type,cases.project.project_id,cases.samples.portions.analytes.aliquots.aliquot_id,cases.samples.portions.analytes.aliquots.submitter_id",
"size":"1000"
}
I wanna add more fields to the payload json and get the equivalent http query string format. I have tried some online convertors, like: JSON-to-String Convertor. Copying the above JSON gives me the below result:
"{\"filters\":{\"op\":\"and\",\"content\":[{\"op\":\"in\",\"content\":{\"field\":\"cases.submitter_id\",\"value\":[\"TCGA-CK-4948\",\"TCGA-D1-A17N\",\"TCGA-4V-A9QX\",\"TCGA-4V-A9QM\"]}},{\"op\":\"=\",\"content\":{\"field\":\"files.data_type\",\"value\":\"Gene Expression Quantification\"}}]},\"format\":\"tsv\",\"fields\":\"file_id,file_name,cases.submitter_id,cases.case_id,data_category,data_type,cases.samples.tumor_descriptor,cases.samples.tissue_type,cases.samples.sample_type,cases.samples.submitter_id,cases.samples.sample_id,analysis.workflow_type,cases.project.project_id,cases.samples.portions.analytes.aliquots.aliquot_id,cases.samples.portions.analytes.aliquots.submitter_id\",\"size\":\"1000\"}"
So, I tried to get data using the generated string by adding
https://api.gdc.cancer.gov/files?
to the beginning of that. But, running this, gives me a different output. So, how can I convert the JSON to exactly what is given in GDC website? Sorry, I am very new to API and their usages.
just want to know if and how I can parse a HTTP response with a dynamic name in a JSON?
I used the Azure Management API to receive the managed identities (system- and user assigned managed identities) to receive all managed identities.
With a foreach I am iterating the results.
If a resource has a system assigned managed identity and user assigned managed identity, the response looks like this:
{
"principalId": "<principalId1>",
"tenantId": "<tenantId>",
"type": "SystemAssigned, UserAssigned",
"userAssignedIdentities": {
"/subscriptions/<subscriptionId>/resourcegroups/<resourceGroupName>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<userAssignedIdentitiesName>": {
"principalId": "<principalId2>",
"clientId": "<clientId>"
}
}
}
Now, I would like to get the <principalId2>.
Unfortunately, the Name of the object is dynamic related to the scope of the resource /subscriptions/<subscriptionId>/resourcegroups/<resourceGroupName>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<userAssignedIdentitiesName>.
How can I parse the JSON to receive the needed <principalId2>?
For all other responses I can easily use the Data operations Parse JSON with the payload I inserted from the HTTP response.
Is there a way to use a wildcard? Otherwise, could I somehow just select the first object of userAssignedIdentities to receive the needed value?
Ok, this should work for you. This is the flow I tested with ...
Initialise JSON
Your JSON as a string, how you do that in your solution may differ slightly.
Initialize XPath Result
Defined as an Array and the expression is ...
xpath(xml(json(concat('{ root: ', replace(variables('JSON'), 'PrincipalId', 'principalId'), '}'))), '(//principalId)[2]')
Initialize Result
A bit more work again but defined as a String and the expression is ...
array(xpath(xml(base64ToString(variables('XPath Result')[0]?['$content'])), '//text()'))[0]
The end result should be your value ...
i'm currently trying to set up some JMeter testplans. I am pretty new to this (started a week ago) and don't have much programming experience either, so i hope you could help me in this case.
I already set up some http requests and have some simple JSON Extractor post processors to save some of the variables and use them with the "${variable}" notation.
But now i need to save and modify an object from a response to use that in the next http request.
My respose is a extremely big JSON object and the part im interested in looks something like this:
{
"payload": {
"workspace": {
"resultInstance": [
[{"part": "1"...}],
[{"part": "2"...}],
...
[{"part": "20"...}]
]
}
}
}
Note that for whatever reason these objects {"part":"1"...} are inside a nested array. And they are also pretty big.
I would like to safe those objects in a variable to use them in my next http request which should looks like this:
{
"instanceChange": {
"functionChecks": [
{"part": "1"...},
{"part": "2"...},
...
{"part": "20"...}
]
}
}
So what im really trying to find is a way to save all of the possible objects inside the nested array "resultInstance" and put them inside the non nested array "functionChecks".
I already looked inside the JMeter documentation but because of my poor programming background i cant find a way to realize this.
I think i need something like the JSR223 PostProcessor and "simply go through the resultInstance-array and use smth. like an getObject() on these", but i cant figure out the code i need and if its even possible to safe objects in variables in Jmeter.
Im pretty thankful for every bit of help or advice :).
Thanks in advance,
aiksn
Add JSR223 PostProcessor as a child of the request which returns the JSON response
Put the following code into "Script" area:
def response = new groovy.json.JsonSlurper().parse(prev.getResponseData())
def request = ['instanceChange': ['functionChecks': response.payload.workspace.resultInstance]]
vars.put('request', new groovy.json.JsonBuilder(request).toPrettyString())
That's it, you should be able to refer the generated request body as ${request} where required
More information:

let response ={
"payload": {
"workspace": {
"resultInstance": [
[{"part": "1"...}],
[{"part": "2"...}],
...
[{"part": "20"...}]
]
}
}
};
let requestObj={
"instanceChange": {
"functionChecks": [
]
}
};
response.payload.workspace.resultInstance.forEach(myFunction);
myFunction(item, index) {
requestObj.instance.functionsCheck.push(item[0]);
}
I'm trying to authenticate RADIUS Requests against a RESTful API (provided by Customer) using rlm_rest.
The problem I am facing is that
response JSON format (of REST API provided by Customer), is different from rlm_rest default format (indicated in etc/raddb/mods-enabled/rest).
My Virtual Server configuration as below:
Default
authorize {
...
...
rest
if (ok) {
update control {
Auth-Type := rest
}
}
}
mods-enabled/rest
authorize {
uri = "https://3rd-party-API/auth"
method = 'post'
body = 'json'
chunk = 0
tls = ${..tls}
data = '{
"code": 1,
"identifier": %I,
"avps": {
"User-Name": ["%{User-Name}"],
"NAS-IP-Address": ["%{NAS-IP-Address}"],
"Called-Station-Id": ["%{Called-Station-Id}"],
"Calling-Station-Id": ["%{Calling-Station-Id}"],
"NAS-Identifier": ["%{NAS-Identifier}"]
}
}'
}
Result
/sbin/radiusd -Xxx
HTTP response code
200
JSON Body
{
"code": "2",
"identifier": "91",
"avps": {
"Customer-Attributes": "Hello"
...
...
"Acct-Interim-Interval": "300"
}
}
The JSON structure is different from the example, and xlat parse
"code"
"identifier"
"avps"
And, of course, xlat finds no attributes match with the dictionary, while it cannot find "avps" and won't dig deeper.
So I was wondering is there anyway to either
Define the response JSON structure for xlat to parsing
Insert a "is_json" or "do_xlat" flag into the JSON ("avps"), and hope xlat will then dig deeper
Save the JSON and parse with exec/rlm_exec (using JQ or any other bash/JSON tools)
Please advise if there is any workaround. Thanks!
In FreeRADIUS version 4, there's a rlm_json module, which implements a custom node query language based on xpath (jpath), it is extremely limited and only supports some very basic queries (feel free to enhance it via PR :) ).
Below is an example I pulled out of my library of customer configurations. You can see here it's pulling out two keys (externalID and macAddress) from the root level of the JSON doc and assigning them to a couple of custom attributes (Subscriber-ID and Provisioned-MAC).
map json "%{rest_api:https://${modules.rest[rest_api].server}/admin/api/${modules.rest[rest_api].api_key}/external/getDeviceBySerialNumber?certificateSerialNumber=%{lpad:&TLS-Client-Cert-Serial 40 0}}" {
&Subscriber-ID := '$.externalId'
&Provisioned-MAC := '$.macAddress'
}
The xlat expansion can also be modified to send HTTP body data. Just put a space after the URL and pass your custom JSON blob.
Trying to figuring out how to deserialize this kind of json in talend components :
{
"ryan#toofr.com": {
"confidence":119,"email":"ryan#toofr.com","default":20
},
"rbuckley#toofr.com": {
"confidence":20,"email":"rbuckley#toofr.com","default":15
},
"ryan.buckley#toofr.com": {
"confidence":18,"email":"ryan.buckley#toofr.com","default":16
},
"ryanbuckley#toofr.com": {
"confidence":17,"email":"ryanbuckley#toofr.com","default":17
},
"ryan_buckley#toofr.com": {
"confidence":16,"email":"ryan_buckley#toofr.com","default":18
},
"ryan-buckley#toofr.com": {
"confidence":15,"email":"ryan-buckley#toofr.com","default":19
},
"ryanb#toofr.com": {
"confidence":14,"email":"ryanb#toofr.com","default":14
},
"buckley#toofr.com": {
"confidence":13,"email":"buckley#toofr.com","default":13
}
}
This JSON comes from the Toofr API where documentation can be found here .
Here the actual sitation :
For each line retreived in the database, I call the API and I got this (the first name, the last name and the company change everytime.
Does anyone know how to modify the tExtractJSONField (or use smthing else) to show the results in tLogRow (for each line in the database) ?
Thank you in advance !
EDIT 1:
Here's my tExtractJSONfields :
When using tExtractJSONFields with XPath, you need
1) a valid XPath loop point
2) valid XPath mapping to your structure relative to the loop path
Also, when using XPath with Talend, every value needs a key. The key cannot change if you want to loop over it. Meaning this is invalid:
{
"ryan#toofr.com": {
"confidence":119,"email":"ryan#toofr.com","default":20
},
"rbuckley#toofr.com": {
"confidence":20,"email":"rbuckley#toofr.com","default":15
},
but this structure would be valid:
{
"contact": {
"confidence":119,"email":"ryan#toofr.com","default":20
},
"contact": {
"confidence":20,"email":"rbuckley#toofr.com","default":15
},
So with the correct data the loop point might be /contact.
Then the mapping for Confidence would be confidence (the name from the JSON), the mapping for Email would be email and vice versa for default.
EDIT
JSONPath has a few disadvantages, one of them being you cannot go higher up in the hierarchy. You can try finding out the correct query with jsonpath.com
The loop expression could be $.*. I am not sure if that will satisfy your need, though - it has been a while since I've been using JSONPath in Talend because of the downsides.
I have been ingesting some complex json structures and did this via minimal json libraries, and tjava components within talend.
