In my Inno setup project, I need to parse a JSON. I Try to create a dll and parse JSON with the dll function but it gives me an access violation error after two days I could not find the reason for this access violation so I decide to parse JSON inside the Inno Setup.
I want to parse this JSON and Use the JsonParser library also here is two similar Questions
but I couldn't get it.
How to parse a JSON string in Inno Setup?
JSON arrays in inno setup
{
"Header":"Install FileType",
"Files":
[
{
"Filename":"SQL Server",
"FileType": 1,
"CheckExists":true,
},
{
"Filename":"Dot Net 3.5",
"FileType": 2,
"CheckExists":false,
}
]
}
I need this function
type
TJFile = record
FileName : string;
FileType : Integer;
CheckExists: Boolean;
GetFile(JSON: string; Index :Integer; var File: TJFile );
how can parse Json to get File with its index. Thank you for help and guid me.
I don't know Pascal Script, so I cannot really answer your question, but I notice that your JSON sample is not valid: there shouldn't be a comma after "true" (line 9), neither after "false" (line 14).

I need to pass a json string as a value to one parameter of a POST request body. My request body looks like this:
"parameter1":"abc",
"parameter2":"def",
"parameter3": "{\"id\":\"\",\"key1\":\"test123\",\"prod1\":{\"id\":\"\",\"key3\":\"test123\",\"key4\":\"12334\",\"key5\":\"3\",\"key6\":\"234334\"},\"prod2\":{\"id\":\"\",\"key7\":\"test234\",\"key8\":1,\"key9\":true}}\"",
"parameter4":false,
"parameter5":"ghi"
}
For parameter3 I need to be pass a string value in json format. The json file is located in my local system and is a huge file, so it would make sense if I can pass it as a jmeter variable. I tried as below:
{
"parameter1":"abc",
"parameter2":"def",
"parameter3": "${jsonObj}",
"parameter4":false,
"parameter5":"ghi"
}
after adding a JSR223 preprocessor with the code below:
import org.apache.jmeter.util.JMeterUtils;
String fileContents = new File("path to json//myJson.json").getText('UTF-8');
vars.put("fileContents",fileContents);
var deltaJson = vars.get("fileContents");
var jsonObj = JSON.parse(deltaJson);
vars.put("jsonObj", JSON.stringify(jsonObj));
But I get below error:
exceptions":{"exceptionType":"System.JSONException","exceptionMessage":"Unexpected character ('$' (code 36)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at input location [1,2]"}
Can anyone help me in resolving this issue?
There is an easier way of doing this, JMeter comes with __FileToString() function so you can achieve the same much faster and without having to do any scripting
Something like:
{
"parameter1": "abc",
"parameter2": "def",
"parameter3": ${__FileToString(path to json//myJson.json,UTF-8,jsonObj)},
"parameter4": false,
"parameter5": "ghi"
}
Also be aware of the following facts:
the recommended language for using in JSR223 Test Elements is Groovy as it provides the maximum performance
you seem to be using JSON object which cannot be used outside of the browser context therefore your code fails to generate proper JSON hence your request fails as you're passing ${jsonObj} as it is, the substitution doesn't happen, you can look to jmeter.log file yourself and see the exact reason of your script failure
I've got this most horrible scenario in where i want to read the files that kinesis firehose creates on our S3.
Kinesis firehose creates files that don't have every json object on a new line, but simply a json object concatenated file.
{"param1":"value1","param2":numericvalue2,"param3":"nested {bracket}"}{"param1":"value1","param2":numericvalue2,"param3":"nested {bracket}"}{"param1":"value1","param2":numericvalue2,"param3":"nested {bracket}"}
Now is this a scenario not supported by normal JSON.parse and i have tried working with following regex: .scan(/({((\".?\":.?)*?)})/)
But the scan only works in scenario's without nested brackets it seems.
Does anybody know an working/better/more elegant way to solve this problem?
The one in the initial anwser is for unquoted jsons which happens some times. this one:
({((\\?\".*?\\?\")*?)})
Works for quoted jsons and unquoted jsons
Besides this improved it a bit, to keep it simpler.. as you can have integer and normal values.. anything within string literals will be ignored due too the double capturing group.

Modify the input to be one large JSON array, then parse that:
input = File.read("input.json")
json = "[#{input.rstrip.gsub(/\}\s*\{/, '},{')}]"
data = JSON.parse(json)
You might want to combine the first two to save some memory:
json = "[#{File.read('input.json').rstrip.gsub(/\}\s*\{/, '},{')}]"
data = JSON.parse(json)
This assumes that } followed by some whitespace followed by { never occurs inside a key or value in your JSON encoded data.
As you concluded in your most recent comment, the put_records_batch in firehose requires you to manually put delimiters in your records to be easily parsed by the consumers. You can add a new line or some special character that is solely used for parsing, % for example, which should never be used in your payload.
Other option would be sending record by record. This would be only viable if your use case does not require high throughput. For that you may loop on every record and load as a stringified data blob. If done in Python, we would have a dictionary "records" having all our json objects.
import json
def send_to_firehose(records):
firehose_client = boto3.client('firehose')
for record in records:
data = json.dumps(record)
firehose_client.put_record(DeliveryStreamName=<your stream>,
Record={
'Data': data
}
)
Firehose by default buffers the data before sending it to your bucket and it should end up with something like this. This will be easy to parse and load in memory in your preferred data structure.
[
{
"metadata": {
"schema_id": "4096"
},
"payload": {
"zaza": 12,
"price": 20,
"message": "Testing sendnig the data in message attribute",
"source": "coming routing to firehose"
}
},

"payload": {

I have the following JSON file.
{
"reviewerID": "ABC1234",
"productID": "ABCDEF",
"reviewText": "GOOD!",
"rating": 5.0,
},
{
"reviewerID": "ABC5678",
"productID": "GFMKDS",
"reviewText": "Not bad!",
"rating": 3.0,
}
I want to parse without SparkSQL and use a JSON parser.
The result of parse that i want is textfile.
ABC1234::ABCDEF::5.0
ABC5678::GFMKDS::3.0
How to parse the json file by using json parser in spark scala?
tl;dr Spark SQL supports JSONs in the format of one JSON per file or per line. If you'd like to parse multi-line JSONs that can appear together in a single file, you'd have to write your own Spark support as it's not currently possible.
A possible solution is to ask the "writer" (the process that writes the files to be nicer and save one JSON per file) that would make your life much sweeter.
If that does not give you much, you'd have to use mapPartitions transformation with your parser and somehow do the parsing yourself.
val input: RDD[String] = // ... load your JSONs here
val jsons = jsonRDD.mapPartitions(json => // ... use your JSON parser here)
i have the following JSON-GET response:
{
"check_lists": [
{
"id": 2,
"name": "Servicebesuch",
"description": ""
}]
}
Problem is the "check_lists" name which i have solved in one of the extract/extractSingle methods of the RESTSerializer so the data is loaded and deserialized successfully to the model named App.Checklist.
Now i got stucked again.
For serialization of my model-data to json, i have to do the same trick reverse but i can not find a hook for that. The serialize Method of the RESTSerializer gets only the pure record and the serialized json, received from this._super... call, does only hold the serialized object and not the call itself.
The server expects a PUT request (in case of updating a list) with the parameter packed in a param named check_list but ember sends it in a param named checklist.
Processing by CheckListsController#update as JSON
Parameters: {"checklist"=>{"name"=>"Kaffeevertrieb", "description"=>""},
"id"=>"3", "check_list"=>{}}
ActionController::ParameterMissing (param is missing or the value is empty: check_list):
Does someone know how to insert the underscore to the json request?
Greetings
I'm trying to extract the parameter roomNo from the following JSON with JMETER XPATH Extractor:
*/
{
"categoryCode": ["I4"],
"Response": {
"class": "example",
"availables": {
"available": [
{
"Desc": " Middle",
"roomNo": "5049"
},
{
"Desc": " Middle",
"roomNo": "5062"
}
],
"class": "test"
},
"advisoryInfo": null
},
"storeId": "10251"
}
*/
i use the following expression with no success:
/Response/availables/available[0]/roomNo
is the expression wrong?
UPDATE:
i'm try to use the plugins JSON PATH EXTRATCTOR. i tryied the following queries with no success:
$...available[0]
$.Response.availables.available..roomNo[0]
$.Response.availables.available[0].roomNo
UPDATE1:
one more consideration: the ajax response I recieve starts with */, is it possible this creates troubles with JSON EXTRACTOR? i see the response through view Results Tree
UPDATE2:
i try the following approach:
ajax request followed by bash extractor, followed by json extractor but it is still not working
in bash extractor i did as suggested using the following strings
String temp = new String(prev.getResponseDataAsString());
prev.setResponseData(temp.replaceAll("\*/","").getBytes());
some more question:
is it possible to see the result of bash extractor?
should i declare before json extractor that it should use temp variable? how?
I'm afraid XPath Extractor won't let you parsing JSON.
You'll need JSONPath Extractor available via JMeter Plugins (you need Extras with Libs Set).
In your case relevant JSONPath query will look like:
$.Response.availables.available..roomNo[0]
Check out Using the XPath Extractor in JMeter guide (scroll down to Parsing JSON) for more information and XPath to JSONPath mappings table.
Hope this helps.
UPD. You can use Beanshell Post Processor to get rid of your */ bits, in that case JSONPath should work fine. Beanshell PostProcessor code:
String temp = new String(prev.getResponseDataAsString());
prev.setResponseData(temp.replaceAll("\\*/","").getBytes());
Make sure that Beanshell Post Processor goes before JSONPath Extractor.
