so i have this data which is outputted from stringify(doc)
{
"id": "8467fdae-c38c-4b6e-9492-807d7c9eb97e",
"message": "send to nodejs"
}
but im not sure how can i go ahead in getting a single value from it, e.g message. Any help would be appreciated as ive tried different methods and they seem to not be working
After you use stringify method the value you have is string.
So You can not get single property from it, except you convert it become object again and get property it. Like this:
object = {
"id": "8467fdae-c38c-4b6e-9492-807d7c9eb97e",
"message": "send to nodejs"
};
// JSON string is value which you get after use Stringify method
jsonString = JSON.stringify(object);
// Convert jsonString to object again and get message property
message = JSON.parse(jsonString).message
stringify() will convert json to string.
Before running stringify(), doc is already json and you can get message by doc.message.
after running stringify(), the result will be string, if you want to get json back, you can use JSON.parse()

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 know there are multiple similar topics, however trying their solutions doesn't give me expected result.
Input json string
data:"{"message": "{\"type\":\"CONTROL\",\"command\":\"REQUEST_STATUS_ALL\"}"}"
object declaration/parse:
const msg: Message = <Message>JSON.parse(data.data);
output:
{message: "{"type":"CONTROL","command":"REQUEST_STATUS_ALL"}"}
-values are not properly assigned, but instead in a text form.
the same object looks like this if it's initialized manually(in TS):
Message {type: "CONTROL", status: undefined, command: "REQUEST_STATUS_ALL", body: undefined}
What is the correct way to parse that json string into the Message object?
Thank you!
It seems the value for message was improperly encoded as a string. Calling JSON.parse a second time on the message property will get the result you want, though you might want to fix the underlying cause of the improperly encoded data instead.
parseMessage(data: string) {
const msgTemp = JSON.parse(data);
msgTemp.message = JSON.parse(msgTemp.message);
return <Message>msgTemp;
}
const msg = parseMessage(data.data);
I have a JSON object returned in my console, and I want to display those data named "offers".
the JSON object is returned like that :
I tried to display my JSON Object data with :
console.log(JSON.stringify(data));
The thing is, it says that "data is not defined"
Does anyone know what happens ? :)
You should add full path to element of json, for example if your json looks like:
var json = {"par":22, "par2":555, "elems":[{"attr1":53, "attr2":99}] };
and if you want to get attr1 value, you should do something like this:
console.log(json.elems[0].attr1); // 53
so in your case that could be something like:
variableName.result.data.offers //variableName is variable that your "consoling"
Method JSON.stringify doesn't get yout specified value from JSON structure, it's converts JSON object to string.
console.dir provides a good representation of object than console.log().U can try with both
console.log(result.data.offers[0]);
console.dir(result.data.offers[0]);
I want to store the result from a call to a Domino Access Service (DAS) in a localStorage however when I try to convert the result object to a JSON string I get an error.
With DAS you get the result as an Array e.g.:
[
{
"#entryid":"1-CD90722966A36D758025725800726168",
"#noteid":"16B46",
Does anyone know how I get rid of the square brackets or convert the Array quickly to a JSON object?
Here is a snippet of my code:
var REST = "./myREST.xsp/notesView";
$.getJSON(REST,function(data){
if(localStorage){
localStorage.setItem('myCatalog',JSON.stringify(data));
}
});
Brackets are part of the JSON syntax. They indicate that this is an array of objects. And as you point to a view it is very likely that you would get more than one object back (one for each entry in the view).
So if you are only interested in the first element you could do this:
var REST = "./myREST.xsp/notesView";
$.getJSON(REST,function(data){
if(localStorage){
var firstRecord = data[0] || {};
localStorage.setItem('myCatalog',JSON.stringify(firstRecord));
}
});
Otherwise, you would need to define a loop to handle each of the objects :-)

I have a document on a mongodb on Heroku. Each object in the document has a system generated object id in the form of
"_id": {
"$oid": "xxxxxxxxxxxxxxxxxxxxxxxx"
}
When I make a query and get the response from the server, I stringify the response using JSON.stringify and I log the object on the server console. When I do this the following gets logged:
this is the response: [{"creator":"al","what[place]":"home","what[time [start]":"22:00","what[time][end]":"","what[details]":"","who[]":["joe","kay","mau"],"_id":"xxxxxxxxxxxxxxxxxxxxxxxx"}]
Right after the full object gets logged, I try to log the id to make sure I can access it... I want to then pass the id to a different object so that I can have a reference to the logged object.
I have this right now:
var stringyfied = JSON.stringify(res);
console.log("this is the response: " + stringyfied);
console.log("id: " + stringyfied._id);
but when the item is logged I get
id: undefined
instead of
id: "xxxxxxxxxxxxxxxxxxxxxxxx"
No matter how I try to access the _id property, I keep getting undefined even though it get printed with the console.log for the full object
I've tried:
stringyfied.id
stringyfied["_id"]
stringyfied["id"]
stringyfied._id.$oid
stringyfied.$oid
you need to use JSON.parse(), cause JSON.stringify() is to convert to string, parse is to get the object. stringifiedid is a string
What is being returned is an array with one object in it.
The way to access the _id is with stringyfied[0]._id. However, it would be cleaner to pull the object out of the array instead.
There are a few ways you can do that. If this query will only ever return one result and that's all you'll want, you can use the findOne method instead. If the query may return more than a single document, then you will want to loop through the returned results.
I also agree with #dariogriffo that you'll need to use JSON.parse() on the stringified JSON variable.
