I have an issue serializing to JSON moving from an IList<"string"> to an IList<"customobject">. The endpoint is expecting an array of strings such as :-
"options": [
"foo1",
"foo2"
]
With the customobject I am getting the following :-
"options": [
{
"name": "foo1"
},
{
"name": "foo2"
}
]
Is there any way to suppress name attribute and continue to get an array of strings with WCF, or do I have to do it another way? Any help would be much appreciated.
Would still appreciate any insight into the possibility of doing this, but for now has been resolved by adding the option as a string as well as an object, and only exporting the string. I know this is duplication, but will have to wait for an update to the endpoint.

I've got json file with some nested objects inside subs in it:
{
"version": 1,
"data": [{
"married": true,
"subs":[
{
"name":{
"sub1":{}
**},**
},
]
},
]}
If I add another 'name' object (with comma as separator), jsonDecode returns nothing.
if there goes single object, without comma - it's ok.
My Json structure is correct, and it's not restricted to use nested objects at all. Please anyone help.
This line has problem **},** and if changed to }, the problem will be solved..
you can check your json by online tools (e.g https://jsonformatter.curiousconcept.com/#)
Is there any way to access properties of an object that was transformed into JSON through the jp (JSON parse) filter of Dust.js?
{
"response": {
"services": [
"{
\"prop1\":\"value1\",
\"prop2\":\"value2\",
\"prop3\":10
}"
]
}
}
For example, with the input above, I intend to receive the following output:
[
{
"prop1": "value1"
}
]
Note that the values inside the service array are strings, and because of that, before accessing the object's properties, I need to run JSON parse filter.
[
{#response.services}
{
"prop1": "{.|jp}"
}{#sep}, {/sep}
{/response.services}
]
What I've developed so far is the code above, and this code is returning the following output:
[
{
"prop1": "[object Object]"
}
]
In short, what I need to do is increment this {.|jp} into something where I can access the properties of the returned object, without adding new filters.
Thanks in advance to everyone who is willing to help!
I am using APIkit in Mule with RAML 0.8 and a JSON schema, as follows (example):
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"properties": {
"cart": {
"title": "",
"description": "",
"type": "object",
"properties": {
"internalNumber": {
"type": "integer"
}
},
"required": [
"internalNumber"
]
}
},
"required": [
"cart"
]
}
and in the Mule Flow, I catch the exception and show the following result:
#[exception.cause.message]
When a validation error occurs, I want to get the name of the field in which the validation failed. Instead, this is what I got:
Input
{
"cart": {
"internalNumber": "I must be an integer"
}
}
Output
"instance type (string) does not match any allowed primitive type (allowed: ["integer"])"
Expected output
{
"field": "cart.internalNumber",
"error": "instance type (string) does not match any allowed primitive type (allowed: ["integer"])"
}
All I want to know is if there is a way to get the name of the field in which the validation errors occurs.
Regarding the Mule Documentation, I can get the whole JSON string but not the name of the failing field...
I hope someone can give me a better solution.
Thanks!
Within your JSON Schema, add "required":"true" attribute, to make the fields mandatory.
You can also use JSON schema validator, in your mule flow, by referring to the updated schema.
Any of the case should through you an error with missing field.
Use below expression to get expected error message.
{
"errorMessage": "#[exception].toString().replace("\"","\\\"")"
}
Not sure if you are expecting it as an output or looking for a way to validate your input and schema.
I can try to suggest on "All I want to know is if there is a way to get the name of the field in wich the validation errors occurs."; to do this better validate your JSON and input data through online validator before defining definitions. Like using http://www.jsonschemavalidator.net/, it will help you with error and fields. Hope this may help!
I have this JSON that is returned from a REST-service I'm using.
{
"id": "6804",
"signatories": [
{
"id": "12125",
"fields": [
{
"type": "standard",
"name": "fstname",
"value": "John"
},
{
"type": "standard",
"name": "sndname",
"value": "Doe"
},
{
"type": "standard",
"name": "email",
"value": "john.doe#somwhere.com"
},
{
"type": "standard",
"name": "sigco",
"value": "Company"
}
]
}
]
}
Currently I'm looking into a way to parse this with json4s, iterating over the "fields" array, to be able to change the property "value" of the different objects in there. So far I've tried a few json libs and ended up with json4s.
Json4s allows me to parse the json into a JObject, which I can try extract the "fields" array
from.
import org.json4s._
import org.json4s.native.JsonMethods._
// parse to JObject
val data = parse(json)
// extract the fields into a map
val fields = data \ "signatories" \ "fields"
// parse back to JSON
println(compact(render(fields)))
I've managed to extract a Map like this, and rendered it back to JSON again. What I can't figure out though is, how to loop through these fields and change the property "value" in them?
I've read the json4s documentation but I'm very new to both Scala and it's syntax so I'm having a difficult time.
The question becomes, how do I iterate over a parsed JSON result, to change the property "value"?
Here's the flow I want to achieve.
Parse JSON into iterable object
Loop through and look for certain "names" and change their value, for example fstname, from John to some other name.
Parse it back to JSON, so I can send the new JSON with the updated values back.
I don't know if this is the best way to do this at all, I'd really appreciate input, maybe there's an easier way to do this.
Thanks in advance,
Best regards,

You can convert the json into an array of case class which is the easiest thing to do. For example: you can have case class for Fields like
case class Field(`type`: String, name: String, value: String)
and you can convert your json into array of fields like read[Array[Field]](json) where json is
[
{
"type": "standard",
"name": "fstname",
"value": "John"
},
...
]
which will give you an array of fields. Similarly, you can model for your entire Json.
As now you have an array of case classes, its pretty simple to iterate the objects and change the value using case classes copy method.
After that, to convert the array of objects into Json, you can simply use write(objects) (read and write functions of Json4s are available in org.json4s.native.Serialization package.
Update
To do it without converting it into case class, you can use transformField function
parse(json).transformField{case JField(x, v) if x == "value" && v == JString("Company")=> JField("value1",JString("Company1"))}
Should be a no brainer, but I'm can't seem to access the elements returned from Newtonsoft's json deserializer.
Example json:
{
"ns0:Test": {
"xmlns:ns0": "http:/someurl",
"RecordCount": "6",
"Record": [{
"aaa": "1",
"bbb": "2",
},
{
"aaa": "1",
"bbb": "2",
}]
}
}
var result = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(somestring);
Stripping out the json up to the Record text, i can access the data without issue.
i.e. result.Recordcount
If i leave the json as shown above, can someone enlighten me how to access Recordcount?
All inputs appreciated. Thanks!
For those JSON properties that have punctuation characters or spaces (such that they cannot be made into valid C# property names), you can use square bracket syntax to access them.
Try this:
int count = result["ns0:Test"].RecordCount;
