How to print error message on Windows Runtime that is not just the JSON string?

Question

Hello,

I am working on an application using the App42 services on Windows Runtime (Windows 8.1 and Windows Phone 8.1) and I am trying to print error messages in a clean way, but as of right now when I call GetMessage() on the App42Exception object that is passed into the OnException callback it simply returns the message as a JSON string.

Basically is it possible to provide a GetDetails() and a GetMessage() method that only returns those specific parts of the entire exception message instead of returning it formatted as a JSON string?

 

For example when I have an authentication error this is the result of GetMessage():

 

"{\"app42Fault\":{\"httpErrorCode\":404,\"appErrorCode\":2002,\"message\":\"Not Found\",\"details\":\"UserName/Password did not match. Authentication Failed.\"}}"

 

I would like to have a GetMessage() function that just returns "Not Found" and a GetDetails() function that returns "UserName/Password did not match. Authentication Failed" is this possible?

Hello Ferask,

Kindly find the below code snippet to overcome on this issue & let us know if it helps:

 

string messageJSON = exception.GetMessage();

JObject exceptionObj = JObject.Parse(messageJSON);

string details = exceptionObj["app42Fault"]["details"];

 

Thanks,

Hi Himansu,
Thanks for your reply. Above lines you mentioned I kept it like below. There is no GetMessage() while i am pressing e. Also error mark showing on JObject. Do I have to import any module to use this?

public void OnException (Exception e)
{
    result = e.ToString ();
    Debug.Log ("Exception : " + e);
    string messageJSON = e.GetMessage ();
       
    JObject exceptionObj = JObject.Parse (messageJSON);
       
    string details = exceptionObj ["details"];
}

I am using:
using System;
using com.shephertz.app42.paas.sdk.csharp.user;
using com.shephertz.app42.paas.sdk.csharp;
using UnityEngine;
using System.Collections;
using System.Collections.Generic;

am I missing something?

Hello Somnath,

Change your code snippet with below one & let me know if it helps:
public void OnException (Exception e)
{
    result = e.ToString ();
    App42Exception exception = (App42Exception)e;
    Debug.Log ("Exception : " + exception );
    string messageJSON = exception.GetMessage ();
        
    JObject exceptionObj = JObject.Parse (messageJSON);
        
    string details = exceptionObj ["details"];
}

Thanks

Himanshu,
Showing code error in JObject. Its in red color. In unity console showing error
"The type or namespace name `JObject' could not be found. Are you missing a using directive or an assembly reference?"

Got it,
I added SimpleJSON.JObject.and it worked.

public void OnException (Exception e)
{
App42Exception exception = (App42Exception)e;
Debug.Log ("Exception : " + exception);
string messageJSON = exception.GetMessage ();
SimpleJSON.JObject exceptionObj = SimpleJSON.JObject.Parse (messageJSON);
string details = exceptionObj ["details"];
Debug.Log(details);
}

Thanks
