Unable to parse JSON response (yesterday I was)

[SteMMo33]

Hi there,
I'm developing a C# app by vs2022.
I installed RestSharp by NuGet --> version 111.1.0
Some JSON replies that until yesterday was parsed, now they are not. (???)

The request is (contains two requests ..):

			var client = InitRest();
			var request = new RestRequest("GetTornei.php", Method.Get);

			List<Torneo> list = new List<Torneo>();
			try
			{
				var list2 = client.GetJson<TorneiQuery>("GetTornei.php");

				var response = client.ExecuteGet<TorneiQuery>(request);
				Debug.WriteLine(response.Content);
				Debug.WriteLine(response.StatusCode);
				if (response.StatusCode == HttpStatusCode.OK)
				{
					//list = response.Data.list;
				}

				statusCode = response.StatusCode;

The class is:

namespace TorneoSB
{
	public class Torneo
	{
		// I membri devono essere 'proprietà' per consentire il parsing JSON

		public string id { get; set; }		// Da query arriva una stringa
		public string nome { get; set; }
	}

}

The response is the following (copy and pasted from the debugger:

" {\"list\":[{\"id\":\"2020\",\"nome\":\"Prova torneo - Trofeo\"},{\"id\":\"2023\",\"nome\":\"36\\u00b0 Torneo - Trofeo Ermes Fontana\"}],\"ret\":\"ok\"}"

The response is without any exception, I set the client members as

			ThrowOnDeserializationError = true,
			FailOnDeserializationError = true,

and Data is null without errors.

If I visualize the Content member with the JSON viewer I correctly see:

Just one note: the contentType is text/html --> is it misunderstood ??

Thanks!

I recovered my last version of the project: it had restsharp 110.2.0 and it was Ok.
Hope it help .

What's the code for TorneiQuery?

Also, text/html is apparently wrong as the response is JSON and it should have an appropriate content type, but it should work regardless.

[alexeyzimarev]

This would work:

var response = client.ExecuteGet<Torneo[]>(request);

[SteMMo33]

Sorry I missed the class(es):

		public class TorneoQuery
		{
			public string id { get; set; }
			public string nome { get; set; }
		}

		class TorneiQuery
		{
			public string ret { get; set; }
			public List<TorneoQuery> list { get; set; }
		}

I returned to 110.2.0 and I have no problems.

When you say this

Some JSON replies that until yesterday was parsed, now they are not. (???)

what does it mean?

[SteMMo33]

Sorry .. simply that in that day I forgot that I had a library update to 111.1.0.
Then I restored restsharp version 110.2.0 and since that day the parses were Ok.

[alexeyzimarev]

That I understand, but I still don't know what you've got with 111.0

[SteMMo33]

Version 111.1.0 does not parse the json string that 110.2.0 does.

[alexeyzimarev]

Sorry, I don't know how to help you. If you can create a reproduction repo, it can be fixed. Otherwise, it's too hard as you have some JSON and some classes on your side, which I can't see. RestSharp has a bunch of tests for JSON calls and all of them pass on the latest version, so I am not sure what is wrong there.

Today I updated the verion to the lastone at this moment: 111.3.0.
Again the parse is failed but the StatusCode=OK and no any Exceptions.
The Content is:

 {"list":[{"id":"2020","nome":"Prova torneo - Trofeo"},{"id":"2023","nome":"36\u00b0 Torneo - Trofeo Ermes Fontana"}],"ret":"ok","user":"username","pass":"password","digest":null}

The error is that response.Data is null.
The code is:

var response = client.ExecuteGet<TorneiQuery>(request);

and the class(es) is:

	public class TorneoQuery
	{
		public string id { get; set; }
		public string nome { get; set; }
	}

	class TorneiQuery
	{
		public string ret { get; set; }
		public List<TorneoQuery> list { get; set; }
	}

Again, with version 110.2.0 everyting is ok.
Hope this help .. thanks
