Hi All,

We have a REST service for logging a user in and this is working with no problems. But if the login is rejected, I'm not sure how to read the json format that the error is in.

It looks like this:

{ "error":
 {"code":"Exception","message":"Invalid user name or password."}
}

I just want the message part. Can anyone tell me how to use a TReader to get that?

Thanks,
Paul

There is a JSON parsing unit in the Component forum.  That can be used as an alternative to the TReader,

Define a class with a published error property which is an object with the two string properties of "code" and "message".
I think it will then be automatic.

Also see the example that comes with EWB - Persistence.

Searching forum you will see Matthew's JSONList.zip where he users TReader and TWriter.
