UnityWebRequest.Dispose

설명

Signals that this UnityWebRequest is no longer being used, and should clean up any resources it is using.

You must call Dispose once you have finished using a UnityWebRequest object, regardless of whether the request succeeded or failed.

For safety, it is usually a best practice to employ the using statement to ensure that a [UnityWebRequest] is properly cleaned up in case of uncaught exceptions.

            yield return request.Send();
            Debug.Log("Server responded: " + request.downloadHandler.text);
