Unity) Web Request(WWW) Code Example

Web Request(WWW) Code Example

 

Unity 에서 Web Request 를 하는 방식의 일반적인 경우 2가지

코루틴, Task를 활용한 방식에 대한 예시코드이다.

 

Coroutine

private void Test1()
    {
        System.UriBuilder defaultUri = new System.UriBuilder(urlPath);
        //defaultUri.Query += 
        StartCoroutine(GetWebRequestText(defaultUri.Uri.ToString(),
            (success, result) =>
            {
                if (success == false)
                {
                    Debug.LogError($"[WWW] :<color=white>Error Url ::{defaultUri.Uri.ToString()}</color>\n <color=red>Result ::{result}</color>");
                    return;
                }

                Debug.Log($"[WWW] :<color=white> Url ::{defaultUri.Uri.ToString()}</color>\n <color=red>Result ::{result}</color>");
            }));
    }

    private IEnumerator GetWebRequestText(string _url, System.Action<bool, string> _result)
    {
        Debug.Log($"[WWW] URL : <color=white>{_url}</color>");
        using (UnityEngine.Networking.UnityWebRequest www = UnityEngine.Networking.UnityWebRequest.Get(_url))
        {
            yield return www.SendWebRequest();

            string resultValue = string.Empty;
            switch (www.result)
            {
                case UnityWebRequest.Result.Success:
                    resultValue = www.downloadHandler.text;
                    break;

                case UnityWebRequest.Result.ConnectionError:
                case UnityWebRequest.Result.DataProcessingError:
                case UnityWebRequest.Result.ProtocolError:
                    resultValue = www.result.ToString();
                    break;
            }

            _result.Invoke((www.result == UnityWebRequest.Result.Success), resultValue);
          
        }
    }

 

Task

private async void Test2()
    {
        System.UriBuilder defaultUri = new System.UriBuilder(urlPath);
        using var www = UnityWebRequest.Get(defaultUri.Uri.ToString());
        var operation = www.SendWebRequest();
        while (!operation.isDone)
            await Task.Yield();

        if (www.result == UnityWebRequest.Result.Success)
            Debug.Log($"[WWW] :<color=white> Url ::{defaultUri.Uri.ToString()}</color>\n <color=red>Result ::{www.downloadHandler.text}</color>");
    }
