unity UnityWebRequest 的request.downloadHandler 空应用

private IEnumerator Test_Get()
{UnityWebRequest request = new UnityWebRequest(tmp_getURL, "GET");yield return request.SendWebRequest();if (request.result == UnityWebRequest.Result.ConnectionError || request.result == UnityWebRequest.Result.ProtocolError){Debug.LogError($"Post Error: {request.error}");}else{Debug.Log($"Post Success: {request.downloadHandler.text}");}
}

解决办法

创建一个 DownloadHandlerBuffer 对象。

private IEnumerator Test_Get()
{UnityWebRequest request = UnityWebRequest.Get(tmp_getURL);request.downloadHandler = new DownloadHandlerBuffer(); // 确保有下载处理器yield return request.SendWebRequest();if (request.result == UnityWebRequest.Result.ConnectionError || request.result == UnityWebRequest.Result.ProtocolError){Debug.LogError($"Get Error: {request.error}");}else{Debug.Log($"Get Success: {request.downloadHandler.text}");}
}
