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}");
    }
}
