Question

当我尝试使用数据映射器中介时，我总是收到错误。我尝试将json响应映射到xml。

IEnumerator WaitForRequest(string url)
{

    UnityWebRequest www = UnityWebRequest.Get(url);
    www.SetRequestHeader("Cache-Control", "max-age=0, no-cache, no-store");
    www.SetRequestHeader("Pragma", "no-cache");

    yield return www.Send();
    if (www.isError)
    {
        Debug.Log(www.error);
    }
    else
    {
        Debug.Log("Received " + www.downloadHandler.text);
    }
}

这是我的api。我只是用omdbapi来举个例子。

如果您要映射JSON-＆gt; XML，您需要在Data Mapper Mediator配置中指定。确保将输入类型设置为JSON。

在wso2 esb上发布了beta2版本。因此，请尝试使用针对esb runtime和tooling的beta2包。使用最新的包并尝试。
