A Native Collection has not been disposed, resulting in a memory leak.  Enable Full StackTraces to get more details.

原因：

数据请求提交过程中，UnityWebRequest 不时出现数据没有释放的情况，偶尔会一部分数据
内存溢出情况：

解决方法：

UnityWebRequest 前加上using

 IEnumerator Post(callBack call)
    {
        WWWForm form = new WWWForm();
        form.AddField("name", "myData");
        form.AddField("id", "myData");
        form.AddField("message", "myData");

        using UnityWebRequest www = UnityWebRequest.Post(HttpConfig.goServer_url+postUrl, form);
        yield return www.SendWebRequest();

        if (www.result != UnityWebRequest.Result.Success)
        {
            Debug.Log(www.error);
        }
        else
        {
            Debug.Log("Form upload complete!");
            Debug.Log(www.downloadHandler.text);
        }
    }
