macos - 协同设计/打包后 OSX Mac 商店应用程序联网失败

Question

我有一个内置在 Unity 中的应用程序，并设置要在 Mac App Store 上发布，它的网络任务在 OS X 构建中工作得很好，这不适用于应用程序商店，但一旦构建需要 App Store 验证/协同设计联网失败。该应用程序和构建过程不久前还有效，但现在失败了。

我在权利中包含了网络权限，并且在系统控制台中没有看到任何沙盒错误的痕迹。应用内购买网络调用成功，但如果我检查终端中其他任何内容的流量，则没有数据移入或移出。

因此，我想知道是否有人对可能导致此问题的原因有任何想法，或者我可以使用进一步的测试来找出问题所在。

我从来没有弄清楚 Unity 的 WWW 类出了什么问题，但我能够使用 System.Net.WebClient 类解决这个问题。我实现了一个简单的包装器，它具有与 Unity 的 WWW 类类似的接口(interface)。这是我使用的代码:

using System;
using System.Net;
using System.Net.Security;
using System.Text;

/// <summary>
/// Web request using the WebClient class.
/// </summary>
/// <seealso cref="Assets.Scripts.WebRequest" />
internal class WebRequest
{
   /// <summary>
   /// The web client.
   /// </summary>
   private WebClient _client;

   /// <summary>
   /// The error message.
   /// </summary>
   private string _error;

   /// <summary>
   /// The is done flag.
   /// </summary>
   private bool _isDone;

   /// <summary>
   /// The progress.
   /// </summary>
   private float _progress;

   /// <summary>
   /// The text.
   /// </summary>
   private string _text;

   /// <summary>
   /// Initializes a new instance of the <see cref="WebRequest"/> class.
   /// </summary>
   /// <param name="url">The URL.</param>
   public WebRequest(string url)
   {
      this._client = new System.Net.WebClient();
      this._client.DownloadProgressChanged += this.WebClientProgressChanged;
      this._client.DownloadStringCompleted += this.WebClientDownloadCompleted;
      this._client.DownloadStringAsync(new Uri(url));
   }

   /// <summary>
   /// Initializes a new instance of the <see cref="WebRequestDotNet"/> class.
   /// </summary>
   /// <param name="url">The URL.</param>
   /// <param name="form">The form.</param>
   public WebRequest(string url, UnityEngine.WWWForm form)
   {
      this._client = new System.Net.WebClient();
      this._client.UploadProgressChanged += this.WebClientUploadProgressChanged;
      this._client.UploadDataCompleted += this.WebClientUploadCompleted;

      this._client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";

      // Try to get the header from the Unity form
      foreach (var header in form.headers)
      {
         const string ContentType = "Content-Type";
         if (header.Key == ContentType)
         {
            string contentType = header.Value;
            this._client.Headers.Remove(ContentType);
            this._client.Headers[ContentType] = contentType;
         }
      }

      this._client.UploadDataAsync(new Uri(url), form.data);
   }
