Question

我有一个内置于Unity的应用程序，并且设置将在Mac App Store上发布，该应用程序的网络任务在OS X构建中运行良好，不适用于应用程序商店，但一旦构建需要App Store验证/代码签名使网络失败。应用程序和构建过程不久前工作，但现在失败了。

我在权利中包含网络权限，我在系统控制台中没有看到任何沙箱错误的痕迹。应用内购买网络呼叫正在成功，但如果我检查终端中的任何其他内容的流量，则没有数据移入或移出。

所以我想知道是否有人对可能导致此问题或进一步测试的问题有任何想法，我可以用它来弄清楚问题可能是什么。

我从未弄清楚Unity的WWW类有什么问题，但是我能够使用System.Net.WebClient类来解决这个问题。我实现了一个简单的包装器，它与Unity的WWW类具有类似的接口。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);
   }

   /// <summary>
   /// Gets the error message. Returns null if there is no error.
   /// </summary>
   /// <value>
   /// The error message.
   /// </value>
   public string Error
   {
      get
      {
         return this._error;
      }
   }

   /// <summary>
   /// Gets a value indicating whether this request is done.
   /// </summary>
   /// <value>
   ///   <c>true</c> if this instance is done; otherwise, <c>false</c>.
   /// </value>
   public bool IsDone
   {
      get
      {
         return this._isDone;
      }
   }

   /// <summary>
   /// Gets the progress, 0 to 1.
   /// </summary>
   /// <value>
   /// The progress.
   /// </value>
   public float Progress
   {
      get
      {
         return this._progress / 100.0f;
      }
   }

   /// <summary>
   /// Gets the resulting text.
   /// </summary>
   /// <value>
   /// The text.
   /// </value>
   public string Text
   {
      get
      {
         return this._text;
      }
   }

   /// <summary>
   /// Called when the download is complete.
   /// </summary>
   /// <param name="sender">The sender.</param>
   /// <param name="e">The <see cref="DownloadStringCompletedEventArgs"/> instance containing the event data.</param>
   private void WebClientDownloadCompleted(object sender, DownloadStringCompletedEventArgs e)
   {
      if (e.Error != null)
      {
         this._error = e.Error.ToString();
      }
      else
      {
         this._text = e.Result;
      }

      this._isDone = true;
   }

   private void WebClientProgressChanged(object sender, DownloadProgressChangedEventArgs e)

      this._progress += e.ProgressPercentage;
   }

      {
         this._error = e.Error.ToString();
      }
      else
      {
         this._text = Encoding.UTF8.GetString(e.Result);
      }

      this._isDone = true;
   }

   /// <summary>

   private void WebClientUploadProgressChanged(object sender, UploadProgressChangedEventArgs e)
   {
      this._progress += e.ProgressPercentage;
   }
}
