.net - WCF 中密码不能包含英镑？

Question

我是否发现了 .NET 框架中的错误或者我做错了什么？

这是这个故事。

我昨天尝试在 WCF channel 上设置密码，如下所示:

channelFactory.Credentials.UserName.UserName = credentials.Username;
channelFactory.Credentials.UserName.Password = credentials.Password;

然后在收到此错误时调用 Web 服务方法:

System.ServiceModel.CommunicationException
   Message=An error (The request was aborted: The request was canceled.) occurred while transmitting data over the HTTP channel.

所以我开始查看它，日志显示我什至没有到达服务器。事实证明，引发异常的 .NET 框架方法 (System.Net.BasicClient.EncodingRightGetBytes(String rawString)) 不喜欢英镑符号 (£)。

我从反射器复制了该方法并编写了一个快速单元测试，并且磅是我在键盘上输入的所有字符中唯一不喜欢的字符:

    internal static byte[] EncodingRightGetBytes(string rawString)
    {
            byte[] bytes = Encoding.Default.GetBytes(rawString);
            string strB = Encoding.Default.GetString(bytes);

            if (string.Compare(rawString, strB, StringComparison.Ordinal) != 0)
        {
            throw ExceptionHelper.MethodNotSupportedException;
        }
        return bytes;
}

这是我检查此方法的单元测试:

[Test]
public void test123()
{
       string domain = "localhost";
       string userName = "lukk";

       string charactersToCheck = @"¬`!£$%^&*()_+={}[]:;@'~#<>,.?/|\";

       foreach (var character in charactersToCheck.ToCharArray())
       {
              string internalGetPassword = character.ToString();

              try
              {
                     // begin - this assignement was copied from System.Net.BasicClient.Lookup method
                     byte[] inArray = EncodingRightGetBytes(
                           (!string.IsNullOrEmpty(domain) ? (domain + @"\") : "")
                           + userName
                           + ":"
                           + internalGetPassword);
                     //end
              }
              catch (Exception ex)
              {
                     Console.WriteLine(string.Format("this character is bad: {0}", internalGetPassword));
              }
       }
}

如您所见，EncodingRightGetBytes 比较两个字符串，如果原始字符串 (rawString) 包含英镑，则它们是不同的。

当我替换“Encoding.Default”时，EncodingRightGetBytes 工作正常。与“Encoding.UTF8。”...

谷歌搜索这个方法名称会返回很少的链接，其中之一是: http://support.microsoft.com/kb/943511

我正在使用 VS 2010，其中一个 asp.net 项目设置为使用 .net 3.5。

那么这会是 .NET 框架中的错误还是我做错了什么？

编辑: 当我在运行测试时在“立即”窗口中查询 Encoding.Default 时，我得到以下信息:

?Encoding.Default
    {System.Text.SBCSCodePageEncoding}

我在 asp 中遇到过类似的情况，我设法通过使用以下配置解决了该问题。

<system.web>    
<globalization
 fileEncoding="utf-8"
 requestEncoding="utf-8"      
 responseEncoding="utf-8"
 culture="en-GB"
 uiCulture="en-GB"/>
...

据我所知，当您设置时，全局化标记对于 WCF 的作用是相同的

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

更新:刚刚检查MSDN页面底部注明以下内容:

The ASP.NET configuration language allows you to specify the culture for individual services. The WCF does not support that configuration setting except in ASP.NET compatibility mode. To localize a WCF service that does not use ASP.NET compatibility mode, compile the service type into culture-specific assemblies, and have separate culture-specific endpoints for each culture-specific assembly.
