Asp.net @内容在一台服务器上不解析绝对路径，但在另一台服务器上解析绝对路径

我们目前在同一个域上有两个不同的服务器。但只有一台服务器解决了这个问题

@Url.Content（“~/api/User”）'

作为

其中，其他服务器无法绝对解决该问题；相反，它相对像

api/用户

代码库是相同的，我们使用的是MVC4。我不确定我们哪里出了问题，或者是否需要进行任何IIS/DNS设置才能修复此问题

感谢所有的帮助；谢谢：）

这与IIS web服务器中返回路径到

http://domain.com/virtualdirectory/api/User

请看下面@Url.Content的源代码部分：

private static string GenerateClientUrlInternal(HttpContextBase httpContext, string contentPath)
{
     if (String.IsNullOrEmpty(contentPath))
     {
          return contentPath;
     }

     // can't call VirtualPathUtility.IsAppRelative since it throws on some inputs
     bool isAppRelative = contentPath[0] == '~';
     if (isAppRelative)
     {
           string absoluteContentPath = VirtualPathUtility.ToAbsolute(contentPath, httpContext.Request.ApplicationPath);
           return GenerateClientUrlInternal(httpContext, absoluteContentPath);
     }

     // we only want to manipulate the path if URL rewriting is active for this request, else we risk breaking the generated URL
     bool wasRequestRewritten = _urlRewriterHelper.WasRequestRewritten(httpContext);
     if (!wasRequestRewritten)
     {
            return contentPath;
     }

     // Since the rawUrl represents what the user sees in his browser, it is what we want to use as the base
     // of our absolute paths. For example, consider mysite.example.com/foo, which is internally
     // rewritten to content.example.com/mysite/foo. When we want to generate a link to ~/bar, we want to
     // base it from / instead of /foo, otherwise the user ends up seeing mysite.example.com/foo/bar,
     // which is incorrect.
     string relativeUrlToDestination = MakeRelative(httpContext.Request.Path, contentPath);
     string absoluteUrlToDestination = MakeAbsolute(httpContext.Request.RawUrl, relativeUrlToDestination);
     return absoluteUrlToDestination;
}

使用以下代码检查您的web服务器是否正在重写URL：

bool requestWasRewritten = (httpWorkerRequest != null && httpWorkerRequest.GetServerVariable("IIS_WasUrlRewritten") != null);

而且：

private volatile bool _urlRewriterIsTurnedOnCalculated = false;
        private bool _urlRewriterIsTurnedOnValue;
        private object _lockObject = new object();
        private bool IsUrlRewriterTurnedOn(HttpContextBase httpContext)
        {
            // Need to do double-check locking because a single instance of this class is shared in the entire app domain (see PathHelpers)
            if (!_urlRewriterIsTurnedOnCalculated)
            {
                lock (_lockObject)
                {
                    if (!_urlRewriterIsTurnedOnCalculated)
                    {
                        HttpWorkerRequest httpWorkerRequest = (HttpWorkerRequest)httpContext.GetService(typeof(HttpWorkerRequest));
                        //bool urlRewriterIsEnabled = (httpWorkerRequest != null && httpWorkerRequest.GetServerVariable(UrlRewriterEnabledServerVar) != null);
                        bool urlRewriterIsEnabled = (httpWorkerRequest != null && httpWorkerRequest.GetServerVariable("IIS_UrlRewriteModule") != null);

                        _urlRewriterIsTurnedOnValue = urlRewriterIsEnabled;
                        _urlRewriterIsTurnedOnCalculated = true;
                    }
                }
            }
            return _urlRewriterIsTurnedOnValue;
        }

总之，如果请求和IsUrlRewriterTurnedOn都被重写 返回true，这意味着您的某个web服务器具有IIS重写模块 打开并运行，而另一个没有

希望有帮助

尽管文档说这会生成一个绝对路径，但它就像内部实现返回一个在客户端工作正常的url一样（它调用

PathHelpers.GenerateClientUrl

）。您的第二个应用程序是安装在服务器的根目录中还是虚拟目录中？两者都作为应用程序安装，它们的应用程序池和权限都相同
