Question

我的网络应用遇到了问题。当我在本地运行它时，一切都很好，我得到一个rss feed。但是当我将我的应用程序部署到远程计算机时。我收到这样的错误：

Nancy.ViewEngines.ViewNotFoundException: Unable to locate view 'UriFormatException'
Currently available view engine extensions: sshtml,html,htm,cshtml,vbhtml
Locations inspected: views/Renderer/UriFormatException-pl,views/Renderer/UriFormatException,Renderer/UriFormatException-pl,Renderer/UriFormatException,views/UriFormatException-pl,views/UriFormatException,UriFormatException-pl,UriFormatException

这是我的代码的一部分，负责生成rss feed ..

Get["GetFeed"] = _ => 
{
    var feed = _feedProvider.GetFeed();
    var sw = new StringWriter();
    using (var xmlWriter = new XmlTextWriter(sw))
    {
        xmlWriter.WriteProcessingInstruction("xml-stylesheet", "type='text/xsl' href='format.xsl'");
        xmlWriter.Formatting = Formatting.Indented;
        new Rss20FeedFormatter(feed).WriteTo(xmlWriter);
    }

    var res = (Response) sw.ToString();
    res.ContentType = "text/xml";
    return res;
}

此外，我还有另一个返回简单json的操作，它们可以在localmachine和remote上运行。我不知道为什么这个返回与json / html / plain文本不同的特殊代码不能在远程机器上运行。

如果这取决于我使用.net 4.5和Nancy 1.4.2

编辑我添加一个log4net来检查日志以获得更复杂的错误描述。

在日志中，我遇到以下错误：

无效的URI：无法确定URI的格式。

使用Uri的代码中只有一部分是_feedProvider.GetFeed（）函数。

public SyndicationFeed Get()
{
    var alternateLink = new Uri(urlFromConfig);
    var items = GetItems();
    return new SyndicationFeed("Title", "", alternateLink, items)
    {
        Copyright = new TextSyndicationContent(""),
        Language = "pl-PL",
        ImageUrl = new Uri(anotherUrlFromConfig)
    };
}

Answer 1

问题是我的app.config中的任何env都有不同的值。所以在本地机器上一切正常。但是在远程计算机上我得到错误，因为

urlFromConfig

anotherUrlFromConfig

设置为没有

的网址

的http：//

前缀，所以当我添加它时，一切都开始正常工作。

尝试在Nancy中返回rss feed时出现异常
