Sitecore 体验分析图表问题

Question

将我的网站从 7.1 升级到 8.1 后，在体验分析中打开任何页面时出现以下错误消息：

"The 'Graph Name' graph cannot be displayed due to a server error. Contact you system administrator."

以下调用在浏览器控制台上显示 500 错误：

"http://sitename/sitecore/api/ao/aggregates/all/DC0DB760B0F54690B9EB1BBF7A4F7BD1/all?&dateGrouping=collapsed&&keyTop=8&keyOrderBy=valuePerVisit-Desc&dateFrom=07-04-2016&dateTo=05-07-2016&keyGrouping=by-key"

我检查了日志文件，那里没有记录服务器错误！

更多信息：

错误信息： "ValueFactory attempted to access the Value property of this instance."

还有

有什么想法吗？

Answer 1

此错误的原因是您可能在代码中使用了 Web Api。要将网站 api 与站点核心集成，您需要按如下方式扩展 global.asax

 public class GlobalExtended : Sitecore.Web.Application
{
   protected void Application_Start(object sender, EventArgs e)
   {
    GlobalConfiguration.Configure(ConfigureRoutes);
    }

  public static void ConfigureRoutes(HttpConfiguration config)
  {
   config.Routes.MapHttpRoute("DefaultApiRoute",
    "api/{controller}/{action}/{id}",
     new { id = RouteParameter.Optional });

    GlobalConfiguration.Configuration.MapHttpAttributeRoutes();
    GlobalConfiguration.Configuration.Formatters.Clear();
    GlobalConfiguration.Configuration.Formatters.Add(new JsonMediaTypeFormatter());
   }
}

Answer 2

Sitecore 支持为此提供了原因和解决方案，并认为会添加它以防其他人发生同样的问题：

原因：

看起来问题是由 Web API 配置中的冲突引起的

据我所知，在应用程序启动期间执行了以下代码：

void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
    System.Web.Http.GlobalConfiguration.Configure(MyDll.WebApiConfig.Register);
}

解法：

作为替代方法，可以在应用程序启动时将此代码移动到 "initialize" 管道到运行。

如果自定义代码在默认 Sitecore.ExperienceAnalytics.Api.Pipelines.Initialize.WebApiInitializer 处理器之后运行，则将首先加载体验分析配置。

例如： 1) 创建 "initialize" 流水线处理器

internal class WebApiInitializer
{
    public void Process(PipelineArgs args)
    {
        System.Web.Http.GlobalConfiguration.Configure(Register);
    }
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();
    }
}

2) 创建配置文件并放入 Include/Z.MapRoutes fodler（因此它将最后加载）：

<configuration xmlns:x="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <pipelines>
      <initialize>
        <processor type="HttpAttributeRouting.WebApiInitializer, HttpAttributeRouting" x:after="processor[position()=last()]" />
      </initialize>
    </pipelines>
  </sitecore>
</configuration>
