Sitecore Experience Analytics图表问题

Question

将我的站点从7.1升级到8.1后,在expierence分析中删除任何页面时出现以下错误消息:

"由于服务器错误,无法显示'图表名称'图表.请与系统管理员联系."

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:

错误消息:"ValueFactory尝试访问此实例的Value属性."

也

有任何想法吗？

Answer 1

Sitecore 支持提供了此问题的原因和解决方案，并认为会添加它，以防其他人发生同样的问题：

原因：

该问题似乎是由 Web API 配置冲突引起的

据我所知，在应用程序启动期间执行以下代码：

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

解决方案：

作为替代方法，可以将此代码移至“初始化”管道以在应用程序启动时运行。

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 Experience Analytics 配置。

例如： 1）创建“初始化”管道处理器

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

2) 创建一个配置文件并将其放入 Include/Z.MapRoutes fodler 中（这样它将最后加载）：

<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>
