ASP.. NET MVC:它只用于开发，而不用于生产

Question

我在生产环境中部署mschart时遇到了问题。

该应用程序是一个。net 4 ASP。. NET MVC 2站点，使用IIS 7.5.

当我在Visual Studio的开发服务器上运行时，一切都很好，但是当我试图在现场站点上运行带有图表的页面时，我得到以下错误:

Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerWrapper'.
STACK TRACE:

在网上看了一堆，我一直在努力找到一个明确的答案，如何让MVC mschart在。net 4中工作，所以我已经拿起零零碎碎的每一个地方，把我的web.config。我不确定它们是否都是必需的，或者是否在正确的地方。应用程序的根web。配置看起来是这样的(在删除多余的东西之后):

<?xml version="1.0"?>
<configuration>
    <appSettings>
        <add key="ChartImageHandler" value="storage=file;URL=~/App_Data/MicrosoftChartControls/;timeout=20;" />
    </appSettings>
    <system.web>
        <compilation debug="true" targetFramework="4.0">
            <assemblies>
                <add assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            </assemblies>
        </compilation>
        <httpHandlers>
            <add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
        </httpHandlers>
    <system.web>
</configuration>

还有我的网。

<?xml version="1.0"?>
<configuration>
    <system.web>
        <pages>
            <controls>
                <add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
            </controls>
        </pages>
    </system.web>
    <system.webServer>
        <handlers>
            <remove name="ChartImageHandler"/>
            <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
        </handlers>
    </system.webServer>
</configuration>

在我的Global.asax.cs中，我这样做了:

protected void Application_Start()
{
    RouteTable.Routes.Ignore("{*pathInfo}", new { pathInfo = @"^.*(ChartImg.axd)$" });
    // ...
}

我的部分视图是这样呈现这个图表的，Model.Graph是Chart控件:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<dynamic>" %>
<%@ Register Assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
    Namespace="System.Web.UI.DataVisualization.Charting" TagPrefix="asp" %>
<h3><%: Model.ReportName %></h3>
<% chartPanel.Controls.Add(Model.Graph); %>
<asp:Panel ID="chartPanel" runat="server"></asp:Panel>

被渲染的视图是在一个区域中，如果有效果的话

Answer 1

您是否在IIS中检查了您是否为aspx页面配置了所需的映射?

进入IIS管理器->默认网站->处理程序映射

Answer 2

啊，找到问题了。下面的<handlers>部分我已经放在网上了。

<system.webServer>
    <handlers>
        <remove name="ChartImageHandler"/>
        <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    </handlers>
</system.webServer>

将此移动到web。
