图表控件需要 HTTP 处理程序吗？

发布于 2024-10-04 03:11:02 字数 611 浏览 0 评论 0原文

我有一个 VS2010 ASP.NET 4 网站应用程序，我向其中添加了新的图表控件。

当我将其部署到 Web 服务器时，我们收到“内部服务器错误 500”。信息。

我注意到自上次版本以来，以下几行已添加到 web.config 中，与图表控件相关：

  <system.web>
    <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>

如果我从 web.config 中删除此添加的代码，则该站点可以正常工作 - 除了图表功能之外。

如何使网站和图表页面正常工作？

这在 IIS 版本 << 上不是问题。 7.

I have an VS2010 ASP.NET 4 web site app, to which I added the new Chart control.

When I deployed it to our web server, we get a" Internal Server Error 500." message.

I noticed that the following lines were added to the web.config since the last release, related to the chart control:

  <system.web>
    <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>

If I remove this added code from the web.config, the site works--Except for the charting functionality.

How do I get the site and the chart page to work?

This is not an issue on IIS versions < 7.

确保注释掉 system.web 部分中的条目：

<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>

并确保 system.webserver 部分具有以下内容：

<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>

Make sure you comment out the entry in the system.web section:

<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>

And make sure the system.webserver section has the following:

<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>

检查有问题的服务器的事件日志。 Web 服务器 500 错误将是事件日志中的应用程序异常。解决该异常的原因，您就可以开始了。
