SSRS Reportviewer无法添加“add”类型的重复集合条目，并将唯一键属性“name”设置为“ReportViewerWebControlHandler”

Question

嘿所有我正在拔出我的头发试图找出为什么这告诉我 ReportViewerWebControlHandler 的密钥有重复。

这是我的 web.config 文件的样子（省略不适用的内容）

<?xml version="1.0" encoding="utf-8"?>
<configuration>

如果我继续并取出＆lt;添加name =“ReportViewerWebControlHandler ... 页面加载，一旦我点击我的报告显示它我得到错误：

报告查看器配置错误

  

报表查看器Web控件HTTP处理程序尚未注册   应用程序的web.config文件。添加到system.web / httpHandlers   web.config文件的一部分，或添加到system.webServer / handlers   Internet Information Services 7或更高版本的部分。

所以现在似乎想要＆lt; add name =“ReportViewerWebControlHandler ... 放回web.config文件???

只是为了踢，我添加了＆lt;添加name =“ReportViewerWebControlHandler ... ”，但取出＆lt; add path =“Reserved.ReportViewerWebControl.axd”...... 并得到相同的错误（500.19）错误。 ...

如果我继续拿出来然后页面加载，一旦我点击我的报告显示它我再次收到错误报告查看器配置错误 ...

我没有看到任何看起来像是重复的东西????任何人都可以指出我的web.config文件???

有什么问题

我遇到了同样的问题。我在处理程序部分下添加了remove部分，它解决了我的问题

<handlers>
<remove name="ReportViewerWebControlHandler" />
<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</handlers>
