有人能帮忙吗?这意味着它对我的项目非常有用。谢谢你. .
IIS7在其配置文件中定义了一个defaultDocument节,该节可以在%WinDir%'System32'InetSrv'Config文件夹中找到。最有可能的是文件索引。aspx已经在IIS7的一个配置文件中被定义为默认文档,并且你要在web.config中再次添加它。
我怀疑删除这一行<add value="index.aspx" />
将解决您的问题。
你的配置的defaultDocument部分看起来像:
<defaultDocument>
<files>
<remove value="default.aspx" />
<remove value="index.html" />
<remove value="iisstart.htm" />
<remove value="index.htm" />
<remove value="Default.asp" />
<remove value="Default.htm" />
</files>
</defaultDocument>
注意索引。在IIS管理器中,aspx仍然会出现在您站点的默认文档列表中。
有关IIS7配置的更多信息,请单击此处
您所需要的只是一个<clear />
标签。下面是一个例子:
<configuration>
<system.webServer>
<defaultDocument>
<files>
<clear />
<add value="default.aspx" />
</files>
</defaultDocument>
</system.webServer>
</configuration>
理想的情况是在配置中有<add value="default.aspx" />
,这样应用程序就可以部署到任何服务器上,而不必重新配置。恕我直言,我认为IIS的实现很差。
我们使用了以下内容使我们的默认文档设置更健壮,并通过使用规范的URL使其对SEO更友好:
<configuration>
<system.webServer>
<defaultDocument>
<files>
<remove value="default.aspx" />
<add value="default.aspx" />
</files>
</defaultDocument>
</system.webServer>
</configuration>
Remove元素会清除这些错误。这背后的原因是继承的设置。您的应用程序将从其父程序的配置文件和机器(服务器)的配置文件中继承一些设置。
您可以在添加它们之前使用remove标签删除这些重复的标签,或者在上层配置文件中使这些标签不可继承。
请记住以下几点:
在IIS中,如果你有一个名为Pages的文件夹,其中包含多个网站。网站将从web继承设置。配置文件从父目录。因此,即使文件夹页面(在这个例子中是Pages)不是一个网站,但包含一个网页。配置文件,其中列出的所有网站将继承设置。
我得到了同样的错误,当我不知不觉地删除了DefaultAppPool本身的所有默认页面。
我已经点击了DefaultAppPool并打开了默认文档。然后单击Actions窗格上的Revert to Parent链接。默认文档又出现了,因此解决了问题。我不确定这是最好的方法,但这是我刚刚遇到的错误,希望与您分享。
对于我来说,在windows server 2012 R2中,我通过从web中删除重复来解决这个问题。我发现这行重复了两次,我删除了一行并保留了另一行
