404页面可在localhost上运行,但不能在生产环境上运行(Azure Web App) [英] 404 Page works on localhost but not on production (Azure Web App)
问题描述
我在本地主机上有一个404页面,可以正常工作.但是,当将其推送到Azure Web App时,它不会.
我最初是通过发布工具来推送它的,现在我使用从Github中的分支推送的内置功能.</p>
我有以下 web.config :
<system.web>
<customErrors mode="On" defaultRedirect="~/Error/Index">
<error redirect="~/Error/NotFound" statusCode="404" />
<error redirect="~/Error/Index" statusCode="500" />
</customErrors>
<!-- More stuff :-) -->
</system.web>
<system.webServer>
这是我的错误控制器:
public class ErrorController : Controller
{
public ViewResult Index()
{
return View("Error");
}
public ViewResult NotFound()
{
Response.StatusCode = 404;
return View("NotFound");
}
}
我的生产web.config转换文件完全没有更改(请参阅注释中的内容):
<?xml version="1.0"?>
<!-- For more information on using Web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=301874 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<!--
In the example below, the "SetAttributes" transform will change the value of
"connectionString" to use "ReleaseSQLServer" only when the "Match" locator
finds an attribute "name" that has a value of "MyDB".
<connectionStrings>
<add name="MyDB"
connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
-->
<system.web>
<compilation xdt:Transform="RemoveAttributes(debug)" />
<!--
In the example below, the "Replace" transform will replace the entire
<customErrors> section of your Web.config file.
Note that because there is only one customErrors section under the
<system.web> node, there is no need to use the "xdt:Locator" attribute.
<customErrors defaultRedirect="GenericError.htm"
mode="RemoteOnly" xdt:Transform="Replace">
<error statusCode="500" redirect="InternalError.htm"/>
</customErrors>
-->
</system.web>
</configuration>
但是,虽然我的404页面在localhost上可以正常工作,但在生产环境中却得到:
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
而不是漂亮的404页面.
有什么主意吗?
我在本地主机上有一个404页面,可以正常工作.但是,当将其推送到Azure Web App时,不会.
我使用了您的代码并复制了结果.
我在web.config中将<httpErrors existingResponse="PassThrough" />
添加到<system.webServer> </system.webServer>
中,然后它可以正常工作.
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules>
<remove name="ApplicationInsightsWebTracking" />
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler" />
</modules>
<httpErrors existingResponse="PassThrough" />
</system.webServer>
您可以参考以下文章有关更多详细信息.
I have a 404 page on my localhost which works just fine. However, when it's pushed to Azure Web App, it does not.
I pushed it originally through the Publish tool, and right now I use the built in feature that pushes from a branch in Github.
I have the following web.config:
<system.web>
<customErrors mode="On" defaultRedirect="~/Error/Index">
<error redirect="~/Error/NotFound" statusCode="404" />
<error redirect="~/Error/Index" statusCode="500" />
</customErrors>
<!-- More stuff :-) -->
</system.web>
<system.webServer>
This is my error controller:
public class ErrorController : Controller
{
public ViewResult Index()
{
return View("Error");
}
public ViewResult NotFound()
{
Response.StatusCode = 404;
return View("NotFound");
}
}
My production web.config transformation file has not been changed at all (see how stuff is in comments):
<?xml version="1.0"?>
<!-- For more information on using Web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=301874 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

"connectionString" to use "ReleaseSQLServer" only when the "Match" locator
finds an attribute "name" that has a value of "MyDB".
<connectionStrings>
<add name="MyDB"
connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
-->
<system.web>
<compilation xdt:Transform="RemoveAttributes(debug)" />
<!--

<customErrors> section of your Web.config file.

<customErrors defaultRedirect="GenericError.htm"
mode="RemoteOnly" xdt:Transform="Replace">
<error statusCode="500" redirect="InternalError.htm"/>
</customErrors>
-->
</system.web>
</configuration>
However, while my 404 page works just fine in localhost, in production I get:
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
Instead of a nice looking 404 page.
Any idea?
I have a 404 page on my localhost which works just fine. However, when it's pushed to Azure Web App, it does not.
I used your code and reproduced your results.
I add <httpErrors existingResponse="PassThrough" />
to <system.webServer> </system.webServer>
in the web.config ,then it works fine.
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<modules>
<remove name="ApplicationInsightsWebTracking" />
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler" />
</modules>
<httpErrors existingResponse="PassThrough" />
</system.webServer>
