我可以使用文件 web.config 以某种方式获取有关错误的其他信息吗?

解决方案

web.config

<httpErrors errorMode="详细信息";/><aspNetCore processPath="dotnet"><环境变量><environmentVariable name="ASPNETCORE_DETAILEDERRORS";值=真"/></环境变量></aspNetCore></system.webServer>

<configuration>
    <system.web>
        <customErrors mode="Off" />
    </system.web>
    <system.webServer>
        <httpErrors errorMode="Detailed" />
    </system.webServer>

Can I somehow get additional information about errors using file web.config?

解决方案

web.config

<system.webServer>
    <httpErrors errorMode="Detailed" />
    <aspNetCore processPath="dotnet">
        <environmentVariables>
            <environmentVariable name="ASPNETCORE_DETAILEDERRORS" value="true" />
        </environmentVariables>
    </aspNetCore>
</system.webServer>
