.net core iis 查看报错信息

web.config 修改成下面

<aspNetCore processPath="dotnet" arguments=".l.Web.dll" stdoutLogEnabled="false" stdoutLogFile=".logsstdout" hostingModel="inprocess" >
<environmentVariables>
<environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Development" />
</environmentVariables>
</aspNetCore>
