部署项目到IIS，运行时报错误： An error occurred while starting the application
打开web.config找到stdoutLogEnabled="false"，把该值改为true，即->stdoutLogEnabled="true"
<?xml version="1.0" encoding="utf-8"?> <configuration> <location path="." inheritInChildApplications="false"> <system.webServer> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> </handlers> <aspNetCore processPath="dotnet" arguments=".\CMS.WebApi.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" /> </system.webServer> </location> </configuration>
可看到对应的报错信息。
