C# 无法使用IIS express在浏览器中打开asp.net mvc网站

我无法打开url为“”的asp.net mvc网站（c#）https://localhost:44366在浏览器中，当模式为“IIS Express”时。但是当我使用“WebApplication5”模式时，我可以打开https://localhost:5001.

launchSettings.json

{
“iisSettings”：{
“Windows身份验证”：false，
“匿名身份验证”：正确，
“iisExpress”：{
“应用程序URL”：http://localhost:44179",
“sslPort”：44366
}
},
“概况”：{
“IIS Express”：{
“命令名”：“IISExpress”，
“启动浏览器”：正确，
“环境变量”：{
“ASPNETCORE_环境”：“开发”，
“ASPNETCORE_HostingStartupAssemblys”：“Microsoft.ASPNETCORE.Mvc.Razor.RuntimeCompilation”
}
},
“WebApplication5”：{
“命令名”：“项目”，
“dotnetRunMessages”：“true”，
“启动浏览器”：正确，
“应用程序URL”：https://localhost:5001;http://localhost:5000",
“环境变量”：{
“ASPNETCORE_环境”：“开发”，
“ASPNETCORE_HostingStartupAssemblys”：“Microsoft.ASPNETCORE.Mvc.Razor.RuntimeCompilation”
}
}
}
}

调试时的Visual Studio 2019输出：

Starting IIS Express ...
Successfully registered URL "http://localhost:44179/" for site "WebApplication5" application "/"
Successfully registered URL "https://localhost:44366/" for site "WebApplication5" application "/"
Registration completed for site "WebApplication5"
IIS Express is running.

在appsettings.json文件中设置

“sslPort”：0

。它将作为HTTP工作。

添加

“applicationUrl”：https://localhost:5001;http://localhost:5000“，

在

IIS EXPRESS中

section@viveknuna我试过了，但没用。你试过了吗？

“launchUrl”：“default”

。其中

default

是您的默认控制器name@viveknuna我创建了一个新项目，并取消选中了“配置HTTPS”选项。它现在可以工作了。无论如何，谢谢。：）另一种方法是你可以设置

“sslPort”：0

，它会工作的。不需要创建新项目
