我在Windows10PC上开发了VS 2019中的ASP.NET Core2.1Web应用程序。一切正常,在Chrome/IIS中调试没有问题。
我把我的项目复制到了我刚刚开始使用的一台新的Win 10电脑上。
当我尝试在Chrome中用IIS调试这个项目时,我会得到一个错误页面,上面写着:这个站点无法到达.
我遵循了溢出文章中建议的各种修复方法,但似乎没有什么效果。这简直把我逼疯了,浪费了太多时间。我试过所有这些步骤,但没有joy:
launchSettings.json文件
launchSettings.json
{
"iisSettings": {
"windowsAuthentication": true,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "https://localhost:44301/",
"sslPort": 44376
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"CanvasWeb": {
"commandName": "Project",
"launchBrowser": true,
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"applicationUrl": "http://localhost:61900/"
}
}
}
更新
我尝试了以下操作,但仍未解决问题:

此问题可能是IIS Express的HTTPS错误。要检查它:创建一个没有Https的新的ASP.NET核心网络应用程序。取消对/deselect应用程序模板取消检查https的配置中https的配置
如果新的web应用程序运行,则是IIS Express HTTPS问题。使用管理员工具运行流动的power外壳代码将解决IIS问题。

事实上,我遇到了这个问题,并在互联网上做了一些研究,但是,我找不到解决办法。然后,我决定关闭我的防病毒(卡巴斯基互联网安全21.2),并检查它是否能解决问题,之后,一切都开始工作!不幸的是,我找不到负责网络活动的防病毒设置,所以,即使现在,如果我在.NET中测试后端API,我必须关闭防病毒一段时间(
