c# - 更改 launchSettings.json 中的端口会导致到达 "This site can’”

Question

我使用 VS2017 创建了一个空的 asp.net 核心应用程序。我唯一改变的是"sslPort": launchSettings.json 文件中的属性。
当我点击运行 IIS Express chrome 时，网址为 https://localhost:9995/并给出 This site can't be reached The connection was reset.错误

我的launchSettings.json如下

{
  "iisSettings": {
    "windowsAuthentication": false, 
    "anonymousAuthentication": true, 
    "iisExpress": {
      "applicationUrl": "http://localhost:39566",
      "sslPort": 9995
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "JccWeb2": {
      "commandName": "Project",
      "launchBrowser": true,
      "applicationUrl": "https://localhost:5001;http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

我究竟做错了什么？

如 docs 中所述，您在 IIS Express 中使用了不兼容的 ssl 端口。
而不是 "sslPort": 9995 , 替换为 44300 到 44399 之间的端口号。

If you want to test SSL access to your site, you can do this with IIS Express by using an SSL port between 44300 and 44399 and using the IIS Express self-signed certificate. Trying to use SSL with a port outside this range results in a URL binding failure when your website is launched under IIS Express.
