无法在 Windows 中的 Visual Studio 代码中启动 kestrel

Question

这是我在运行 dotnet 时遇到的问题

暴击：Microsoft.AspNetCore.Server.Kestrel[0] 无法启动 Kestrel。 System.InvalidOperationException：无法配置 HTTPS 终结点。 未指定服务器证书，并且找不到默认开发者证书或已过期。 要生成开发人员证书，请运行“dotnet dev-certs https”。 要信任证书（仅限 Windows 和 macOS），请运行“dotnet dev-certs https --trust”。

Answer 1

通过创建开发者证书

dotnet dev-certs https

如果您使用的是 mac，请信任证书

dotnet dev-certs https --trust

Answer 2

要手动终止 kestrel 服务器，请使用此命令查看正在运行的进程及其端口 5000 上的 pid

sudo lsof -iTCP -sTCP:LISTEN -P | grep :5000

然后用PID杀死它

sudo kill -9 PID
