当'dotnet运行‘时无法启动Kestrel

Question

我最近删除了我电脑上记忆中的一个Wi。突然，所有的项目都失败了。

这是控制台输出

$ dotnet run
info: Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[0]
      User profile is available. Using '/Users/user/.aspnet/DataProtection-Keys' as key repository; keys will not be encrypted at rest.

我在Mac上使用了2019。.NET核心SDK和运行时版本：

dotnet --version
2.2.401

dotnet --list-sdks
2.2.401 [/usr/local/share/dotnet/sdk]

dotnet --list-runtimes
Microsoft.AspNetCore.All 2.2.6 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.2.6 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.2.6 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]

我看了一些堆栈溢出的答案，他们认为这可能是证书问题。我尝试过使用dotnet dev-certs工具来解决问题，但它不起作用。另外，我遇到了一些奇怪的事情：

dotnet dev-certs https --check --verbose
No valid certificate found.

dotnet dev-certs https
A valid HTTPS certificate is already present.

dotnet dev-certs https --trust
Trusting the HTTPS development certificate was requested. If the certificate is not already trusted we will run the following command:
'sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain <<certificate>>'
This command might prompt you for your password to install the certificate on the system keychain.
A valid HTTPS certificate is already present.

dev-certs检查选项生成与创建新搜索的命令相矛盾的结果

dotnet-dev-certs版本是2.2.0

在我的密钥链中，没有本地主机的证书。然后，我尝试重新安装dotNET SDK和Visual，但也不起作用。

Answer 1

我正在经历同样的问题，最后，我在命令提示符下完成了两件事情。

1. dotnet certs https --干净
2. dotnet certs https --信任

C:\Users\saifs>dotnet开发证书https -清洁HTTPS开发证书从机器.可能会显示提示符以确认某些证书的删除。

成功生成了https开发人员证书C:\Users\saifs>dotnet开发证书。

请求C:\Users\saifs>dotnet开发证书- https -信任HTTPS开发证书。如果证书以前不受信任，则将显示确认提示。在提示符上单击“是”以信任证书。有效的HTTPS证书已经存在。
