c# - 抛出异常：根据验证程序，远程证书无效

问题描述

再会，

我在我的一台 PC（Windows 10）上的 Visual Studio 2019 上运行 ASP.NET CORE Blazor 应用程序，它运行良好。我在 VS Code 中在另一台 PC（Windows 7）上打开了相同的项目，并引发了以下异常。

{System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.\r\n ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.\r\n   at System.Net.Security.SslStream.StartSendAuthResetSignal(ProtocolToken message, AsyncProtocolRequest asyncRequest, ExceptionDispatchInfo exception)\r\n   at System.Net.Security.SslStream.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.ProcessReceivedBlob(Byte[] buffer, Int32 count, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.StartReadFrame(Byte[] buffer, Int32 readBytes, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.ProcessReceivedBlob(Byte[] buffer, Int32 count, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.StartReadFrame(Byte[] buffer, Int32 readBytes, AsyncProtocolRequest asyncRequest)\r\n   at System.Net.Security.SslStream.PartialFrameCallback(AsyncProtocolRequest asyncRequest)\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Net.Security.SslStream.ThrowIfExceptional()\r\n   at System.Net.Security.SslStream.InternalEndProcessAuthentication(LazyAsyncResult lazyResult)\r\n   at System.Net.Security.SslStream.EndProcessAuthentication(IAsyncResult result)\r\n   at System.Net.Security.SslStream.EndAuthenticateAsClient(IAsyncResult asyncResult)\r\n   at System.Net.Security.SslStream.<>c.<AuthenticateAsClientAsync>b__65_1(IAsyncResult iar)\r\n   at System.Threading.Tasks.TaskFactory`1.FromAsyncCoreLogic(IAsyncResult iar, Func`2 endFunction, Action`1 endAction, Task`1 promise, Boolean requiresSynchronization)\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Net.Http.ConnectHelper.EstablishSslConnectionAsyncCore(Stream stream, SslClientAuthenticationOptions sslOptions, CancellationToken cancellationToken)\r\n   --- End of inner exception stack trace ---\r\n   at System.Net.Http.ConnectHelper.EstablishSslConnectionAsyncCore(Stream stream, SslClientAuthenticationOptions sslOptions, CancellationToken cancellationToken)\r\n   at System.Net.Http.HttpConnectionPool.ConnectAsync(HttpRequestMessage request, Boolean allowHttp2, CancellationToken cancellationToken)\r\n   at System.Net.Http.HttpConnectionPool.CreateHttp11ConnectionAsync(HttpRequestMessage request, CancellationToken cancellationToken)\r\n   at System.Net.Http.HttpConnectionPool.GetHttpConnectionAsync(HttpRequestMessage request, CancellationToken cancellationToken)\r\n   at System.Net.Http.HttpConnectionPool.SendWithRetryAsync(HttpRequestMessage request, Boolean doRequestAuth, CancellationToken cancellationToken)\r\n   at System.Net.Http.RedirectHandler.SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)\r\n   at System.Net.Http.DiagnosticsHandler.SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)\r\n   at System.Net.Http.HttpClient.FinishSendAsyncUnbuffered(Task`1 sendTask, HttpRequestMessage request, CancellationTokenSource cts, Boolean disposeCts)\r\n   at System.Net.Http.HttpClient.GetStringAsyncCore(Task`1 getTask)\r\n   at Microsoft.AspNetCore.Components.HttpClientJsonExtensions.GetJsonAsync[T](HttpClient httpClient, String requestUri)\r\n   at Workspace2.Pages.OrdersGrid.OnInitializedAsync() in c:\Users\dell\Desktop\Workspace2\Pages\OrdersGrid.razor:line 49}

内部异常为空，错误消息为：The remote certificate is invalid according to the validation procedure.

我正在使用 .NET CORE SDK 3.1.0 预览版 2。这是引发异常的代码：

@code{
    public List<ProjectVM> projectsDataSource { set; get; }

    public void ActionComplete(ActionEventArgs<Order> Args) { }

    protected override async Task OnInitializedAsync()
    {
        try
        {
            projectsDataSource = new List<ProjectVM>();
            projectsDataSource = await Http.GetJsonAsync<List<ProjectVM>>("/Api/Default/GetProjectsList");

        }
        catch(Exception e)
        {

        }
    }
}

请帮忙。

提前致谢。

解决方案

当您使用 VS 2019 运行代码时，它会在您的计算机上安装一个自签名证书以进行 https 重定向。（显示一个消息框，通知证书安装）。

但是 VS 代码不适合你。

阅读此文档应该会有所帮助： https://docs.microsoft.com/en-us/aspnet/core/security/enforcing-ssl?view=aspnetcore-3.0&tabs=visual-studio#trust-the-aspnet-core- https -windows 和 macos 上的开发证书

您可以尝试运行此命令

dotnet dev-certs https --clean
dotnet dev-certs https --trust
