Asp.net core 如何在从服务器端Blazor调用gRPC服务时强制使用HTTP（而不是HTTPS）

好吧，长话短说：

Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Error starting gRPC call. HttpRequestException: An error occurred while sending the request. IOException: The response ended prematurely.", DebugException="System.Net.Http.HttpRequestException: An error occurred while sending the request.
 ---> System.IO.IOException: The response ended prematurely.

• 我有Blazor服务器端应用程序
• 我有gRPC服务
• 两者都在本地主机上运行

问题：

Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Error starting gRPC call. HttpRequestException: An error occurred while sending the request. IOException: The response ended prematurely.", DebugException="System.Net.Http.HttpRequestException: An error occurred while sending the request.
 ---> System.IO.IOException: The response ended prematurely.

• 我无法使其通过HTTP连接（尽管HTTPS可以工作，使用自签名证书）

我所尝试的：

Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Error starting gRPC call. HttpRequestException: An error occurred while sending the request. IOException: The response ended prematurely.", DebugException="System.Net.Http.HttpRequestException: An error occurred while sending the request.
 ---> System.IO.IOException: The response ended prematurely.

• 添加

  AppContext.SetSwitch（“System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport”，true）

  到Blazor应用程序

  Program.cs

  （一开始，在调用builder之前）并使用

  服务.AddGrpcClient（）将我的服务客户端添加到DI

• 正在为我的gRPC服务创建客户端库（包装器），并在构造函数中添加相同的内容，然后再创建客户端：

并亲自将其注册到Blazor应用程序的DI

我从Blazor打电话时得到的信息：

Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Error starting gRPC call. HttpRequestException: An error occurred while sending the request. IOException: The response ended prematurely.", DebugException="System.Net.Http.HttpRequestException: An error occurred while sending the request.
 ---> System.IO.IOException: The response ended prematurely.

值得一提：

Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Error starting gRPC call. HttpRequestException: An error occurred while sending the request. IOException: The response ended prematurely.", DebugException="System.Net.Http.HttpRequestException: An error occurred while sending the request.
 ---> System.IO.IOException: The response ended prematurely.

• AppContext.SetSwitch（“System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport”，true）从控制台应用程序工作

这足以在gRPC端禁用HTTPS吗？

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)

        .UseSerilog()
        .UseWindowsService()

        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseKestrel(options =>
            {
                options.Listen(IPAddress.Loopback, 5666, x => x.Protocols = HttpProtocols.Http2);
            });

            webBuilder.UseStartup<Startup>();
        });
    }
}

公共静态IHostBuilder CreateHostBuilder（字符串[]args）=>
Host.CreateDefaultBuilder（args）
.useserlog（）
.UseWindowsService（）
.ConfigureWebHostDefaults（webBuilder=>
{
webBuilder.UseKestrel（选项=>
{
options.Listen（IPAddress.Loopback，5666，x=>x.Protocols=HttpProtocols.Http2）；
});
webBuilder.UseStartup（）；
});
}
}

在启动配置中禁用Https重定向在哪一端？Blazor还是gRPC？gRPC仅在HTTP（端口5000）上侦听。它应该在gRPC侧。我已更新帖子。另外，我已经从启动选项json中删除了https url。当服务启动时-它不在HTTPS上侦听。
