我可以将gRPC和webapi应用程序组合到C＃中的.NET Core 3.0吗？ [英] Can I combine a gRPC and webapi app into a .NET Core 3.0 in C#?

问题描述

我正在使用点网核心3.0。

我有gRPC应用程序。我可以通过gRPC协议与之通信。

我认为下一步是添加一些宁静的API支持。我修改了启动类以添加控制器，路由等。...当我尝试使用浏览器导航到API时，无论使用哪种协议（http / https）和端口，都会出现错误 ERR_INVALID_HTTP_RESPONSE。 gRPC应该使用5001，而webapi使用8001。

这是我的启动类：

  public class Startup 
 {
 public void ConfigureServices（IServiceCollection services）
 {
 services.AddGrpc（）; 
 services.AddControllers（）; 
} 
 
 public void Configure（IApplicationBuilder app，IWebHostEnvironment env）
 {
 if（env.IsDevelopment（））
 app.UseDeveloperExceptionPage（）; 
 
 app.UseRouting（）; 
 app.UseHttpsRedirection（）; 
 app.UseAuthorization（）; 
 
 app.UseEndpoints（端点=> 
 {
端点.MapGrpcService< BootNodeService>（）; 
端点.MapControllers（）; 
 
}）; 
} 
} 
  

和我的控制器：

  [ApiController] 
 [Route（ [controller]）] 
公共类AdminController：ControllerBase 
 {
 [HttpGet]公共字符串Get（）
 {return hello; } 
} 
  

有什么想法吗？

Thnx

解决方案

我找到了解决方案。我没有提到我在MacOS上运行并使用Kestrel（这似乎是MacOS和Kestrel的组合）。对于这些丢失的信息，我深表歉意。

该解决方案类似于此处。我必须添加对 options.ListenLocalhost 的webapi端口的调用。

这是代码：

 公共类程序
 {
 public static void Main（string [] args）
 {
 IHostBuilder hostBuilder = CreateHostBuilder（args）; 
 IHost主机= hostBuilder.Build（）; 
 host.Run（）; 
} 
 
 //要在macOS上成功运行gRPC，需要进行其他配置。 
 //有关如何在macOS上配置Kestrel和gRPC客户端的说明，请访问https://go.microsoft.com/fwlink/?linkid=2099682 
公共静态IHostBuilder CreateHostBuilder（string [] args） => 
 Host.CreateDefaultBuilder（args）
 .ConfigureWebHostDefaults（webBuilder => 
 {
 webBuilder.ConfigureKestrel（options => 
 {
 options.ListenLocalhost （5001，o => o.Protocols = 
 HttpProtocols.Http2）; 
 
 //添加此行以解决问题
 options.ListenLocalhost（11837，o => ; o.Protocols = 
 HttpProtocols.Http1）; 
}）; 
 webBuilder.UseStartup< Startup>（）; 
}）; 
} 
} 
  

Thnx

I am using dot net core 3.0.

I have gRPC app. I am able to communicate to it through gRPC protocol.

I thought my next step would be add some restful API support. I modified my startup class to add controllers, routing etc..... When I try navigating to the API using a browser, I get an error "ERR_INVALID_HTTP_RESPONSE" no matter which protocol (http/https) and port I use. gRPC should be using 5001 and webapi using 8001.

heres my startup class:

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddGrpc();
        services.AddControllers();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
            app.UseDeveloperExceptionPage();

        app.UseRouting();
        app.UseHttpsRedirection();
        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapGrpcService<BootNodeService>();
            endpoints.MapControllers();

        });
    }
}

And my controller:

[ApiController]
[Route("[controller]")] 
public class AdminController : ControllerBase 
{ 
    [HttpGet] public string Get() 
    { return "hello"; } 
}

Any thoughts?

Thnx

解决方案

I found the solution. I didn't mention I was running on MacOS and using Kestrel (and it appears the combination of MacOS AND Kestrel is the problem). I apologize for that missing information.

The solution is similar to what is here. I had to add a call to options.ListenLocalhost for the webapi port.

here's the code:

public class Program
{
    public static void Main(string[] args)
    {
       IHostBuilder hostBuilder = CreateHostBuilder(args);
       IHost host = hostBuilder.Build();
       host.Run();
    }

    // Additional configuration is required to successfully run gRPC on macOS.
    // For instructions on how to configure Kestrel and gRPC clients on macOS, visit https://go.microsoft.com/fwlink/?linkid=2099682
    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.ConfigureKestrel(options =>
                {
                    options.ListenLocalhost(5001, o => o.Protocols =
                        HttpProtocols.Http2);

                    // ADDED THIS LINE to fix the problem
                    options.ListenLocalhost(11837, o => o.Protocols =
                        HttpProtocols.Http1);
                });
                webBuilder.UseStartup<Startup>();
            });
    }
}

Thnx
