如何更改 ASP.NET Core 6 中的 Grpc 端口？

Question

我正在嘗試更改 ASP.NET Core 6 Grpc 應用程序中的 HTTPS 端口，但只要未設置特定端口（在我的情況下為 7113），應用程序總是顯示錯誤。 我打算對應用程序進行 docker 化，並且需要動態設置 IP。 這是我的 Program.cs 文件，

global using dtms_service_master.Models.Context;
using dtms_service_master.Controllers;
using dtms_service_master.Models;
using dtms_service_master.Repositories;
using dtms_service_master.Services;
using Microsoft.AspNetCore.Server.Kestrel.Core;
using Microsoft.EntityFrameworkCore;
using Microsoft.OpenApi.Models;

var builder = WebApplication.CreateBuilder(args);

builder.WebHost.ConfigureKestrel(serverOptions =>
{
    serverOptions.ListenAnyIP(80, listenOptions =>
    {
        listenOptions.Protocols = HttpProtocols.Http1;
    });
    serverOptions.ListenAnyIP(7113, listenOptions => // in my case this needs always to be 7113 :(
    {
        listenOptions.Protocols = HttpProtocols.Http2;
        listenOptions.UseHttps();
    });
});

var Configuration = builder.Configuration;

// 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

// Add services to the container.
builder.Services.AddGrpc();
builder.Services.AddGrpcHttpApi();
builder.Services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
});
builder.Services.AddGrpcSwagger();

builder.Services.AddGrpcReflection();

builder.Services.AddCors(o =>
    o.AddDefaultPolicy(builder =>
    {
        builder.WithOrigins("*")
               .AllowAnyMethod()
               .AllowAnyHeader()
               .WithExposedHeaders(
                    "Grpc-Status",
                    "Grpc-Message",
                    "Grpc-Encoding",
                    "Grpc-Accept-Encoding");
    }));

builder.Services.AddDbContextFactory<ServiceMasterContext>(
    options => options.UseNpgsql(Configuration.GetConnectionString("DefaultConnection")));
builder.Services.AddRepository();
builder.Services.AddServices();
builder.Services.AddAutoMapper(typeof(Mapper));
builder.Services.Configure<KestrelServerOptions>(options => options.AllowSynchronousIO = true);

var app = builder.Build();

app.UseSwagger();
app.UseSwaggerUI(c =>
{
    c.SwaggerEndpoint("/swagger/v1/swagger.json", "gRPC HTTP API Example V1");
});

app.UseRouting();
app.UseGrpcWeb(new GrpcWebOptions { DefaultEnabled = true });
app.UseCors();

if (app.Environment.IsDevelopment())
    app.MapGrpcReflectionService();

app.UseEndpoints(endpoints =>
{
    endpoints.MapGrpcService<GreeterService>();
    endpoints.MapGrpcService<DummyController>();
    endpoints.MapGrpcService<VendorController>();
});

app.MapGet("/", () => "Communication with gRPC endpoints must be made through a gRPC client. To learn how to create a client, visit: https://go.microsoft.com/fwlink/?linkid=2086909");

app.Run();

這是我之前提到的錯誤，

知道如何正確更改 HTTPS 端口嗎？

Answer 1

由於您使用的是 Docker ，因此您需要使用docker run -p命令公開端口。 檢查它的鏈接here 。
