在Blazor中使用.NET 5.0 WebAssembly服务器的解决方案是通过创建一个包含服务器端代码的Blazor WebAssembly应用程序。以下是一个基本的示例:
dotnet new blazorwasm --name MyBlazorApp
cd MyBlazorApp
dotnet new web --name MyServerApp
cd MyServerApp
dotnet add reference ../MyServerApp/MyServerApp.csproj
Program.cs
文件中添加服务器端提供程序:using MyServerApp;
var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add("#app");
// 注册服务器端提供程序
builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
builder.Services.AddScoped(); // 添加服务器端提供程序
await builder.Build().RunAsync();
ServerAppService.cs
:using System.Net.Http;
using System.Threading.Tasks;
namespace MyServerApp
{
public class ServerAppService
{
private readonly HttpClient _httpClient;
public ServerAppService(HttpClient httpClient)
{
_httpClient = httpClient;
}
public async Task GetServerData()
{
return await _httpClient.GetStringAsync("api/mydata"); // 这里假设服务器端有一个名为mydata的API
}
}
}
MyDataController.cs
:using Microsoft.AspNetCore.Mvc;
namespace MyServerApp.Controllers
{
[ApiController]
[Route("api/[controller]")]
public class MyDataController : ControllerBase
{
[HttpGet]
public ActionResult Get()
{
return "Hello from server!";
}
}
}
Startup.cs
文件中配置API路由:using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
namespace MyServerApp
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
}
cd ..
dotnet run --project MyBlazorApp
现在,你可以在Blazor WebAssembly应用程序中使用ServerAppService
来调用服务器端的API,并获取服务器数据。
请注意,这只是一个基本的示例,你可以根据实际需求进行更多的定制和扩展。
