localhost在已有的web api添加razor页面后返回404（ASP.net 6核心）

Question

我正在尝试将 razor 页添加到具有我的 web api 的项目中。 在我的Views文件夹中，我添加了一个Receiving文件夹，然后在其中添加了Index.cshtml 。 当我编译项目时，它会返回 404 错误，我不知道为什么。

程序.cs

var builder = WebApplication.CreateBuilder(args);

// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddControllers(options => options.SuppressImplicitRequiredAttributeForNonNullableReferenceTypes = true);
builder.Services.AddControllersWithViews();

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

builder.Services.AddHttpContextAccessor();

var connectionString = builder.Configuration.GetConnectionString("DefaultConnection");
builder.Services.AddDbContext<OperationsContext>(x => x.UseSqlServer(connectionString));

builder.Services.AddScoped<IContentRepository, ContentRepository>();
builder.Services.AddScoped<IPackageRepository, PackageRepository>();
builder.Services.AddScoped<IShipmentRepository, ShipmentRepository>();
builder.Services.AddScoped<IVendorRepository, VendorRepository>();
builder.Services.AddRazorPages(c => c.RootDirectory = "/Views"); //adds services for Razor Pages to the app.
var app = builder.Build();


if (app.Environment.IsDevelopment())
{
    app.UseDeveloperExceptionPage();

    // Enable middleware to serve generated Swagger as a JSON endpoint.
    app.UseSwagger();
    app.UseSwaggerUI(c =>
    {
        c.SwaggerEndpoint("v1/swagger.json", "MyAPI V1");
    });
}
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/error");
}
app.UseHttpsRedirection();
app.UseStaticFiles();

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

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Shipment}/{action=Index}/{id?}");

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers();
    endpoints.MapRazorPages();
});

app.Run();

索引.csthml

@{
    ViewData["Title"] = "Receiving";
}

<h2>Shipping System</h2>
<p>Hello world</p>

有谁知道为什么它不显示Index.cshtml ？ 先感谢您。

我加了

public IActionResult Index()
{
    return View();
}

顺便说一句，在ShipmentController.cs中

Answer 1

看起来你是 controller 路由需要一个 ID /{id?}但你的 controller 操作没有id参数。

Answer 2

您是否尝试明确浏览/Receiving/Index ？ 根据您的路线配置，它将从Shipment controller 返回 Index 视图。但我认为您没有创建Shipment controller，而是使用Receiving controller。因此，要么修改MapControllerRoute代码以使用Receiving controller。

app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Receiving}/{action=Index}/{id?}");

或创建货件 controller 并查看索引。

Answer 3

检查视图的属性并确保“构建操作”不是“无”。 您可以将其设置为“内容”。
