如何解决找不到网址的网页服务器未返回index.html
我分别构建了react（前端）和asp.netcore webapi（后端），并将webapi发布到本地文件夹，并复制到远程服务器（plesk面板）上的httpdocs。
然后在dist文件夹的前端复制内容（即index.html和main-bundle.js文件上使用“ npm run build”命令。
现在前端工作或后端工作如下：
如果我使用默认的web.config文件，则网站前端可以运行，但是webApi.dll不起作用，因此api调用获取数据不起作用。
如果我使用以下web.config文件，则后端可以工作，但服务器不会重新调整index.html文件，因此，在新设备或浏览器上加载时显示http 404错误。
web.config如下：

我发现webapi没有index.html服务的原因。如果它已经加载到浏览器中，则该网站可以正常运行。
httpdocs文件夹包含index.html和main-bundle.js文件，服务器无法提供这些文件。
所以我认为我们必须查看用于webapi而不是spa模板的startup.cs文件。
这是startup.cs

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

using System.Collections.Generic;

using System.Threading.Tasks;
using WebApi.Helpers;
using WebApi.Services;
namespace WebApi
{
public class Startup
{
private readonly IWebHostEnvironment _env;
private readonly IConfiguration _configuration;
public Startup(IWebHostEnvironment env,IConfiguration configuration)
{
_env = env;
_configuration = configuration;
}
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// use sql server db in production and sqlite db in development
//if (_env.IsProduction())
services.AddDbContext<DataContext>();
//else
// services.AddDbContext<DataContext,SqliteDataContext>();
services.AddDbContext<CourseDbContext>();
services.AddCors();
// In production,the React files will be served from this directory
services.AddControllers();
// copied mix spa code here
//
services.AddAutoMapper(AppDomain.CurrentDomain.GetAssemblies());
// configure strongly typed settings objects
var appSettingsSection = _configuration.GetSection("AppSettings");
services.Configure<AppSettings>(appSettingsSection);
// configure jwt authentication
var appSettings = appSettingsSection.Get<AppSettings>();
var key = Encoding.ASCII.GetBytes(appSettings.Secret);
services.AddAuthentication(x =>
{
x.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
x.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(x =>
{
x.Events = new JwtBearerEvents
{
OnTokenValidated = context =>
{
var userService = context.HttpContext.RequestServices.GetRequiredService<IUserService>();
var userId = int.Parse(context.Principal.Identity.Name);
var user = userService.GetById(userId);
if (user == null)
{
// return unauthorized if user no longer exists
context.Fail("Unauthorized");
}
return Task.CompletedTask;
}
};
x.RequireHttpsMetadata = false;
x.SaveToken = true;
x.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuerSigningKey = true,IssuerSigningKey = new SymmetricSecurityKey(key),ValidateIssuer = false,ValidateAudience = false
};
});
// configure DI for application services
services.AddScoped<IUserService,UserService>();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app,IWebHostEnvironment env,DataContext dataContext)
{
// migrate any database changes on startup (includes initial db creation)
dataContext.Database.Migrate();
//app.UseFileServer();
app.UseDefaultFiles(new DefaultFilesOptions
{
DefaultFileNames = new List<string> { "index.html" }
});
app.UseStaticFiles();
app.UseRouting();
// global cors policy
app.UseCors(x => x
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader());
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints => endpoints.MapControllers());
}
}
}
