Question

我想在我的react组件中显示数据，但是当我设置API时，react不起作用。似乎中间件设置错误，或者我不了解.net核心和反应的方式。我知道我基本上使用.net核心运行两个不同的应用程序并做出反应，但是有人可以告诉我如何解决我的问题，只需将此API数据放入react页面？我首先是使用实体框架通过方法模型实现的。

我试图更改中间件，但最后总是显示API。当我更改API的路由时，react可以正常工作，因此一切都可以设置为react。但是当他们两个在同一条路线上时。我只看到来自API的数据。而且我只想从.net核心获取数据并将其显示在react组件中。

UsersController.cs

[Route("[controller]")]
[ApiController]
public class UsersController : ControllerBase
{
    private readonly MafiaContext _context;

    public UsersController(MafiaContext context)
    {
        _context = context;
    }

    // GET: Users
    [HttpGet]
    public async Task<ActionResult<IEnumerable<User>>> GetUsers()
    {
        return await _context.Users.ToListAsync();
    }

app.js

  <Layout>
    <Route exact path="/" component={Home} />
    <Route path="/users" component={User} /> //this one is a route for the api
    <Route path="/counter" component={Counter} />
    <Route path="/fetch-data" component={FetchData} />
  </Layout>

Startup.cs

公共类启动 { 公共启动（IConfiguration配置） { 配置=配置； }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

        services.AddDbContext<MafiaContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("DevConnection")));

        // In production, the React files will be served from this directory
        services.AddSpaStaticFiles(configuration =>
        {
            configuration.RootPath = "ClientApp/build";
        });
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        app.UseStaticFiles();
        app.UseSpaStaticFiles();

        app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller}/{action=Index}/{id?}");
        });

        app.UseSpa(spa =>
        {
            spa.Options.SourcePath = "ClientApp";

            if (env.IsDevelopment())
            {
                spa.UseReactDevelopmentServer(npmScript: "start");
            }
        });
    }
}

我想获取图片中显示的数据并将其放在react表中。

使用.net Core API
