无法使用Visual Studio 2017将ASP.NET核心角度项目发布到Azure

Question

我在Visual Studio 2017（版本15.5.4）中有一个简单的Web应用程序，它是一个显示“Hello World！”的主页。来自后端。

Microsoft.AspNetCore.All的版本是2.0.7。

我在申请中有以下内容：

|    Backend            |   Frontend (Angular)     |
|  Model, Controller    | Service, Model, Component|

当我在本地运行应用程序时，它成功运行。但是，当我将其发布到我的Azure Web应用程序时，它会失败。

Web应用程序的诊断日志：

018-05-07 13:16:38.634 +00:00 [Error] Microsoft.AspNetCore.NodeServices: ERROR Response {
  _body: 'You do not have permission to view this directory or page.',

        'x-powered-by' => [Array],
        'date' => [Array] },

      Map {

        'x-powered-by' => 'x-powered-by',
        'date' => 'date' } },
  type: 2,
  url: 'http://pweb-dev-ferfer.azurewebsites.net/home' }

我在SO中搜索并应用了其他问题的解决方案，我按照建议here创建了web.config。

我建议Here没有ASPNETCORE_ENVIRONMENT Development。

这是startup.cs：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.SpaServices.Webpack;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

namespace WebApp
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        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();
        }

        // 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();
                app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
                {
                    HotModuleReplacement = true
                });
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }

            app.UseStaticFiles();

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

                routes.MapSpaFallbackRoute(
                    name: "spa-fallback",
                    defaults: new { controller = "Home", action = "Index" });
            });
        }
    }
}

型号：Home.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace WebApp.Models
{
    public class Home
    {
        public string msg { get; set; }
    }
}

控制器：HomeController.cs：

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using WebApp.Models;

namespace WebApp.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index()
        {
            return View();
        }

        public IActionResult Error()
        {
            ViewData["RequestId"] = Activity.Current?.Id ?? HttpContext.TraceIdentifier;
            return View();
        }
        [HttpGet]
        [Produces("application/json")]
        [Route("home")]
        public IActionResult Get()
        {
            try
            {
                Home home = new Home();
                home.msg = "Hello World!";
                return Ok(home);

            }
            catch (Exception ex)
            {
                return BadRequest($"Failed to get message {ex}");
            }
        }
    }
}

服务：home.service.ts

import { Http, Response } from '@angular/http';
import { Injectable, Inject } from "@angular/core";
import 'rxjs/add/operator/map';
import { IHome } from '../models/Home';
@Injectable()
export class HomeService
{
    myAppUrl: string = "";
    constructor(private _http: Http, @Inject('BASE_URL') baseUrl: string) {
        this.myAppUrl = baseUrl;
    }
    getMessage() {
        return this._http.get(this.myAppUrl + "home").map((response: Response) => response.json());

    }
}

组件：home.component.ts

import { Component, OnInit } from '@angular/core';
import { HomeService } from '../../services/home.service';
import { IHome } from '../../models/Home';
import { ActivatedRoute } from '@angular/router';
@Component({
    selector: 'home',
    templateUrl: './home.component.html'
})
export class HomeComponent implements OnInit {

    home: IHome;
    constructor(private homeService: HomeService, private route: ActivatedRoute)
    {
    }

    ngOnInit(): void {
        this.homeService.getMessage().subscribe(data => this.home = <IHome>data);
    }

}

更新：

如果我不使用角度服务，我可以发布网络应用程序。因此，如果我要求Home组件使用home.service来获取msg，则发布失败。

Answer 1

我的猜测是Azure ASP.NET Core Runtime尚未升级到2.0.7。一种解决方案是将Microsoft.NETCore.App软件包降级到2.0.6或等到Azure服务更新其核心运行时。
