angular - 带有.net核心2.2 ssr的角度8

Question

尝试使用 .net core 2.2 实现 angular 8.2.3 ssr build 的预渲染。继续获得：

处理请求时发生未处理的异常。InvalidOperationException：SPA 默认页面中间件无法返回默认页面“/index.html”，因为未找到它，并且没有其他中间件处理该请求。

我错过了什么？

启动.cs：

public void ConfigureServices(IServiceCollection services)
    {... services.AddSpaStaticFiles(configuration =>
        {
            configuration.RootPath = "ClientApp";
        });}


public void Configure(IApplicationBuilder app)
    {... app.UseSpa(spa =>
            {
                spa.Options.SourcePath = "ClientApp";

                spa.UseSpaPrerendering(options =>
                {
                    options.BootModulePath = $"{spa.Options.SourcePath}/dist/portal/server/main.js";
                    options.BootModuleBuilder = null;
                    options.ExcludeUrls = new[] { "/sockjs-node" };

                });

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

                //SPA fallback on root (for site)
                routes.MapSpaFallbackRoute("spa-fallback", new { controller = "Home", action = "Index" });
            });}

文件结构：

服务器.ts：

import 'zone.js/dist/zone-node';

import { ngExpressEngine } from '@nguniversal/express-engine';
import * as express from 'express';
import { join } from 'path';

// ssr DOM
const domino = require('domino');
const fs = require('fs');
const path = require('path');
import 'localstorage-polyfill';
// index from browser build!
const template = fs.readFileSync(path.join('dist/portal/browser', 'index.html')).toString();
// for mock global window by domino
const win = domino.createWindow(template);
// mock
global['window'] = win;
// mock document
global['document'] = win.document;
// mock localStorage
global['localStorage'] = localStorage;
// mock navigator
global['navigator'] = win.navigator;

import { AppServerModule } from './src/main.server';
import { APP_BASE_HREF } from '@angular/common';
import { existsSync } from 'fs';

// The Express app is exported so that it can be used by serverless Functions.
export function app(): express.Express {
  const server = express();
  const distFolder = join(process.cwd(), 'dist/portal/browser');
  const indexHtml = existsSync(join(distFolder, 'index.original.html')) ? 'index.original.html' : 'index';

  // Our Universal express-engine (found @ https://github.com/angular/universal/tree/master/modules/express-engine)
  server.engine('html', ngExpressEngine({
    bootstrap: AppServerModule,
  }));

  server.set('view engine', 'html');
  server.set('views', distFolder);

  // Example Express Rest API endpoints
  // server.get('/api/**', (req, res) => { });
  // Serve static files from /browser
  server.get('*.*', express.static(distFolder, {
    maxAge: '1y'
  }));

  // All regular routes use the Universal engine
  server.get('*', (req, res) => {
    res.render(indexHtml, { req, providers: [{ provide: APP_BASE_HREF, useValue: req.baseUrl }] });
  });

  return server;
}

function run(): void {
  const port = process.env.PORT || 4000;

  // Start up the Node server
  const server = app();
  server.listen(port, () => {
    console.log(`Node Express server listening on http://localhost:${port}`);
  });
}

// Webpack will replace 'require' with '__webpack_require__'
// '__non_webpack_require__' is a proxy to Node 'require'
// The below code is to ensure that the server is run only when not requiring the bundle.
declare const __non_webpack_require__: NodeRequire;
const mainModule = __non_webpack_require__.main;
const moduleFilename = mainModule && mainModule.filename || '';
if (moduleFilename === __filename || moduleFilename.includes('iisnode')) {
  run();
}

export * from './src/main.server';
