Question

我正在尝试在顶级Express js上创建一个angular7应用。我正在使用命令

ng build --watch

以便将渲染的文件映射为存储在服务器/公共目录中

下面是我用于快递的app.js代码

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

// var index = require('./routes/index');
// var users = require('./routes/users');

var app = express();

// view engine setup
// app.set('views', path.join(__dirname, 'views'));
// app.set('view engine', 'pug');
app.engine('html', require('ejs').renderFile); 
app.set('view engine', 'html');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('abcd',function(req, res, next){
  return res.sendFile(app.get('public') + '/index.html');
});
app.use('/',function(req, res, next){
  return res.sendFile(app.get('public') + '/index.html');
});
// app.use('/', index);
// app.use('/users', users);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error' );
});

module.exports = app;

这个想法是将所有路由路由到index.html文件。我有一条路线abcd，如果我尝试使用ng serve（角度7的开发模式），则可以正常使用。

i.e localhost:4200/abcd - works fine

但是在快递服务器上

localhost:3000/abcd - it is not working

我收到以下错误

Error: Failed to lookup view "error" in views directory "E:\ngME\server\views"

如何使localhost：3000 / abcd工作？我不想在有角的末端使用哈希。

弄清楚了。该代码应该是

app.use('*',function(req, res, next){
  return res.sendFile(__dirname + '/public/index.html')
});
