我正在使用 NodeJS 和 ExpressJS 为简单的后端实现 RESTful API 服务器。我也在使用 BackboneJS 在前面渲染视图。因此，现在我有一个 index.html 文件，我想在客户端向“/”路由发送 /GET 时呈现该文件。这是我到目前为止所拥有的：

var express = require('express');
var app = express();
app.use(express.bodyParser());
var mongo = require('mongodb');
var mongoose = require('mongoose');

var Server = mongo.Server, 
    DB = mongo.Db,
    BSON = mongo.BSONPure;

var server = new Server('localhost', 27017, {auto_reconnect: true});


db = new DB('mydb', server, {safe: true});

db.open(function(err, db) {
    if(!err) {
        console.log("Connected to 'mydb' database");
        db.collection('items', {safe:true}, function(err, collection) {
            if (err) {
                console.log("Creating collection 'items'");
            }
        });
    }
});

var port = process.env.PORT || 3000;

app.engine('.html');

var listItems = function(req, res){
    db.collection('items', function(err, collection){
        var items = collection.find();
        console.log(items);
        res.send(items);
    });
}

var itemDetails = function(req, res){

}

var deleteItem = function(req, res){

}

var createItem = function(req, res){

}

var updateItem = function(req, res){

}

var routeHome = function(req, res){

        // What can I do here to render a plain .html file?

}

app.all('*', function(req, res, next){
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    res.header("Content-Type", "application/json");
    next();
});

app.get('/', routeHome);

app.get('/items', listItems);
app.get('/items/:id', itemDetails);
app.del('/users/:id', deleteItem);
app.post('/users', createItem);
app.put('/users/:id', updateItem);

app.listen(port);

console.log("Server started up on port " + port);

正如您所看到的，我已经完成了所有设置，除了我无法弄清楚如何将常规 .html 文件发送到客户端。我不需要渲染引擎，因为 Backbone 正在为我做这一切。我只想让 index.html 去客户端。

只使用express.static中间件怎么样？由于您使用的是 Backbone，您可能还需要发送静态 JS 文件： 

app.use(express.static(__dirname));

Place that somewhere before your other routes. It will try and find files requested in __dirname (the directory where your app.js file resides, but you can of course change the location where the middleware will try and find files), including index.html.

Step One, Remove app.engine(".html"),

Step Two:

var routeHome = function(req, res){
    // Do What Ever
    res.sendFile("index.html",function(err){ // Transfer The File With COntent Type Text/HTML
        if(err){
            res.end("Sorry, Error.");
        }else{
            res.end(); // Send The Response
        }
    })
}
