javascript - Node JS 基本路由器被覆盖

Question

我的server.js文件看起来像这样:

var fs = require('fs');
var express = require('express');
var app = express();

// event listener
var events = require('events');
var eventEmitter = new events.EventEmitter();

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

// set the view engine to ejs
app.set('view engine', 'ejs');

// make express look in the public directory for assets (css/js/img)
app.use(express.static(__dirname + '/public'));

// set the home page route
app.get('/', function (req, res) {
  console.log('home page loaded');
});

app.listen(port, function () {
  console.log('Server listening on port ' + port);
});

我是 Node/表达新手，但希望得到一些澄清。我以为app.get('/', ...将处理默认功能。但它不是将消息记录到控制台，而是加载 index.html来自/public当我运行node server.js时.

这里覆盖路由功能的是什么？如果有帮助的话，快速版本是 4.11.1。

您遇到此问题的原因是 serve-static模块是您正在使用的中间件: express.static()

文档注释:

By default this module will send "index.html" files in response to a request on a directory. To disable this set false or to supply a new index pass a string or an array in preferred order.

即代替: app.use(express.static(__dirname + '/public'));

与: app.use(express.static(__dirname + '/public',{'index':false}));
