Node Express Middleware一次调用两次输出console.log()吗?

问题描述

关于一些Node + Express中间件的快速问题，该中间件在我的节点cmd提示符下两次向console.log输出1个调用.只是没有意义，并且想知道是否有人可以解释为什么这会发生在我身上.

just a quick question about some Node + Express middleware that is outputting 1 call to console.log twice in my node cmd prompt. It just doesn't make sense and was wondering if someone could explain why this is occurring for me.

server.js

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

//Outputs in my console twice?!
app.use('/', function(req, res, next) {
    console.log('Request Logged by Node+Express Server Middleware @ ' + Date());
    next();
});

app.get('*', function(req, res) {
    res.send('Hey world.');
});

app.listen(1337);

推荐答案

我知道发生了什么事情，Chrome正在向favicon.ico发出附加请求，因此输出翻倍.有道理.

I figured out what was going on, Chrome was making an additional request to favicon.ico, thus the double outputs. Makes sense.
