node.js页面两次刷新调用资源? [英] node.js page refresh calling resources twice?

问题描述

我有一个基本的node.js设置，但是我想我缺少一些东西.

I have a basic node.js setup, but I think I'm missing something.

我的main.js:

var a = require('./another.js');

var http = require('http');
http.createServer(function (request, response) {
    response.writeHead(200, 
    {
        'Content-Type': 'text/html'
    });

    response.write(a.saysomething('Hi there!') + '<br />');
    response.end();
}).listen(27182);

console.log('Server running at http://127.0.0.1:27182/');

我的another.js:

exports.saysomething = function (str) {
    console.log('in saysomething!');
    return str + ' hey there!';
}

问题是我的控制台两次输出in saysomething!.我想念什么吗?刷新页面时，我只希望有一个in saysomething!.

The issue is that my console is outputting in saysomething! twice. Am I missing something? When I refresh the page, I expect only one in saysomething!.

推荐答案

您的浏览器可能除了试图输入的URL之外，还尝试获取favicon.ico.尝试仅在命令行上执行以下命令:curl http://127.0.0.1:27182/

Your browser is likely trying to get favicon.ico in addition to the url you are hitting. Try to just do the command on the command line: curl http://127.0.0.1:27182/

此外，您可以为request.url添加日志记录.这将向您显示正在请求哪些URL.

Also, you can add logging for request.url. That will show you which urls are being requested.
