I start my server on my desktop PC runing windows 8.0 x64 and i forward port on router so then i connect for example from my phone going to xxx.xxx.xxx.xxx:3000 (current home ip address) all was working ok until i wanted to include external jquery from my "server" and css file style.css also from the server. 我在运行Windows 8.0 x64的台式PC上启动服务器,并在路由器上转发端口,因此例如我从手机连接到xxx.xxx.xxx.xxx:3000(当前家庭IP地址),一切正常,直到我希望包括来自我的“服务器”的外部jquery和来自服务器的css文件style.css。 I was reading on stack that there is some method called static path so i created inside my project folder "public" and i used:
我在堆栈上读到,有一种称为静态路径的方法,因此我在项目文件夹“ public”中创建了该文件,并使用了:
app.use(express.static(path.join(__dirname, 'public')));
which i found here: Node.js - external JS and CSS files (just using node.js not express) 我在这里找到的: Node.js-外部JS和CSS文件(仅使用node.js不表达)
but not single one method presented on stack worked, it keep returning several errors: 但是在堆栈上介绍的一种方法并不是可行的,它会不断返回一些错误:
is not an object
is not defined
or just server starts but file is not found is not defined
is not an object
或只是服务器启动但找不到文件
my hd path is: 我的高清路径是:
C:\Users\Patryk\Desktop\nodeproject\index.html
C:\Users\Patryk\Desktop\nodeproject\server.js
C:\Users\Patryk\Desktop\nodeproject\node_modules\...
C:\Users\Patryk\Desktop\nodeproject\public\...
It sounds like you might not have things in the proper order. 听起来您可能没有正确的顺序。 You need to declare your static paths before your routes.
您需要在路由之前声明静态路径。 Something like this:
像这样:
var express = require('express');
var app = express();
app.use(express.static(path.join(__dirname, 'public')));
app.get('/', function(req, res){
res.sendFile(__dirname + '/index.html');
});
Here is an updated version of your server.js
file: 这是
server.js
文件的更新版本:
var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.use(express.static(path.join(__dirname, 'public')));
app.get('/', function(req, res){
res.sendFile(__dirname + '/index.html');
});
io.on('connection', function(socket){
socket.on('chat message', function(msg){
io.emit('chat message', msg);
});
});
http.listen(3000, function(){
console.log('listening on *:3000');
});
