Question

我有一个socket.io项目，但它不允许我使用公共文件夹。我想启动hello.js

但我只看到

我尝试了一切，只是重新安装了node.js

var express = require('express');
var app = express();
var http = require("http");
var io = require('socket.io');
var url = require('url');
var fs = require('fs');

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

var server = http.createServer(function(request, response){
    console.log('Connection');
    var path = url.parse(request.url).pathname;

    switch(path){
        case '/':
            response.writeHead(200, {'Content-Type': 'text/html'});
            response.write('hello world');
            response.end();
            break;
        case '/socket.html':
            fs.readFile(__dirname + path, function(error, data){
                if (error){
                    response.writeHead(404);
                    response.write("opps this doesn't exist - 404");
                }
                else{
                    response.writeHead(200, {"Content-Type": "text/html"});
                    response.write(data, "utf8");
                }
                response.end();
            });
            break;
        default:
            response.writeHead(404);
            response.write("opps this doesn't exist - 404");
            response.end();
            break;
    }
});

server.listen(8001);

您没有使用Express应用，而是使用裸http.Server。如果您想使用Express应用程序（这是您使用static中间件的地方），您应该将http.createServer()的自定义回调换成app，如下所示：

var server = http.createServer(app)

然后，为了与Express集成Socket.IO，您需要关注this example。

express.static在node.js项目中不起作用
